MobileSIM eSIM Data Plans for United Kingdom

MobileSIM does not offer truly unlimited high‑speed data for the United Kingdom.
The plans advertised as “Unlimited” actually provide 3GB of high‑speed data per day, after which the speed is reduced to 1000 kbps. For travelers who require a consistent high‑speed connection, MobileSIM offers fixed data plans instead, such as the 20 GB for 30 days plan or the 10 GB for 30 days plan. These fixed‑data options can be more cost‑effective, especially for heavy data users.

MobileSIM does not provide United Kingdom eSIM plans that include a phone number or SMS capability. Only data‑only eSIM options are available from this provider. Travelers can still use VoIP applications such as WhatsApp, Telegram and iMessage over the data connection to make calls and send messages, but no traditional phone number or SMS service is included.

MobileSIM offers 12 single‑country plans for the United Kingdom and six multi‑country plans. The catalogue contains both fixed data plans, where a set amount of data is provided for the entire validity period, and daily data cap options that reset each day. Prices vary from roughly $2.34 to $72.50, data caps range from 200 MB to 20 GB, and validity periods span from 3 to 60 days.
