Vodaphone charges high tariff for less minutes and does not allow VOIP. Recently my company changed to O2 from vodaphone. Now I get 30% discount through O2 Open on their already better rates than Vodaphone. O2 rewards brand loyality unlike vodaphone which is only interested in milking customers.Plus O2 got IPhone as well.
I rebranded my Vodaphone branded N95 8gb, which I bought on ebay to use on Three UK as it gives free skype calls making international calls free. Either vodaphone should be more competitive and customer focused or sell its core business and exit.
