When carrier roaming is better

Choose T-Mobile roaming if your eligible plan already includes enough data and texting for the trip.

When a travel eSIM is better

Choose a travel eSIM if you need more high-speed data, hotspot, or a dedicated plan for a specific country.

Check included benefits first

T-Mobile plan benefits vary by plan and destination, so confirm the included high-speed data, basic data speed, calls, and texting before deciding.

Use a travel eSIM for heavier data

For maps, social video, uploads, hotspot, and remote work, compare prepaid plans with enough data and validity for the full trip.
