4S eSIM eSIM Data Plans for Guam

4S eSIM does not provide a truly unlimited data eSIM for Guam.
Plans that include “Unlimited” in the name, such as Guam 3GB Unlimited - 1 Days or Guam 5GB Unlimited - 7 Days, provide a set data allowance and after that data the speed is reduced to 1000kbps. The “Unlimited” label refers only to the name, not to an uncapped data stream.

Travelers looking for higher or longer‑lasting options can choose one of 4S eSIM’s fixed data plans, such as the Guam 20GB - 30 days plan or the Guam 10GB - 5 days plan. These plans give a fixed amount of data for a fixed validity period and are generally more cost‑effective unless a user requires continuous live‑streaming or other heavy daily usage.

4S eSIM does not offer a Guam eSIM that includes a phone number or SMS capability. Only data‑only plans are available from this provider. Travelers who need voice and messaging can usually rely on popular VoIP apps such as WhatsApp, Telegram, and iMessage over the data connection, but it is advisable to confirm that these services are accessible in Guam before purchasing, as some destinations may block or restrict specific apps.

4S eSIM provides 30 single‑country data plans for Guam, with no multi‑country options available. The plans vary from $11.34 to $229.16 and offer data caps between 714 MB and 20 GB. Among them there are 4 daily data cap plans, which reset every day, and 26 fixed data cap plans that provide a set amount of data for the entire validity period. The overall price range and data cap range give users a broad selection of choices suited to short visits or longer stays.
