Forward calls between your SIMs
Forward your calls between your SIMs using Smart dual SIM – 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.
Dual SIM is not supported by all phones. For availability, go to www.microsoft.com/mobile/
You must have both SIMs inserted to change the dual SIM call settings.
For availability of this service, contact your network service provider.
