Lumbus does not provide an unlimited data eSIM for Guam. Travelers can choose from fixed data plans instead; for example, the Guam 20GB 30Days plan offers 20GB of data for 30 days at $80.99 USD, and the Guam 10GB 30Days plan provides 10GB for 30 days at $46.99 USD. These fixed plans are typically more economical for the majority of users, whereas an unlimited option would only be necessary for very heavy data consumers.
Lumbus does not provide a Guam eSIM that includes a phone number or SMS capability. All of Lumbus’s Guam offerings are data‑only plans; if you need voice or text services you will need to use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection.
For Guam, Lumbus offers 6 single‑country plans and 7 multi‑country plans. The single‑country options are priced between $7.99 and $133.99 and feature data caps ranging from 1 GB to 20 GB over validity periods of 7 to 365 days. The multi‑country plans share the same price and data ranges, also allowing tethering, and provide travelers with broader coverage that includes Guam.
