[Q] DUAL SIM Problem - Lenovo S750 MTK6589
I've checked forum to find a solution for my problem, but whitout succes.
Now I using LENOVO S750 Dual SIM, with standard Android 4.2.1.
SIM1(3G) - just data for the internet, skype, VoIP, etc.
SIM2(2G) - just voice calls and text.
My problem is like that:
When I'm using my phone for internet (skype, YT, data exchange) nobody can call to me on second SIM2 card number (it says out of range or phone switch off) even I have full range on both signal indicator's (3G not important but 2G is 100% range).
When I turn off the data on the SIM1 or turn on WiFI to use internet on the phone everything is OK (voice phone number on SIM2 works perfectly)
I try to change lot of settings but the problem still exist, It looks like I don't have active SIM2 card while SIM1 makes data exchange.
When I make normal phone call by SIM2, data exchange on SIM1 is switching off.
Before I do not remember that kind of problem on my phone.
Please anyone knows a solution for this??
And sorry for my english
- when I turn off automatic data synchronization( settings, data use, auto sync.) everything works perfectlty, but the Gmail and any other online apps, need hand made sync, so it's just a partial soultion, any suggest??
Why data on SIM1 turn's off the SIM2 voice service??
