AT&T Passport is an add-on available for postpaid AT&T subscribers and gives you international coverage for a period of 30 days.

AT&T Passport includes the following features:

• Unlimited international texting
• $0.35 per minute of international calling
• 2GB of high-speed data, then billed for overages at $30 per GB
• No hotspot support
• $70 per line per 30-day period

AT&T also offers a $140 Passport plan with 6GB of data instead of 2GB.

You can schedule the AT&T Passport to activate on a desired date and be canceled at a desired data, even across billing cycles.

You can also choose to do a one-time payment, or to have the AT&T Passport automatically renew.

AT&T Passport works in 230+ supported countries.

To be quite frank, this add-on is astronomically expensive. You are much better off getting an international eSIM plan, or signing up for a carrier local to the country you are visiting.

Or, if you are traveling for a shorter duration of time, you may consider AT&T’s International Day Pass.
