SIM card problems - Galaxy 3 General

Hi, I have a serious problem with my G3 (Kyrillos' ROM v5.5). Sometimes my phone doesn´t recognize SIM card during its running. I switch it on normally, PIN code is correct, SIM card is loaded and after some mins or hours it all of a sudden can´t read it and I have to remove SIM and then insert it again. Is it hardware problem or what´s wrong with my phone? Thanks

Try to clean your sim with a tissue or something. I had the same problem once, cleaned the sim card a bit and now its gone.

I cleaned it, we´ll see how it´s gonna work

I had this problem on my phone after a bad flash. I think it was the modem image or something. Flash it back to the stock JPM and flash it to your normal firmware you use to do a full reset.

please help i am desperate

i bought a t-mobile hd2, it is unlocked since it doesn't ask for a code, if i insert sim card it gets freeze every couple of minutes i tried to flash new rom change radio spl, nothing worked. only if i take the sim out it works like charm but the moment i put the sim in i freezes, i tried different sim same problem ? i did search cant solve my problem
If it's your SIM card, just take it into T-mobile, they'll replace it free & quick. But make sure you have the stock rom on it when you take it in or it will void any warranty.
If it's your microSD card try formatting it to your phone. If that doesn't work it's probably corrupt. Not sure if it's covered or not.
Sorry I couldn't be of much more help, but I'm sure one of these brilliant minds on here can help more.

It didn't ask for a code? so you aren't with T-mobile then I'm guessing..
You might wanna try a hard-reset, and if there's an SD card in there try taking it out.

[Q] No sim card detected

Hi everyone,
I messed a bit with my d802 and finally i used the lg support tool to get it back to stock, but now it can't read my sim card all of a sudden (no sim card inserted).
So the question is where are the sim card files, in the kernel or the rom or the baseband ? and how to get them back so it reads my sim card.
I'd be happy to bring you more info on the problem.
Thanks in advance.

I had the same problem, reflashing the 10B firmware then upgrading to the OTA 12A fixed the issue.

Did you sort this?
If not try this
Power OFF the phone. Remove the SIM card completely for at least 1 minute.
Re-insert the SIM card, Power ON.
If it works, I'll tell you why...

OK - good. This is a fairly common "problem" when making significant ROM changes - but doesn't always happen.
In basic terms...
When the phone is powered OFF, it isn't actually completely OFF. Some "parts" are still powered. The SIM card and its register are "parts" that remains powered and the register is sometimes overwritten when a ROM is flashed. This means when the new ROM boots, the SIM card and the register are different, hence no network as the phone assumes a fault.
The SIM card needs to be removed with the power off (NEVER with it on) so the phone detects a SIM swap and the register is refreshed.
TIP: Before flashing a new ROM - always remove the SIM card (with the Power OFF).

No SIM CARD after official lollipop stock rom update
Hi,
I have updated my LG G2 F320L (Korean Version by UPlus) on Lollipop successfully.
But now my SIM Card is not detecting. I am in Pakistan and dont know what to do now.
I tried to restart the phone with no sim and with sim and also flashed the same stock rom again but still no sim card.
I also tried to put the following codes i.e. for IMEI *#06# and for SIM Unlock menu 2945#*320# which didn't work too.
I also did factory reset many times with sim and without sim.
Tried to do rooting throguh Towelroot and Stumproot but no success.
Dear All, Please help as what might be the problem.

Unfortunately I don't have a solution yet, but I wanted to point out that I am in the same situation ATM. German lg g2 though. Please any new input would be highly appreciated.
Issue Resolved
Hi I took the phone to the android expert in mobile market in my area SADDAR AREA-RAWALPINDI CITY-PAKISTAN. Where he highlighted that the ROM, Baseband and Radios where not compatible as well as my phone had some EEPROM problem as well. So he hooked a small box like USB device and pushed the ROM into it via OTG along with the new stock ROM. Now my phone is working perfectly fine and I am more than happy and thankful to the expert. My current stock ROM is lollipop version: 5.0.1

I know this thread is hella old but, I stumbled upon this (after returning to the G2 temprorarliy - had it back in 2013/14) after restoring a stock LG ROM backup and it wasn't recognizing my SIM card. Anyways, this method worked for me to get the phone to recognize my SIM. Thanks for posting this.

Hi ,
SIM card problems if they are not hardware related , they are usually caused by IMEI ( efs folder) or wrong modem if you have and efs folder backup , restore it.
What S4 you have , what rom do you have , what modem do you have??
When it fails to recognize the sim card check your IMEI dial *#06#
Hello,
i have tried everything i can think of without any success. It is a Samsung Gt-I9505.
The problem with checking IMEI when it does not recognize the SIM card is that i can't do anything but restart it. There is a error message with restart as the only option.
Now it is doing it as soon as it starts up. I never have to remove the SIM card so the phone recognizes it, just a simple restart without touching the SIM is enough.
I am on the last official Australian ROM. Baseband I9505XXUGNH6, Hernel 3.4.0-2309103 Build number KOT49H.I9505XXUGNH6
I have tried it with another SIM and same thing happens so it is not because of the SIM card.
Any ideas what else to try? I do not have any back ups of anything.

