eSimfly eSIM Data Plans for Guam

eSimfly does not provide a truly unlimited high‑speed data plan for Guam. All of its plans that carry the word “Unlimited” in the name actually offer a capped amount of data – 3GB per day for a set number of days – and the speed is reduced once that daily limit is reached. Consequently, while the plans are marketed as unlimited, they are not unlimited in the sense of providing limitless data at full speed.

Travelers who need a larger data allowance without the daily cap can choose eSimfly’s fixed‑data eSIM options. For example, a 30GB plan for 30 days is available for $62.60, and a 20GB plan for 30 days costs $44.52. Both of these cover Guam and several other territories. These fixed‑data plans may be more cost‑effective for users who consume a lot of data but do not need truly unlimited high‑speed connectivity.

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 provides 12 single‑country plans and 4 multi‑country plans for Guam. Among these packages, 11 offer a fixed amount of data while 5 are capped on a daily‑cap basis; the fixed plans give a lump sum that can be used over the validity period, whereas the daily‑cap plans limit the amount of data usable each day. The price of these Guam‑specific options ranges from about $9.89 to $142.64, with data caps from 1 GB up to 30 GB and validity periods between 3 and 30 days. Tethering is permitted on the applicable plans.
