    Ok, so I ordered my OnePlus 3T from OnePlus yesterday, I believe it's sold unlocked, but when it comes in, do I have to go to my carrier AT&T, for activation and possibly a new SIM? Or could I just put the nano-SIM that I have been using for 2 years now from my HTC One M8 into my OnePlus 3T? Will I get service no problem?

    Yeah you just put in your old sim and all should work automatically, if not then you can manually input ATT's APN settings. More than likely it'll work automatically. No need to get a new sim.

    Ok, I'll see, but you think there would be an issue with frequency bands, connectivity,etc..

    No as long as you got the right device for your region... I'm assuming you're in US (ATT) so as long as you have the North America device you're golden.

    The OnePlus 3/3T should work on AT&T. Like others had said, as long as you bought the correct version of the OnePlus 3/3T for your region.

    When I first got my OnePlus 3 back in July I had to make a few phone calls to the AT&T customer service to get LTE coverage. Maybe you will get LTE coverage right away thanks to all the others like me who called and had the OnePlus phones listed is LTE capable phones.

    I am in the south eastern USA. I have better LTE and LTE+ coverage on AT&T than I get on T-Mobile.

    I heard that the Nougat update fixed the AT&T service to have and show LTE. BTW, are you on Nougat? Is it faster or slower in terms of performance?

    I was only on MM for a day or so and only had 4G+. Once I did the Nougat update, it now shows LTE and LTE+ up there. Not sure of the differences, but I'd rather have LTE up there.

    I'm also on At&t and just swapped the nano SIM right over. Zero problems.

    To my understanding, 4G+ is superior to straight LTE. 4G+ indicates carrier aggregration... also known as LTE-A. So I wouldn't worry about seeing 4G+ at all.

    Not sure about LTE+... maybe that's LTE-A? = 4G+?

    You'll be fine as long as you got the US version. I am on at&t, originally had my Nexus 6p on there. When my 3t came last month I just popped in my sim card and everything has worked perfectly no hassle.

    It will get edge only out of the box. i have heard you could enable other bands to get it to work wit their other data bands.

    When I got the phone last Friday night I just ran the updates VIA WiFi and stuck 4.0 on and then stuck in my sim card and everything worked with no issues. LTE and so on.

    I discovered that LTE and 4G are the same thing in the USA. 4g+ and LTE+ are carrier integration of two LTE channels to increase speed...

    Oh I'm sorry I do not! But I can see where you would have thought that. I was just saying some folks on XDA I believe had have some success with Verizon. I have att and I have had no issues with APN settings. I know many have reported some LTE issues with att.
