eSimfly eSIM Data Plans for Guam

eSimfly does not provide a truly unlimited data eSIM for Guam.
All plans that carry the word “Unlimited” actually offer 3GB per day and, once that limit is reached, the data is throttled to 1000 kbps. For travelers who want higher data volumes, eSimfly sells fixed data plans instead. Examples include the 30 GB 30 days plan for Guam, the 20 GB 30 days plan, and a 10 GB 30 days plan. These plans give a fixed amount of high‑speed data without any daily cap, allowing users to choose an option that fits their data usage needs.

eSimfly offers a Guam eSIM plan that includes a phone number and SMS capability. The Orange World 20 GB 30 days plan costs $33.96 USD, provides 20 GB of data, and is usable for 30 days. The phone number uses the dialing code +33, which is a French number rather than a local Guam number. The plan supports inbound and outbound voice calls and inbound and outbound SMS messages. Users are encouraged to confirm the exact features and any restrictions directly with eSimfly before purchasing.

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.
