If you are a normal BT customer, from the 1st of October there will be another price rise on top of your April price rise making an overall increase of over 20% in a year 

BT price rises are :-

Monthly line rental will increase by 50p / month
Connection charge will increase from 9.9p to 10.9p
Daytime rate rises from 5.9p to 6.4p / minute.

So this means a 6 minute call will cost 6 * 6.4p + 10.9p = 49.3p a 6 minute call on GiffGaff will only cost you 48p excluding any goodybags. Any call less than 7 minutes is cheaper on GiffGaff  to normal 01,02,03 numbers. If you are calling a mobile then GiffGaff is always cheaper.

With GiffGaff there is no monthly line rental BT will rise to £12.04 per month.

Use GiffGaff and start saving your money - tell your BT mates and give them a GiffGaff sim.
