ESIM.DOG sells a range of unlimited data eSIM plans that cover Guam. The most common options are the GTA Wireless Guam Unlimited Coverage and the 5G Global Unlimited 5G packages. Prices begin at $3.34 USD for a single‑day plan and rise to about $61.18 USD for a 30‑day plan. Each unlimited plan lists the data cap as unlimited, but indicates that speeds may be throttled: the GTA Wireless plan caps maximum speed at 1000kbps, while the 5G Global plan limits maximum speed to 384kbps.
Because these plans are subject to a fair usage policy, heavy data usage may reduce speeds after a certain threshold. If a traveler wants to confirm how long normal speed remains available after significant usage or would like details about the specific FUP limits, they should contact ESIM.DOG directly to verify the policy for the Guam coverage.
