eSimfly eSIM Data Plans for Guam

eSimfly does not offer a truly unlimited data eSIM for Guam. The plans labeled “Guam Unlimited” provide a daily data allowance of 3 GB; after the daily quota is reached the speed is reduced, so the high‑speed data is not unlimited.

Travelers who need more data can consider eSimfly’s fixed‑data options such as the Guam 20 GB 30‑day plan for $58.16 or the Guam 10 GB/Day plan for $29.25. These plans give a large block of high‑speed data and may be more economical than the daily‑based “Unlimited” plans for users who do not require very heavy data usage.

eSimfly does not provide an eSIM for Guam that includes a local phone number or SMS capability. Only data‑only eSIM plans are available for this destination.

Travelers who need to make calls or send messages can use VoIP applications such as WhatsApp, Telegram, or iMessage, which operate over the data connection provided by the eSIM.

eSimfly offers 11 single‑country plans that cover Guam alone and 4 multi‑country plans that include Guam as part of a broader network, making a total of 15 data plan options. Prices span from $3.98 to $96.93, while data caps range from 1 GB to 30 GB. Within this set, some plans provide a fixed data amount, whereas others feature a daily data cap, giving travelers flexibility based on their usage preferences.
