Visiting Guam soon? Make sure to know what to expect when it comes to purchasing a Guam SIM card.
In this guide, weâll explain where to buy a SIM card in Guam in person and online. Weâll also discuss prepaid SIM cards and eSIMs if your mobile supports them.
Before you read this guide, you may wonder if you actually need a SIM card in Guam.
If you donât mind not having Internet, youâll 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 â you may want to get a SIM card for your travels in Guam.
Best SIM Cards In Guam
If youâre traveling in Guam, we recommend using a SIM card from Docomo, GTA Teleguam, IT&E, or Airalo. (Iâll get back to Airalo later on, so keep reading to learn more!)
That said, if youâre 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 donât recommend buying a SIM card at the airport.
That said, you wonât necessarily find SIM card shops in every airport, so itâs essential to keep this in mind. And, when you see a shop, you might also have limited options.
For this reason, Iâd 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 wonât 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, letâs take a look at the data plans offered by Docomo, GTA Teleguam, and IT&E.
Docomo Pacific SIM Cards
Docomo Pacific offers three different types of tourist plans:
- 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
GTA Teleguam has three different prepaid plans available:
- Unlimited data, valid for 1 day for USD 2.50
- Unlimited data, valid for 5 days for USD 12
- Unlimited data, valid for 15 days for USD 35
IT&E SIM Cards
IT&E offers several main SIM-only plans for tourists:
- Unlimited data, valid for 1 day for USD 2.50
- 1 GB daily, valid for 7 days for USD 15
- 40 GB, valid for 30 days for USD 60
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 canât 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.
Youâll 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 youâre 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.

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.
Youâll 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 wonât need to go to a store to buy a SIM card.
Obviously, you need to make sure your mobile phone supports eSIM first.
