SimSmash eSIM Data Plans for Guam

SimSmash does not provide a truly unlimited data eSIM for Guam. The plans that carry “Unlimited” in their name actually offer a fixed amount of high‑speed data each day; for example, the “Guam Daily Unlimited 1GB/day” plan supplies 1GB of high‑speed data for one day. After the allotted data is used, the connection speed is reduced.

Instead, travelers can choose fixed data plans that give a larger data allowance over a longer validity period, such as the “Guam 20GB for 30 Days” plan or the “Guam 10GB for 30 Days” plan. These plans provide a higher amount of data for a full month, which may be more cost‑effective for most users, especially those who need more than 1GB of data in a single day.

SimSmash does not provide a Guam eSIM that includes a phone number or SMS capability. Travelers who purchase a SimSmash eSIM for Guam will receive only a data‑only plan. They can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for voice and messaging, but they should verify that these services are accessible in Guam before buying, as some destinations may block or restrict certain apps.

SimSmash offers 11 single‑country plans and 7 multi‑country plans for Guam, giving a total of 18 different data options. The plans cover a price range from $3.79 to $67.99 and provide data caps that vary from 490 MB up to 20 GB. These plans may include features such as tethering, depending on the specific offering.
