Now that Department Store, John Lewis have started selling the new iPhone 6S and 6S Plus, I'm sure many buyers will be tempted to purchase one of their Sim Free models from there with offers of 2 year guarantee and free Click & Collect. But if you think 'Sim Free' means Unlocked then you gonna get a nasty surprise when you try to switch the sim card to a different network! From the small print in the iPhone specs: "Please note: iPhone will lock itself to the network of the first SIM card that is used in the phone. Subsequently attempting to use it on any other network, for example by replacing the SIM card, may mean it becomes permanently unusable. SIM free iPhones can only be used with a UK-network SIM card, and will not accept foreign SIM cards." Yes, this is exactly the same situation as Sim Free iPhones purchased from Carphone Warehouse which has infuriated so many buyers who have tried (many unsuccessfully) to unlock their phones. The retailers argue that the term 'Sim Free' simply means that the phone is sold without a sim card. But since pre-Smart phone days, most people have associated the term with 'off contract', hence unlocked. So, why on earth are Apple advising/allowing these retailers to sell these iPhones as 'Sim Free' ( which are the same price as fully unlocked Sim Free handsets from Apple themselves) causing so much confusion and disappointment?
