Saily eSIM Data Plans for Guam

Saily does not provide a truly unlimited high‑speed data plan for Guam. All of the plans labeled with “UNLIMITED” in their names have a fixed cap of 30GB; after that amount is used the speed drops to a reduced rate, either 1024 kbps or 1 kbps, depending on the product. Because of the cap, the data is not truly unlimited for travelers who need unrestricted high‑speed access.

Instead, Saily offers fixed‑data plans that can be used on Guam and around the world. For example, a 30GB plan valid for 90 days costs $119.99, and a 20GB plan valid for 365 days is priced at $66.99. These plans provide a larger data allowance and may be more cost‑effective than the “UNLIMITED” name products for most users.

Saily does not provide any eSIM plans for Guam that include a local phone number or the ability to send or receive SMS. Travelers looking to stay connected in Guam can purchase only data‑only eSIMs from Saily. For voice and messaging, they can rely on popular VoIP applications such as WhatsApp, Telegram, or iMessage, which operate over the data connection and do not require a traditional phone number or SMS capability.

Saily offers a single-country plan that covers only Guam, alongside a separate set of multi‑country plans that include Guam within a broader coverage network. In total, there is 1 single‑country deal for Guam and 11 multi‑country packages that list Guam among their destinations. Prices for these plans range from about $8.99 to $159.99, while data capacities span from 1 GB up to 30 GB, providing options for both short‑term travelers and those needing more extensive usage.
