GlobalesIM does not provide an unlimited data eSIM for Guam. All of its plans for Guam have fixed data caps, with the largest bundle offering 10 GB of data that is valid for 30 days. Travelers who need a larger data allowance can choose one of these fixed bundles; for example, the 10 GB plan costs $85.00 USD and lasts 30 days, while a 5 GB bundle is available for 21 days at $40.00 USD. Selecting a fixed data plan can be more cost‑effective for most users unless they foresee using an extremely high amount of data.
Yes, GlobaleSIM supplies eSIM plans for Guam that include a local phone number and SMS functionality. The available plans range from 1 GB of data for 7 days at $10.00 USD up to 10 GB of data for 30 days at $85.00 USD, with intermediate options of 2 GB for 10 days, 3 GB for 14 days, and 5 GB for 21 days. All these plans use the dialing code +1 and provide both inbound and outbound voice calling.
Because the SMS feature is inbound only, users can receive text messages but cannot send them. The plans allow incoming and outgoing calls, so travelers can both receive and make calls using the local Guam number. For specific usage requirements or to confirm the latest conditions, it is recommended that users contact GlobaleSIM directly.
