iPhone 4 unlimited o2 to o2 calls

[leemkule]

Alright, well I've looked pretty extensively but I'm completely confused with all the information available, is there any way that I can get unlimited o2 to o2 calls with an iPhone 4 without paying like £60-£75 a month? I'm not all that bothered about the limits on other aspects such as data/texts.

Any help would be appreciated.

you have eiher 2 options.

Their are 2 bolt on you can add.

Their is family bolt on which cost extra £7.50 a month which upto 5 family friends on 02 calls and text are free.

And another bolton on with unlimited 02 calls..need to check the 02 website for more details of that or you can call up customer service.
