Have you done anything to your phone since the last time it worked? Any updates? Did you flash your rom/radio? If you tested it on someone else's phone and it didn't work there either I'd say it's your sim card. Try in a 3rd phone just to be sure, but I'd consider taking it to your Cell provider to get the sim card checked out.
Call your carrier.
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

Hi, I have the UK 4G galaxy tab 3 8.0. I've been using a Three network voice/text/data sim in it for a few months, till I tried to go on the the browser and it said 'Your Sim Will Only Work in Your Phone'. Tried everything I could think of to get it to work. I called the network explained that my tab was a phone because I've been making calls off of it. They was having none of it and said my sim will no longer work for data inside my tab....killer!! It's my only source of internet and I haven't got another device to use it with. I was thinking possibly if I root it, there may be a utility which allows me to change what my tab is seen as. For example change it so it's recognised as a phone and then my sim will start working again. It's never going to work again as it is at the moment. I've rooted it before and didn't really want to do it again, because it kept screwing my data connection, I unrooted and it's been fine for weeks. Please someone help! If I have missed any details, sorry.
P.s the tab came from Vodafone UK with a sim contract that is not being used anymore, I bought the tab near enough brand new but still pre-owned.
Thanks anyway
Oh Dear, what have I done?
I have an old galaxy note 2 that I am trying to set up with a new sim card for my boss. I have an unlock code from three mobile, the new EE sim card and have followed the unlock instructions from Three Mobile. New card went in, turned phone on in readiness for what they described as "The handset will display an empty text field and request the 'SIM network unlock PIN", but the phone never got passed the first bit of booting up, just displaying "Samsung Galaxy Note 2" in whit writing on a black background.
I have tried: putting old sim back in, turning it on with no sim, doing a hard reset with no sim, old sim, new sim and any conceivable option or variant, but in all cases seems to end up at the same screen. To add insult to injury, the bosses old has now transferred onto the new sim/contract, so he is without a phone and I'm going to start looking for a new job...
How bad is this? Any suggestions would be very much appreciated!

Hi,
I see you've already asked about this in the appropriate section. Since XDA Assist is here to help navigate the site, not for support.... I will close this thread.
Thanks!

First of all i am certainly no expert but this might help. From the way i understand it the sim is for LTE and you would have voice and 3G if no sim existed. When you unlocked it
you allowed the phone to go international. How ever if the sim card that is in the phone is a US sim it will not work out side US. Since you said that you are in Venezuela right now
and did not say where you purchased the phone can i assume that you might have a US sim in it. That being said pull the sim out and see if the phone will now give you 3G.
If it does then get a new sim from where you are.
it wouldnt be cdma at all, just gsm, and your data issue is likely all due to the APN settings. Sounds like youre international unlocked, which is good, but your apn settings are likely messed up. I see that you are rooted, but are you on the stock ROM?
still no solution for DATA on gsm device
