MobileSIM eSIM Data Plans for United Kingdom

MobileSIM does not currently provide a true unlimited eSIM for United Kingdom customers. The plans listed under “United Kingdom Unlimited data for X days” offer 3GB of high‑speed data each day, after which the speed is reduced to 1000 kbps. These are therefore capped plans, not completely open‑ended options.

If a traveler prefers a fixed‑data plan, MobileSIM offers alternatives that might be more cost‑effective, such as a 10GB plan for 30 days at $19.50 USD, a 20GB plan for 30 days at $32.00 USD, or a larger 60GB global plan for 125 days at $165.00 USD. These plans give a higher total data allowance without a daily limit and do not throttle speed once the allocated data is used.

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 22 United Kingdom data plans, divided between 12 single‑country plans and 10 multi‑country plans. The single‑country plans feature data caps from 200 MB up to 60 GB, with prices ranging from $2.30 to $165.00 and validity periods of 3 to 125 days. The multi‑country plans cover the same price and data ranges but allow roaming across several destinations with the same United Kingdom data allotment. Some plans apply a daily data cap, limiting the amount of data you can use each day, while others provide a fixed total data allowance that can be consumed at any point during the validity period. The overall price range for all MobileSIM UK plans is $2.30 to $165.00, and the data caps span 200 MB to 60 GB.
