eSIMCard eSIM Data Plans for Guernsey

eSIMCard does not offer a truly unlimited high‑speed data eSIM for Guernsey. All plans that carry the word “Unlimited” in the name actually have a fixed data cap, such as 1GB or 2GB, and after the cap is reached the speed is throttled (for example to 512kbps or 2000kbps). If you need more data without a hard limit, you can choose one of eSIMCard’s large fixed‑data plans, which include options such as 200GB for 31 days or 500GB for 90 days, each with the same high‑speed network. This approach may be more cost‑effective for heavy data users.

eSIMCard does not provide Guernsey eSIM plans that include a phone number or SMS capability. The only options available from this provider for Guernsey are data‑only plans, which allow you to connect to the internet via 4G or 5G but do not support conventional voice calls or text messages.

Travelers who need to communicate can use popular VoIP apps such as WhatsApp, Telegram, or iMessage over the data connection. However, accessibility of these services can vary, and some destinations may block or restrict certain apps. It is recommended that users check the availability of the VoIP services they rely on before purchasing a plan.

eSIMCard provides 30 single‑country plans that cover Guernsey, and 119 multi‑country plans that also include the island as part of a broader coverage area. The plans vary widely in cost, with prices ranging from about $3.41 to $395.07 USD and data caps from 1 GB up to 500 GB. Some plans feature a daily data cap, meaning the amount of data allocated is available on a day‑by‑day basis, while others are fixed‑data plans where the total data allowance is provided for the entire validity period.
