[Q] Not Recognising Sim Card, Any FIx? - Galaxy Tab 2 Q&A, Help & Troubleshooting

Hi All
I have a Galaxy Tab 2 7" Model GT-P3100 I have not used it very much as I mostly use my S3. I bought it from Hong Kong, when it was tested in the shop in HK there was no issue with anything, all worked fine. I have since brought it back to England, mostly used it on wi-fi at home, then recently I decided to get a sim card to put in it to use it out and about.
When I put the sim card in, it comes up with a message box "SIM card added - Restart your device to access the mobile network - Restart" so I click restart and wait for the reload. But it doesn't recognise the sim card and still has "No SIM - Insert SIM card" within the notifications box as ongoing.
Now if I remove the sim card from the device while it is still on, it comes with a message box "SIM card removed - The mobile network will be unavailable until you restart with a valid SIM card inserted - Restart"
This sim card I am using has been tested in other phones and it works no problem, it is a pay monthly contract with Orange. I have also tried other SIM cards in this device and have the same response from every one.
So after doing some reading online and on this forum, I rooted the Tab and then used GalaxSim Unlock to unlock the phone, thinking it may be becasue I bought it in Hong Kong, the Tab is now unlocked but still shows the symptoms above.
Is there anything else I can do to get it to recognise the SIM or do I need to unroot it and send it back to Samsung?
Any help is gratefully received.

flash a custom rom ( stable is cm10.1.2) or a customised stock rom.I thinks it will fix your prob

It is not a ROM related problem.
Go to your network operator and have your old sim card replaced with the new one (with the same number if you want). Sometimes, an old sim card just don't work with newer service. G' luck..

Thanks to you both, the sim card is new, only 2 months old. I have just flashed CM10.1.2 and not only does it not recognise the sim card, I also can't do anything as the android keyboard crashes all the time.
I am going to try to reboot with the latest nightly to see if that helps.

I am now running the latest CM 10.2 from 21.8
The SIM is still not recognised and now my PC is not recognising the Tab either.
When I first plugged it in it came up with installing drivers for Google Galaxy Nexus?? Is this normal

Hi this is the same problem I have on mine,I am starting to think it is the card reader that is the problem ? which wont be a easy job to replace for me

Might be hardware problem
use triangle away to wipe binary on downloadmode then install a stock rom and contact service center to repair it under warranty (if your device have warranty)

Just flash a different modem

Problem with SIM card recognition

I have just bought a new HTC Touch Pro, but when I inserted the SIM card, it wasn't recognised. The phone shows "No SIM". My SIM works fine on my old XDA IIi. I tried a spare old SIM card on the Touch Pro and it worked (so I did insert my SIM right).
I restarted the phone, removed the SIM card and inserted it again and again but no luck !
I noticed that the old SIM which worked with TP has a bigger yellow part (the active part whatever it's called). I don't know if this is related to the problem.
Please help !
Anyone? Please help
Solved!!
Hi, buddy!
I have a samsung captivate and I was having the same trouble.
I'm brazilian and my sister send me the phone unlocked from US.
It had been working well for 5 months.
When I changed the SIM it has began asking me for the code(??!). It was programed for not asking PIN code so I got surprised. I typed my code several times until get the phone locked.
I spent more than 2 weeks to find the solution: Galaxy S Unlock, a free program available at the Market. It's necessary to root and install Busy Box (I installed mine with Titanium Backup).
Try something close to this for your device!
I hope this can be usefull!

G2X won't recognize SIM card

Anyone else experience issues with swapping their SIM from their old phone into the G2X? I have reseated mine from my N1 into the phone 3 times, and each time I boot it says I have no SIM card. Pulling my hair out!
I went from an N1 to the g2x and i had the same problem so here is the deal...
the g2x is a 4g phone and it required a new sim card version so i had to trade in the sim card that i have had since my i got my razr in 2005...
so disclaimer to anyone who buys the phone outright, you have to have an updated sim card... just go into tmobile and they will give you one...
mines wont check for sim card at all it keep saying no service even without a sim card it usually say no sim but it just say no service can someone help plz plz plz
Fyi make sure it is a corporate store. Otherwise it could cost ya $20. Customer care might even be able to mail you one...not sure. If your near Chicago I would just give you one of my extras.

I reused the sim from my N1 and have had no issues but it was probably a newer version sim since I just got it beginning of last year.
If you have an old T-Mobile phone lying around, try inserting your SIM into that, and using it, then re-insert it into your G2X.
Alright I opened it up and it looked like the antenna cable was a bit frayed near the tip, I attached a few pics. It was connected though so not sure :/

I have the same issue.
Mint condition G2X does not detect my sim card reads "error while trying to connect to network"
I am running CM 7.2 I have wiped everything and reflashed still no luck.
Add one more to the pile...
I also recently began having this problem, but my device previously worked fine.
I have tried Restoring to Factory V21Y with Mar 11 Baseband
Flasing a GB Based ROM & Stock Kernel
Flashing CM9
Flashing CM10
Entering *#*#INFO#*#* Phone Info and modifying frequency band (No Go).
At one point I was able to read the Phone # from the SIM card, but couldn't get a lock on Netowkr. I can visually detect T-Mobile and ATT in Mobile Networks.
I have tried this with 4G Enabled SIM Cards and older T-Mobile SIM Cards.
I have tried Simple Mobile, Straight Talk, & ATT SIM Cards.
I have tried using None APN's, the TMo/Simple Default APN's, and Modified APN's for Straight Talk & Family Talk.
No avail.
Any ideas?
I had the same problem. A new SIM card fixed it.

