Simfinity eSIM Data Plans for Guam

Simfinity does not offer an unlimited data eSIM plan for Guam. All plans listed for Guam are fixed‑amount data packages, the largest of which provides 20 GB for 30 days at $86.80 USD. A 10 GB option is also available for 30 days at $52.50 USD. These plans—together with the smaller 5 GB, 3 GB, and 1 GB options—cover 3G, 5G, and LTE networks across Guam.

Choosing a fixed data plan can be more cost‑effective for most travelers unless their usage exceeds the highest available allowance; in that case, No‑unlimited plans would require purchasing multiple packages or switching providers.

Simfinity does not offer a Guam eSIM that includes a phone number or SMS capability; only data‑only plans are available from this provider.

Travelers who need to communicate can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for calls and messaging without requiring a separate phone number or SMS service.

Simfinity offers five single‑country data plans for Guam, ranging from 1 GB to 20 GB and priced between $9.20 and $86.80 USD. The validity of each plan spans 7 to 30 days and plans are structured either as a fixed data amount or as a daily data cap where applicable, all allowing tethering. No multi‑country plans are available for Guam through Simfinity.
