eSIMs for Guam: The Best Travel Plans | 2024 Guide

Guam – an unincorporated territory of the United States in the Pacific Ocean.

It is closer to Southeast and East Asia and Oceania than mainland United States.

Known for its stunning beaches, crystal clear ocean water, and terrific resorts.

The Northern Mariana Islands – the Commonwealth of the Northern Mariana Islands (CNMI) is another unincorporated territory of the United States.

Known for its famous islands like Saipan, Tinian, and Rota.

Each island has its unique traits. Bord Island on Saipan. The prehistoric ruins in Tinian. And the relaxed atmosphere in Rota.

In general, there should be no reason to be bored when in Guam & the Northern Mariana Islands. There is a lot to do.

But before you share your colorful Guam experiences online, be aware that international roaming can be expensive.

Travel eSIMs can be a much more affordable way to stay connected, even in Guam.

How much will a travel eSIM for Guam cost?

You can get a travel eSIM for Guam for as little as 10 USD for unlimited data (4 days) to 49 USD for unlimited data (30 days) from Airalo.

While this may sound a bit pricey but international roaming will be even more expensive.

So yeah, these travel eSIMs can be worth it.

In this guide, I will go over the travel eSIM options offered by Airalo. Let's go.

eSIMs offered by the Guamanian Mobile Operators

Suppose you want to get the best service and reception available in Guam.

In that case, it is better to get a SIM card or travel eSIM from the local mobile operators, which in this case would be the Guamanian ones.

Not only will you not have to deal with latency, but you also get a higher priority on the network because you are a direct customer of the mobile operator instead of a roamer.

And with most travel eSIMs, you are roaming on the network(s) of the local mobile operator(s).

But that is not always the case – the slow speeds part, that is.

Some mobile operators throttle the speeds of prepaid customers because they want more people to get a postpaid plan.

Unfortunately, travelers cannot get postpaid plans – so one way to avoid throttling is by using a travel eSIM.

Yes – travel eSIMs sometimes have faster speeds than native prepaid customers because of throttling.

You have one option for getting an eSIM for your trip to Nauru: Airalo (with Håfa Adai).

One of the main advantages of getting a travel eSIM for Guam is that you can set up the eSIM before arriving in Guam and activate it upon landing.

Moreover, I have plenty of experience with the eSIMs from Airalo, so I can vouch for them – so can many Phone Travel Wiz readers!

So let's go over what the travel eSIMs offer for Guam!


Airalo eSIMs for Guam (Håfa Adai)

If you have read any of my eSIM or SIM card buying guides before, then you know I am a big fan of Airalo.

Not only does Airalo have eSIMs for most countries (around 190 countries) of any eSIM platform, but they are also often one of the cheapest while offering fantastic service in terms of speeds and reception.

That is because Airalo usually partners up with the mobile operator with the best coverage, the fastest speeds, both, or even multiple operators.

That way, you get the best bang for your buck, I have to say.

In the case of Guam, the Håfa Adai eSIM uses the GTA network.

Airalo Håfa Adai eSIM Pros

Are there any (more) reasons why you should get the Håfa Adai eSIM? Yes, there are:

  • You can activate your Håfa Adai eSIM as soon as you land in Guam
  • You get full (up to 4G/LTE) access to Docomo Pacific's network
  • Håfa Adai eSIMs are affordable (especially compared to roaming)
  • Multiple top-ups can be purchased when you are out of data or when your initial plan expires easily on the Airalo site or apps

I could list many more pros, but these are the major ones.

Unfortunately, there are some cons to be aware of.

Airalo Håfa Adai eSIM Cons

Why should you not get the Håfa Adai eSIM?

  • The Guamanian mobile operators, including Docomo Pacific itself, have much more generous data allowances
  • While you get access to Docomo Pacific's network, your speeds may not be as fast as going with Docomo Pacific itself because you will be roaming on their networks (and not be a native customer)
  • There is no 5G NR access with the Håfa Adai eSIM (yet)
  • You cannot call or text with the Håfa Adai eSIM (nor can you receive them – you get no (local) phone number)

Airalo Håfa Adai eSIM Overall Thoughts

The Håfa Adai eSIM is a convenient eSIM that can be purchased before going to Guam and can be activated upon arriving.

You get access to one of Guam's best networks with the Håfa Adai eSIM.

Remember, you cannot call or text with the Håfa Adai eSIM, as it is a data-only eSIM.

Consider a Guamanian SIM card if calling and texting is important, but you have to deal with the (e)SIM (card) registration laws.


Overview of the Best eSIMs for Guam (Airalo)

In this guide, I went over Airalo's Håfa Adai as the only (reasonably priced) eSIM for Guam.

I recognize that there are other eSIM providers that do offer services for Guam.

But they are either crazy expensive or the quality of service is whack (based on my experience or the experiences of other Phone Travel Wiz readers).

But you are free to try them out and let me know if they were any good 😀.


Buying a SIM Card in Guam

Do these eSIMs not sound appealing to you, or does your phone not support eSIMs (but still thought this guide was insightful enough that you read it until the end)?

Consider getting a Guamanian SIM card instead – that linked guide is the most extensive SIM card buying guide for Guam on the web, packed with insightful information and tips.
