RoameSIM eSIM Data Plans for United Kingdom

RoameSIM does not provide a truly unlimited data eSIM for the United Kingdom. Plans that carry the label “Unlimited” give a hard cap of 3GB per day or 5GB per day, after which the speed is reduced to 1 Mbps.

Travelers who need more data can choose from RoameSIM’s fixed data plans, such as the Europe – 100 GB – 180 days plan or the Europe – 50 GB – 30 days plan. These plans offer large data allowances for a set validity period and can be more cost‑effective unless a user requires continuous, unlimited high‑speed data.

RoameSIM does not provide United Kingdom eSIM plans that include a phone number or SMS service. The provider offers only data‑only eSIMs for this destination. Travelers who need voice or messaging can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, though it is advisable to confirm that these services are accessible in the United Kingdom before committing to a purchase, as some destinations may block or restrict specific apps.

In the United Kingdom, RoameSIM offers 15 single‑country plans and 43 multi‑country plans. These plans include both fixed data cap options, ranging from about 500 megabytes up to 100 gigabytes, and daily data cap options. Prices span roughly $3.44 to $437.50, with validity periods from 3 to 365 days.
