Where to buy a SIM card in Hawaii?
You can purchase a prepaid SIM card before your trip, find one at Hawaii’s airports or local stores, or skip the search altogether and instantly activate a digital eSIM. Buying a Hawaii SIM card varies based on whether you prefer to get connected before your flight or after landing.
Buy a SIM card for Hawaii before you travel
If you want to land with mobile data ready to go, you can purchase a travel SIM card for Hawaii online from a third-party retailer and have it shipped to your home before departure.
Remember to order your SIM card well in advance to make up for any potential shipping delays. Here are a couple of international SIM retailers that deliver to Australia, the USA, the UK, and Canada:
- SimOptions
- Amazon
- OneSIM card
- TravelSim
It’s also worth familiarising yourself with the SIM registration process since you’ll be responsible for activating your SIM card to use mobile internet in the US.
Buy a SIM card after you land in Hawaii
If you prefer to buy your Hawaii SIM card in person, you’ll find several locations upon arrival and after a little bit of exploring:
- Daniel K. Inouye International Airport (Honolulu Airport): Look for T-Mobile and AT&T kiosks in the arrival terminals.
- Local carrier stores: Visit T-Mobile stores, AT&T outlets, or Verizon retailers in Honolulu, Waikiki, Maui, and Kauai to purchase Hawaii prepaid SIM card plans.
- Convenience stores: ABC stores, Walmart, and Target sell prepaid Hawaii SIM card plans.
- Electronics stores: Head to Best Buy or Costco to get SIM card plans for Hawaii.
Choose a digital eSIM for Hawaii
This is the most convenient and flexible way to use your phone in the US for tourists. If you have an eSIM-compatible phone, you don’t need to wait for shipping or swap out your physical SIM card for a new one.
Providers like Holafly offer eSIMs for Hawaii (and the United States, plus 200 other destinations) that you can activate instantly by scanning a QR code. You can enjoy unlimited data and excellent coverage on AT&T’s network all across the islands.
How much is a SIM card in Hawaii?
Tourists can expect to pay anywhere from $15 to $60 USD for a prepaid SIM card in Hawaii, depending on how comprehensive your SIM card plan is, data usage needs, roaming flexibility, and overall budget.
Best prepaid SIM cards for Hawaii
You can choose a Hawaii SIM card from the top mobile operators in the area: T-Mobile, AT&T, and Verizon. Each provider offers a few prepaid SIM card options; here’s a brief overview:
T-Mobile SIM card for Hawaii
T-Mobile offers three different SIM card plans for tourists in Hawaii (and other destinations in the US) with varying data allowances:
- 10 GB and high-speed hotspot sharing at $40/month
- Unlimited data and 3G hotspot sharing at $50/month
- Unlimited data and 5G hotspot sharing at $60/month
All plans also include unlimited talk and text within the United States. Once you use up the high-speed data limit, you’ll be able to use unlimited data at capped speeds. Make sure to calculate your data usage to avoid running out of data too quickly.
AT&T SIM card for Hawaii
AT&T offers a selection of prepaid plans for travelers in Hawaii and other states in the US:
- 5 GB high-speed data for 30 days at $30 plus taxes and fees
- 30 GB high-speed data for 30 days at $45
- 50 GB high-speed data for 30 days at $55
- Unlimited high-speed data for 30 days at $65
- 16 GB high-speed data per month for 365 days at $300
Most of these plans also allow hotspot sharing and unlimited calls and texts within the US. That said, the prices above only apply if you activate AutoPay, and cost around $10/month more without the AutoPay option enabled.

Verizon offers some popular plans for travelers visiting Hawaii and other destinations in the US:
- 15 GB and hotspot sharing at $35/month

- Unlimited data and hotspot sharing + 50 GB premium network access at $60/month
The prices above apply if you’ve got AutoPay enabled. Not having AutoPay adds an extra $10/month to every plan.

How to register your Hawaii SIM card
You’ll have to follow specific tourist requirements when registering your local Hawaii SIM card. When purchasing the SIM card in person, a staff member will likely help you. Online SIM card purchases mean you’ll have to figure out the activation process yourself.
Here’s what you will be asked for at the counter, supermarket, or online:
- Valid photo identification and/or passport (and a copy)
- Local contact details
- An unlocked phone (from your home carrier) that supports Hawaii frequency bands
- Proof of stay/accommodation (in some cases)
- Working payment method (local currency in cash or a credit/debit card)
While you can access local prepaid plans, providers, and rates, getting a local physical SIM card can still be a hassle, especially after a long flight.
With a digital SIM, you can skip the lines, avoid lengthy registration processes and paperwork, and get instantly connected the moment you land.
What is the best SIM card for Hawaii?
Picking the best SIM card for Hawaii depends on what you’re looking for on your travels. Are you prioritizing high data allowances or unlimited calls/texts? The right choice depends on your connectivity needs and budget. Each top provider in Hawaii has its strengths.
However, if your priority is convenience, no SIM swapping, and a straightforward activation process, an eSIM for Hawaii is the ideal choice.
Match your eSIM to your vacation
Choose a plan lasting between 1 and 90 days so you never pay for days or data you don't use.
