MobileSIM eSIM Data Plans for United Kingdom

MobileSIM does not offer a truly unlimited data eSIM for the United Kingdom. All plans that include “Unlimited” in their name actually provide 3 GB per day and reduce the speed to 1000 kbps once that daily limit is reached. For travelers who need more data without speed throttling, MobileSIM offers fixed‑data plans such as the 20 GB plan valid for 30 days or the 10 GB plan also valid for 30 days. Choosing a fixed data plan may be more cost‑effective unless the user is an extremely heavy data consumer.

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.
