United States travel eSIM comparison
If you need a US number for callbacks, compare a local prepaid line with a data-only travel pack. T-Mobile’s Prepaid eSIM app supports visitor plans with calls and texts, but activation must take place in the US. Arrange airport Wi-Fi or another connection for that setup step.

What matters here
- T-Mobile requires an unlocked, compatible device and an existing data connection for setup.
- Check whether the US pack separately includes Canada or Mexico if the trip continues there.
- Download national-park maps and booking details before leaving reliable Wi-Fi.

FAQs
Will a data eSIM receive texts sent to my Hong Kong number?
It does not move that number onto the travel line. Ask your Hong Kong carrier about receiving SMS in the US and keep the correct line active if needed. A US business may also require a US number rather than accepting +852.
Can I depend on mobile data inside national parks?
Plan for gaps. The National Park Service describes Yellowstone service as extremely limited. Check the particular park’s visitor guidance and save routes offline; a nationwide coverage claim is not a route-level guarantee.
