2G/3G Problem

dlmg5353

Hi i 've used all versions of ROMs , my problem is that  i have random signal disconnections during the day simultaneously on both sim cards although phone shows full signal for sim 1 only( i mean i'm able to make only emergency calls like both sims are off). It seems a problem of auto switching between 2G/3G mode. Only if i select 2G only mode it seems to remain ok. It is a bit annoying because i'm losing calls.. Is there any solution for this? Thank you

you can use both sim cards but you can t use data simultaneously on sim1 with call on sim2.

if i remember well because i got same problem il you install a tierce party soft for entering in engineer mode you can choose priority to data or priority to calls but you will continue to loose data connections when calls from sim2 activated

Dear user,

Your case is a typical symptom if only one of the two GSM antenna connectors doesn't connect to the motherboard/bottom PCB properly. Your phone should be disassembled to check the antenna connections. The 2G connection needs a lower reception level, so your phone even can work without a working antenna.
If you haven't changed anything in the EngineerMode, the mobile data priority option cannot be an issue.
