Saily eSIM Data Plans for Guam

Saily does not provide a genuinely unlimited high‑speed eSIM plan for Guam. The plans offered by Saily in Guam are fixed‑data packages that cover the destination and around 120 other countries. For instance, the 20GB 365 days plan costs $66.99 USD, the 10GB 180 days plan costs $56.99 USD, the 5GB 60 days plan costs $33.99 USD, and the 2GB 15 days plan costs $16.49 USD.

Plans that include “UNLIMITED” in their name, such as Global UNLIMITED 30 days, actually contain a 30GB data cap; once that limit is reached, the speed is throttled to 1024 kbps. Selecting a fixed data plan can be more cost‑effective unless a traveler requires truly unlimited high‑speed data.
