[Q] Tab won't find sim card - Galaxy Tab 3 Q&A, Help & Troubleshooting

Hi All ,
I have a Galaxy Tab 3 7.0 I bought in China and tested with a sim card to make phone calls with the Chinese version of Android on it. The phone side worked no problems.
I have flashed the Tab to Android 4.4.2 Italian version but now it does not find the sim card.
Sim card is inserted the correct way and I can't see anything wrong.
Any ideas please.

Hi, so i upgraded my note 3 neo to 4.4.2 from 4.3 after the phone itself prompted me to do so, and i did this update automatically not manually by myself, i heard that update was being released and it did. However after i did the update and the phone restarted with the updated os KITKAT 4.4.2 . The phone is telling me that i need to insert a sim card, but the sim is already in. and my IMEI is null. i even tried with other sims and same thing. i can't make any calls send text messages nothing. And before update the phone worked fine it read the sim card .wifi works fine but its not reading sim cards now and IMEI is null. Its a brand new phone got it for christmas, never threw it down or anything. Can you please help me if you can? thank you

2 simple suggestions :
1. Check your new SIM card in some other phone.
2. Can be loose connection or slightly different fit.
Good Luck !
