A while back, I had a lot of telemarketers were calling me daily, and I mean A LOT of them.

I got so frustrated with he calls that I decided I had to figure out a better way to handle those calls.

At the time, I was working with a PBX software called Asterisk, which is used to handle hardware interfaces and network applications for phone calls.

I needed a suitable side project and there was a version of Asterisk designed for Raspberry Pi, so I made a fun little answering service for myself.

Whenever a telemarketer called, I asked them to call back later, but to "my personal number", and gave them the number to my phone robot. (which had a pre-paid SIM card in a GSM dongle mounted)

When it received a call, it would play a pre-recorded phrase, wait for 1000 ms of silence and then play the next phrase.
After all 16 phrases had been played, it would start from phrase 7 again and repeat until the caller gave up.

I had this set up running for a while, and then added another robot for english speaking callers.

The calls stopped after a few months.
MISSION ACCOMPLISHED!

They've generated a very complicated PIN for my new SIM card… 🤔

You need a phone number to order a SIM-card in Germany. What.

my boss bought iphone 7 for testing...inserted his sim card and takes phone with him self all time...

Not a rant, just my thoughts :)
At November and October of last year I was very frustrated with everything - everything was annoying me and I was bored even with coding. I needed a break and do something different - go somewhere.

So we decided with friends that we will go to Georgia to spent there New Year Eve. Right now I'm coming back from airport by bus to my city aftertrip but can't sleep because I'm energized as fuck! Whole week without internet (sometimes we got open wifi to check buses or maps), without local sim card, without roaming, just our group and good attitude. We visited almost whole north of Georgia riding in taxis, marshrutka, even autostop, and it was fucking awesome.

So, when you are exhausted, take a break and regenerate your baterries, work is not everything! Just wanted to share this with you :) Can't wait to go to work in monday to write some code :) Life is beautiful!

On photo - my friend takes photo of Kazbek Mountain :)

Guys I need some help here! Google can't seem to help... opened up my moms boyfriends laptop to upgrade his RAM and to my surprise there was a SIM Card fitted inside, my first thought was that it could be chipped?

Paranoid Developers - It's a long one
Backstory: I was a freelance web developer when I managed to land a place on a cyber security program with who I consider to be the world leaders in the field (details deliberately withheld; who's paranoid now?). Other than the basic security practices of web dev, my experience with Cyber was limited to the OU introduction course, so I was wholly unprepared for the level of, occasionally hysterical, paranoia that my fellow cohort seemed to perpetually live in. The following is a collection of stories from several of these people, because if I only wrote about one they would accuse me of providing too much data allowing an attacker to aggregate and steal their identity. They do use devrant so if you're reading this, know that I love you and that something is wrong with you.

That time when...

He wrote a social media network with end-to-end encryption before it was cool.

He wrote custom 64kb encryption for his academic HDD.

He removed the 3 HDD from his desktop and stored them in a safe, whenever he left the house.

He set up a pfsense virtualbox with a firewall policy to block the port the student monitoring software used (effectively rendering it useless and definitely in breach of the IT policy).

He used only hashes of passwords as passwords (which isn't actually good).

He kept a drill on the desk ready to destroy his HDD at a moments notice.

He started developing a device to drill through his HDD when he pushed a button. May or may not have finished it.

He set up a new email account for each individual online service.

He hosted a website from his own home server so he didn't have to host the files elsewhere (which is just awful for home network security).

He unplugged the home router and began scanning his devices and manually searching through the process list when his music stopped playing on the laptop several times (turns out he had a wobbly spacebar and the shaking washing machine provided enough jittering for a button press).

He brought his own privacy screen to work (remember, this is a security place, with like background checks and all sorts).

He gave his C programming coursework (a simple messaging program) 2048 bit encryption, which was not required.

He wrote a custom encryption for his other C programming coursework as well as writing out the enigma encryption because there was no library, again not required.

He bought a burner phone to visit the capital city.

He bought a burner phone whenever he left his hometown come to think of it.

He bought a smartphone online, wiped it and installed new firmware (it was Chinese; I'm not saying anything about the Chinese, you're the one thinking it).

He bought a smartphone and installed Kali Linux NetHunter so he could test WiFi networks he connected to before using them on his personal device.

(You might be noticing it's all he's. Maybe it is, maybe it isn't).

