Will an AT&T iPhone 6 that has been unlocked work on Verizon? When I say work, I mean will it work just as well as a Verizon iPhone 6 including LTE, etc... Is it the same exact phone?

nope, no CDMA on the att.

vice versa would work though...
Also Verizon will not allow you to get a contract/use any phone on their network that is not a Verizon phone. I.e. buy att, can't use on Verizon (cdma aside)
Not true. An AT&T iPhone 6 will work on Verizon as long as the phone is unlocked. In the past, unlocked AT&T and T-Mobile iPhones would not work on Verizon. This is not the case with the iPhone 6/6+.

No

No it will not work. The confusing part of this question is that gsm phones used to not work on cdma networks for technical reasons. But modern phones and especially the 6 have tons of covered bands. So there are only a few differences in band coverage between the two iPhones that are offered. And both iPhones cover all the LTE bands you could hope for.

But the problem is a Verizon policy. Verizon only allows devices that were sold as verizon phones to connect to their network. They check the device number against their list of approved phones. It is not a technical issue. But you are out of luck.

Yep. Here's another thread:

Still better to buy the Verizon version, though, given Verizon will only activate whitelisted devices.
Verizon's phones are unlocked out of the box, because of an agreement with the FCC when VZW bought the spectrum from the government for LTE. ATT made no such agreement so while a VZW iPhone will work on any network, you need to unlock ATT's iPhone to work on another network.

I believe the chipsets are the same internally at this point so it doesn't really matter that VZW is CDMA and ATT is GSM, the iPhone is using a global chipset capable of using both networks.

Because for the first time, it seems CDMA radio is enabled on GSM iPhones. My AT&T iPhone is locked but it reports an MEID in Settings > General > About. It seems there's no technical difference now betweem GSM and Verizon iPhones (much like the iPad Air and rMini) so at this point in time, it's just Verizon's whitelist policy preventing users from activating their non-Verizon iPhone 6 and 6 Plus on Verizon's network.

I really hope the FCC questions Verizon for this. Part of their 700MHz spectrum license agreement is not preventing compatible devices from using their network. While Verizon is technically not blocking compatible devices from accessing their network, their policy to only activate whitelisted devices is against the spirit of the agreement.

I think it might be a work in progress? Because my AT&T iPhone does appear in the whitelist. It was a genius bar replacement though, so maybe Verizon just added all the genius bar phones to the whitelist (since Apple doesn't differentiate between T-mobile, AT&T, and Verizon for those anymore)

Hmm, probably because it was a genius bar replacement. Mine is an original AT&T pre-order from Apple and Verizon's online activation doesn't recognize it as a valid IMEI/MEID.

Yeah, that's possible. I wish I checked before I actually unlocked my phone; I'm not sure if that has something to do with it.

This.

But I'm curious is Verizon's policy might relax now. Especially now that all of the companies are pushing people away from 2-year commitment contracts w/subsidized phones and into no-commitment contracts with non-subsidized phones. Verizon has nothing to gain here and plenty to lose by not allowing someone to bring their old AT&T iPhone with them and activate it on Verizon.

Eureka!!!Was going to restore,but thought I would try again with the Verizon sim when lo & behold its working,everything(lte,cdma,voice,messages)fast download & upload speeds.Friend has tmobile so I popped in his sim its working also.So it seems an unlocked AT&T 6 or a 6+ will work on all carriers except for Sprint.

Thanks again!!

Maybe. But I was in Verizon store three weeks ago with my at&t phone 5 and asked to have it switched over to Verizon and keep my number. The clerk said no and that it had to be a Verizon phone. I was consolidating accounts since my blackberry was already on Verizon as was my tablets.

But I didn't do what poster did about just putting an activated Verizon SIM card in there and use it.

Older iPhone models will not work. Only unlocked iPhone 6 and 6+.

i havnet tried running my iPhone 6 full time on version so i don't know if they will call me on it

as long as you activate a verizon phone and then remove the sim card and put it in the iPhone 6, it will work perfectly fine

if you call them up or use the website to transfer or activate service to your t-mobile iPhone 6 it will not work.

if you find some way of activating that sim in another device and pop in, it magically works, once that sim is activated, they don't seem to care what your meid is

it is the sim card that authorizes you to the verizon network. it is not the CDMA radio. the only seem to care about MEID #s is when you activate service or are activating a legacy 3G cdma device
