MobileSIM eSIM Data Plans for United Kingdom

MobileSIM does not provide a true unlimited data eSIM for the United Kingdom. The plans that include “Unlimited” in their names actually offer 3GB of high‑speed data per day; after this amount, the speed is throttled to 1000kbps. If a user needs unlimited high‑speed data, it is not available from MobileSIM in that destination.

Instead, MobileSIM offers fixed‑data plans that can be more cost‑effective for many travelers. For example, a 20GB plan for 30 days costs $32 and a 50GB plan for 30 days costs $80, both covering the United Kingdom. These examples illustrate the available high‑data options, but they represent only a subset of MobileSIM’s full catalog.

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.

MobileSIM offers 12 single‑country data packages for the United Kingdom and 17 multi‑country packages that include the UK. The single‑country options range from 500 MB to 20 GB and are priced between $3 and $70, while the multi‑country packages can provide up to 100 GB and cost from $15 to $185. In addition to these variations, the provider’s catalog includes both fixed data‑cap plans and daily data‑cap plans, allowing customers to choose between a set amount of data for the entire validity period or a daily‑cap structure that limits usage each day.
