Does Signal allow multiple accounts on one phone?
No. Signal can only be registered to one phone number per mobile device. With a dual SIM phone, you must choose one number to register with Signal.
How does Signal messaging work with dual SIM phones?
Just as if there was a single SIM, Signal communication is available with the Signal registered number.
- All Signal-to-Signal communication is private and end-to-end encrypted.
- Signal can use whichever internet connection is enabled on your phone, WiFi or mobile data from either SIM.
Here's how to manage dual SIM:
