SimSmash eSIM Data Plans for Guam

SimSmash does not provide a truly unlimited data eSIM for Guam. All available plans list a fixed data allowance, such as 1GB, 5GB, 10GB, or 20GB, and their validity ranges from 1 day to 30 days. For travelers who require more data, a fixed data plan can be a more economical option. For example, the 20GB plan for 30 days costs $58.99 USD, and the 10GB plan for 30 days costs $31.99 USD. If a user needs a large amount of data for a single day, SimSmash also offers daily plans up to 10GB, though they remain limited to that amount.

SimSmash does not provide any Guam eSIM plan that includes a phone number or SMS capability. All eSIM offerings from SimSmash for Guam are data‑only, so they cannot be used for traditional voice calls or text messages. However, travelers can still communicate via popular VoIP applications that work over a data connection, such as WhatsApp, Telegram or iMessage, which do not require a local phone number or SMS feature.

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.
