nextSIM eSIM Data Plans for United Kingdom

No, nextSIM does not supply a true unlimited data eSIM for the United Kingdom. All plans that include “Unlimited” in their name actually provide a fixed amount of high‑speed data – typically 1 GB per day – after which the connection speed drops to 512 kbps or 2000 kbps. Because of that cap, the plans cannot be classified as offering unlimited, high‑speed data.

Travelers who need more data can choose one of nextSIM’s fixed‑data options. For example, the 100 GB eSIM plan lasts 30 days at $78.65 USD, or the 50 GB eSIM plan lasts 30 days at $40.33 USD (the 50 GB 30‑day plan is also available under other branding at $48.60 USD). These fixed‑data plans provide a larger data allowance without the post‑cap speed reduction and can be more cost‑effective for heavy users.

nextSIM does not provide an eSIM plan for the United Kingdom that includes a phone number or SMS capability. The only options available from nextSIM for travelers to the United Kingdom are data‑only plans, with no inbound or outbound voice or text services attached.

If you need to make voice or text communications while abroad, you can use popular VoIP applications such as WhatsApp, Telegram or iMessage over the data connection. These services will work on any data‑only eSIM plan you purchase from nextSIM.

nextSIM lists 50 single‑country data plans and 44 multi‑country plans that cover the United Kingdom. The provider offers both fixed‑data‑cap plans, where a set amount of data runs for the entire validity period, and daily‑data‑cap plans, which reset the data allowance each day. Across all plans the price ranges from about $1.68 to $1,282.64, and the data limits run from 1 GB up to 100 GB.
