It's been figured out, I speculated it was possible, and it is!
Preamble
Hi everyone. As we know, the C6603 (all country versions) can be swapped with the radios from the ZL. This allows you to get LTE on Rogers and Fido in Canada, and I assume would work for other carriers as well in other parts of the world. (this is due either to unlocking frequencies, or unlocking channels on those frequencies.)
The radio HARDWARE is the same. *(?!? is it?) From what I understand the baseband chip in ALL the devices is a:
Qualcomm MDM9215M
which fully supports all the bands we can possibly use. Meaning, this device CAN use UMTS 4 1700/2100 for T-Mobile and Wind and Telus etc etc.
The secret is the amplifier chips. If the c6603 has the amplifier chips physically that the c6602 does we should be able to do the same trick that was done on the nexus 4. A modification of the build.prop may allow for AWS networks to work on our c6603. We can only hope. Partial support to at least use the AWS bands should be possible for the 6603. You would have to do the same thing that was done for the google nexus 4. Essentially,
#!/sbin/sh
echo "telephony.lteOnGsmDevice=1" >> /system/build.prop
echo "ro.telephony.default_network=9" >> /system/build.prop
echo "ro.ril.def.preferred.network=9" >> /system/build.prop
And then flash. Obviously requires a rom cook and root. If any intrepid developers wants to give this a shot, I suggest using the 6606 baseband, as it seems to be both a 6602 and 6603. The 6616 is essentially the same as the T-Mobile phone but with Canadian channels.
Why I care
When the Z first came out, I knew I needed to have it. By a terrific stroke of luck a local had bought an unlocked international Belgum phone off ebay and decided he wanted the S4 instead. He was selling it for hundreds below the MFG price on Kijiji. I immediately bought it. I love the phone, but I can only get 3g, as I am with Telus, and the phone "doesn't support" officially, AWS on Telus. Works with HSPA+ for whatever reason though, on non aws bands.
New knowledge not currently found on the forum
Bell uses AWS on HSPA+ as well as LTE. So does Telus, and Wind. (and Tmobile in the US)
Historically, only the C6602 has the frequencies needed for the other carriers. Bell, in Canada, recently released the C6616.
(LTE compatibility AWS, 700 MHz HSPA/UMTS compatibility 850/1900/1700/1900/2100 MHz GPRS/EDGE compatibility 850/900/1800/1900 MHz)
The question with no answer.
The question is: Can I apply the Baseband file from the Bell C6616 phone to get AWS 1700/2100 hspa/LTE on a C6603?
NEW!
Note: I'm not rooted, nor am I bootloader unlocked. Neat, eh?
Here's what basebands I've tried so far: (c6603 Generic BE, .67, 4.2.2)
c6506 US .434, c6506 US 0.423 - both work perfectly on 4.2.2, no issues. On Telus you can only see Telus, and AT&T, sometimes Rogers.
c6606 - Phone boots, unusable. Random reboots, locks up immeditely after swipe to unlock. Simply flashed baseband back to c6506. - This may be because I was using a 4.1.2 rom. I'm going to re-investigate.
c6616 - Phone boots, slightly usable. Random reboots, even in airplane mode. System.process freezes but eventually unlocks. If you screenlock, you need to reboot. Flashed it back to c6506 (probably due to 4.1.2 again)
ZL c6502 .434 global unbranded - Phone boots. RADIO SHOWS - (!!!) Phone completely usable. OMG I CAN SEE BELL 3g and ROGERS LTE (which is 2600mhz!). Something interesting is going on here, but it's not unlocking any additional bands in reality. The *#*#service#*#* menu shows the same frequencies available - but there's CERTAINLY some modification to the ranges in the bands. For those of you using .434 c6506, switch to c6502 global, you might get better speeds. Woot!
Z c6602 .67 Works. 2g, 3g bands including LTE (on 2600 only I'm sure) available but only on Rogers my home network, Telus, comes up as 3g H+. Cannot see Wind but that might be due to not having a wind Sim at the moment T-Mobile comes up as 2g only. I believe it uses umts 4 for 3g/4g. Essentially the same as c6506.
c6606 0.191 - phone slightly usable. Still has issues with random reboots. Won't go into info or network menu at all. This sounds like mismatched build.prop... this might be possible. Exciting.
MORE MAGIC FOUND. The info menu (*#*#4636#*#*) *#*#info#*#* allows you to swap country mode frequency ranges (including an UNKNOWN range on)!! This greatly impacts the available networks you see when you scan for networks in the phone. With USA selected I do NOT see T-Mobile, for example, when previous I did. Needs more playing.
Here's what I found out:

