AeroSims eSIM Data Plans for Guam

AeroSims does not provide a true unlimited‑data eSIM for Guam. The plans labeled “Guam Unlimited” give 2GB of high‑speed data per day; once the daily limit is reached the speed is reduced to 1000 kbps, which is not an unlimited download allowance.

Travelers can choose from fixed‑data plans that offer larger data caps for a set validity period. For example, a 20GB plan for 30 days costs $55.39 USD, and a 10GB plan for 30 days costs $29.54 USD. These fixed plans can be more cost effective for users who need substantial data while traveling in Guam.

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.
