Simcard stopped working (Bizarre case)

Today out of the blue my sim card stopped working.
1) I tried the simcard on my friend's phone, it works fine!
2) I tried my friend's simcard on my phone, it worked!
So for some reason my phone rejects my simcard.
I got desperate and decided to do a factory reset which didn't help.
My phone is running stock android and it's perm rooted.
I have no idea what to do. Any suggestions please?
Thanks.

If you sim stoped working talk to your mobile provider

My sim card works on other phones, so I think it's something else.

Oh... sorry I misread. It must be a defect or something. Have you tried flashing other roms. If it keeps happening get it replaced

So I spoke to tech support and they said they will send me a sim card free of charge this time. But the guy informed me that my phone is burning the sim cards because it wasn't designed to work with HTC devices, so it's reading the simcards improperly ending up damaging it.
He said I need to modify some code on the phone so it wouldn't burn the sim cards.
Any ideas?

Now the sim card suddenly started working........... that's too odd.

Does your SIM get disconnected?

Sometimes I unlock the phone and I find it on the SIM unlock screen, where you must enter the PIN... It happens when I'm at work, where there is very bad signal... Does it happen to you also? Can it be related to the bad signal which forces a sort of SIM reset or could it be related to a bad SIM (it was a standard size SIM which I've cut with a SIM cutter).

never happend to me

Ive had mine for just over a week and a bit and where i work my signal isnt great however i havent experienced anything you mentioned above. It may be due to the fact your running a normal sim rather than a micro one and the fitting doesnt quite match.

I've replaced my self-cutted sim with a new micro-SIM, for 8 euros... Hope it solves the problem

Today I've experienced another "SIM reset" at work, where I have very poor signal... It asked me to enter the PIN.. can it be a radio bug not solved by fw 1.28?

T-Mobile will give you a replacement SIM of the correct size. Try that first. Your microSIM may not be making proper contact.

Thats what i'd do.
Unless you're constantly swapping between your nexus and a phone with a micro sim slot, i'd go get a full size sim card from t-mobile.
The store can swap it immediately, and probably wont charge you.

I went to T-mobile and they gave me a replacement sim , but that didnt work so i called up samsung and i still had warrenty so i sent it in , i just hope it doesnt take too olong :/

"your sim card does not allow the connection to this network" HTC One X

Hey guys!
Ive just woke up 2 days ago with this error "your sim card does not allow the connection to this network" and I have no network signal.
Tried everything, I was on Ordroid 14.0.0 , installed 15.0.0 now im back on stock firmware, still nothing, tried a different sim card and doesn't work (only one from a different country its working)
The sim card I was using for 6 months on this phone is working on any other phone.
Can anyone help me with this issue please?
Thank you very much!

2 scenarios:
1. Your SIM card tray is busted (hardware)
2. Your carrier has banned your IMEI
Did you buy your phone new or used?

Ive gave my Samsung Galaxy S2 for this one and that guy told me it doesn't have the papers anymore.
How come it worked fine for 6 -7 months?

I don't wanna make any scary speculations but it is possible that the phone was stolen/lost and it eventually end up in your hands. Later the original owner requested the carrier to ban the device from it's network.
Again, just thinking out loud here... You should ask your carrier.

I got the same problem with my HTC One S!
1) I check the ESN and it comes available not reported stolen.
2) I did Factory reset and clear all storage as well = nothing!
3) When i go into phone settings it reads the sim card because you can get the phone number and everything other info from the carrier but nothing! Even i change from GSM/WCDMA Auto to GSM only and back and picks up the Network but it doesn't let me connect... im giving up, i just dont know why keeps giving me the same message...:crying:

Problems with new SIM card LG G3

Hi there,
I am a so far satisfied owner of a G3 but since 10 days I have been having an issue with my G3 and I wanted to ask around if someone here has an idea or some thought that could help.
My situation is the following:
About 2 weeks ago I switched my mobile service provider. When my new SIM card from my new provider arrived I tried the SIM card in my G3 but there was just the massage "no sim card found" and no possibility to type in your PIN. So I thought maybe I got a defective SIM card, it happens. I ordered a new one but the problem remained with the new card in my G3 aswell, still no pssibility to type in my PIN. So I tried troubleshooting and started trying the SIM cards in diffrent phones. In other phones the SIM card from the new provider worked perfectly and I was able to type in my PIN like it should be. When I tried putting other SIM cards in my G3 (from my Mom, Dad etc. and also from different providers) none of them worked in my G3. Even my sisters SIM card from the same new provider AND she has also a G3. So far it seems that the my G3s SIM card reader is broken.
The weird thing is that when I put in my G3 my old SIM card from the old provider the prompt to type in my PIN appears as normal as ever. If I type in my PIN the phone accepts the PIN normally. There is just no reception which is normal because I am not with my old provider anymore. I also have to add that the phone appears not to have SIM lock. I bought it from a private seller but he bought the G3 with a vodafone contract and I was with O2 at that time and the phone worked perfectly. Just until I switched from O2 to Congstar (Telekom) the problem began.
So I thought I just send it back to LG because I still have warranty on the device. The phone is rooted so I need to admit that it was not that clever to send the phone in without rolling back the rooting. Today I got a letter from the repair service from LG with an estimate of cost which means no surprise, no warranty for me. You guess right, the reason is the rooting they write they need to change the whole mainboard. For me this sound like plain bull**** because on the document they send it seems like the first thing they check is a rooting and if the device is rooted then thats the cause. But ok it was pretty stupid from me not to unroot it, I know.
Now I wanted to ask you if someone had a similar problem with their G3 or has an idea what the cause could be. Like mentioned above with my old SIM card the phone worked normally. Just the new cards and all other cards, even another O2 card did not work. Is it possible that just one and only one SIM cards gets accepted from the phone?
Sorry for the long post. I am thankful for any advice.
Best regards,
Patrick

I'll have my phone back tomorrow. If someone still has an idea I would be very thankful about some thoughts or suggestions.
Thanks!

It seems your phone is Sim locked.
You need to find the unlocking code that you need to put in the hidden menu.
Google for LG G3 Sim unlock.
Sent from my phone

Hi,
thanks for your reply! Iam not sure it is because of sim lock- Because the phone came with a vodafone contract but when I bought it I was with O2. And with my old sim card from O2 the phone worked perfectly. Weird is that when I put in a different O2 sim card the pin prompt also did not appear. Same with any other sim card ...
Thanks,
Patrick

Or did maybe someone have a similar experience with a different phone?

Hi again,
I tried some more things but still nothing helped.
The things I tried were:
- unrooting the phone and factory reset
- reflash radios
- try completely diffrent rom (CM)
Still I have no idea what the cause could be. Maybe the sim card reader is just broken. Just weird that it reads my deactivated sim card.
I would really appreciate it if someone has an idea or some similar experience..
Thanks!

You can buy an unlock code for 3.5-4€ , works for any LG G3 variant
Try it

Ok, thanks! I will try it!

So I just looked at what I have to do and tried the combination 2945#*855# to see where I have to type in the code. The thing is when I choose any one of the appearing options like netlock etc. the phone says "this phone is permanently locked" and there is no possibility to type in any code...
How the hell is my phone completely locked...
