The new phone is unlocked. That’s how it comes from Apple when you walk into the Apple Store and pay for it. You are getting a locked phone because you are buying through AT&T.
I travel extensively and use local SIMs wherever I go. In the US my average usage is $30 a month. The current price for an iPhone 6 is $700 and up, depending on options. That’s why I wanted to know where you got a price that was so low.
Not according to Apple. Dinodino is talking through his hat I know what I'm talking about. . . having actually bought an iPhone 6 through an Apple Store with my girlfriend. Apple carried iPhones for every carrier. . . they were sold out of T-Mobile iPhone 6's at the Arden Fair Sacramento Apple Store by 3:30PM on Monday, all out of all carrier 16GB iPhone 6 except Sprint, of which they had a few in Silver and Space Gray, and completely sold out of all 6 Plusses. They were not selling ANY unlocked iPhone 6 at all, by company policy. Period.
You have no idea what you're talking about. The Apple store sells phones locked to the Big 4 carriers, in addition to unlocked phones.