No worries, I really know what I'm doing here. I'm doing a baseband only flash.
Looking into flashtool, the recognition=C6602,C6603,C6606,C6616,L36h,yuga keys exist. Meaning, flashtool SHOULD see the c6616 in the list, but yes, it doesn't. (?!?!)
I recently grabbed C6506_10.3.1.A.2.67_Generic US, and it works flawlessly as thje previous c6506 basebands on 6603's did. On Fido, it'll give me LTE, obviously, but that's due to 2600 I'm sure. but only gives me 3g (hspa+) with Telus. (non aws).
According to the service menu, The phone only supports the following, even with the 6506 baseband flashed (screenshot is from my phone just now):

8 Up: 880 - 915 Down: 925 - 960
20 Up: 832 - 862 Down: 791 - 821
AND YET, the T-Mobile C6506 is supposed to support:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 900 / 1700 / 1900 / 2100
4G Network LTE 700 / 850 / 1700 / 1900 / 2100
Okay. So if that is the case... HOW IN THE HECK are some of you people getting LTE on Bell?
Bell's (and Rogers/Fido, Telus/Koodo) LTE network uses Band 4 Advanced Wireless Services (AWS 1700/2100 MHz: actually 1710–1755/2110–2155) in most coverage areas and Band 7 (2600 MHz) in a few areas.
Wind's and Telus's is 1700/2100 (AWS1) only. THE ONLY WAY I can see this working is because bell/rogers has UMTS 2600 in the GTA. HOWEVER: Why weren't we getting LTE (data only) in the first place on the 6603? It supported LTE 2600 from the start. It's a very good question, and one that could be because of the sub channel bands used for LTE on HSPA+. What's interesting, is that since this phone supports Band 3 and Band 1, you can SEE the LTE/HSPA+ AWS1 network, but it doesn't stay connected (Because you can't split negotiation bands... UNLESS, you could limit one antenna to one and one to the other (not sure it's possible)).
That's seems to be the ONLY reason it works on Bell/Rogers in some cases with the 6506 2600mhz baseband. You're not getting true AWS with that flash (which can be for hspa+ or LTE). Also, the c6616 appears to be a more complete radio that would literally work on every single network in Canada and the USA, being the "ultimate LTE" Xperia Z. The c6602 Internal Storefront phone is the closest original thing, to that I would imagine.
Oh, I forgot to mention, I did try the T-Mobile 6606 baseband on the phone. It causes a soft lock after booting sadly (which does get into the OS, but it locks up and goes black once it's there.), and you have to flash back to either 6506 radio or stock to get it to stay stable.
So no, I do not believe this phone can be "told" to use AWS, regardless of what baseband file you stick in it. Now I'm not so sure. The same thing that was done on the Nexus 4 should work here.

I'm not sure it will work at all, apologies if this has been explored. The phone only supports limited UMTS bands. In particular, it would need to say UMTS 4, 9 or 10 in that list, I think.

This is correct, sort-of. It turns out that the radio hardware chips themselves are actually the same, but the unit is missing the physical amplifiers for the frequencies you would unlock, making them impossible to use. It's the c6603 radio hardware that has euro LTE. However, the 6602 is supposed to support AWS in some fashions. If you flash the baseband from the bell Z, you may be able to use AWS 4, because it's not just the frequencies that you make available, it's the CHANNEL SET.
In summary a "baseband" is three things
1) radio driver
2) frequency range list
3) channel range list
In theory (logically), the baseband from the "unbranded sony store" phones of each hardware model variant should have all the carrier frequencies of the local area.
So, if you're from Germany, flashing a the Sony "carrier unbranded" baseband from the local model variant should allow you to be all all carriers in that region because it would be in Sony's best interest to sell an unlocked phone in that region in that way.
It gets dicey when you bring a phone from another country as I did, into a country that uses different radio frequencies and channels for the same wireless protocol types. It's complicated and has to do with the radio telecom standards differing in every country. True "World Phones" are really uncommon but we're getting more standardized every year.
I still own my Z but I also have a Z1. The Z1 is a LOT more compatible (every carrier in my area) because it's designed to work with local frequency sets. All I had to do on it was flash the Sony official firmware and baseband, and I could get LTE on every carrier.

