I have a Moto g5 plus RW phone and my wife has an old at&t flip phone. We are traveling to the Netherlands. If we get separated, will I be able to call her phone?
If you’re on WiFi and her AT&T phone has access to the local towers with her US number, then you will be able to call her.
If she has no International coverage, no one will be able to call her.
if you are not on WiFi, you will not have access to local towers when your SIM is installed. (But you can get a local SIM to work on those towers.)
Basically Republic has no International Coverage or International service
