GulfData eSIM Data Plans for Guam

GulfData does not offer a truly unlimited data eSIM for Guam. The plans that carry the “Unlimited” label actually provide 1 GB of high‑speed data per day, after which the speed drops to 512 kbps.
Instead, GulfData offers fixed data plans that give larger up‑to limits with constant speed, such as the Guam 20 GB – 30 days plan or the Guam 10 GB – 30 days plan. These keep full speed for the entire data amount within the validity window and can be more cost‑effective unless the traveler expects to use data beyond those caps.

GulfData does not provide an eSIM for Guam that includes a phone number or SMS capability. The provider’s offerings for Guam are limited to data-only plans, so users will not receive inbound or outbound voice or text services with the eSIM.

Travelers who need to place calls or send messages can use popular VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection. However, access to these apps can sometimes be restricted or blocked in Guam, so it is advisable to confirm that the particular services required are available before purchasing a data-only plan.

GulfData offers twenty distinct data plans that include Guam. Internally, the catalogue splits these into ten single‑country plans dedicated solely to Guam and ten multi‑country plans that bundle Guam with other destinations. The provider’s price range for these Guam‑accessible plans is roughly $6.00 to $197.50, while data caps vary from 1 GB up to 20 GB and validity periods stretch from 1 day to 365 days. In addition to the standard fixed‑data‑cap offerings— where a single amount of data is available for the entire validity period— GulfData also offers daily‑cap plans that reset a daily data allowance; customers can choose between these broader options depending on their usage pattern.
