Hiroaming eSIM Data Plans for Guam

Hiroaming does not provide an unlimited data eSIM for Guam.
Instead, Hiroaming offers fixed‑data plans that require the data to be used within a set number of days. Examples include the Guam 20GB 30Days plan, which costs $75.42 USD and is valid for 30 days, and the Guam 10GB 30Days plan, priced at $40.22 USD for the same period. These fixed‑data options are generally more cost effective for most travelers, unless a user is an extremely heavy data consumer.

Hiroaming currently does not offer a Guam eSIM that includes a phone number or SMS capability. travelers using Hiroaming for Guam can only purchase a data‑only plan.

Although no phone number is provided, a data connection can be used with VoIP and messaging apps such as WhatsApp, Telegram, and iMessage. Because some destinations sometimes restrict or block specific apps or services, travelers should confirm that the apps they intend to use are accessible in Guam before purchasing a plan.

Hiroaming provides 12 single‑country data plans for Guam, with no multi‑country options available. The plans cover data caps ranging from 500 MB up to 20 GB, and prices start around $4.52 and go up to about $75.42. Some plans are offered as fixed data bundles, while others let you use data within a daily allotted amount, giving travelers flexibility depending on how long they stay.
