merdata eSIM Data Plans for Guam

merdata does not provide an unlimited data eSIM for Guam.
The available plans for Guam have fixed data caps of 10GB or 20GB and fixed validity periods of 1, 30, or 90 days. Travelers who need more data can choose from the fixed data plans, such as the eSIM Guam 20 GB 30 days or the eSIM Guam 10 GB 30 days, which offer large data allowances at a set validity. These fixed plans are generally more cost‑effective than purchasing pay‑as‑you‑go credit for very heavy data usage.

Merdata does not provide a Guam eSIM that includes a phone number or SMS capability. All Guam plans from this provider are data‑only. Travelers who need voice or text services can use popular VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection. However, some destinations may restrict or block certain apps or VoIP services, so it is advisable to verify that the apps you rely on are accessible in Guam before purchasing a plan.

Prices span from about $9.23 to $103.55, allowing travelers to choose between lower‑cost daily or weekly packages and higher‑priced long‑term or high‑data options.
