Horizon eSIM eSIM Data Plans for United Kingdom

Horizon eSIM does not provide an unlimited data eSIM for the United Kingdom. All of its UK‑specific plans have a hard data cap, the largest available being 50 GB for 180 days.

If you need a sizeable data allowance, Horizon eSIM offers fixed data plans such as the United Kingdom 50GB 180Days plan at $30.18 USD or a smaller United Kingdom 20GB 30Days plan for $12.76 USD. Choosing a fixed data plan can be more cost‑effective than an unlimited option, unless you are an extremely heavy data user.

Horizon eSIM does not offer any United Kingdom eSIM plans that include a phone number or SMS capability. Only data‑only eSIMs are available for travel to the United Kingdom. Travelers can use popular VoIP apps such as WhatsApp, Telegram, or iMessage over the data connection for calls and messaging, but they should confirm that these services are accessible in the United Kingdom before purchasing a plan.

Horizon eSIMlists seven single‑country data plans for the United Kingdom and twelve multi‑country plans that also cover the UK. The available plans span a price range from $0.31 to $309.01 and a data capacity from 100 MB up to 100 GB, with validity periods from seven to 365 days. Some plans feature fixed data amounts, while others apply a daily data cap, and many of the plans allow tethering.
