Hi guys, so I just got a dell venue3840 hspa+ yesterday for my mother. But after I change sim card, the tablet totally lose mobile signal and I tried many ways I found by the internet.
Cause I lose it by change the sim card, I don't think it is the hardware problem.
Today I will try to flash dell stock rom hopefully can get mobile signal back.
If you have any suggestion please help me, the wifi work well but sometimes I need the 3g outside