I gave my friend my old G2x because she was switching from AT&T to TMobile. She went to the TMobile store and got a new SIM card and her old AT&T number transferred to it. It works on her old iPhone but when I insert the SIM card on the LG G2x , it keeps saying 'no SIM card inserted'....do i need to flash a certain baseband on it and/or setup a custom APN for it? I am on the stock ROM thats rooted...
Any help is much appreciateed
Sorry for not replying until now but I rarely visit here anymore. My G2X had a bad Sim card which a new Sim fixed. I just had to wait until the network could authorize with it.

Try to insert the sim card with the tablet on. Does it restart? If not are you sure you are inserting it with the correct side?
Hello, thanks for the answer, I tried all that already, anyway the Sim only fit in one position so you cannot take wrong.
The tab restarts when inserting card yes.
I tried also taking the battery out for 10 mins... Clean the head of the Sim compartment but no luck.

Just removed the back by pushing under the sd card slot then inserted a flat tool to unclip the lid, then removed the batery connector.
However i still have the issue, its driving me crazy as it is my working tool...
does the original SIM still work in it?
perhaps try flashing original & latest frimware updates for new/different modem.
I know one chinese version of tab plus has locked bootloaded dud to China's restrictions, I would not be surprised if they have locked down modem as well.
And for the heck of it you could always try Galaxy S Unlock app, to be certain you're unlocked.
Strongly suggest backing up /EFS folder (twice) just in case.
Thanks for the suggestion, I flashed the device twice already but there is only one file. Could you direct me to the files you are referring to please I'll take a look when I'm back home, thanks again.

I would try EVERYTHING else before flashing a new modem. Toggle airplane mode. disable/enable packet data, etc.
First, does the original SIM still work?
If so I would give the Galaxy S Unlock a shot for the heck of it.
These other SIMs have you tried them in other devices to either make sure they work or activate them?
did you purchase device on a SIM contract??
sim issue
The original sim does work, i have put it in other phones and it works fine, i have also tried other sim but still same issue, message still say "please insert sim card"
I have purchased the tab sim free in hk so no, no contract, it did work fine since december until 2 days ago where i input a data only sim card, when i insert sim card it does reboot, meaning it detects the card in the socket but thats it.
Concerning Galaxy S Unlock my tab is not rooted i have used only legit firmware until now so im not sure about that.
PS: looking at my phone servie status it says:
Service State: Out of service
Are you sure you havent been sold a bad or expired sim card?
Id try to give samsung customer support a call at least, they will probably tell you to send it to them anyway.
Can you try exchanging this for another one where you puchased it?
Well, i bought it during my holidays in hk but i live in norway, so... bit difficult to chage it, the sim card works just fine in other devices so it should work in tab.
I tried the galaxy s unlock and during step 1 it says error for efs backup, so either because im not rooted or because my efs is corrupted.
Probably because youre not rooted.
Im wondering if the SIM could be from a small provider which isnt recognized by the device?
It should at least dected then say something like network provider unrecognized, etc.
I really dont what to say.
I would keep trying other sims, try to get a 5$ pre pay from a major carrier like O2, 3, tmobile, etc. not sure what carriers you have over there.
Well i use Telenor which is the biggest and also quite big in europe, i will call customer service tomorrow and hear what they say, but i fear its gonna rip my pockets...

did you push the simcard all the way to the bottom of the slot?
I need a pen to push it....so I wonder if you insert your sim card properly.

yes, since the first time, repair shop said they cannot help since device has been purchased in hong kong...
No solutions until today...
Solved
After dismantling the tab completely (hard work guys...) i confirm that the sim card reader is defect, the cushions that reads the card did not press completely on it so i applied a temporary fix by adding an extra layer to thicken the card so it can press correctly on the cushions. I did try this fix before with the tablet in one piece, however i could not get it to work correctly.
Anyway thanks for your help and i'm happy that i can use it again

SIM Card not recognized - I need help

Please, I need help.
I just bought a Galaxy Tab 7.7 used, and i tested when I went purchase with another boy, and everything was ok, SIM Card normal functioning.
Once I got home, the SIM card does not work anymore, it does not recognize the SIM card and recognizes no other.
Has no 3G network anymore.
Please, is there anything I can do?
ROM Stock 4.0.4
Check there is no obstruction in the SIM card slot and clean.
If you haven't done anything to the device, I'd return it if possible. The seller should be reasonable about it.
