Monty eSIM eSIM Data Plans for Guernsey

Monty eSIM does not provide an unlimited data eSIM for Guernsey. The available plans for the island have fixed data allowances. For example, a 20GB plan is priced at $47.50 USD for 30 days, a 10GB plan costs $23.99 USD for 30 days, and a 5GB plan is $13.50 USD for 30 days. Choosing one of these fixed‑data options can be more cost‑effective unless a user requires a truly unlimited data experience.

Monty eSIM does not provide a Guernsey eSIM that includes a phone number or SMS capability. The provider offers only data‑only plans for Guernsey. Travelers can use a data connection to run VoIP applications such as WhatsApp, Telegram or iMessage for voice and text communication in place of a phone number or standard SMS.

Monty eSIM offers five single‑country data plans for Guernsey and four multi‑country plans that include the island in their coverage. The plans range in price from about $3.99 to $66.50 and provide data caps between 1 GB and 20 GB, with validity periods from seven to thirty days. Some of the packages deliver a fixed amount of data for the entire period, while others cap the daily data usage to meet different usage patterns.
