Thank you for your feedback! I wonder that too may be it is the 3g /4g /5g network thing, if it works here in the States but not in Fr.
What I am going to buy is not an actual phone chip, it is an Orange E-sim download to my Samsung. It did ask if my phone is capable to accept it. I checked, it is okay. I will try.
It is helpful with your info, thank you. Hope you find your solution.
My brother-in-law just went to Barcelona, he has iPhone, he said he needed to upgraded his phone plan with Verizon before he went, then he paid only additional $6 for international data usage; but one must need to think, it was Barcelona (big city) that worked great, what if he went off to some small cities in Spain, would he got the same good signal...not sure!!
