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.
