Your first bill seems to be higher as in your first month of connection you pay a month in advance with a pro rata’d balance. This happens on every network with a phone agreement.


What is pro rata?


A pro rata’d allowance is where your tariff cost is not billed in full due to your date of connection.


For example if your tariff cost was £40.00 + vat and you connect on the 15th of the month you will not be billed for the full £40.00 for your pro rata’d cost you would approximately pay lets say £20.00 along with your month in advance which would total your bill to be £60.00 + vat.
