Opinions about Knowroaming eSIM

This is the second time I have used Knowroaming as a roaming solution. Used their SIM sticker product and it is very convenient.


Great concept but difficult to use. This app makes traveling much easier, except for the annoying activation process (which takes forever). The home page of this app looks like a real Apple 2020 app… but when you want to check your plan or load funds into your account… it looks and feels like a 1999 app all of a sudden. They are so obscure and I have no idea what I should do? And, WHAT does “load balancing” mean, is it even correct grammar?

I’m not sure why this app was released if there are no SIM stickers available. Without one you can’t register.
