I bought an iPhone from Carphone Warehouse as a SIM FREE device as I already had a contract with EE. I have since moved and EE do not have coverage so I have entered into a new contact with O2. On placing the O2 SIM into my SIM FREE device I now discover that the phone was locked to the EE network. They do not and have never owned my phone. What gave them the right to lock my phone which I had purchased outright from a different company. That is theft. Well, I discovered that it was not EE who have instigated this, but the Software that Carphone Warehouse load on their SIM FREE phones that automatically lock your device to the first SIM you use. This is a feature developed and implemented by Carphone Warehouse to rob you of the right to own the SIM FREE device that you have purchased them. EE are willing to unlock the device, but at a fee to me. I feel this fee should be paid by Carphone Warehouse. I am disgusted with them at their blatant disregard for consumer rights. When I questioned the sales clerk on the legality of doing this I was told that they do and so it is legal. If anyone is looking at purchasing from these thugs, I would say stay away!
