Just had the most amazing phone conversation with O2. My wife has a Nokia 5800. She used to be on a "Simplicity" tarrif and wanted to upgrade to "Simplicity for Smartphones 12 months" This way her £10 per month became £15 but she got unlimited data. "That tariff isn't available" is what the O2 woman said. But we said we were looking at that tariff on screen. "That tariff isn't available to you" is what she went on to say. We asked why not, we were told we didn't have a Smartphone. We explained we did, but no, O2 do not class this phone as a Smartphone and so we cannot have the Simplicity for Smartphone deal. We were livid and were going to leave there and then. Eventually we were sold Simplicity for iPhone 12 months which offers the same deal. So we cannot buy a "for Smartphone" tariff becuae O2 don't class the 5800 as a smartphone. Yet eventually they would sell us an iPhone tariff!! Absolutley unbelievable. It shouldn't matter what phone you have, if we want to buy this tariff we should be able to. Over half an hour spent on the phone over this - crazy!
