eSimfly eSIM Data Plans for Guam

eSimfly does not provide a truly unlimited high‑speed data plan for Guam. The plans that carry the name “Guam Unlimited” actually allow only 3 GB per day of high‑speed data and then throttle the speed to 1000 kbps. For travelers who need more data without throttling, eSimfly offers fixed‑data options such as a 20 GB plan for 30 days and a 30 GB plan for 30 days. Choosing one of these fixed‑data plans can be more economical unless a user consumes large volumes of data beyond the daily 3 GB limit.

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.