He ate a sim card.

He brought a balaclava to pentesting training (it was pretty meme).

He printed out his source code as a manual read-only method.

He made a rule on his academic email to block incoming mail from the academic body (to be fair this is a good spam policy).

He withdraws money from a different cashpoint everytime to avoid patterns in his behaviour (the irony).

He reported someone for hacking the centre's network when they built their own website for practice using XAMMP.

I'm going to stop there. I could tell you so many more stories about these guys, some about them being paranoid and some about the stupid antics Cyber Security and Information Assurance students get up to. Well done for making it this far. Hope you enjoyed it.

Thanks to a small order mix up, I'm now sitting on 10 extra SIM cards for some IoT devices. I think my wife's going to kill me if she sees 10 Raspberry Pis show up at the door, but what else do you do with them?

We made a simple SMS application - when there is alert in a building, SMS is sent to specific range of numbers, based on the alert type. After a month we received invoice of approx. 10K € from the client, my colleague was supposed to pay
.
.
.

.
.
After checking the logs and running tests on module, we found out it was not our fault, client then told us he played with SIM-card while module was sending SMS and somehow he managed to fu*k up. I still don't get it, partially.. Mobile service provider doesn't give a sh!t about sending tons of SMS/hour? No warning, nothing..

Ahh.. Clients, right?

TL;DR: My devices all hate me and I needed to fix them all.

My Devices really love me.

I rooted my smartphone (LG G5) just yesterday. Everything went fine. Installed TWRP, SuperSU and some nice Apps that utilize root.

Today I was on the go (at CeBIT) and already had the Xposed Installer App on my phone, but didn't attempt installing it yet because I needed my phone for Maps and Messaging and the app had given clear warning about the bricking-potential.

So to the end of the day I get bored, send my last important Messages, installed the Xposed Framework...
... aaaand got stuck in a boot loop.

So I got on my way back home (thanks God I remembered all the trains I needed to take). On the way I had a lot of fun in the Recovery-Terminal and figured that I should be able to fix my phone with no problem at home because the installer made backups (unlike myself).

Coming back home and my pc was still running (should've shut down after installing updates).
The pc behaved odd and I couldn't shut it down properly, which led to cutting the power.
And upon booting my pc I got a ... give it a guess ...
...a bootloop (technically the animation just never ended).

So after I fixed my phone with my spare laptop (just transferred and executed the uninstaller for xposed) I fixed my PC too, which had an old broken dkms-driver.

The odd thing about this is, that this isn't technically a rant. I guess you can confirm that you can't find any swear words.
Because I ENJOYED fixing the devices. I already fixed my pc a couple of times was well as unbricking my rooted phones, so there was fairly little research involved.
I guess I'm now offically twisted.

Now, after my smartphone backups are transferred, I'Ll take my device apart and replace the camera glass which arrived today (and hope, no pray, that my sim card does still work after that)...
... after I blatendly copied a meme to get more attention. 😉

My friend dropped her phone and it doesn't turn on anymore, but she has a dual-SIM spare phone. So the problem didn't seem too bad at first. I told her I'd help her with the backup restoration, set everything up on her new (old) phone.
After 30mins of trying to restore the backup from her old phone and moving the SIM card to the new phone...

"But I didn't have a backup and the SIM card tray isn't working. Can you also help me recover my 10 000 pictures and songs?"

I guess I'm done here

Just did a transplant on my friend's phone. He dropped it one too many times, and fucked it up real bad.

We were first going to simply put his SIM card into another phone. I had an old S6 that bricked itself during an update before I really knew much of anything about phones, so I dug it out and spent a day trying to restore it with heimdall, adb/fastboot, and eventually odin when I found a laptop with windows. Unfortunately it's a Verizon phone, and because Verizon likes to keep a tight chastity belt on everything, it was pretty much impossible to unbrick. After giving up with finding a custom recovery or flashing a stock ROM, we moved to Plan B.

We took both phones apart, switched the boards, switched the SIMs, and he now has a working phone in much better condition than before he dropped it seven feet from his girlfriend's bunk.

It's always fun to make life from two dead things.

