what are the extra charges for, actual phone calls or data usage?...or is this some kind of international travel "plan" daily fee that is automatically kicking in?...if it's an optional extra travel plan, can't you choose to not have it activate automatically when travelling?

for emergencies/safety, we always allow our phones to cellular roam for calls/text, but mostly only use our provider's (Xfinity/Verizon) wifi calling for non-emergency calls/texts to the US...don't use airplane mode, but we also NEVER allow data roaming...and we don't ever sign up for any kind of special travel plan...never get any unexpected mobile charges...yearly travel to caribbean and europe
