thirr.com eSIM Data Plans for Guernsey

Thirr.com does not provide any unlimited‑data eSIM plans for travel to Guernsey.
Instead, the provider offers a range of fixed‑data options. For example, the EU XXL 200GB 31D plan gives 200 GB of high‑speed data for 31 days at $70.74 USD, while the EU XXL 100GB 31D and XXL World 100GB 31D plans offer 100 GB for about $47–$77 USD. Smaller plans such as EU XXL 50GB 31D ($29.47 USD) and EU PLUS 50GB 30D ($58.95 USD) are also available. These fixed plans can be more cost‑effective for most travelers, though users who require very heavy data usage might consider alternative carriers that do offer unlimited data.

Thirr.com does not provide any Guernsey eSIM plans that include a phone number or SMS capability. All Guernsey plans sold by the provider are data‑only; they do not allow inbound or outbound voice calls or text messages. Travelers who need to communicate while in Guernsey can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, which work without a traditional phone number or SMS support.