I've got a teacher (math) in the university that let us use our phones as a calculator in the exam but without sim card and of course no wifi. I've spent a few hours programming a very ugly CLI app which let me calc and show me the steps of every type of exercise.
Another probe that programming can save your ass.
The exam wasn't difficult but basically they tell you to solve a few problems applying different methods, that hasn't advantage from others.

It's sometimes really anxiety inducing thinking that all data could be gone, if somebody decides to kill/discontinue/crash [see gitlab shitting 6 hours of data due to fucked backup strategy and shitty seperation of servers] your account/service, be it server, git-repos, backups, chrome syncs, games, music, sim card, ..

But there's simply no way of having a backup of absolutely everything (ignore DRM) - especially automated and abstracted away from you, so you don't have to do all that shit yourself

Just got a new car with a 7" touchscreen and an HDMI interface that is extremely easy to disable the safety features on... Then an idea immediately hits me, a development board, a SIM card module, and I have dedicated Spotify, and navigation. How cool is that!?

Man soo much has happened. I broke ( 2. Months ago ) my main phone = Oneplus 1. Then I proceeded to throw my sim card into my backup phone = iPhone 4. So within that time I've started working at the same remote company my brother/ I work for as a python dev. But I am deffinatly learning as I go. Been there a month this week! So with this being my second job. I finally had enough money to buy nonessential so 4 day ago I ordered a new glass and digitizer assembly for my main phone it came today I fixed in just under 2 hours as my first phone repair. Pretty proud

I've had a Xiaomi Mi 8 for a few months now. Although I'm impressed by what I got for the amount I paid (a phone that cost about $250 for 6GB RAM, Snapdragon 845, Android 9 and premium build quality is quite a steal), it definitely comes with a consequence.

MIUI (specifically MIUI 11) is godawful. It is single-handedly the worst Android ROM I've ever used since my shitty Android 2.2 phone back around 2010. If you're gonna buy a Xiaomi phone, plan to install Lineage OS on it (but even that's a pain which I'll explain why later).

- Navigation buttons don't hide while watching a video.

Why? God only knows. The ONLY way to bypass without root this is to use its garbage fullscreen mode with gestures, which is annoying as all hell.

- 2 app info pages?

Yeah, the first one you can access just by going to its disaster of a settings app, apps, manage apps and tap on any one.

The 2nd one you can access through the app info button in any 3rd party launcher. Try this: Download Nova launcher, go to the app drawer, hold on any app and tap "app info", and you'll see the 2nd one.

Basically, instead of modifying Android's FOSS source code, they made a shitty overlay. These people are really ahead of their time.

- Can only set lock screen wallpapers using the stock Gallery app

It's not that big an issue, until it is, when whatever wallpaper app you're using only allows you to set the wallpaper and not download them. I think this is both a fuckup on Xiaomi and (insert wallpaper app name here), but why Xiaomi can't include this basic essential feature that every other Android ROM ever made has is beyond me.

- Theming on MIUI 11 is broken

Why do they even bother having a section to customize the boot animation and status bar when there's not one goddamn theme that supports it? At this point you're only changing the wallpaper and icon pack which you can do on any Android phone ever. Why even bother?

They really, REALLY want to be Apple.

Just look at their phones. They're well designed and got good specs, but they don't even care anymore about being original. The notch and lack of a headphone jack aren't features, they're tremendous fuckups by the dead rotting horse known as Apple that died when Steve Jobs did.

Xiaomi tries to build a walled garden around an inherently customizable OS, and the end result is a warzone of an Android ROM that begs for mercy from its creator. Launchers integrate horribly (Does any power user actually use anything that isn't Nova or Microsoft launcher?), 3rd party themes and customization apps need workarounds, some apps don't work at all. People buy from Xiaomi to get a high end budget Android phone at the price of some ads and data collection, not a shitter iOS wannabe.

They really, REALLY want you to have a sim card

If you don't have a sim card and you're using your phone for dev stuff, you're a 2nd class citizen to Xiaomi. Without one, you can't:

- Install adb through adb
- Write to secure settings
- Unlock your bootloader and get away from this trash Android ROM

What's the point? Are they gonna shadow ban you? Does anyone contact them to unlock their bootloader saying "yeah I wanna use a custom rom to pirate lizard porn and buy drugs"? They made this 1000000000x harder than it needs to be for no reason whatsoever. Oh yeah and you gotta wait like a week or something for them to unlock it. How they fucked up this bad is beyond me.

