Dual SIM always on not working.When I turn it on,it gives a message : updating settings~Sim card 1 failed and sim card 2 failed. Has anyone experienced this problem? Any help would be appreciated.

-kindly ensure SIM cards are working fine with other phones

-reset the APN / head to settings → mobile network → Access Point Names (APN) → Reset the APN

-restart the phone

-select a mobile network when prompted 

thanks 😉

Hello,

I have the same problem. Resetting the APN did not solve the problem. Stil I am not able to switch on "Dual SiM always on". The SIM 2 failed. It would be very useful if anyone can help me (us), because I see that there are many people with the same problem.
