Is roaming free in the UK with my EU SIM card post-Brexit, or is CheapESIM better?

Since Brexit, the UK is no longer part of the EU's "Roam Like at Home" policy, meaning roaming is NOT free for most EU SIM card holders. Many EU carriers now charge significant international roaming fees for data usage in the UK, turning a short trip into an expensive surprise. Opting for a CheapESIM plan for the UK is a savvy financial decision. You can get several gigabytes of data for a transparent, low price, avoiding unpredictable daily charges that can quickly exceed the cost of a dedicated eSIM plan. This guarantees value and prevents bill shock.
