abesteSIM eSIM Data Plans for Guam

abesteSIM does not provide an unlimited data eSIM plan for Guam. The available options are fixed‑data plans, such as the 30GB eSIM Guam – 30 days, priced at $51.61 USD, and the 20GB eSIM Guam – 30 days, priced at $37.19 USD. These plans include tethering, a reduced speed of 128 kbps, and coverage on 5G networks within Guam. For travelers who do not require exceptionally high data volumes, a fixed‑data plan can be a more cost‑effective choice, while heavy data users might need to consider supplementary options.

abesteSIM only sells data‑only eSIM plans for Guam; the provider does not provide a phone number or SMS capability with any of its Guam offerings.
Travelers who need voice or text can use compatible VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, though they should confirm that such services are not blocked or restricted in Guam before making a purchase.

AbesteSIM offers 38 single‑country data plans for Guam. The plans span a price range of $4.41 to $233.50 and provide data caps between 500 MB and 30 GB. Within its catalogue, the provider includes 53 plans that use a daily data cap and 27 plans that use a fixed data cap, giving customers the option to choose between a limit that resets each day or a single total data allocation for the validity period.
