nextSIM eSIM Data Plans for United Kingdom

nextSIM does not offer a truly unlimited high‑speed data plan for the United Kingdom. All of the plans in their “Unlimited” line provide 1GB per day of high‑speed data; once the 1GB cap is reached the speed drops to 512kbps (for Standard) or 2000kbps (for Plus). Because the speed is throttled after the limit, the plan is not considered unlimited by standard definition.

For travelers who need more than 1GB of high‑speed data, nextSIM has fixed‑data options. An example is the 100GB plan for 30 days, priced at $76.32, or the 50GB plan for 30 days, priced at $23.91. These plans give the user a larger amount of high‑speed data before any throttling occurs and can be more cost effective for heavy data users.

NextSIM does not provide a United Kingdom eSIM that includes a phone number or SMS capability. All United Kingdom plans from nextSIM are data‑only, so customers can use VoIP apps such as WhatsApp, Telegram, or iMessage to make calls and send messages over the data connection.

nextSIM offers both single‑country and multi‑country data plans for the United Kingdom.
There are 74 single‑country plans and 68 multi‑country plans available.
The plans span a price range of about $1.68 to $1, 295.18, provide data caps from 1 GB up to 100 GB, and have validity periods that can be as short as one day or as long as one year.

Fixed‑data‑cap plans grant a set amount of data that can be used at any time during the validity, while daily‑data‑cap plans reset the data quota daily, allowing continuous use but requiring the plan to be active for consecutive days.
