| Provider | Data | Days | Approx price | Hotspot | Best for |
|---|---|---|---|---|---|
| Ubigi Value | 10 GB | 30 | US$14 | Yes | Clear price winner on fixed GB |
| Airalo | 10 GB | 30 | US$22.50 | Yes | Familiar app; T-Mobile common |
| Saily | 10 GB | 30 | US$22.99 | Yes | Similar pricing to Airalo; security extras |
| Nomad | 10 GB | 30 | US$25 | Yes | Also sells short unlimited (e.g. 10 days) |
| Holafly | Unlimited* | 30 | ~US$73.90 | Capped prepaid hotspot | Heavy phone use; AT&T / T-Mobile |
Quick take
Buy Ubigi 10 GB unless you know you’ll smash through data. Ubigi doesn’t always sell USA unlimited — heavy users should compare Nomad short unlimited or Holafly day packs instead.
FAQ
Is a travel eSIM cheaper than roaming?
Usually yes — a 10 GB travel eSIM typically costs a fraction of daily roaming passes from home carriers. Heavy users should still compare per-GB prices.
When should I install my travel eSIM?
Install it at home on Wi-Fi a day or two before you fly, but keep it switched off until you land, because many plans start their validity on first connection.
Is 'unlimited' eSIM data really unlimited?
Rarely. Most unlimited plans slow you down after a daily fair-use cap (often 1–5 GB/day) and limit hotspot use. Check the cap before you buy.
