Hawaii & USA Travel eSIM Comparison 2026
Choosing an eSIM for a US trip usually comes down to three providers: Airalo, Holafly, and manaMOBILE. They all sell data-only eSIMs that install before you fly and connect when you land. The differences are price, the network they use, and what happens when something goes wrong. Here is the honest comparison.
At a Glance
| Provider | Typical price | Network | Support |
|---|---|---|---|
| manaMOBILE | $9 for 3GB / 7 days | T-Mobile 5G | Human support from Hawaii |
| Airalo | $6–9 for 1GB only | Varies | Chatbot first |
| Holafly | $19–59 "unlimited" | Often throttled | Chat + email |
Price per Gigabyte
manaMOBILE is about $3.00 per GB on the 3GB plan. Airalo lands around $6–9 per GB on its smallest plans, and Holafly's "unlimited" plans cost $19–59 and are throttled after a daily cap. For a one- to two-week trip, manaMOBILE gives the most data per dollar.
Why the Network Matters
manaMOBILE runs on T-Mobile's 5G network across all 50 states, including Hawaii. Some providers route traffic through proxy servers, which adds lag and can trigger geo-blocks. manaMOBILE connects you directly to the local network, so your data uses a local IP instead of a foreign proxy.
