Activate MultiSIM on up to four additional smartphones and use the same phone number for all of them. This means you can make outbound calls with those phones,
but anyone calling or texting you can only reach you on one device. If you’d like to change the device you’re reachable on, activate your new main device for incoming calls with a GSM code.
These are the GSM codes for receiving incoming calls:
To activate a phone directly: *100# and press the call key
To activate a phone remotely: *100*phone number# and press the call key
To find out which phone is active: *101# and press the call key
To find out the number of the phone: *103# and press the call key
