Users who have a device with dual SIM must choose one of them as their main SIM card, since they will use it to make outgoing calls with Infocaller App. If you want to change your SIM card, you can do it by adding and activating the phone number of the secondary SIM card in the 'Settings' section. To learn how to change your phone number and activate other numbers, go to the Help section titled 'Add or change a phone number'.
Attention: If you have configured the phone number of SIM1 as the main number in Infocaller App, you should select that SIM card when prompted in Call Out mode. Otherwise, infocaller will reject the call.
