eSIMzio eSIM Data Plans for United Kingdom

eSIMzio does not provide a truly unlimited data eSIM for the United Kingdom. The plans that carry the word “Unlimited” in their name actually offer a 3GB/day allowance; once that limit is reached the speed is throttled to 1 Mbps.

Travelers who need more data can choose from eSIMzio’s fixed data plans. For example, a 50GB plan valid for 30 days or a 100GB plan valid for 180 days are available for the United Kingdom. These plans give a larger high‑speed data allowance and can be more cost‑effective for most users, unless a traveler expects to use data well beyond the daily 3GB limit.

eSIMzio does not provide a United Kingdom eSIM that includes a phone number or SMS capability. Only data‑only eSIM plans are available for the United Kingdom.

Travelers can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for calls and messaging. However, some destinations may block or restrict access to specific apps or VoIP services, so travelers should verify that the apps they rely on are accessible in the United Kingdom before purchasing.

eSIMzio provides 26 single‑country data plans and 58 multi‑country plans that include coverage of the United Kingdom. The plans span a price range from roughly $2 USD to $228 USD and offer data caps between 200 MB and 100 GB, with validity periods from 3 to 365 days. The single‑country options typically carry a fixed data amount, whereas the multi‑country plans often use a daily data cap that resets each day.
