eSims are rapidly evolving and the past topics info. is a bit dated now. I think occasionally we may need ability to make calls, not just text with a data-only plan eSim added to my Galaxy S22. Last week of the trip will be in Switzerland, so would want coverage there in addition to Spain.
Past posts seemed to recommend Orange if you want both calls and data, which gives you a France-based phone number. At Google Store, the Orange app, though shows LOTS of (maybe only?) 1 star reviews where the activation never did work but you were out the cash. Then there are lots of 5 star reviews that every single one is obviously spam saying things like "I am beautiful and well balanced" rather than any comment on the app. I would be a little more comfortable with something you can install in USA and know it should work/activate as soon as connecting to Spanish cell towers. Not having another errand when jetlagged on arrival is also a nudge to do this stateside.
Have others had tons of problems with Orange like the legit reviews suggest, and if so what alternative so you recommend if you want calls as a function?
Lastly any instructions on how to make sure my Tmobile Sim is turned off from trying to connect, getting roaming fees, etc. while using only the new eSim is appreciated-- I'll be brand new to this dual sim deal.
