United States travel eSIM comparison
US eSIMs host on AT&T, T-Mobile or Verizon. T-Mobile-hosted plans usually win big-city mid-band 5G, Verizon dominates interstate highways, AT&T splits the difference. Data-only as everywhere — your HK number keeps working over IP calling.
Cheapest right now: Nomad Global · 5GB · 30 days at HK$188 per month.
What matters here
- T-Mobile-hosted = fastest city 5G; Verizon = best highway coverage
- National parks have big dead zones on every network
- No US number needed — apps verify by SMS to your HK SIM

FAQs
Will I get a US phone number?
No — travel eSIMs are data-only. Restaurant waitlists and hotel bookings that insist on SMS go to your HK number over roaming, or use the venue's web/app check-in.
Does it work in national parks?
At park entrances and visitor centers usually yes; deep into Yosemite, Yellowstone or Grand Canyon backcountry, every carrier drops out. Download offline maps and tickets beforehand.
