The best eSIM for Guam in 2026. Six eSIM brands priced for Guam on the same day: Airalo is cheapest for unlimited, Nomad for a bucket, why US visitors may need nothing, and which to buy.
Prices read on 28 September 2026. Six travel eSIMs get most of the traffic for this search, and all six sell something that works on Guam. We priced them on the same day, for a long weekend in Tumon, a week around the island, two weeks and a month, and read the fine print on unlimited. In Guam our prices are high and Airalo is far cheaper, and this page says so plainly. If you live in the US, read the last question first: your own plan may already cover you.

Airalo is the cheapest unlimited plan for Guam at every length we priced: $8 for 3 days, $18 for 7 days, $35 for 15 days and $62 for 30 days, on GTA. Holafly charges $50.50 for 15 days and $73.90 for 30 days on Docomo Pacific. Ringo Light charges $139.99 for 2 weeks and $277.99 for 30 days, one payment each, nothing renews. Airalo's 15 days costs $104.99 less than our 2 weeks, and its month $215.99 less than ours. We would rather you read that here than at checkout.
Read what unlimited means before you pick. Airalo gives 2 GB a day at full speed, then 1 Mbps, which is still enough for maps and messages. Holafly states no daily cap for your own phone and limits sharing to 1 GB a day. Saily's only unlimited that works on Guam is its Global plan, 30 GB for 30 days at $59.99, then 1 Mbps. Ringo Light has no speed cap: the 2 weeks starts with 10 GB and the 30 days with 20 GB, and when you have used 80% we add 10 GB once and charge the $139.99 top-up. A heavy two weeks with us costs $279.98 and a heavy month $417.97. Holafly's 30 days at $73.90 is the cheaper way to use a lot of data without a daily cap.
For a short trip, Ringo Light sells no 3-day or 7-day plan. Airalo sells 3 days of unlimited at $8 and a week at $18.
Guam has three mobile networks: Docomo Pacific, GTA and IT&E. Airalo names GTA, Holafly and Nomad Docomo Pacific, and Ubigi both. All of them cover Tumon, Hagåtña, the airport and the main roads well. Signal gets thinner in the far north around Ritidian, on inland trails and along stretches of the southern coast, so save an offline map of the island before you drive south.
Guam is a US territory. It uses the US dollar, its phone numbers start with +1 671, and many US phone plans treat it as home. There is little public transport outside Tumon, so most visitors hire a car and navigate with a maps app.
Nomad, $29 for 10 GB. For 30 days, the cheapest 10 GB for Guam, on Docomo. Also 3 GB for $15 and 5 GB for $19, both for 30 days, and 1 GB for 7 days at $11. No 20 GB.
Ubigi, $9 for 1 GB. For 7 days, the cheapest small plan, on Docomo Pacific and GTA. 3 GB for 15 days at $19; its Guam 10 GB lasts only 8 days, at $39.
Saily, $14.99 for 1 GB. Its only Guam plan, 7 days. Its Global plans also work here: 10 GB for 30 days at $44.99. Its listing is from June; saily.com would not load for us.
Airalo and Holafly, no buckets. Both sell unlimited days only for Guam.
Ringo Light, no buckets. Our 2 weeks starts with 10 GB for $139.99 and our 30 days with 20 GB for $277.99. For a fixed amount of data, Nomad, Ubigi and Saily are all far cheaper in Guam, and Airalo's unlimited is cheaper still.
Ringo Light is our own data eSIM, sold to fund the full Ringo, one plan that works everywhere with your own number ported onto it. For Guam it sells two trips, both unlimited data at full speed with no speed cap: 2 weeks at $139.99, starting with 10 GB, and 30 days at $277.99, starting with 20 GB. Each adds 10 GB once at 80%, charged at $139.99. One payment, nothing renews. The eSIM arrives by email in seconds and installs in one scan, no app.
In Guam our prices are high. Airalo's unlimited at $35 for 15 days or $62 for 30 days is the better buy for most visitors, and Holafly's $73.90 month if you want no daily cap. None of our regional trips covers Guam, so there is no cheaper Ringo Light route in.
The card to buy it is just below this article.
You live in the US. Check your own plan first. Many US plans treat Guam as home, and then you need no eSIM at all.
A long weekend in Tumon. Airalo unlimited, 3 days, $8. Ringo Light sells no 3 days.

