I am german , now living in switzerland near to germany and have also still a german bancaccount . My problem is that I can‘t make a new account because i have a swiss phone number . And switzerlsnd is Not Supporting Pay PAL. And i have no Credit card.
Paypal is country specific so if you move countries you have to open another paypal account in the country you reside in and add an address / phone number / bank accounts / cards from within that country.
You should really withdraw any funds / resolve issues / remove cards and bank accounts / cancel any subscriptions and close the old Paypal account before you move countries. If you don't then you may have problems doing so once you have moved and may need to contact customer services for help to resolve things.
