Hi! I just received an iPhone 6 I purchased from amazon that is supposed to be unlocked. When turned on, it Shows me a selection of carriers only in the US to choose from. I want to be able to use other carriers internationally without any problem and not a US carrier. When I checked online for solutions, I was told to select Verizon that it would unlock the phone to be able to use other GSM networks but was not told if I could use it on other GSM networks round the world. My question is this, can I use this phone with other GSM carriers round the work like in Africa where I would be heading soon and would be there for a while? I want to be able to use this phone any where in the world. I also got a reply mail from the seller who contacted the manufacturer and got a response that the iPhone 6 was a loner phone and that Verizon should be selected so that at&t and the rest could be used. Does this mean other gsm round the world are also eligible ? Thank you for your time and response
