TooSim eSIM Data Plans for Guernsey

TooSim does not provide an unlimited data eSIM for Guernsey. The provider offers several fixed‑data plans that cover the island and 106 other countries. For instance, a 20GB plan valid for 30 days costs $189.99 USD and a 10GB plan for the same period costs $112.99 USD. These fixed plans can be a more cost‑effective option unless a user requires very high or unlimited data usage.

TooSim does not provide an eSIM plan with a local phone number or SMS capability for Guernsey. The available plans are data‑only; they allow roaming on cellular networks without the option to receive voice calls or text messages. Travelers can still use messaging and voice services via VoIP applications such as WhatsApp, Telegram, or iMessage, which operate over the data connection.

TooSim currently offers six data plans with coverage including Guernsey. These are multi-country plans, providing data access in several locations, not just a single country. The available plans range in price from approximately $20.99 to $189.99 and offer data caps between 1GB and 20GB. Plans have varying validity periods from 7 to 30 days. Tethering is permitted with some of the available options. Currently, TooSim does not offer single-country data plans specifically for Guernsey.
