no service

Hello everybody, i have one more interesting problem: my pro5 has no signal. When i try to choose preffered network manually or automatically, it says “cant connect this network, please try again later”. Did any one have experienced something like this?

Last question: did anyone try to send the phone to repair to the china? Because of the import and export issues, i can send it easilly but the phone cannot enter. Its only allowed with a passenger :\

Thanks in advance

by the way, i have new sim card and tried the ##4636## hidden menu setting preffered network but its just “gsm only”, i cant change it. Every time i choose others, its keeps turning back to gsm only :\

It has just fixed by itself :\

Looks like your connection to Meizufans was lost, please wait while we try to reconnect.
