Hello everyone, not finding information on this subject nowhere I would like to know that it is compatible with the Fairphone 5 in order to use it in Japan for a certain period?
Network bands in Japan being different I would like to know if there are E-SIM companies (Internet) compatible with Fairphone 5 (E/OS)? I can’t find any supplier mentioning the Fairphone brand.
Thank you for your future response
/e/OS works in Japan if the bands are the same as your phone. I used Mobal (Softbank), Mineo (Softbank) and Rakuten on a Pixel 4a but all of them were physical sims.
I had eSim in Switzerland working with the same device.
Hope that answers mostjof your questions.
Thank you for your answer, suddenly the fact that it is on E/OS does not change anything of what I understand.
The answer for fairphone is missing if they are compatible with the Japaneaias network bands and that it is e-sim adapted =)
You can research the bands by yourself 
.
Here are some sources for FP5:

Regarding eSim I am pretty sure it will work, since it is a worldwide standard.
Thank you for your complete information =D
