Before you read this guide, you may wonder if you actually need a SIM card in Guam.

If you don’t mind not having Internet, you’ll likely find free Wifi in restaurants, shopping malls, and hotels.

That said, if you need data to get around, call a cab, or translate Chamorro – you may want to get a SIM card for your travels in Guam.

Best SIM Cards In Guam

If you’re traveling in Guam, we recommend using a SIM card from Docomo, GTA Teleguam, IT&E, or Airalo. (I’ll get back to Airalo later on, so keep reading to learn more!)

That said, if you’re planning on visiting other countries during your trip to Oceania, you might want to make sure to pick an option that offers coverage in other Oceanian countries.

How To Buy A SIM Card In Guam

You can either buy a Guam prepaid SIM card in person in some international airports, mobile provider stores, convenience stores, or online.

Usually, you can expect higher costs and low data offers at the airport, so we don’t recommend buying a SIM card at the airport.

That said, you won’t necessarily find SIM card shops in every airport, so it’s essential to keep this in mind. And, when you see a shop, you might also have limited options.

For this reason, I’d recommend buying a SIM card directly from the mobile provider store. Note that you may need your passport to buy one.

Although, this means you won’t get data right upon your arrival. So, if you prefer to be connected at all times, you could use an eSIM or purchase an Oceanian prepaid SIM card online.

Now, let’s take a look at the data plans offered by Docomo, GTA Teleguam, and IT&E.

  • 3 GB, valid for 3 days for  USD 7.50
  • 7 GB, valid for 7 days for  USD 15.00
  • 14 GB, valid for 14 days for  USD 30

GTA Teleguam SIM Cards

Overall, we think Docomo is the best option if you plan to buy your SIM card in person.

That said, any would do if you can’t find their store!

How To Buy A Guam Prepaid SIM Card Online

If you wish to have your SIM card ready for your arrival, you could purchase it online or on websites like Amazon.

You’ll find different plans on Amazon. For example, the OneSimCard works in more than 200+ countries and gives you data for $0.01 per MB. Guam is included.

But there are many other options worth considering, so have a look and make sure the countries you plan on visiting are listed.

Finally, the last option is to buy an eSIM card for Guam or, if you’re traveling to multiple countries, an eSIM plan for Oceania.

How To Buy A Guam eSIM

eSIM is a new concept that allows you to have a virtual SIM card inside your phone.

If your mobile phone supports eSIM cards – it’s definitely one of the best options to get data in Guam.

Final Thoughts On Guam SIM Cards

As you can see, getting a prepaid SIM card in Guam or even an eSIM for your travels in Guam is pretty straightforward.

You’ll even be able to stay connected wherever you go in Oceania without changing your SIM card, especially if you purchase an Oceania or global plan.

I believe the eSIM card is the most convenient way to get data in Guam if you wish to have data upon your arrival.

This way, you won’t need to go to a store to buy a SIM card.

Obviously, you need to make sure your mobile phone supports eSIM first.
