Since there are only four options on the apple online store(contract with at&t, sprint, verizon, and contract-free T mobile). I am not available to sign up a at&t contract, but I am a at&t customer. And I just joined my friend's family plan, the at&t employee told me that I cannot switch to a iphone6 contract in 6 month.

 

So can I just buy a contract-free T mobile iphone6 plus from apple online store and use at&t sim card? Will it be OK with the at&t service and the 4G internet service?

I'm not sure if the T-Mobile contract free iPhone is SIM unlocked, which is what you would need. Typically Apple starts selling SIM unlocked iPhones within a month or two after the initial release, so your best bet would be to wait until that happens and just buy a SIM unlocked one. You will then be able to use it on AT&T network. I would suggest you stop by an AT&T corporate store so that they can get everything set up right for you (some of the features, such as FaceTime and mobile hotspot require AT&T to add appropriate codes to your account).

You sure can! 

I generally stand in line on launch day since I had almost zero success for preorders to deliver launch day. Purchase the T-Mobile version of the iPhone for full price and it is factory unlocked for GSM carriers including AT&T. I am using the 6+ version of T-Mobile phone with AT&T.

The contract-free T-Mobile iPhone 6 purchased from Apple is unlocked and can be used on any LTE network.  There are reports that the same phone purchased from T-Mobile may not be unlocked.

its unlocked and the LTE works.  Actually the Tmobile version works on Verizon also.

If you have any questions about usage, you can double check your phone's IMEI on the Bring your own phone link on AT&T's website. You should be fine with the T-Mobile version provided it's unlocked (should be).
