Can you put an AT&T SIM card in a T-Mobile iPhone 6 Plus?

Can the T-Mobile iPhone 6 work with any carrier? IIm currently with AT&T and IIm looking to buy a T-Mobile iPhone. Will everything (like LTE) work flawlessly?

You probably won't get LTE use in most areas, but you should be able to get 4G and possibly LTE in some areas, depending on where you live. At the very least you will definitely get reception for calls and text messages. Calling T-Mobile and AT&T is the fastest way to find out. Ask T-Mobile which bands the iPhone 6+ supports and ask AT&T which bands they use for LTE. If these numbers overlap, it should work.

You're planning to use the T-Mobile iPhone 6+ on AT&T, right? It'll work flawlessly fine even the 4G LTE although you'll have to set up the APN for AT&T. T-Mobile iPhone 6+ will be contract-free and it's unlocked too, just put your SIM in the phone and activate, update the firmware too. That's all. You can also buy Verizon iPhone 6+ which are unlocked too. If you need unlocked iPhone 6+ at reasonable price cheaper than retail, mail me for more info.

  • Can you put a T-Mobile SIM card into an iPhone 5? So i have a really crappy flip phone and i really want an iPhone, I'm currently saving up for one.

My brother recently gave me his iPhone 4s since he got the new iPhone 5, so I can't make calls, or text, or get on the internet (unless I have Wi-Fi). I found my way into the sim card slot for the iPhone, but my MyTouch 4G sim card is too big.Me and my Mom are going to go the T-Mobile store to get a micro sim card so I can transfer my data onto it, so I can put it in the iPhone. Will it work?