Only way to find out is to flash the baseband and see what happens, if not you can always flash back to stock C6603 baseband.

Unless of course, someone can provide a baseband that "unlocks" UMTS 4, 9 or 10... And, that the radio is physically capable of doing it.

As i see from different firmwares, some overlay applications might deny to use some of capability of phone.
In over my firmware testing experience, some off firmwares prevent to use single 3g, and some of them prevent to use mixed network.
You must sure you have totally generic firmware. Try to delete all overlay apks, those might restrict you to configure network coverage.
PS:
I'am going to flash C6606 fw 10.3.1.E.0.191 to my 6603 afew later.

Hi Eryen, thanks for replying!
If you read through my post, I tried that and it did not work. Gets to the OS and locks up. However, we're just swapping signed basebands. We need to figure out which radio hardware they're using to see what it's capable of, and perhaps, we can start making custom unlocked drivers.

So I'm starting to think the 6603 could be hacked to get umts band 4 in the same exact way the nexus 4 was.
If I get more time I'll try this out - I would rather it be possible without root but meh.
To contribute.
I have C6602, flashed C6603 baseband, tried with 4G card in confirmed zone of 4G signal, only catching 3G.
Will try with C6502 baseband when I have again 4G card.

I'm not sure it will work at all, apologies if this has been explored. The phone only supports limited UMTS bands. In particular, it would need to say UMTS 4, 9 or 10 in that list, I think.

I'm deeply grateful with you and your work, i don't know if you are a developer or just a guy who got a Xperia Z and wants to enable some features that's been banned from sony and of course making us the job to reroute this, even harder than nexus 4 disabled LTE feature, i have just 1. question, i own a Xperia Z (C6602) i'm on existenz 6.6 ROM wich is based on official 4.3.
I have understood that XPERIA Z C6603 and C6602 version both bring along the exact same LTE chip BUT sony disabled this chip on C6602 version for an unkwon reason yet, i've read around so much about it, and i concluded, that the chip on C6602 was disabled by some modem modifications,
how can i enable LTE feature?
if i flash C605 modem will work and get LTE?
i am from colombia and my carrier is TIGO (german company) they uses AWS band 4 for LTE speeds
any help from you and yor knowledge, sorry if i bother you with this but i need to make clear this hole in my head once and for all dude
THANKS in advance

The C6602 does not have an LTE capable radio. I'm not sure where you heard that it does, but that information is incorrect. There is no way for you to use LTE on your device, no matter which baseband you may flash.

This is correct, sort-of. It turns out that the radio hardware chips themselves are actually the same, but the unit is missing the physical amplifiers for the frequencies you would unlock, making them impossible to use. It's the c6603 radio hardware that has euro LTE. However, the 6602 is supposed to support AWS in some fashions. If you flash the baseband from the bell Z, you may be able to use AWS 4, because it's not just the frequencies that you make available, it's the CHANNEL SET.
In summary a "baseband" is three things
1) radio driver
2) frequency range list
3) channel range list
In theory (logically), the baseband from the "unbranded sony store" phones of each hardware model variant should have all the carrier frequencies of the local area.
So, if you're from Germany, flashing a the Sony "carrier unbranded" baseband from the local model variant should allow you to be all all carriers in that region because it would be in Sony's best interest to sell an unlocked phone in that region in that way.
It gets dicey when you bring a phone from another country as I did, into a country that uses different radio frequencies and channels for the same wireless protocol types. It's complicated and has to do with the radio telecom standards differing in every country. True "World Phones" are really uncommon but we're getting more standardized every year.
I still own my Z but I also have a Z1. The Z1 is a LOT more compatible (every carrier in my area) because it's designed to work with local frequency sets. All I had to do on it was flash the Sony official firmware and baseband, and I could get LTE on every carrier.

Actually it's not exactly true. There is a custom kernel mode driver that locks this radio from using the other frequency bands. It may be possible to cook a custom driver that enables them, but the amplifiers might not be there, although I suspect they are just like the Nexus 4. The reason they are strongly disabled is because enabling them in a country that uses those channels and frequencies might break their local radio telecommunications laws and it would not allow them to sell the device in the country with the radio being "un neutered". That's one of the reasons why pushing these things through the FCC can take time.
So, am I correct or not? You said I was in post #17 and not in post #18!
If it's kernel related, then surely flashing a C6603 kernel would bypass it (which it doesn't)...? Correct me if I'm wrong, as I'm only an interested amateur.

