Esimatic eSIM Data Plans for Guernsey

Esimatic does not offer any unlimited-data eSIM plan for Guernsey. Instead, it provides fixed‑data plans that are suitable for most travelers. For example, a 100GB plan valid for 30 days costs $168.81 USD, and a 50GB plan valid for 30 days costs $103.68 USD. These larger‑allowance options tend to be more cost‑effective unless a user requires extremely high data consumption, in which case a higher‑capacity plan may be preferable.

Esimatic does not offer a Guernsey eSIM that provides a local phone number or the ability to send or receive SMS. Travelers who use an Esimatic plan in Guernsey will have only data‑only access. The data connection can still support VoIP services; popular apps such as WhatsApp, Telegram and iMessage generally work over the data link for calls and messaging. However, some destinations may block or restrict specific VoIP apps, so users should verify that the services they rely on are available in Guernsey before purchasing a plan.

Esimatic provides 28 single‑country plans that cover Guernsey, alongside 20 multi‑country plans that include Guernsey as part of a larger zone. The plans vary in price from about $4.49 to $325.10 and offer data caps ranging from 1 GB up to 100 GB, with validity periods between one and thirty days.

Some plans use a daily data cap, limiting the amount of data usable each day, while others use a fixed data cap that applies to the entire validity period. This gives travellers flexibility depending on whether they need a consistent daily allowance or a larger total data pool.
