nextSIM eSIM Data Plans for Guam

NextSIM does not provide a truly unlimited high‑speed data eSIM for Guam. The plans that carry the “Unlimited” label actually include a fixed allowance of 1GB or 2GB per day; when the limit is reached, the speed drops to 512 kbps or 2 Mbps. Travelers looking for larger, uninterrupted data volumes can choose from the fixed‑data plans such as the 20GB 30 days eSIM, priced at $97.38 USD, or the 10GB 30 days standard eSIM, priced at $54.32 USD, which offer ample bandwidth without the speed throttling that accompanies the “Unlimited” name.

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.

The nextSIM catalogue lists 22 single‑country plans that cover Guam only, along with 16 multi‑country plans that include Guam as part of a broader regional bundle. The plans are divided into two types: fixed data amount packages that give a set amount of data for the full validity period, and daily‑data‑cap packages that allot a certain amount of data each day during the plan’s active period. Across all nextSIM offers the price ranges from about $6.88 to $344.41, data caps vary between 1 GB and 20 GB, and validity can be from a single day up to thirty days.
