Hi. I recently bought a Zenfone 10 and was really surprised to find there is no Backup calling option given it's a dual-SIM phone. ie, if SIM 1 is unable to make a VoLTE phone call, it uses VoWIFI over SIM 2's LTE data connection. This has been a standard feature in Pixels, Samsungs and iPhones for a number of years now. Any sign of it coming to ZenFone?
