Actually marry, Verizon will still work as they support voice calling on the
LTE channel so no CDMA required for the voice fall back. Sprint though is a
whole different can of very rotten worms.
The only time you’ll have problems with Verizon is if you head out to the back
woods and are in a 1x area only but las I knew these were very few and far
between and becoming fewer and farther in between every day. You can’t say
that about Sprint. Sprint has whole sections of the country they don’t cover
with LTE like huge chunks of New York for example or Boston, the West coast.;)
You get the picture or lack of picture / coverage map as it were.

That is the difference. Maybe no big deal to most people. But if you thought
you were going to get one from T-Mobile and then pay it off and then move to
some other network like Sprint or Verizon, not so fast. The modem and your
phone won't go there.

They locked the phone to sprint and you were not getting it unlocked to work on
VZ. VZ was the only carrier to make their phones world compliant. I had a
friend who tried and got this to work. Their phones were true world phones.
By the way VZ and sprint are both in the CDMA spectrum. So, yeah for me this
is not big shock. I kind of had the feeling this would happen since about 2012
or so.

If you read the article, you will know that it has not always been this way.
The 6S and the 6S plus, no matter which carrier you purchase them from, would
work on CDMA or GSM. Since most of the rest of the world is on GSM, it may not
be a big deal. But if you buy one of the T-Mobile or AT&T phones and, a year
from now, you decide you would like to move to Verizon, you will be out of
luck. That is not true if you have a 6S or 6S plus.

iPhone 7 Models From AT&T and T-Mobile Do Not Support CDMA Networks
MacRumors: Mac News and Rumors / Joe Rossignol
Choosing which iPhone model to purchase this year should be more carefully
considered, as both AT&T and T-Mobile models of the iPhone
7<http://www.macrumors.com/roundup/iphone-7/> and iPhone 7 Plus do not support
CDMA networks such as Verizon and Sprint in the United States. Apple confirmed
the matter in fine print in the iPhone 7 tech
specs<http://www.apple.com/iphone-7/specs/> and on its
LTE<http://www.apple.com/iphone/LTE/> page.
[iphone-7-carriers]
A customer that purchases an iPhone 7 from Apple's website and selects AT&T as
their carrier, for example, would be unable to later use the smartphone on
Verizon, Sprint, or any other CDMA network, even if the device is unlocked. By
comparison, all iPhone 6s<http://www.macrumors.com/roundup/iphone-6s/> and
iPhone 6s Plus models worked on both GSM and CDMA networks.
A customer that purchases an iPhone 7 from Apple's website and selects Verizon
as their carrier, on the other hand, would also be able to use the smartphone
on AT&T, T-Mobile, Sprint, or any other GSM or CDMA network.
It was previously reported that Apple would switch to Intel
modems<http://www.macrumors.com/2015/10/16/intel-lte-modem-chip-iphone-7/> for
select iPhone 7 and iPhone 7 Plus models, including AT&T
models<http://www.macrumors.com/2016/06/10/intel-qualcomm-modem-split-iphone-7/>,
and Intel modems do not support the CDMA standard in the United States. That
is likely the reason why AT&T and T-Mobile models are limited to GSM networks.
[iphone-7-wireless]
Only Verizon and Sprint models support both GSM and CDMA networks
The same report said Qualcomm would supply modems for the remaining iPhone 7
and iPhone 7 Plus units, including Verizon and Chinese
models<http://www.macrumors.com/2016/06/10/intel-qualcomm-modem-split-iphone-7/>,
and this appears to be the case. Qualcomm modems support both the GSM and CDMA
standard, which explains why the iPhone 7 from Verizon and Sprint will work on
all carriers.
Qualcomm, which holds patents for WCDMA and CDMA2000 standards, is the main
CDMA modem supplier in the United States. The company developed the first
CDMA-based cellular base station in 1990, and since then it has licensed its
technology to companies like Apple in return for royalty payments.
Until this year, Qualcomm was Apple's exclusive supplier of modems for LTE and
Wi-Fi connectivity, which explains why the iPhone 6s and previous generations
supported both GSM and CDMA networks regardless of carrier. But with Intel
entering the mix, choosing which iPhone to purchase is now more meaningful.
[iphone-6s-wireless]
All iPhone 6s and iPhone 6s Plus models supported both GSM and CDMA networks
The lack of CDMA support in iPhones with Intel modems may be short lived,
fortunately, as Intel acquired CDMA
assets<http://www.fiercewireless.com/wireless/intel-continues-to-pare-mobile-losses-buys-cdma-modem-assets-from-via-telecom>
from VIA Telecom in 2015. It is believed that this acquisition could pave the
way for Intel to release its first LTE modem with both GSM and CDMA support as
early as 2017 or 2018.
Ultimately, the most obvious choice should be to purchase a Verizon or Sprint
model, even if you are an AT&T or T-Mobile customer, especially when
considering resale value. However, some customers may have difficulty
purchasing from another carrier, depending on their current status with their
existing carrier.
Apple should also release an unlocked SIM-free model in the U.S., likely based
on the Verizon/Sprint model, in a few weeks based on past launches.