You need your own number to keep ringing. None of these travel plans does that. The full Ringo, which Ringo Light funds, ports the number you have.
What to do in Guam, and what your phone needs for it. Eight places most first trips include, from the hotels of Tumon Bay up to Ritidian in the north and down the southern coast to Umatac and Cocos Island, with the one thing your data does for you at each. The island is about 50 kilometres long, and a hire car reaches all of them in a day.
Tumon Bay, Tumon. The main hotel strip, on a shallow bay protected by a reef and a marine preserve. Calm water for snorkelling in the morning, sunsets over the sea in the evening. A red trolley bus runs along the hotels. A maps app shows the stops and how far you are from the next one.
Two Lovers Point, Puntan Dos Amantes, above Tumon. A cliff high above the north end of Tumon Bay, named after a Chamorro legend of two lovers. A viewing deck looks down the whole bay; go late in the afternoon for the light. It is a short drive from the hotels. A maps app gets you up the right road from Tumon.
Ritidian Point, Guam National Wildlife Refuge, northern tip. A white sand beach and forest trails at the far north of the island, inside the wildlife refuge. The currents can be strong, so read the refuge signs before you go in. Signal is weak up here. Check the refuge's opening days before you drive out and save an offline map.
Plaza de España and Latte Stone Park, Hagåtña. The ruins of the Spanish governor's palace stand in the plaza next to the cathedral of Dulce Nombre de Maria. A short walk away, Latte Stone Park shows the stone pillars ancient Chamorro houses stood on. Both are free and close together. Park once and walk between them with a maps app.
Talofofo Falls, Talofofo. A two-tier waterfall in a park on the east side, reached by a cable car. The park also leads to the cave where Shoichi Yokoi, a Japanese soldier, hid in the jungle until 1972. Look up the park's opening times in the browser before you drive over.
Inarajan natural pools, Inarajan, south coast. Saltwater pools inside the reef, fed by waves breaking on the rocks outside. Swim on a calm day; stay out when the surf is big. Check the surf and weather forecast on your phone before you get in.
Fort Soledad, Umatac. A small Spanish fort with a stone lookout above Umatac Bay, where Magellan is said to have landed in 1521. The view takes in the whole bay and village. The southern coast road has patchy signal. Download the offline map before you leave Hagåtña.
Cocos Island, Off Merizo, south coast. A small island inside a wide lagoon at the southern tip of Guam, with beaches and shallow water for snorkelling. Boats run across from Merizo. Book the boat in advance and keep the booking on your phone; signal on the island can be weak.
We priced Airalo, Holafly, Saily, Nomad, Ubigi and Ringo Light for Guam on 28 September 2026, all on the same day, in US dollars. Each rival's price comes from its own website where it showed dollars, otherwise from an esimdb.com listing, and every source and its date is listed below. Ringo Light's prices come from the catalogue our checkout charges.
We compare the trips people actually book: a week, two weeks and a month of unlimited data, and a 10 GB bucket. We read each brand's fair use and speed rules and quote them as the brands state them. We did not run speed tests, so this page makes no speed claims for any brand.
Ringo Light is our own product. We put it in the table on the same terms as everyone else, and where a rival is the better buy the page says so.
Left out: Maya Mobile, we could not read its own prices for this country on the day, so it stays out rather than being guessed.

For unlimited data, Airalo: on 28 September 2026 it charged $8 for 3 days, $18 for 7 days, $35 for 15 days and $62 for 30 days. For a bucket, Nomad at $29 for 10 GB for 30 days, or Ubigi at $9 for 1 GB for 7 days. Ringo Light charges $139.99 for 2 weeks and $277.99 for 30 days, far more than Airalo.
Guam has three networks: Docomo Pacific, GTA and IT&E. Airalo uses GTA, Holafly and Nomad Docomo Pacific, and Ubigi Docomo Pacific and GTA. Saily does not name its network on its listing. All cover Tumon, Hagåtña and the main roads, and get thinner in the far north and on the southern coast.
Every brand has a limit somewhere. Airalo slows you to 1 Mbps after 2 GB a day. Saily's Global unlimited slows after 30 GB, Ubigi's World monthly after 60 GB. Holafly states no daily cap for your own phone and limits sharing to 1 GB a day. Ringo Light has no speed cap: it starts with 10 or 20 GB and adds 10 GB once at 80%, charged.
Often not. Guam is a US territory, and US phone plans usually treat it as home, so many US travellers use their own plan there with nothing to buy. Plans differ, so check your carrier's coverage page or app for Guam before you fly. If your plan charges for Guam, or you come from anywhere else, one of the eSIMs above is the answer.
