Hello,
Please help, I have Gionee s6s. I turned off one sim from setting menu and when I turned it on it only working one sim at a time. Please resolve this issue.
I just found a solution. I don't have Gionee S6 but my friend has one.
Follow steps in order:
1> Reboot the phone .(by holding power button and tapping on Reboot)
2> When phone shut down and again power on , You will see Gionee Logo Flash Screen. At that moment hold the lower Volume button
3> You will be redirected to Factory reset mode.
4> You can move down the cursor using Volume down key only.... Try to highlight the "Start Test"
5> Once you highlight the "Start Test", Press the power button and your test will be start.
6> Allow the phone to complete all test...
7> Ignore the Failed test
8> Now reboot the phone
Congrats you will see Both Sim is working perfectly....!
Please let me know if you find any difficulty in above step.
Since I do not remember how the phone settings look (interface), I can only say in words. Go into the settings of the SIM card and put permission so that they work in parallel
The permission option doesn't allow to make both sim work in parallel. Once you have active one sim... other sim is closed. Another way, if you turn off the active sim and turn on the other sim, then you can't turn on the first sim again.
This is the problem faced in Gionee....
Please read my answer and you will solve the problem
