Managing what number to use for calls, messages, data, voice and apps
If you're using two SIMs you can set up which SIM your phone should use for:
- making and receiving calls
- voice features
To choose what lines/numbers are used for calls, go to Settings > Mobile Data > Default Voice Line / Mobile Data.
The phone will warn you if you attempt to make a call from the “non-preferred” SIM.
You cannot have 2 active calls at the same time, for example if you were on the phone and received a call to your other number, that incoming call would go to voicemail.
You can set calls to be forwarded from one line to another.
Data, voice and messages
To choose what SIMs and phone plans are used by default for data, voice and messages go to Settings > Connections > SIM card manager.
“Dual Messenger” can create a duplicate application for each number, for messaging applications like Skype or WhatsApp. The option can be found in Settings > Advanced features > Dual messenger.
