Vika LakiThe best eSIM for Hawaii depends on how you travel. Yesim, a Swiss travel eSIM provider, suits visitors who want one eSIM app, no ID check and a plan that starts when it connects to a local network. Holafly and Simify suit people who want an unlimited plan. Roamless suits people who want a plan with no expiry date. Hawaii is a US state, so your plan runs on US carriers such as AT&T, Verizon and T-Mobile.
The guide below compares real data plans, prices and networks for Hawaii travel. It also analyzes coverage across the islands, how much data you need and how to set up your eSIM before you fly.
Which eSIM provider is best for Hawaii?
A search for eSIM Hawaii shows dozens of providers. This guide compares seven travel eSIM providers with Hawaii or USA plans: Yesim, Saily, Nomad, Airalo, Roamless, Holafly and Simify. No single plan wins for every trip, so pick by how you travel:
- Short trip, light use: a 1 GB plan, such as Yesim at €3.10 for 30 days or Saily at €3.49 for 7 days.
- Two weeks with maps and video calls: a 10 GB plan. Yesim lists €14.00, Saily €20.49 and Roamless $19.95.
- Heavy use or a laptop on hotspot: an unlimited plan from Holafly or Simify, or a larger fixed plan.
- Several countries in one year: one app that covers many destinations. Yesim covers 200+.
- No expiry date: Roamless offers a pay-as-you-go option that does not expire.

Do you need an eSIM in Hawaii?
The answer depends on where you live. Hawaii is a US state. If you live in the US and use AT&T, T-Mobile or Verizon, your normal plan works there, so you probably do not need an eSIM. International visitors who travel to Hawaii are different. Data roaming fees from a foreign carrier add up fast, and a travel eSIM replaces them with a prepaid data plan.

What type of SIM card is best for tourists to Hawaii?
For most tourists, a travel eSIM is the best choice. You get an eSIM card in minutes, install it before the flight and skip the shop visit. Your home number stays on your home SIM. A local SIM needs a store visit and gives you a new number. Carrier roaming needs no setup and often costs more. A pocket Wi-Fi device is another option. You rent it and carry it around, and it needs charging. An eSIM sits inside your phone.
How much does Yesim’s eSIM for Hawaii cost?
Yesim lists these data plans for Hawaii in euros. Fixed plans last 30 days, and unlimited plans are priced per day:
| Plan | Price (EUR) | Price per GB |
|---|---|---|
| 500 MB, 1 day (first-time deal) | €0.45 | €0.90 |
| 1 GB, 30 days | €3.10 | €3.10 |
| 5 GB, 30 days | €9.00 | €1.80 |
| 10 GB, 30 days | €14.00 | €1.40 |
| 20 GB, 30 days (most popular) | €21.00 | €1.05 |
| 30 GB, 30 days | €26.60 | €0.89 |
| Unlimited, 1 day | €2.90 | n/a |
The bigger the fixed plan, the lower the price per GB. Longer unlimited plans cost less per day. Order two or more eSIMs and Yesim lists 10% off. ID verification is not required.
Yesim tip: if this is your first Yesim eSIM, the €0.45 first-time deal is a cheap way to install the eSIM and test it on your phone before you buy a bigger plan for the trip.
How do the best eSIM plans for Hawaii compare?
The table below lines up the main providers. Prices are the entry prices each provider shows for Hawaii or USA plans, in the currency the provider lists:
| Provider | Entry plan | 10 GB plan | Network | Hotspot | Good for |
|---|---|---|---|---|---|
| Yesim | €0.45 (500 MB, 1 day, first-time deal) | €14.00 (30 days) | Switches to the strongest local network | Depends on operator | One app for many countries, no ID check |
| Saily | €3.49 (1 GB, 7 days) | €20.49 (30 days) | Not stated on its page | No limits | Hotspot use and unlimited options |
| Nomad | From €5.33 | €23.49 (30 days) | Verizon / AT&T | Supported | Choosing your number of days |
| Airalo | $3.65 (1 GB, 7 days) | $28.89 (30 days) | T-Mobile and Verizon | Check plan page | Plans with voice minutes and SMS |

