eSIM.net

eSIM.net is UK-founded and operated, which shows in its product. You get voice, SMS, and data all in one plan, unlike some competitors who only offer data. If you need to stay reachable on your UK number while in Europe, they offer EE-backed plans with a UK phone number included, useful for banking alerts or work calls.

The full communication suite (voice, SMS, data) appeals to business travellers or anyone who needs to maintain reliable contact channels abroad. The integration of UK continuity through EE is a thoughtful feature for British travellers who'd otherwise lose their main number while travelling.
