MobileSIM eSIM Data Plans for United Kingdom

MobileSIM does not provide a true unlimited data eSIM for the United Kingdom. Plans that carry “Unlimited” in their name actually supply a fixed allowance of 3GB per day; once that limit is reached the data speed falls to 1000kbps.

If a traveler needs a larger high‑speed data allowance, MobileSIM offers fixed data plans such as the United Kingdom 20 GB for 30 days at $32 USD or the United Kingdom 10 GB for 30 days at $19.50 USD. These plans provide a clear data cap that can be cost‑effective for most users unless very heavy data consumption is required.

MobileSIM does not provide eSIM plans that include a phone number or SMS capability in the United Kingdom. Travelers can use its data‑only eSIM plans and rely on VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection, but they should verify that these services are accessible in the United Kingdom before purchasing.

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.
