4S eSIM eSIM Data Plans for Guam

4S eSIM’s plans that carry the name “Unlimited” for Guam are actually capped at 3GB, 5GB, or 10GB of high‑speed data, and once the data cap is reached the speed drops to 1000kbps. This means that 4S eSIM does not provide a truly unlimited‑data eSIM for Guam, where data could be used without any restriction. Travelers who need more data can opt for a fixed‑data plan instead; for example, the Guam 20GB – 15 days plan offers 20GB of high‑speed data over fifteen days, and the Guam 10GB – 5 days plan gives 10GB of data for five days.

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.
