Earth Esim offers several unlimited data eSIM plans for Guam. The plans range in price from $5.99 USD for a 1‑day plan to $55.99 USD for a 15‑day plan, and all provide unlimited data usage within the specified validity period. Each plan allows tethering and includes a maximum speed of 1000 kbps, with the possibility of speed throttling after heavy usage.
Because the plans are unlimited, the data cap is not a hard limit, but a Fair Usage Policy may apply, potentially reducing speeds after extensive use. Travelers who are concerned about speed restrictions should contact Earth Esim to confirm the typical amount of data available at normal speed and whether a Fair Usage Policy applies to their chosen plan.
