Turbo on other US networks, (T-Mobile and AT&T) by gordonzhao 30th November 2015
Lots of people have been running the Droid Turbo on T-mobile and AT&T from the very beginning.
I know, because we kept answering the same questions over and over. Everyone would start a new thread just to ask if they could use the Droid Turbo on T-mobile or AT&T. But here's people from October 2014 using T-mobile...
OCTOBER 2014
I am using the turbo on T-mo
Hey,
I purchased the turbo and popped my t-mo sim in and set the APN for T-mo, and I am getting G, 3G and LTE. I dont seem to be getting HSPA. I get LTE most of the time and normal speeds, like 30MBps. I am really happy to have LTE. I am in minnespolis, so I am not sure which band is coming in...
NOVEMBER 2014
I just bought the phone today and swapped in my Tmobile Nano Sim. Its working perfectly with full LTE in Chicago. I had to add the Apn settings under mobike network to get it to work. Whenever I reboot the phone a notification reminds me that i'm not using a verizon sim. Its easily dismissed. I cant be happier, this is the "Nexus" I wanted all along.
(Just like me, he was aghast at the size of the Moto Nexus 6, coming after the 2013 5" LG Nexus 5. For the next Nexus phone in 2014 everyone wanted slightly larger, like 5.2", 5.3" at most, and 1440p for the gen6 Nexus but not 6 inches! So, this 5.2" 1440p AMOLED Moto Quark was the "Nexus 6" we wanted. Had almost all the same specs, and even a bigger battery than the Moto Nexus 6 but in a reasonable size.)
No activation at Verizon. Just pop in your sim and configure the APN correctly to use tmobile, and you're off and running
Tons more.
Those users get LTE bands 2, 4 plus HSPA. They'll get T-mobile and AT&T LTE bands, just not all the LTE bands.
FCC ID IHDT56PK1
- Droid Turbo XT1254 (and XT1250) has LTE bands 2, 3, 4, 7, 13
- AT&T has LTE bands 2, 4, 5, 17. (Very little LTE band 5 locations and even then rarely only LTE band 5, so LTE band 5 is not extremely important but I wanted it since I use AT&T.)
- T-mobile (USA) has LTE bands 2, 4, 12.
Two years ago, LTE band 12 for T-mobile was not that important but now it is.
Here's a YouTube video from November 2014 (soon after the phone was released):

However, in that article above, he's wrong that the Droid Turbo was exclusive to Verizon. The name "Droid" is exclusive to Verizon but
the exact same device, with exact same FCC ID and bands was sold by regional U.S. LTE/CDMA carriers under the XT1250 Moto Maxx name. The "Turbo" name was also attached to another Quark, the Moto Turbo XT1225 in India.
NOTHING about the Droid Turbo was "exclusive" to Verizon, except the locked-down bootloader. 
But Verizon's PR department did a magnificent job convincing the world otherwise!

I *think* they can legally do that because it's a prepaid device. I believe that FCC stipulation only applies to non prepaid devices. But I'm not entirely sure. But I do know the Droid Turbo is usable on other carriers without any issue.
Right. I can show a few dozen posts from T-mobile and AT&T users dating back to October 2014. The only issue is people wish the Droid Turbo XT1254 had more LTE bands for AT&T (LTE band 17 and even LTE band 5) and T-mobile (LTE band 12), which is why I bought the "international" version -- the Moto XT1225 -- which had all the AT&T LTE bands.
Even then Motorola wouldn't initially
officially admit the XT1225 had LTE band 5, even though the FCC found it.

Later, when the XT1225 was released in India (same FCC number, therefor the same bands) they admitted LTE band 5 and another HSPA band used by T-mobile (HSPA band IV). Of course by then, users in Canada had confirmed those were already there and I had found them using Qualcomm modem testing software QPST, etc. So, Motorola was only admitting what we already knew -- finally.
The XT1225 and XT1254/XT1250 all share LTE bands 2, 3, 4, 7.
The XT1225 additionally has LTE band 5 and 17 (more bands used by AT&T).

Too bad the only way to use my prepaid Verizon Moto E LTE with my postpaid SIM is to pay Verizon a bs first month payment. Killed my account for a day before when I tried it.
Here's their policy, a part of which I quoted on the previous page.
http://www.verizon.com/about/consumer-safety/device-unlocking-policy
Postpay they do not touch:
We do not lock our 4G LTE devices, and no code is needed to program them for use with another carrier.
Droid Turbo was postpay.
But if curious, for
prepay:
We do not lock our 4G devices, other than our 4G Phone-in-the-Box Prepaid phones. In order to partially offset the subsidy we provide to make our 4G Phone-in-the-Box Prepaid phones more affordable to service customers, our 4G Phone-in-a-Box phones may only be used with Verizon Prepaid service for 1 year from original activation date or until payments in the amount specified on the back of the Phone-in-a-Box package are added to the Prepaid account.
Once either of these criteria is satisfied, you can contact us at *611 from your Verizon Wireless Prepaid phone, or (888) 294-6804, and we will provide you with programming instructions so you can unlock your phone. If the user guide for your phone does not provide instructions to access the programming menu, we can help you with that as well.
