How long after I pay my phone bill will my phone work?

Unfortunately, if We do not receive payment within two calendar days of the date of that reminder, We may suspend the Service and/ or add a late payment charge, to cover Our reasonable costs, to Your next bill by way of compensation to Us for breaking the terms of this Agreement.

If your account is Suspended: It can take up to a half-hour to an hour for the phone(s) to be turned back on after payment, though it is usually faster than that.
