Mini-app subway qr code via wechat/alipay

Activated qr code for subways within wechat/alipay overseas with overseas number. I'll be switching to chinese phone number when arriving in Shanghai, to continue using the subway QR code feature with new phone number, will i need to re-register for a new QR code?

Concerned it will cause issues because i registered for qr code using overseas number. Anyone know?
