eSimfly eSIM Data Plans for Guam

eSimfly does not offer a truly unlimited data eSIM for Guam. The plans that carry the name “Guam Unlimited” actually provide 3 GB of high‑speed data per day, and after that quota the speed is reduced.
For travelers who need more data, eSimfly offers fixed‑amount plans such as Guam 20GB 30 days or Guam 10GB 30 days, which give a larger total allowance for a single cost. These fixed plans can be more cost‑effective for users who consume a lot of data compared to purchasing several daily‑limited plans.

eSimfly does not provide an eSIM for Guam that includes a local phone number or SMS capability. Only data‑only eSIM plans are available for this destination.

Travelers who need to make calls or send messages can use VoIP applications such as WhatsApp, Telegram, or iMessage, which operate over the data connection provided by the eSIM.

eSimfly provides a mix of single‑country and multi‑country options for travelers visiting Guam. For Guam, the service offers 12 single‑coverage plans and 4 multi‑coverage plans that include the island among other destinations. The plans span a price range from about $8.11 to $105.63 and offer data amounts between 1 GB and 30 GB, with validity periods that can last from one day up to thirty days. Some plans feature daily data caps that reset each day, while others offer a fixed data allocation that does not change during the validity period. Tethering is permitted on all applicable plans.
