Simology eSIM Data Plans for Guernsey

Simology does not provide a fully unlimited high‑speed eSIM plan for Guernsey. All plans that carry “Unlimited” in their name give 1GB of full‑speed data per day for the number of days stated (for example, 3 days, 5 days, up to 30 days). After that daily quota is reached, the speed drops to 1 Mbps, so the data is technically unlimited but at a throttled speed.

If a traveler prefers a larger data allowance that stays at full speed, Simology offers fixed data plans such as the 50 GB plan for 30 days at $53.50 USD or the 20 GB plan for 30 days at $34.89 USD. These fixed plans keep the data speed unthrottled for the entire validity period.

Simology does not provide Guernsey eSIM plans that include a phone number or SMS capability. Only data‑only eSIM options are available for Guernsey destinations. Travelers who need voice or messaging services can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, although some destinations may block or restrict specific apps so it is advisable to verify that the services you need are accessible in Guernsey before purchasing.

Simology offers 13 single‑country data plans for Guernsey, with no multi‑country options. The plans range in price from $3.48 to $82.01 and provide between 1 GB and 50 GB of data. Some plans cap data on a daily basis, limiting usage each day, while others offer a fixed total data allowance for the entire validity period.
