I‘m from east Asia (not China), due to my study program, I will move to France next year, and then I will be switching to another EU country every year for 3 years (stay one year in each one). I'm not sure if I'll have to open a new account every time I arrive at a new country, or if there's a solution that allows me to have only one account but moving around in EU countries.
Another question, what about telephone number, is it possible to use the same telephone number?
