iRoamly eSIM Data Plans for Guernsey

iRoamly does not provide a truly unlimited data eSIM for Guernsey. All of the available plans labeled “Unlimited” actually contain a 500GB high‑speed data allowance. Once this amount is reached the speed would be throttled, though the specific reduced speed is not listed in the data.

Instead, iRoamly offers a range of fixed‑data plans that can be chosen based on how long a traveler will stay in Guernsey. For example, a 500GB plan can be purchased for 1 day at $18.50 USD, for 5 days at $89.00 USD, or for 10 days at $178.00 USD. These plans include tethering where specified. Choosing a fixed‑data plan may be more cost‑effective than a higher‑price unlimited offering for most users.

iRoamly does not offer a Guernsey eSIM plan that includes a local phone number or SMS capability. The provider sells only data‑only plans for the island. Travelers who need to make calls or send messages can use VoIP apps such as WhatsApp, Telegram, or iMessage over the data connection.

iRoamly offers 68 single‑country data plans that cover Guernsey and 2 multi‑country plans that include Guernsey as part of a broader network. The available plans range in price from free to about USD 534 and in data from 500 MB up to 500 GB, with validity periods between 1 and 30 days. In addition to normal data packages, iRoamly provides 21 daily data cap options—where users receive a specified amount of data each day—and 49 fixed data cap options, which give a set amount of data for the entire validity period. The combination of single‑country and multi‑country choices, along with both daily and fixed data cap options, gives travelers a wide variety of pricing and data restrictions to meet different usage needs.
