eSIMzio eSIM Data Plans for United Kingdom

eSIMzio does not provide a truly unlimited data eSIM for the United Kingdom. All plans that carry the word “Unlimited” in their name actually have a daily data cap of 3GB; once that limit is reached the speed is throttled to 1000kbps.

Instead, eSIMzio offers fixed‑data plans that give larger, unthrottled data allowances. For example, the United Kingdom 50GB plan is valid for 30 days and costs $45.39 USD, while the Europe 100GB plan is valid for 180 days and costs $214.08 USD. These plans can be more cost‑effective for travelers who need a substantial amount of data without the daily cap.

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 47 multi‑country data plans that cover the United Kingdom. The plans are offered in two main styles: daily data‑cap plans give a set amount of data that is reset each day, while fixed data‑cap plans give a total data allotment that lasts for the entire validity period. Prices on the platform range from around $2.03 to $228.30, and the data caps available span from 200 MB up to 100 GB.
