nextSIM eSIM Data Plans for Guam

nextSIM does not provide a truly unlimited data eSIM for Guam. The plans that carry “Unlimited” in their names actually offer a fixed amount of high‑speed data—typically 1GB or 2GB per day—and after that amount is reached the connection speed is throttled to 512kbps or 2000kbps. These are fixed data plans, not unlimited bundles.

For travelers who need more data, nextSIM sells fixed data plans with larger caps. For example, the Guam 20GB 30Days Standard plan gives 20GB of 5G data to be used over 30 days, and the Global 50GB 30Days Premium plan offers 50GB of 5G data covering Guam and many other countries, also usable within a 30‑day window. These plans allow high‑speed data for the full allotted amount before any speed reduction or expiration.

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.
