nextSIM eSIM Data Plans for Guam

No, nextSIM does not provide a truly unlimited data eSIM for Guam. The plans that carry “Unlimited” in their name actually have a hard data cap—ranging from 1 GB to 2 GB per day—and after the cap is reached the speed is reduced to 512 kbps or 2000 kbps.

Travelers who need more data can choose from nextSIM’s fixed data plans. For example, the 20 GB 30Days Standard plan, the 30 GB 30Days Premium plan, the 40 GB 30Days Premium plan, and the 50 GB 30Days Premium plan all provide large data allowances for a set validity period. These fixed plans can be more cost‑effective for most users unless they require an extremely high data volume.

nextSIM does not offer any Guam eSIM plan that includes a phone number or SMS capability. All plans available from nextSIM for Guam are data‑only. Travelers can still use VoIP applications such as WhatsApp, Telegram or iMessage over the data connection for voice and messaging, but they should verify that those services are accessible in Guam before purchasing, as some destinations may block or restrict certain apps or VoIP services.

nextSIM provides 26 single‑country plans and 34 multi‑country plans for Guam, with prices ranging from $9.23 to $1, 261.66 and data caps between 1 GB and 50 GB. Some plans use a fixed data amount, while others apply a daily data cap; both types are available in the Guam portfolio.
