MobileSIM eSIM Data Plans for United Kingdom

MobileSIM does not provide a truly unlimited data eSIM for the United Kingdom. The plans that carry “Unlimited” in the name offer 3 GB of high‑speed data per day; once that daily allowance is reached the speed is throttled to 1000 kbps. Travelers who need uninterrupted data can choose from MobileSIM’s fixed‑data plans, such as the 20 GB for 30 days plan that costs $32.00 USD or the 10 GB for 30 days plan that costs $19.50 USD. Fixed‑data options avoid speed throttling and can be more cost effective for those who consume a large amount of data.

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 lists 12 single‑country data plans that cover only the United Kingdom and 21 multi‑country plans that include the UK among other destinations. The plans vary between a daily data cap structure, where users receive a set amount of data each day, and a fixed data cap structure, where a total amount of data is delivered for the validity period. Across all plans, prices range from about one to eighty dollars and data caps span from 200 megabytes up to fifty gigabytes.
