What is ‘pro rata’ billing?
Your mobile subscriptions are paid for in advance and invoices are based on the 1st of every month. On a connection’s first invoice, or first invoice after a tariff change, there will often be some pro rata billing.
Example
First invoice - If your monthly line rental is £10.00pcm and your subscription is connected on the 15th of the month, you will receive an initial bill of the 15 days until the end of the month, as well as the full rate for the following month. Making that bill total £15.00. Your next bill will not be due until the 1st of the month following.
