I just know some basic info about the B12: it covers the 700 MHz spectrum, where T-Mo guarantees coverage in especially rural areas. that lower frequency has a longer range and is supposed to penetrate walls better, but doesn't hold as much traffic as higher frequencies (shorter range but ideal for metropolitan areas).So the T-Mobile version supports band 12, and the AT&T version has band 30.
Can someone explain what the differences and benefits of these bands are?
The sim free unlocked version is now available for purchase on US Apple Store online. Can someone confirm which model this is.? Some are saying 1633/1634 and others 1688/1687. I purchased a 6s plus but nowhere does is say the model number only says 6s plus rose gold 128gb free.

The SIM-free iPhone 6s model is A1633 and the SIM-free iPhone 6s Plus model is A1634.
The question is then, what the difference is between the AT&T model and the SIM-free; My guess would be that the AT&T model comes with an AT&T sim included, while the SIM-free does not. I have no evidence to think there would be any other difference. However it begs to reason why one could not reserve an AT&T phone, purchase full price, pull out the sim, and from that point have it be exactly the same as SIM-free. It seems they should be able to combine AT&T/SIM-free into a single inventory item, but I am guessing for business or inventory organizational reasons, they are separated
also, the SIM free model would be whitelisted in Sprint and Verizon systems, whereas the AT&T version would not be. Not that Apple couldn't get it added to the carriers whitelist if you were to purchase one and need it activated on one of those carriers, but it wouldn't come that way automatically.
It should be noted, that although the AT&T model and the SIM-free model are both 1633/34, Apple is evidently using an internal identifier to separate the two types in their system. From Apple's iPhone reservation system:
![]()
![]()
We can see though they are both A1633, they are clearly different stock in their inventory. The question is then, what the difference is between the AT&T model and the SIM-free; My guess would be that the AT&T model comes with an AT&T sim included, while the SIM-free does not.
EDIT: The SIM-free model will also have the difference of already being whitelisted in other carriers' systems. Thanks solodogg!
On a side note, all SIM-free iPhone 6s 128GB models are out of stock in Texas as of Oct 9, 9:30am.

^Another small difference: The sim-free has the sim tray removal tool, while the carrier iPhones don't have it. Not a big deal for sure, but using the tool is better than using a paperclip. Sometimes the paperclip is too big or if the paperclip is too small you don't get enough leverage to pop the tray.
so, the SIM-free model would work with Sprint Spark as well as a Sprint model would?
I didn't realise they would have the SIM-free version that soon.
Even an AT&T, Verizon, or T-mobile phone should work with spark if you can get them to whitelist the device. Sprint's website says you can bring an iPhone 6s from another carrier, but it's apparently easier said than doneso, the SIM-free model would work with Sprint Spark as well as a Sprint model would?

I figured the T-Mo and VZW versions would since they're the same models as the Sprint. I just thought the ATT (and now SIM-free) version/s would be missing a band or so on the CDMA LTE side.Even an AT&T, Verizon, or T-mobile phone should work with spark if you can get them to whitelist the device.

No such thing as CDMA LTE. LTE is LTE. The AT&T model has all the same bands as the Sprint model, plus band 30.I figured the T-Mo and VZW versions would since they're the same models as the Sprint.

I was just on the phone with them on Monday, and they were telling me it wouldn't be available for a while. I guess it doesn't matter now that I already went through the pains of having mine unlocked.I know. I think it's usually January at least for iPhone 6
well, I meant with the LTE Bands that the CDMA carriers are using.No such thing as CDMA LTE. LTE is LTE. The AT&T model has all the same bands as the Sprint model, plus band 30.
And the bands are the same with the exception of band 30well, I meant with the LTE Bands that the CDMA carriers are using.
Good question. I would think so, but I guess not since Apple bothered making the different versionsWouldn't it be more cost effective to just make the one with band 30 for everyone?
Definitely easier said than done. Sprint wouldn't give my mom an iPhone 6S SIM (she had a Sprint iPhone 5 with an incompatible SIM) for a "T-Mobile" iPhone 6S. My parents decided to port over to Verizon and got the same runaround. Fortunately the Apple Store had the Verizon model in stock and they just exchanged it. If they had the SIM-Free model 2 weeks ago this wouldn't have been an issue.Even an AT&T, Verizon, or T-mobile phone should work with spark if you can get them to whitelist the device.
