eSIMzio eSIM Data Plans for United Kingdom

eSIMzio does not provide a truly unlimited data eSIM for the United Kingdom. All of its United Kingdom‑specific plans have a hard data allowance that is capped each day, and after the daily limit is reached the data speed is reduced to 1 Mbps. For example, the United Kingdom Unlimited — 7 days plan gives 3 GB of high‑speed data per day and throttles after that, while the Europe Unlimited — 7 days plan, which also covers the UK, provides 5 GB per day before speed is reduced.

Travelers who need more data have access to large fixed‑data plans such as the United Kingdom 50 GB over 30 days or the Europe 100 GB over 180 days. These plans offer higher total data amounts and no daily throttling until the overall cap is reached, making them more cost‑effective for heavy data users.

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 offers 26 single‑country plans and 53 multi‑country plans for the United Kingdom. The available plans span a price range of roughly $2.03 to $228.06 and provide data caps from 200 MB up to 100 GB. Some plans are fixed‑data‑amount plans, giving a set amount of data for the entire validity period, while others use a daily data cap that resets each day. A few plans also allow tethering and have a reduced speed of 1000 kbps.
