Forward calls between your 2 SIMs

Get the most out of your 2 SIM cards. If you forward your calls between your SIMs, when someone calls you on one SIM while you’re having a call on the other, you can manage your calls from both SIMs just like with only one SIM.

Make sure you have 2 SIM cards inserted in your phone.

Select Menu > > Connectivity > Dual SIM > SIM numbers.
Type in the numbers of your both SIMs and select Save.
Scroll up to Forward calls, and select Between two SIMs, From SIM1 to SIM2, or From SIM2 to SIM1.
