I want to get the Iphone 6 but my carrier is MetroPcs. Can I buy the T-Mobile one and take it to MetroPcs?

Ask MetroPCS, or T-Mobile.

Some users have reported that if you buy the T-Mobile contract-free phone through the Apple store (NOT through T-Mobile), you can use it through other carriers.

Does MetroPCS allow you to bring your own device, rather than buying it through them?

If you buy an unlocked iPhone 6 (btw all verizon iPhone 6's are factory unlocked) you can bring your own phone and activate it by either buying a sim online and calling metropcs to get it activated or go into a store and they will charge $20-$30 for a SIM card and get you activated. I've had an iPhone 5s and 6 going on metropcs for a year. Since the iOS 8.1.3 update, if your in a bad service area and lose LTE you will have to reboot your phone to get your LTE back. iOS 8.1.2 had a toggle to turn LTE on and off but iOS 8.1.3 and up that option has been eliminated. Also, everytime I receive or make a phone call my phone drops to Edge or GRPS and I have to reboot my phone. It's a hassle and I don't recommend metropcs unless you're on a real tight budget. I have unlimited everything including LTE for $61 per month. Sometimes I use 200-300 gigs of data by using MyWi or Tetherme. There is no current jailbreak for the current iOS 8.3 firmware so my iPhone is no fun. I'd suggest getting a Galaxy S6 and bringing it in on the bring your own device plan!
