Hello! We bought iPhone with 2 SIM cards. One is Russian and one is French. The question is the following - how can we use it:
When we choose Russian sim as the main - all outgoing calls should be made from it. Doesn't matter, which SIM was used before ?
Here are a few of the many ways you can use Dual SIM:
With iOS 13, both of your phone numbers can make and receive voice and FaceTime calls and send and receive messages using iMessage SMS and MMS.* Your iPhone can use one cellular data network at a time.
* This uses Dual SIM Dual Standby (DSDS) technology, which means that both SIMs can make and receive calls.
