Is there an eSIM company that to multiple countries or at least internationally?

I got the new iPhone and my old iPhone has been locked by t-mobile (neither apple or t-mobile will do anything about it). Its been hell; and i don’t want that to happen to my new phone. I only travel between USA and EU countries. Any recommendations?

p.s. I know you can pay someone to unlock your phone but then I would have to pay for that 8 times a year

Many thanks 🙏
