Can't use App because my iPhone Operating System is only 13 and I don't have room on iPhone to upgra

[MarkMalicoat]

I'm having trouble signing in to my account and paying my bill because I can't download the App because my new phone has IOS 13 and I don't have storage sufficient to upgrade the IOS.

Is there an alternate way to sign in and pay for service (and HAVE service) without having the App?

Please call me...