So yeah. Xiaomi. Great phones, atrocious OS.

Had a SIM card for a week. Wasn't able to log into their service portal. Internet service was shitty as well. I recalled the contract.

Now they have sent me an email informing me of a bill which is stored in the online portal, and i have no idea for what this is, or how to find out.

I miss letters :-(

What is it that service providers wont send this stuff out as PDF?

*boomer-rage

My phone suddenly is stuck in a reboot loop.
all solutions did not work (Safemode, Recoverymode etc)

It was time for a new phone.

well... most of my logins have now 2 factor authentication. That got me thinking:

imagine that you lost all your trusted devices in a house fire.
you cannot get in your email because of you need to verify.
you cannot buy stuff online because your phone gets a message.
and in certain cases you cannot even get in your password manager of the same reason.

I know that there are recovery codes and other solutions to this.. oh boy you are F*cked when you don't have your phone.

Everything turned out okay, Sim Card in different phone for messages. And new phone works like a charm :)

What is your opinion on eSIM (embedded SIM)?

Now that Apple has built the first smartphone without modular SIM, it is, as history shows, only a matter of time until the same vendors who mock Apple for doing this will hypocritically follow Apple in implementing it themselves. There will be an outrage, but it will fade and the new restriction will be tolerated.

To me, "eSIM" appears like an euphemistic / euphemSIMtic (pun intended) marketing term, like calling non-replaceable batteries "eBatteries" ("embedded batteries") would be. It is less modular and more locked-down.

NCIS New Orleans
"If I had the sim card I could track the gps..." now... I'm fairly certain the phone gps is independent of the SIM card?

Installing COSU devices. Need to setup 200 Androids. I boot up number 43 and it's set to Chinese language. I switch to English. It registers with the network.. WTF there is a sim card inside. =D And it was in a sealed package.

Now I am a proud owner of some poor bastards China Unicom WO sim card. =D

Second Rant incoming!

I have a Elephone p9000 (China Smartphone). Great Value for it's price if you don't mind a shit camera.

Also, this is actually my second model! I cracked my screen and tried to replace it. Somehow I managed ti puncture the battery and nearly set my house on fire but that is another story.

This rant is about how the sd/sim-card read is FAILING ME! Everytime I call someone, my sim-card ejects spontaneously, thus ending the call. It's so goddamn annoying having to recall the same person every two minutes...

I tried inserting the sim-card in the other slot because it has dual sim but nothing changed...guess I need a new Phone. FML

So I've just moved to Amsterdam from London. What prepaid/pay as you go Sim card you recommend me to get? I don't call or text much, data is more important to me

"Ughh, you're such a lazy person. Why don't you finish it instead of making me do everything afger I asked YOU to do it"

I am so fucking done playing family technicman for you. I copied all of your data from your old phone to yojr new one. I set up everything except personal accounts because I respect privacy. You only need to insert your damm sim card.

And don't you even try giving me that "I tried but could not do it, it's just to complicated"

I could buy the same phone, throw it at you and pay the lawyer if I would get one cent for each time you said that.

!rant

One of my housemates had a problem with her iPhone (an iPhone 4), which was showing her a black screen. I asked her if she had tried to restart it, and she said she'd taken out the SIM card and and put it back in and it was still giving her a black screen. I told her that holding the lock and home buttons at the same time for a few seconds restarted the thing. Seconds later she was messaging me in all caps saying it worked.
I guess the "turn it off and on again" really does work LoL

What is it with this trend if having a SIM card in every modern car? Fucks sake, can't even find one that can be sold without -_-

Trying to add money to a prepaid SIM card today. Their website is a mess. Plus and minus buttons were not functioning, so my only option was to add 15 euro. Checked the console, no errors. Tried triggering the buttons jQuery, no luck. Found a data value attached to the submit button set to 15. Changed to 10, clicked submit, and BOOM, it worked! You just got engineered!

After I paid, I was curious, went back and set it to -15, and tried it again. Unfortunately, they know about backend validation.

My non-tech cousin just asked me if he can use the second SIM slot in his phone as a slot for inserting a SD card since he doesn't have a second SIM and the phone does not have a memory card slot. I said yes 😂😝

So I wonder if anybody on here has ever come across the LG G3 flickering screen issue.

