Cellesim eSIM Data Plans for United Kingdom

Cellesim does not provide an unlimited data eSIM for the United Kingdom. The available plans are fixed data bundles, such as 50GB for 30 days, 50GB for 180 days, 20GB for 30 days, 10GB for 30 days, and 5GB for 30 days, all of which include tethering. Travelers who need more data than these bundles can purchase additional data credits, but the plans themselves are not unlimited. Choosing a fixed data plan can be more cost‑effective for most users, unless they are extremely heavy data consumers who would benefit from an unlimited option.

Cellesim does not offer United Kingdom eSIM plans that include a phone number or SMS capability. Only data‑only eSIM plans are available for this destination.

Travelers can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for calls and messaging, but some destinations may block or restrict access to specific apps or VoIP services, so it is advisable to verify that the apps you rely on are accessible in the United Kingdom before purchasing.

Cellesim’s United Kingdom catalogue contains 18 single‑country data plans and no multi‑country options. The plans vary in type: ten provide a daily data cap while eight offer a fixed data allowance. Prices start around $2.00 and can go up to $127.50, and data limits range from 1 GB to 50 GB. Validity periods span from five days up to 180 days, giving consumers a broad selection of options for different travel needs.
