Friends are amazing. They're even better when you can talk to them for half the price. So just pick 3 of your favourite friends' numbers (that's the tough bit) and then for £4.99 a month we'll give you 50% off everything you send them: texts, pictures, videos, the whole lot. All we ask is that your mates have UK mobile phone numbers and UK landlines. Then you can talk until you lose your voice or text until your thumbs drop off.

To set up O2 Friends call 2425 free of charge from your Pay & Go mobile phone.
