Will I still be able to use Paym after my account switch, which I registered for with my old bank?

On your chosen switch date, your old bank or building society will de-register your mobile phone number from Paym. Then you can register for Paym in the Barclays Pingit app. You can do this on or after your switch date. If you prefer, you can de-register your mobile number at your old bank or building society yourself, and then register with us.
