So the phone seems to get service then within 2 days more or less will stop getting service. Some-times stop getting service quicker. Ive removed the main board and put into a new casing and still have the same issue. Its not blacklisted. So is there a main board level problem i can try to fix? or have fixed?
Have you tried to reset the network settings. Settings>General>Reset>Reset Network Settings.
