A relative travels a lot and we've been talking about putting him onto a VoIP option so phone works overseas provided he has wifi locally.
For him this means less number swapping (though he'll probably still have to sim swap for mobile data in some spots).
Would appreciate experience from others on -
1. Can you port an existing mobile (02x) to a VoIP provider?
2. Should he expect issues connecting to NZ VoIP from overseas?
3. Recommendations / tips?
