CloudOn eSIM eSIM Data Plans for United Kingdom

CloudOn eSIM does not have a truly unlimited data plan for the United Kingdom. The plans branded with “unlimited” actually provide 2GB per day of high‑speed data; once that daily quota is reached the speed is reduced to 1000 kbps.

Travelers who need more data can choose from fixed‑amount plans. For example, a 50GB data plan for 30 days is available in the United Kingdom, as are 20GB and 10GB plans for the same period. These fixed‑data options may be more cost‑effective than the capped “unlimited” plans, especially for users who are heavy data consumers.

CloudOn eSIM does not provide any United Kingdom eSIM plans that include a phone number or SMS capability. All eSIMs offered by CloudOn for the United Kingdom contain only data; there are no options for inbound or outbound voice calls or text messages.

If you need to make calls or send messages while traveling, you can use VoIP applications such as WhatsApp, Telegram or iMessage over the data connection. These services allow you to communicate without requiring a local phone number or SMS functionality.

CloudOn eSIM provides two distinct classes of plans for travelers in the United Kingdom. There are six single‑country plans that cover only the UK, enabling users to choose a data cap tailored to their local usage needs. Additionally, 18 multi‑country plans include the UK along with other destinations, offering flexibility for those who wish to stay connected while moving between countries.
The available plans span a wide pricing spectrum, from $3.99 up to $177.49, and the data caps range between 1 GB and 50 GB. Among the plans, 8 are structured around a daily data cap, limiting the amount of data available each day, while the remaining 16 use a fixed data amount that is unlocked from the start of the validity period. Both types keep an optional reduced speed mode at 1 Gbps for overloaded networks.
