RoameSIM eSIM Data Plans for Guernsey

RoameSIM does not provide an unlimited‑data eSIM for Guernsey. The available plans are fixed data bundles with caps of 5GB, 10GB, or 20GB, each valid for a set number of days. Travelers who need more data can choose larger bundles, such as the 20GB plan valid for 30 days or the 10GB plan valid for 180 days, which give access to 5G coverage in Guernsey and many other countries. Selecting a fixed data plan can be more economical for most users, unless a very high data consumption is anticipated, in which case a higher‑capacity bundle might be preferable.

RoameSIM does not provide an eSIM for Guernsey that includes a local phone number or SMS capability; only data‑only plans are offered for that destination. Travelers who need voice or text can use internet‑based services such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict access to specific apps or VoIP services, so it is advisable to verify that the applications the traveler relies on are accessible in Guernsey before purchasing a plan.

RoameSIM offers nine multi‑country data plans that include coverage in Guernsey, with prices ranging from $10.00 to $182.81 and data caps from 1 GB up to 20 GB. The plans are mostly fixed‑data packages, and the package list also indicates that tethering is allowed on some of the options. No single‑country-only plans are currently available for Guernsey.
