AeroSims eSIM Data Plans for Guam

No. AeroSims does not provide a truly unlimited eSIM plan for Guam. The plans marketed with “Unlimited” give high‑speed data at 2 GB per day and then reduce the speed to 1000 kbps once the daily allowance is used; the data cap is still a hard limit.

AeroSims offers fixed‑data options instead. For example, a 20 GB plan valid for 30 days costs $55.39 USD, and a 10 GB plan for the same period costs $29.54 USD. These plans give a larger total data allowance and may be more cost‑effective for travelers who need more than the 2 GB daily limit offered by the “Unlimited” labels.

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 for Guam and four multi‑country options that include Guam as part of their coverage. The single‑country selection ranges from 1‑day to 30‑day packages, with data caps spanning 2 GB to 20 GB. The multi‑country bundles cover the same data range but add additional regional destinations. Plans are grouped into fixed data cap models—providing a set amount of data for the entire validity period—and daily data cap models, which limit usage each day. Prices across the portfolio vary from roughly $7.77 to $210.40, reflecting differences in duration, data limits, and destination breadth.
