Help Problem with network

[JovcicN]

I bought S3,its made for asian market but decoded or whatever for europian market,now i have a problem with it losing a network. It works for like 1 day then networks breaks and its not getting it back untill i pull battery out while phone is on and when i turn it on again it works again for like 24h. I read a few threads and i see people mention SIM Toolkit and its there on ALL apps tab but its showing 0B for everything for SIM Toolkit. Any1 got idea how to fix it? Tnx in advance.

Instead of a battery pull, does turning "flight mode" on then off fix it?

Are you losing your imei when this happens?

Didnt try it with flight mode thing,ill wait till it happen again then.
IMEI is still there when it losses network,he does show signal and everything but call/sms/internet aint working.
