My opinion is that this is not right. Its not simply a matter of semantics (and to be honest, the issue is not so overwhelming for me that I am contemplating suicide or taking o2 to court). Its just a matter of correctness & professionalism.
They have sold a sim card because of its 4G capabilities. Not because it simply works as a sim card to send and received calls/texts.
The phone I have in its current state (which I made clear to them on the phone "I didnt buy the phone from O2, but it is the samsung S4 which is capable of 4G") is not capable of using the capabilities they advertised at point of sale (i.e. the whole premise of the upgrade was its 4G). Therefore, they have missold a service, especially since they (collectively, perhaps NOT the operative who sold me the contract) knew only phones bought FROM O2 will work straight off the bat.
Think some of you are massively obssessed with O2 to concede they are in the wrong here. I myself like O2, have been with them for many years for a few reasons. But for someone in London, I actually think Vodafone are better value since they give spotify for free (which is a yearly saving of £120 if you pay for premium now). However my contract wasnt up yet, and I wanted 4G, so I bit the bullet with o2 - without buying out the rest of my contract.
