eSIM Cards eSIM Data Plans for United Kingdom

eSIM Cards does not offer a truly unlimited data eSIM for the United Kingdom. The plans labeled “Unlimited” under eSIM Cards include large data caps of 1, 024GB, 750GB, or 1, 000GB and note that speed may be throttled after the cap is reached, so they are not unlimited in the sense of a no‑limit high‑speed allowance.

If you need a fixed data plan, options are available such as the UK Three 500GB plan for 30 days priced at $31.01 USD and the UK Vodafone 200GB plan for 30 days priced at $34.31 USD. These plans provide a set amount of high‑speed data and can be more cost‑effective unless your usage exceeds those limits.

eSIM Cards does not provide United Kingdom eSIM plans with a phone number or SMS capability; all available UK eSIM options from this provider are data‑only plans. Customers can use the data connection for internet access but cannot make or receive standard voice calls or send or receive SMS messages through the cellular network.

If callers need to communicate while traveling, popular VoIP applications such as WhatsApp, Telegram, and iMessage can be used over the data connection. These apps provide voice call and messaging functionality without requiring a local phone number or SMS service.

The eSIM Cards provider lists eight single‑country data plans and six multi‑country plans that include the United Kingdom. In the single‑country set, the plans are all UK‑only and can be purchased for a price between $19.79 and $34.31, with data allowances ranging from 25 gigabytes up to 1, 024 gigabytes for 30 days. The multi‑country plans allow usage across the UK and other destinations; they also fall within the same price range and data ranges, with the same 30‑day validity. For both categories, some plans permit tethering, though the speed may be throttled after the data cap is reached.
