> a friend in Greece roaming with a Canadian Rogers SIM card was unable to use her phone I've heard this from several individuals. It makes sense: Rogers, being totally dark, couldn't authenticate any roaming sessions. I wonder how fast a roaming provider boots you off their network though. Roaming usually tunnels your traffic to your home provider, so I could see data halting immediately. Maybe local calls work for a while. This effect sunk in when they said they couldn't receive any SMS 2FA. Even people with a local SIM SIM setup (highly recommended!) still need to slide in their home SIM to log into some things.
