Apple Music Subscription

Hello, I would like to ask something here and its about apple music subsription. Before I got the billing address for payment, I didn’t notice that i haven’t changed my payment method. So, the billing was charged to my old phone number and now i just changed it which is my latest phone number at payment method. So, how can i pay for it? Because the old number is not activate anymore. Will i get the new billing address or what? Thank you!
