Which network does USA eSIM use? +
Most USA travel eSIM plans use T-Mobile's network, which has the largest 5G footprint in the country — covering 99% of the US population. Some plans use AT&T for broader rural coverage.
Can I use the USA eSIM in Canada too? +
USA-only plans don't cover Canada. For cross-border travel, look for a North America bundle covering USA, Canada, and Mexico. These typically cost $5-10 more but save you buying separate plans.
Does USA eSIM work at airports? +
Yes, absolutely. All major US airports (JFK, LAX, ORD, MIA, SFO) have excellent T-Mobile/AT&T coverage. You'll be connected the moment you clear customs — no need to queue for a SIM card.
Does USA eSIM work in national parks? +
Coverage in national parks varies. Popular parks near cities (Yosemite, Grand Canyon South Rim, Zion) have decent T-Mobile coverage. Remote backcountry areas and deep canyon trails typically have no signal from any carrier.
Can I use eSIM and keep my home number? +
Yes. Your home SIM stays active for receiving calls and texts. The eSIM provides data-only internet access. Dual SIM means both work simultaneously — you can receive calls from home while browsing on US data.
Is there a better option than eSIM for long stays? +
For stays longer than 30 days, a US prepaid SIM (T-Mobile, Mint Mobile) may be cheaper. For travel under 30 days, a travel eSIM is more convenient — no ID required, instant activation, and data-only plans start from $12.
