nextSIM eSIM Data Plans for Guam

NextSIM does not provide a true unlimited data eSIM for Guam. All plans that are labeled with “Unlimited” actually contain a fixed data allowance of 1GB or 2GB and, once that limit is reached, the speed drops to 512kbps or 2000kbps. Because the data cap is still in place, these plans are not unlimited in the sense of ongoing high‑speed data without limits.

Travelers who need more data for a trip to Guam can turn to nextSIM’s fixed‑data plans. For example, a 20GB 30Days Standard plan is available for Guam, as is a 10GB 30Days Standard or a 5GB 30Days Standard. These options provide consistent high‑speed data for the full validity period and are typically more economical for users who consume a large amount of data.

nextSIM does not provide a Guam eSIM that includes a local phone number or SMS capability. The provider offers only data‑only eSIMs for Guam. Travelers can still use internet‑based messaging and calling apps such as WhatsApp, Telegram, or iMessage over the data connection.

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.
