eSIM Guam: five uncapped plans and no gigabyte option

What does an eSIM Guam plan cost?

All the figures here come from Airalo, and only from Airalo. Five plans, each read off airalo.com on 8 October 2026, in US dollars. We have priced no other seller for Guam: not Saily, Holafly, Nomad, eSIMCard or eSIM Go. Treat this as one company's price list rather than a survey of the market. This page is desk research from public sources; we did not install or test any of these plans. Guam is unusual in our data: all five plans are uncapped, and none is sold by gigabyte. That means a cost per gigabyte cannot be computed, so we compare cost per day.

The full Guam travel SIM price list

Verified 8 October 2026. Every row is Airalo's Håfa Adai product.

Which length should you buy?

The daily cost drops from $2.67 on the 3-day plan to $2.07 on the 30-day plan. The step from 3 days to 7 adds $10 for four more days. A 30-day plan costs $27 more than a 15-day plan.

For a long weekend the 3-day plan at $8 is the obvious buy. For a week, the 7-day plan at $18 costs less per day than the 3-day plan. Choose by your dates; the longer plans only pay off if you will use them.

What the thin list does and does not tell you

Our data holds no metered Guam plan, so we cannot say what 1 GB or 5 GB would cost, and we cannot tell you whether the uncapped plans carry a fair-use limit. Airalo's page is where any such terms would appear and we did not extract them. We hold no host network for these rows either.

Local carriers: what we could confirm

Docomo Pacific's own site, which we read today, lists prepaid plans and a section for visitors to Guam and the Northern Mariana Islands. Its home page does not mention eSIM, so we cannot say whether it sells one. We did not find a source we could read that confirms how US carriers treat Guam, so check your home plan before you buy anything.

If you are shopping for a cheap eSIM for Guam, start with the rate per gigabyte rather than the headline price. A Guam eSIM is only good value once you know how much data you will use, and a Guam travel SIM from any seller should be compared on the same terms. Think of this as one Guam data plan list to check against others, not the last word.

For the seller across every country we hold, see our Airalo page. For how this rate compares with the rest of the site, see the cheapest eSIM plans and the provider comparison, and for the wider region see the Asia guide, the nearest regional page we have.
