MobileSIM eSIM Data Plans for United Kingdom

MobileSIM does not provide a truly unlimited eSIM plan for the United Kingdom. All plans labelled “Unlimited” give a daily allowance of 3GB and provide high‑speed data only until that daily limit is reached; after the limit is exceeded the speed is reduced to 1000kbps.

If you need a fixed data allowance instead, MobileSIM offers several large‑capacity options for the United Kingdom, such as a 20GB plan valid for 30 days priced at $32.00 USD, and a 10GB plan valid for 30 days priced at $19.50 USD. These plans give you a predictable amount of high‑speed data without the speed reduction that appears after the daily 3GB threshold.

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 a total of 12 single‑country data plans and 21 multi‑country plans that include coverage in the United Kingdom. The plans vary between fixed data amounts—capable of offering up to 50 GB—and daily data caps, which can provide as little as 200 MB for short‑term travelers. In terms of cost, the available UK plans run from around $1.00 up to $80.00, giving a wide range of data capacities across the 200 MB to 50 GB spectrum.
