nextSIM eSIM Data Plans for Guam

nextSIM does not provide a truly unlimited high‑speed data plan for Guam. All plans labeled “Unlimited” in the catalogue actually limit high‑speed data to 1GB or 2GB (per day or total) and then throttle speed to 512kbps or 2000kbps when the limit is reached. Travelers who need larger, uninterrupted data allowances can choose from fixed‑data options such as the 20GB 30‑day plan at $153.78 USD, the 10GB 30‑day plan at $85.60 USD, or the 5GB 30‑day plan at $46.63 USD. These fixed plans may offer greater cost efficiency for those who use more data than the capped “Unlimited” plans permit.

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 lists 22 single country plans and 16 multi country plans that cover Guam. Prices range from $6.97 to $349.32 and data caps vary between 1 GB and 20 GB. The catalogue includes both fixed data plans, which provide a set amount of data for the validity period, and daily data cap plans, which allow purchase of a daily allotment for travelers on short stays.
