MobileSIM eSIM Data Plans for United Kingdom

MobileSIM does not provide a truly unlimited high‑speed data eSIM for the United Kingdom. All plans that carry “Unlimited” in the title actually offer 3GB per day and reduce speed to 1000 kbps once the daily limit is reached, so the data is capped rather than unlimited.

If you need a larger data pool you can choose one of the fixed‑data plans instead. For example, MobileSIM offers a 20 GB plan valid for 30 days priced at $32.00 USD and a 50 GB plan for 30 days priced at $80.00 USD. These fixed‑data options can be more cost‑effective for travelers who consume large amounts of data but do not require maintenance of the highest speeds once the allocation 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 12 single‑country data plans for the United Kingdom and 16 multi‑country plans that include the UK. The catalogue lists prices between about $1 and $80, data allowances ranging from 200 megabytes to 50 gigabytes, and validity periods from 3 to 365 days. In addition to the standard fixed‑data plans, seven daily‑cap options are available; these reset the data quota each day rather than providing a single total amount.
