SparkRoam eSIM Data Plans for Guam

SparkRoam does not currently provide an unlimited data eSIM plan for Guam. Travelers who need more data can choose from several fixed‑data options. For example, a 20 GB plan valid for 30 days is available for $52 USD if used only in Guam, while the same data allowance for 30 days plus 126 additional countries costs $75 USD. A smaller 10 GB plan for 30 days is priced at $28 USD for Guam alone. Selecting a fixed data plan can be more cost effective for most users unless they are an extremely heavy data consumer.

SparkRoam does not offer any Guam eSIM plans that include a phone number or SMS capability, so travelers must rely only on data‑only options. The provider’s Guam offerings provide high‑speed internet access but do not grant the ability to make traditional voice calls or send SMS messages.

Without a local phone number or SMS service, users can still communicate in Guam by using VoIP apps such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict specific apps or VoIP services, so travelers should confirm that the particular communication apps they wish to use are accessible in Guam before purchasing a SparkRoam eSIM.

SparkRoam offers 5 single‑country data plans that include Guam and 7 multi‑country plans that include Guam among other destinations. The available plans range in price from approximately $4.00 to $83.12 USD and offer data caps between 1 GB and 20 GB.