Which eSIM for Hawaii is better, Simify or Airalo?
Simify’s unlimited USA, Canada and Mexico plan costs $2.29 per day and runs up to 180 days, so it suits long stays. Airalo’s USA eSIM starts at $3.65 for 1 GB over 7 days and includes voice minutes and SMS, so it suits short trips with light data. Multiply the daily price by your number of days and compare the totals.
Which carrier has the best phone coverage in Hawaii?
Coverage is strongest around Honolulu and the main tourist areas of Oahu, Maui, Kauai and the island of Hawaii, also called the Big Island. Plans for Hawaii use AT&T, Verizon or T-Mobile, so US carrier maps apply. Providers also name towns.
Breeze, another travel eSIM provider, lists Honolulu on Oahu and Lahaina on Maui, plus Hilo on the Big Island. Holafly runs on AT&T, Nomad on Verizon and AT&T, Airalo on T-Mobile and Verizon, and Roamless on T-Mobile and AT&T. Yesim does not name one carrier on its Hawaii page and switches to the strongest available network. There is no separate Hawaii coverage map.
Signal can drop on remote roads, mountain stretches and quiet coastlines on any carrier. A plan that lists two networks, such as Verizon and AT&T on Nomad, can switch to the other one when one is weak.
Yesim tip: save offline maps of the island before you drive remote roads. A saved map still works when the signal drops.
How much data do I need for a trip to Hawaii?
The amount of data you need depends on what you do. Yesim’s page gives these rough numbers for 1 GB of data:
- About 1 hour of Full HD video streaming.
- 4 to 5 hours of low-quality video (240p).
- Around 20 hours of low-quality music.
- 1 to 1.5 hours of HD video calls.
Maps, messages and light browsing use far less. As a rough guide for one week, 3 to 5 GB covers light use, 10 GB covers photos and streaming, and an unlimited plan suits people who work online or share a hotspot.
What if I run out of data?
If you run out of data or need more data, top up in your provider’s app or add a data plan. Yesim lists balance top-up as available. Some providers require a new eSIM for each top-up, so check this before you buy.
Yesim tip: check your eSIM data usage in the Internet section of the Yesim app each evening. You can add data before you run out.
Is an unlimited data plan worth it for Hawaii?
Unlimited plans remove the worry about gigabytes. They suit long stays, heavy video use and hotspot sharing. Unlimited rarely means full speed all day. Most providers slow your speed after a daily high-speed data allowance, and Yesim notes that speed can be reduced under the network operator’s Fair Usage Policy. For one week of maps and messages, a fixed data plan costs less.
How do I set up and activate an eSIM for Hawaii?
Setup takes a few minutes. Do it at home on Wi-Fi:
- Check that your phone is eSIM compatible. Dial *#06# or use the compatibility checker.
- Choose your destination and eSIM plan, then pay to get your QR code.
- Download the Yesim app and tap Install eSIM, or scan the QR code in your phone settings.
- Keep your home SIM for calls and texts, and set the eSIM as your data line.
- Turn on data roaming for the eSIM line when you land. Turn it off for your home SIM.
Your QR code works on one phone only, so do not share it. You can use an eSIM next to your physical SIM card with dual SIM, so your WhatsApp number stays the same. Most recent phones can store more than one eSIM, so an existing eSIM stays in place. If the eSIM shows no signal, enable data roaming for that line first.
Yesim tip: install your eSIM before your trip. On Yesim, the plan validity starts when the eSIM connects to a compatible network, and you can activate within 180 days of purchase. You lose no days while you wait for your flight.
Will my phone support an eSIM?
Most recent iPhone and Android phones do. A carrier-locked phone can block a travel eSIM, so check if your phone is carrier-locked before you buy.

What is the downside of an eSIM?
eSIMs have a few limits. Check these before you buy:
- Your phone must be eSIM compatible and free of a carrier lock.
- Most travel eSIMs work as an eSIM for data only. Calls and texts run through apps such as WhatsApp or FaceTime.
- A QR code works on one phone, so a new phone means a new setup.
- Fixed data plans can run out, so check your balance throughout your trip.
Can I use my eSIM as a hotspot in Hawaii?
Often yes. Limits differ by provider. Saily lists no hotspot limits, Nomad supports tethering and Breeze includes tethering on every plan. Holafly shares 1 GB per day for hotspot use. Yesim lists hotspot as depending on the operator, so check the plan details if you plan to tether a laptop.
Which eSIM should you choose for Hawaii?
Pick by trip length and data use. For a week of maps and messages, a fixed plan of 3 to 5 GB is enough. For two weeks or more, choose 10 to 20 GB or an unlimited plan. For several countries in one year, a single app saves repeat setup.
Yesim, an eSIM service for 200+ destinations, lists fixed plans from 1 GB to 30 GB and a 1-day unlimited plan, with no ID check. See Yesim’s Hawaii eSIM plans or download the Yesim app before you fly.