I bought a LG G3 about 2 years ago. Fantastic phone.. Until all the issues started appearing.
First of all, the glass started lifting off on the left side of the phone, exposing the backlight layer, because the phone somehow managed to bend (insert iphone joke) inside my pocket. I was okay with it since it was a minor visual thing and didn't affect anything.
About 6 months ago the phone started lagging like crazy, and it kept getting worse and worse. It's so bad right now that Twitter will rarely fullscreen images, apps crash all the time, and occasionally the phone freezes to the point where it won't even react to the lock button.
About 2 weeks ago I started getting messages that my sim card was removed, and the phone starts rebooting itself. This would sometimes happen 10 times a day.
I was already pissed at all of these issues and in a desperate need of a new phone, but on Sunday a brand new issue appeared!
The phone's display randomly shut off, then wouldn't want to turn on, and occasionally turn on just to fade out or flicker away.
I of course went to google to see if anybody else has this issue... And it turns out that youtube is full of videos about it. Apparently the overheating issue these phones have slowly ruins the solder on the chips, which in turn creates a poor connection and causes these issues. The only way to solve it seems to be to reflow the chip, but others that tested that only got it to work for around 2 weeks before the issues started reappearing. I haven't tested it myself yet, but after disassembling, fucking around with it, and putting it all back together 3 times I sort of got it to work to the point where I can use it for several minuted before the displays fails. While writing this rant the display only quit on me once at the very beginning.

What I'm wondering is, why is it that nobody at LG decided to address the heating issue by perhaps throttling the CPU more? And I heard the G3 isn't the only LG phone with these issues?
This crap made me lose all my trust in the company. I wanted to upgrade to a G6 or V30, but because of this crap I think my next phone might be a Xiaomi.

This rant is now so long that it's barely even a rant or on topic. I think I should end it here since I have nothing more to say other than the LG G3 is a beautiful but crap phone, oh, and the new iPhone 8 is a flop

today I forgot to check the balance of my prepaid sim card. (it was < 2€)
I just received a notification from google that payment for devrant++ has been rejected.
F*uck!
I recharge my sim with paypal.
but google play it's still in error.
"add a different payment method"
fine.
I choose to add paypal....
*type username*
*type password*
*processing*
"your paypal account can be added because it's blocked; contact paypal."
wtf? I used paypal 10mins ago.

*login using paypal app*
everything works.

ok fuck you google.
as soon i will solve this issue i will restore the ++ subscription.
(if it will be disabled)

I got a SIM card activated for my dad yesterday. Here in SA you need to verify your identity to get the card activated. But the company's systems were offline yesterday while I got it from another distributor of theirs 2 shops over. Now a day later they tell me I have to go and get another one because the one I got won't be activated because of it being offline. Something about it being assigned to me while it is offline makes it not work.

WHAT BULLSHIT? WHO THE HELL CODES THAT TRIPE TO FAIL TWICE AS HARD AS IT SHOULD? IT MAKES NO SENSE IF THE THING IS OFFLINE FOR THIS TO HAPPEN.

And yet, with Telkom's legendary poor service I know the service people are not lying. They just don't know what the hell is going on.

Very surprised to know that an IPhone can geotag the photos even when the SIM card is not active and no means of any internet connection(wifi or someone 's hotspot)
My IPhone 7 is contracted in US with AtAndT,quite obvious it doesn't work in India(I am on vacation).
Still,the pics recognized the Taj Mahal,Red Fort,my locality(Bangalore-South),etc..

Birthday Present: Lenovo X1 Carbon with old Sim Card from previous Owner! ( Turn out the Laptop is used and not Fresh)

So I'm back on Shitty Windows 10! or ChromeOS Flex instead of ChromeOS natively on a Lenovo Chromebook!

Hello guys, mom just got an iPhone 8 from a friend who lives in the US and it seems it's network locked as no Nigerian sim card works. What are my options in removing this lock?

yesterday, I just swapped my sim card for some time with another. Placed it back....and voila! I can't enable data connection. I lost all my apn settings. To add to this, neither is it auto fetching the apns, nor i can manually change it! It shows some fucking error "apn settings not available for this user". I have another phone with same android version (lollipop) and everything works smoothly on it. These guys just broke everything after giving an upgrade from kitkat. Auto brightness stops working after a few hours, random reboots.... This is it... bye bye stock rom!

