MobileSIM eSIM Data Plans for United Kingdom

MobileSIM does not provide a truly unlimited data eSIM for the United Kingdom. The plan titled “United Kingdom Unlimited data for 10 days” actually offers 3GB of high‑speed data each day; once that threshold is reached the speed is throttled to 1000kbps. Because the data cap is specified, this plan cannot be considered unlimited in the usual sense.

If a traveler prefers a high‑data‑allowance plan without daily limits, MobileSIM offers several fixed‑data options for the UK. For example, the “United Kingdom 20 GB for 30 days” plan is priced at $32. 00 USD, and the “Europe 50 GB for 30 days” plan covers the UK as well as 41 other European countries for $80.00 USD. These fixed‑data plans may prove more cost‑effective for users who need consistent high‑speed data without the daily limit and speed reduction inherent in the “Unlimited”‑named plans.

MobileSIM does not offer eSIM plans for the United Kingdom that include a phone number or SMS capability. All eSIMs sold by MobileSIM for the UK are data‑only, so travelers would need to rely on data‑based applications such as WhatsApp, Telegram, or iMessage for voice and messaging needs.

The mobile provider has seven single‑country data plans available for the United Kingdom and an additional seventeen multi‑country plans that include UK coverage. Some of the UK‑specific plans are daily‑data‑cap packages, while the rest use a fixed data amount. Across the board, the available packages range from approximately $3.00 to $185.00 and provide 500 MB to 100 GB of data for validity periods between 3 and 365 days.
