MobileSIM eSIM Data Plans for United Kingdom

MobileSIM does not provide a truly unlimited data eSIM for the United Kingdom. All of its plans for the UK have a data cap, and the plans that carry “Unlimited” in their name actually grant 3 GB per day; once the limit is reached the speed is throttled to 1000 kbps. Travelers who need a different approach can choose from fixed‑data plans, such as the 20 GB for 30 days plan priced at $32.00 USD or the 10 GB for 30 days plan priced at $19.50 USD, which offer larger data allowances without a daily cap. These options may be more cost‑effective for users who do not consume data at very high rates.

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 for the United Kingdom and 22 multi‑country plans that include UK coverage. The single‑country offerings generally use a daily data cap model, while the multi‑country plans offer fixed data amounts. Prices for plans range from roughly $1 to $99, with data caps spanning 200 MB up to 50 GB and validity periods from 3 to 60 days.