The SIM card saga goes on:
To verify yourself, you need to go to some postal office and show them your ID and stuff. Not that this is complicated or anything (well actually, it is. Welcome to 2018 in Germany. We use more papers than potheads for the simplest shit), but you need to have a valid ID. Valid as in NOT EXPIRED. What the fuck. Why does my ID expire. Do I stop existing 3 years after getting it? What does it mean if it is, why is it culpable to have your ID expired. And who gets charged for having none, I mean obviously my ID doesn't identify me anymore?
What the hell man. I don't exist for 6 months now. Am I law free as not identifiable entity or how does it work?

And now the real question:
We got something called Bafög in Germany. Basically you get a bit money while studying. (I still work tho, I don't get really much from it.)
To apply for it, you need some tax number, which seemingly can be seen as a proof of my existence and my identity.
Why is this enough, why don't I need a valid ID there?

Germany is weird man. On the one hand government is all social and you get help if you need it but on the other hand you need to sacrifice 17 virigins to apply for said help..

Alright devs, in the US, can I not get a SIM card on which I simply put some money, and can use that until it runs out? Seems there is a 30-day limit tied to everything!!! I don't need data for 30 days!!!

This is totally possible in Europe, what is going on with regulation in US? Seems like it should be illegal.

It's these individually tiny annoyances in products and software that together form a huge annoyance.

For example, it's 2022 and Chromium-based web browsers still interrupt an upload when hitting CTRL+S. This is why competition is important. If there was no Firefox, the only major web browsers would, without exception, have this annoyance, since they're all based on Chrmoium.

I remember Chromium for mobile formerly locking scrolling and zooming of the currently viewed page while the next page was loading. Thankfully, this annoyance was removed.

In 2016, the Samsung camera software was updated to show a "camera has been opened via quick launch" pop-up window when both front and rear sensors of the smartphone were covered while the camera was launched by pressing the home button twice, on the camera software Samsung bundled with their custom version of Android 6. What's more, if that pointless pop-up was closed by tapping the background instead of the tiny "OK" button or not responded to within five seconds, the camera software would exit itself. Needless to say, this defeats the purpose of a quick launch. It denies quick-launching while the phone is in the pocket, and the time necessary to get the phone out could cause moments to be missed.

Another bad camera behaviour Samsung introduced with the camera software bundled with their customized Android 6 was that if it was launched again shortly after exiting or switching to stand-by mode, it would also exit itself again within a few seconds. It could be that the camera app was initially designed around Android 5.0 in 2015 and then not properly adapted to Android 6.0, and some process management behaviour of Android 6.0 causes this behaviour. But whatever causes it, it is annoying and results in moments to not be captured.

Another such annoyance is that some home screen software for smartphones only allows access to its settings by holding a blank spot not occupied by a shortcut. However, if all home screen pages are full, one either needs to create a new page if allowed by the app, or temporarily remove a shortcut to be able to access the settings.

More examples are: Forced smartphone restart when replacing the SIM card, the minimum window size being far too large in some smartphones with multi-windowing functionality, accidental triggering of burst shot mode that can't be deactivated in the camera software, only showing the estimated number of remaining photos if less than 300 and thus a late warning, transition animations that are too slow, screenshots only being captured when holding a button combination for a second rather than immediately, the terminal emulator being inaccessible for the first three minutes after the smartphone has booted, and the sound from an online advertisement video causing pain from being much louder than the playing video.

Any of these annoyances might appear minor individually, but together, they form a major burden on everyday use. Therefore, developers should eliminate annoyances, no matter how minor they might seem.

The same also applies for missing features. The individual removal of a feature might not seem like a big of a deal, but removing dozens of small features accumulates to a significant lack of functionality, undermining the sense of being able to get work done with that product or software when that feature is unexpectedly needed. Examples for a products that pruned lots of functionality from its predecessor is the Samsung Galaxy S6, and newer laptops featuring very few USB ports. Web browsers have removed lots of features as well. Some features can be retrofitted with extensions, but they rely on a third-party developer maintaining compatibility. If many minor-seeming features are removed, users will repeatedly hit "sorry, this product/software can not do that anymore" moments.
