[q] not registered on network topic

Hi all,

I bought a Samsung galaxy note 3 in Malta about 9 months ago...and worked perfectly. I travelled to Scotland a week ago....and the network registered successfully there too. BUT when I try to make a call send a message it tells me again the "Not Registered to Network".....the signal is full and the R (Roaming is appearing). Phoning the mobile network company it tells me that from there side everything is ok. Putting the simcard in another mobile it works infact.

I tried also to put a simcard from Scotland into the mobile to try if it will work. The "Not Registered to Network" does not pop out BUT it always tells you "Call ends" as soon as you press the call button....so practically same situation.


Please help. I am really frustrated!


Thanks
