Hi there, I have purchased my tab last friday, played around with it during the weekend (root, overclock, etc.) Everything was fine - internet connection via 3G and WiFi, battery life and so on. However after I swithed off my tab on sunday evening and left it on charger, monday morning I realised that galaxy tab 10.1 does not recognise any SIM cards. The device itself is unlocked here, in Lithuania.
Any ideas what might have caused this strange behaviour? Everything else is working fine.
Hi!
I have the same problem, started about a week ago. SIM-card just looses connection at random times. Mostly when i've just left it in the charger for an hour or two.
A reboot is needed then it's working as normal.
What do you think? Should i return it?
Did you try and setup the APN manually?

Obviously...
The thing is that device itself does not recognise SIM card. Once You try to configure APN manually, it sais "please insert SIM card" :-(
and reboot doesnot help...
I have this issue too! I thought i was the only one experiencing this.
I have this problem 1 time, but i tried to switch sim with the one in my phone and it worked. Afther i switched back again and still working.
I got the problem afther my tab have been switch off for 5 days.

Well, after I left device in one of authorised dealers, they acknowledged the problem and offered to replace this Tab. So it turns out, one can only hope, that it does not happen to him...
Hi guys
Turns out all my problems were caused by overclock kernel. Today my tab was replaced so first thing I did was root it again and make a back up. Then I installed OC zip file from SD card via CWM recovery. Guess what? Device did not recognise SIM card again... luckily I had a back up ROM. After I went back to the original ROM everything was OK.
So be careful before over locking your tabs.

my 10.1 tablet says please insert sim card after i have inserted the sim card is it possible..i bought it in hong kong and now am in africa...its kh5
my friends is kg7 and it works fine cud it b a software issue or hardware
same problem just happened to me.
is there any solution found?
sim is ok on my htc desire but tab 10.1 cant detect it.
it has stop suddenly while browsing some news sites.
reboot does not help
i tried with another SIM also, same problem - cant detect SIM card at all,
when trying to open Mobile Network it says - Please insert SIM Card or something simllar.
Also i found that in About Phone - Status, IMEI and IMEI SV are Unknown, Serial is OK, is this normal?
Look I know this is a dumb question, but have you rebooting the tab after inserting the Sim? A client of mine had the same issue and we struggled for days until we realized we hasn't tried that. Sure enough that was the issue.
I think the tab only tries to access the Sim card on bootup.
Sorry if you have already tried this.

I have the same problem. Tab says "plz insert sim card. I have already inserted sim card
Same issue here .. I picked up the tab on a business trip in India and it worked fine while I was in India . I came back to UK and tried a UK SIM and it does not recognize a Vodafone Sim , Giff Gaff but recognizes 3 . Even though it recognizes 3 it does not let it register on network.
Not really sure what the issue is .. Is it restricted in some way .. ?

>> about device
>>status
M Phone number is showing as 000000000000
any ideas how to change this?
I think it's carrier dependant, can u tell us on what network you are? I'm not 100% sure though
all the s3's I've seen don't show it in Lebanon
I'm on t-mobile uk which is now showing as ee, (everything everywhere)
its a SIM card thing I put my SIM in wife's old iPhone and now on gs3 shows number

Yes it's written on SIM card, some roms can't write it down on the card, the solution if you absolutely want this is to put your card in an old/another phone.
With my previous phone the number wasn't readable, now I have it.
Thanks for the replies, its not that important, but i may swap the sim over sometime .....
thanks
Hi

Same thing happened to me a couple weeks ago, now it wont read the sim at all. I ordered a new sim tray but it has not arrived yet, but if you search other threads, this may not fix our issue. Seems to be a problem with this phone.. I'll keep you posted if the replacement fixes my issue.
Dunno. Might be a fault in the mobo or the sim slot. I replaced the sim slot and it went away for the most part, but it comes back at least once per day.

Hello
My SGS3 gti9300 is not detecting my SIM card, it was fine this morning, i used my mobile data without any problem but as soon as i switched my mobile data off, my phone lost network. It tried pulling off the SIM card and putting it back in but in vain; my phone would read the SIM card, it says 'No service'. I also tried checking my IMEI number by *#06# on the dial pad, it would display 'null / null'. I do not have any other micro SIM card right now to try in my phone. My current SIM card works fine on other phones...so i guess the problem is in my phone
Besides, later when i played music on my phone, the music would stumble and at times the track changes by itself. That problem came along with the SIM card one.
My phone is not and was never rooted. It runs on Jelly Bean.
Please help me fix at least the SIM card issue :crying:
If your phone is fully stock and never rooted then return to Samsung for warranty repair.

It's look like a problem with efs. Search on forum how to recover efs files.
Just when it went out if warranty, I keep getting this pop up and need top keep restarting the phone. I have the Tmo version with everything stock.
Even changed it new sim card an still no fix. Am I doomed?
Anyone? Please help...
