I just wanted to make people aware if they are approaching an upgrade from O2 to try calling O2 retentions. Last year I was offered the Discount 500 tariff, 500 x-net minutes for £25p/m on a 12 month contract. I was also given the Sony Ericsson K750i.
I called them again today (my upgrade is due). I was offered a choice of new phones, 400 mins anytime any network, 300 texts for £17.50 per month, on a 12 month contract.
Plus for 6 months I get to have free calls (not from my minutes) every Sat, Sun and Mon !!
There are others who have been offered better deals too.
Call them free 08000288151. As long as you say you have looked at other networks with better tariffs.
