Cellesim eSIM Data Plans for Guernsey

Cellesim does not provide an unlimited‑data eSIM plan for Guernsey. The available options are fixed data plans that limit the amount of high‑speed data that can be used within a set number of days. For example, a 20GB plan is valid for 30 days at a price of $67.58 USD, while a 5GB plan is also valid for 30 days and costs $23.00 USD. These fixed data plans can be more economical for most travelers, though they are bound by the data cap specified in the plan.

Cellesim does not provide a Guernsey eSIM that includes a phone number or the ability to send or receive SMS. Only data‑only plans are offered for Guernsey.

Travelers who need to make calls or send messages can use VoIP applications such as WhatsApp, Telegram or iMessage over the data connection. However, some destinations may block or restrict access to these services, so it is advisable to confirm that the apps you rely on are available in Guernsey before purchasing an eSIM.
