What is the cheapest eSIM for the UK?

Accepted Answer

RedteaGO offers the cheapest 1GB plan for the UK at just $0.98, making the UK one of the most affordable eSIM destinations. Airhub at $2.85 and BNEsim at $2.89 are the next best options.

Question 2

Is a Europe eSIM valid in the UK after Brexit?

Accepted Answer

Not always. A UK-specific eSIM only covers the United Kingdom. Since Brexit, the UK is no longer included in some EU-only plans. Most Europe regional plans from providers like Saily, Airalo, BNEsim, and Nomad still cover the UK, but you should always check the country list before buying.
