[Q] Keeps saying simcard not detected.

I have a rooted T-Mobile G2, and a Fido Sim Card. I got the phone unlocked and got my Fido Sim card working. Now, after a year, from time to time, the phone would just suddenly not recognize that there is a sim card in it, and give me the No Sim Card problem, and I get no service. Rebooting sometimes helps, sometimes doesn't.
Help?
THANKYOU!

Get a new SIM card?

It sounds like it might be an issue with your ROM. I had the same problem with CWM a few months back but it resolved itself after a few updates. Search the CWM nightly thread for 'insert sdcard' if you're curious.
If your phone, a pc or other device cannot recognize it, then its probably a dead sdcard.

SIM, not SD.

network or sim card error?

So I found out that my phone number shows up as "blocked" when calling people and tried to fix it via Call Settings - but when I try to go into the "advanced settings" menu, I get a "Network or SIM Card error" and I don't know what to do about it? I tried taking the SIM card out of the phone and doing it again - still got the same error. I do have my phone rooted and the Ultimatum ROM installed, could that be causing the issue?

Check with the developer and see if it is a known issue or if he can recreate the error himself, otherwise get a replacement SIM. (did you have this issue before putting this ROM on?)

I haven't tried it without the ROM on, but I'm going to flash the stock rom back on and see if that'll fix it, otherwise I'll hop over to the at&t store to get a new SIM card.

[Q] Insert Sim to Access Network Service.. IMEI Null

Hey Guys,
I have an AT&T Model SGH-1317 Note 2. For use on other networks, I unlocked the phone using the *#197328640# menu option. However, the phone failed to start the hot spot stating Mobile data was unavailable or Invalid Sim. However, I am able to tether perfectly using the same sim on an another S3 so I was sure its nothing to do with the sim or network operator settings.
I looked up and found XDA website with tons of information. I assumed my phone was locked by AT&T. Hence, I rooted the phone using CF-Auto-Root, backed up complete data using Titanium and using Rom Manager I installed the Crash Aroma 4.1.2 Rom. I wiped the data and cache 3 times as suggested. However, after the boot I am unable to connect to any mobile network. A Click on Mobile Network says "Insert Sim Card to Access Network Services". Dialling for IMEI number prompt a Null.
During Installation I noticed the Crash ROM has overwritten the Radio.. and I am assuming this is were the problem lies. but I leave it you experts.. Request Help!
Sunil.

What carrier are you using the device on?

Am currently on Du - A network in Dubai, UAE. I have been reading more forum information and some suggest that this may be related to the EFS folder getting corrupted which may cause the IMEI number to fail. Some suggest that there are software to rebuild this information by using the IMEI number behind the handset..
I also noted that my phone model has also changed to GT-7100 instead of SGH-1317, Wonder if the Crash ROM was apt?
Would you suggest installing a Jedi Rom specifically built for SGH-1317... or is the damage already done?

Back Online
Since I found no replies.. I had no choice but to give it to the Pros.. I handed my phone day to one of the Unlocking experts at a mobile store… He was confident that his technicians would resolve this. But after 2 Days, they have given up.. He suggested the phone would fetch me US$ 10 if someone used it as a demo unit at a mobile shop..
I was sure this was something to do with the Modem, IMEI and the all important NV folder. I was able to find a Stock ROM for the SGH-1317 and I also found a link at XDA about using EFS pro to change the IMEI.
Using Odin software, I flashed the phone with the stock rom. Unfortunately, there was one error when it tried to communicated on com1. Having no choice, I continued. Restarting got the AT&T style boot but it again froze on the Samsung screen. Dreading the communication error, I restarted several times with no results. Finally I realised if would be due to the cache and user data. I reset the phone to factor settings wiping out the user data and Whola.. The phone sprang back up..
Lessons learnt.. Backup your rom and data before playing with custom roms. Read Read Read and don’t flash in the middle of the night..
Since I am back online, I plan to stick to the stock and crappy 4.1.1 with all the AT&T dead weight. Will live without the ability to Tether until my fingers get warmer.. It won’t be long as I am already bit by the Custom Rom Devil..
Don't Give Up Easy..:good::victory:

Please I am having the very exact same issue and can't seem to have it fixed
Using CMW I also flashed it back to stock rom, didnt have any problem or errors doing it but im still getting No SIM Inserted. I have deleted cache and user data several times... Tried flashing CM10 and CrashRom see if they made a difference and still No Sim Inserted... tried 3 different kernels and still same issue

I have the exact same problem since yesterday. I've tried everything and anything to no avail. I'm very close to returning the phone.
I would really appreciate any input.

Same issue
I flashed crash rom 4.5, over the stock kernel and it gave me that same message. I've tried everything I could think of, which included everything in this thread to no avail... any further advice would be greatly appreciated.

Your username suggests that you have the N7100 device ??
If so. ..you are in the wrong place for support. ..As this is the SGH-I317 section.
If you are showing IMEI NULL with no baseband you may have to restore your backup image to correct the problem. .
If no backup image exists. ..you will need to flash a factory N7100 image from your section.
Look for the return to stock thread for your specific device and that should fix you up...
The CF AUTO ROOT files are device specific. ..so I hope you haven't damaged the partitions.
Good luck. ..g
Edit:
This will help. ..and will place you in the right section. ..
Just go to page 1...good

No cell network after flashing factory image

Hi,
I just flashed 4.3 google factory image, and everything went well.
When I switch on the phone, it ask me my PIN code, and then, no mobile network is recognized. The problem persists even after a reboot.
I tried with 2 sim card from 2 different carrier, and the result is the same. I'm in France, and the radio xxlj1 worked fine before the flashing of the factory image.
Does someone know what is going on?

I would try newer radios, if possible...

UGLL1 was not better than XXLJ1 before factory image flash. I don't think it is the radio, because it was working before very well with xxlj1.

I have just noticed that I can put a wrong PIN code and the phone can unlock the sim card. Is it possible that the sim card reader is dead? Is there any tool or app to check the readability of the sim card?

I mean it would be one thing if you dropped the phone in water or something... but for it to stop working after flashing the factory image?...
Try flashing the earliest available image, 4.0.4 I believe.

I tried it, without success. I flashed a factory image, because most of times, my phone was stuck at google logo without reason, even after a full wipe.
But now, I noticed that the phone can connect to cellphone network at approx 1 boot over 10. I suppose it is a hardware problem, but it is very strange. When the network is ok at boot, everything is fine until next reboot, when the SIM card is detected, but not read correctly.

[Q] No Signal after Stock Flash From Odin

Ok. I was on JediX20 not to long ago. I was having problems with my signal. It had completely no signal. I put the phone into download mode and reflashed the stock firmware through odin. It works like a charm except....when I boot the phone up with no sim card...it shows signal strength...but when i put my sim card in and turn it on...it gives me a no signal icon + no mobile network when i try to dial out. I thought it was my sim card and it had gave out so i talked to my phone rep and i switched to a brand new sim card. Same thing happen. The only reason I know its a software and not a hardware issue is because when i go to settings, back up and reset, and i go through everything to reset it. The icons for data and signal appear just before it cuts off. Im at a loss of what to do. Any Advice?? or a Thread someone could point me too?

IMEI or Baseband available?

Did you flash the correct firmware ?? (have to ask )..
And once your Odin flash was complete ...did you boot into recovery and wipe all data and caches ??
It sure sounds like you're running into an incorrect APN on boot...
As mentioned above ...does your phone show the correct information ??

I didnt wipe data and cache as soon as I flashed through odin. I did after the phone booted up. Maybe ill try that. Thanks.
