MobileSIM eSIM Data Plans for United Kingdom

MobileSIM does not provide a truly unlimited eSIM plan for the United Kingdom. All of its United Kingdom offerings listed in the dataset are capped at 3 GB per day and carry a reduced speed of 1000 kbps once that daily limit is reached. The plans are labeled “Unlimited” in the name, but they are not unlimited high‑speed data plans.

Instead, MobileSIM offers fixed‑data eSIM options for travelers to the United Kingdom, such as a 20 GB plan valid for 30 days priced at $32.00 USD and a 10 GB plan valid for 30 days priced at $19.50 USD. These fixed‑data plans may be more cost‑effective for users who do not need vast amounts of high‑speed data or who want to avoid speed throttling after a daily threshold.

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.