Hi mate,
Your case is not clear , it does not look like firmware but i would not discard that possibility , do you have stock or custom rom? try to reflash
Also there is a chance for what you tell me that the sim caddy may be defective

I am on official ROM, flashed over ODIN. You recommended to check the IMEI when this happens but i can't because the only option is to restart the phone.

Please more details
When you have the no sim errors it does not allow you to dial *#06# ? why does the phone freeze ?

No, it does not freeze but a pop up shows with only one option "restart". I tried to touch the screen, home or return button but nothing works but touching the restart button.

I see, is strange if you said that whith a reboot works fine it make me think more in a hardware issue...maybe the sim caddy..
This phone is driving me crazy. The replacement SIM reader arrived today and i replaced it. Now it does not find any SIM, just getting NO SIM error as soon as it starts up. I tried putting back in the old reader but the same happens.
Anyone any idea what to do or just recycle the damn phone?
Come on guys there must be someone with an idea

[Help] Sim card not inserted problem after flash, likely a software issue

So for ages i was getting no sim card inserted on my I9505 and figured it was a hardware problem as it would work sometimes if i pushed the tray really hard and so i replaced the sim card tray and all was working for a few days. I then decided to flash a new rom and straight after the flash all im getting is no sim card inserted.
Ive used odin to flash the stock firmware but still get the message. Ive used the airplane trick also with no luck.
Im totally convinced its a software problem because it happened instantly after a flash and ive only recently replaced the sim reader.
Any help would be appreciated.
hii , i guess you have imei problem , chech for #06# if your email code match the one below the battry.

It was AntaresOne & Alucard24's cm12 build. I tried flashing the latest modem and obviously when i went back to stock using Odin an older modem but correct one was installed.
Anyhow, i actually believe it was a hardware problem again. I think that when flashing a new ROM it gets very hot and this can cause problems with the Sim reader. So i took apart the phone and basically used some duct tape to make sure the pop connector thingy is securely pushed down and also the Sim tray. It seems to be working so far.
I will flash a ROM just to make sure it doesn't happen again.

"No SIM card detected" & "No service"

Hi all,
I have a problem with my XC, i hope there's someone here who could help me out with this .
I get a SIM card error when i start the phone. After a while (5-10 mins) the error transforms into "No Service" as if the phone now detects the SIM card but has no service whatsoever.
Things i did to my phone prior to this:
- unlocked bootloader
- installed custom recovery
- root
- installed custom ROM
- drm fix
The phone did function properly for a few months actually after these operations without a SIM card error even once. But then i tried to install custom ROMs again (and i'm sure didn't flash ROMs not suited for XC) -actually tried to install "existenz" ROM but i did get a bootloop so i -once again- did the usual procedure with flashtool and flashed a firmware to set everything back to stock as close as possible. That was, when i started to get the SIM card errors. After several restarts (cold and warm) the phone sometimes recognized the SIM card and i could use the phone normally. But this was true only till the next restart, where i got the same SIM errors again.
Things i tried:
- flashed several different firmwares (official) with flashtool (wiping everything) - all the newest firmwares.
- *#*#72786#*#* in dialer to wipe carrier settings
- *#*#4636#*#* in dialer to go into phone settings and changing those settings randomly
- flashed another AOSP based custom ROM instead of stock sony
- wiping and formatting everything between the flashes of course
- cleaning and re-inserting SIM card (which i never took out before anyway)
But unfortunately nothing worked. Phone keeps to not recognizing the SIM card (which is working just fine in another phone). Everything else works just fine on the phone. The IMEI is displaying correct. I'm almost certain that the fault isn't hardware-based (i didn't drop the phone or exposed in water etc.) but software-based. Did i just managed to brick my phone by flashing something related to the modem which i'm not aware of?
I can't find any solutions on google, which help me, which is why i'm posting it here. Sorry for the long post.
Did anyone experience such an error and/or knows what else i could try to fix this? I hope for answers
Thanks in advance!
Anyone?
I've got the same problem.
I didn't unlock the bootloader or anything prior to getting the bug.
I wanted to downgrade to nougat, because aparently it helped someone in the forum below, but I didn't manage to do it.
https:// de.ifixit. com/Antworten/Ansehen/468864/Sim+Card+not+picking+up+mobile+network.+Possible+software+issue+(Oreo)
Did you try nougat, when flashing different firmwares?
Your post makes me question if its worth it, trying to downgrade.
Try to remove sd card if you have one. then restart the phone and see if sim card is recognized.
I had the same problem and I think it was a hardware failure in the end.
I also tried almost all the things you were writing above. In my phone it started slowly. Sometimes the SIM was detected but after some time the connection was lost.
It happened some time after I installed a new battery.
But since there are no original batteries available for the device anymore and the new battery was even worse than the 5 year old original battery, I gave up investigating the SIM issue and don't use the phone any longer.
I bought a new (used) x compact because I still like the size and I saw some development was going on for this device.
In the end I cannot tell whether the SIM was not detected because I broke something while changing the battery or due to age of the phone but I think it was a "normal" failure.
I also read from others that they had the problem and the SIM was working for some time after I switched the battery before it stopped working.
Nevertheless. Good Luck to you. Maybe it is something different on your phone.
