Lost iPhone trying to set up another phone.
Hi - one of my family lost their phone in NZ. I’m back here in Australia trying to set up a new phone for them using ICloud for when they return. I can get as far as 2 factor authentication ( after putting in Apple ID and PW) but since the other phone is lost it needs to be sent to a trusted number for recovery. That trusted number is not being accepted? Is there any other option? Thanks.
