Superalink eSIM Data Plans for Guam

Superalink does not provide an unlimited eSIM plan for Guam. All of its available Guam‑only eSIMs are fixed data plans with restrictions on the amount of data that can be downloaded: 20 GB, 15 GB, or 10 GB, each valid for 30 days. Because the data caps are fixed, the plans are not unlimited, but they offer a full 5 G network within Guam and allow tethering. Travelers who need more than 20 GB or who want a truly unlimited experience would need to look at alternative providers or consider a different plan type.

Superalink does not offer any Guam eSIM that includes a phone number or SMS capability. Their Guam plans are data‑only, so they provide internet access only. Travelers who need voice or text can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, though they should confirm that those services are accessible in Guam before purchasing.

Superalink provides both single‑country and multi‑country data plans for Guam.
The single‑country catalogue contains 17 plans, and the multi‑country options also total 17. The available plans span a price range from $3.00 to $48.11 and offer data caps between 1 GB and 20 GB, with validity periods from 1 up to 30 days. Some offerings feature a fixed data amount while others apply a daily data cap, giving customers flexibility in how they consume data during their stay.
