AeroSims eSIM Data Plans for Guam

AeroSims does not provide a true unlimited data eSIM for Guam. All plans that carry the name “Guam Unlimited” are actually fixed allowance plans with a 1GB per day cap, so they limit the amount of high‑speed data that can be used during the validity period.

If you need more data, AeroSims offers fixed data plans such as the 20GB, 10GB, and 5GB options valid for 30 days on Guam. These plans grant larger high‑speed data allowances and may be more cost‑effective for travelers who require substantial data usage.

AeroSims does not provide a Guam eSIM that includes a phone number or SMS capability. Travelers can only access a data‑only plan from this provider.

Instead of an on‑cell phone number, users can rely on VoIP services such as WhatsApp, Telegram, or iMessage to make and receive calls and send messages over the data connection. However, some destinations may block or limit specific apps or VoIP services, so travelers are advised to verify that the applications they need will work in Guam before purchasing.

AeroSims offers eleven single‑country data plans and four multi‑country data plans for Guam. The plans vary in price from roughly $4.48 to $106.72 and provide data caps between 1 GB and 20 GB, with validity periods ranging from 1 to 30 days. Among these options, nine plans feature a fixed data amount, while six plans impose a daily data cap.