Truth is we don't know for sure because nobody has done it, we're talking about writing a custom driver which is different.
Qualcomm MDM9215M
which fully supports all the bands we can possibly use. Meaning, this device CAN use UMTS 4 1700/2100 for T-Mobile and Wind and Telus etc etc.
The secret is the amplifier chips. If the c6603 has the amplifier chips physically that the c6602 does we should be able to do the same trick that was done on the nexus 4. A modification of the build.prop may allow for AWS networks to work on our c6603. We can only hope. Partial support to at least use the AWS bands should be possible for the 6603. You would have to do the same thing that was done for the google nexus 4. Essentially,
#!/sbin/sh
echo "telephony.lteOnGsmDevice=1" >> /system/build.prop
echo "ro.telephony.default_network=9" >> /system/build.prop
echo "ro.ril.def.preferred.network=9" >> /system/build.prop

Copied from phone arena, yet device page doesn't list the bands.
"The FCC filing is for a *Motorola device with the model number*XT1254, which matches the leaked DROID Turbo model number we've seen before. The odd thing is that the filing lists support for*LTE Bands 2, 4, 5, and 17, and GSM and WCDMA frequencies at 850MHz, 1700MHz, and 1900MHz. Those bands match up with AT&T and T-Mobile; but, the DROID Turbo would be a Verizon device"
My question is for my friend who uses cricket. Would the droid turbo work with cricket?

just wait, next week we will have full specs and we will know for sure.
There are two Droid Turbo listings that have gone through the FCC.
FCC ID: IHDT56PK1 is the Verizon Droid Turbo. It has support for:
GSM 850 / 900
WCDMA Band II / V
CDMA2000 BC0 / BC1
LTE Bands 2/4/7/13
This is pretty much a typical "global" Verizon phone. It does not support AT&T LTE bands but should work on their 3G network. Cricket uses the AT&T network. However there is that second Droid Turbo listing.
FCC ID: IHDT56PK2 is the other listing, it is stated as electrically identical to the Verizon Droid Turbo. It has support for:
GSM 850 / 1900
WCDMA Band II / IV / V
LTE Bands 2/4/5/7/17
This is more or less an AT&T version of the Droid Turbo. So this would be the phone you should be looking for when it eventually comes out.
Networks and Bands
CDMA/EVDO Rev A (850, 1900MHz)
LTE Cat 4 (bands 2, 3, 4, 7, 13)
Carrier Aggregation (B4+13)
GSM/GPRS/EDGE (850, 900, 1800, 1900MHz)
UMTS/HSPA+ (850, 900, 1900, 2100MHz

Probably not.
I put my ATT SIM card in, clicked on the "not a verizon sim card" pop up to make it go away.
Had a 3G icon but speeds are not bad, getting 6-7 Mbps / 2 Mbps (down/up) on ATT. Configured proper APN and it still did not matter.
Put the Verizon sim back and had LTE and noticed the APN I saved for ATT was gone and the Verizon one was back.
In any case, I don't plan to use this device on ATT but was curious if that (ATT) sim would work. Why? If it works (which it did, placed calls, and sent SMS), this means I should be able to travel overseas and use another SIM card. It was a question I could not get answered in the corporate VZW store. Now I know.
I'd suspect TMO LTE would not work. If you plan on using the device full time you probably won't have LTE speeds.

AFAIK, Turbo support band 2, 4 which is compatible with T-Mobile. (1700, 2100).
I don't see the supported band in 3G and GSM but 4G
Also, Motorola planned to launch an international version of Turbo so if you don't want to get from verizon, you can get this version.
Yeah I'd suspect it was using HSPA+ because I've never gotten speeds much above 1 or 2mbps down with 3G.
Either way, definitely not a deal breaker, anything is better than dreaded EDGE/1X LOL.

I bought this phone on a lark to see if it would work on T-Mo, and I CAN receive LTE. I validated download speeds above 12 MBPS. The coverage seems to be a bit spotty and I am not sure what band is being picked up. I am in Minneapolis.

Yes, just tried it and was able to surf while on a call.
Speed tests show about the same speeds as well, approx 6 down, 2 up.
However when on Verizon there is no data when on a call. They need to enable LTE for voice and data. I believe it's Advanced calling 1.0.
Interestingly enough I got a text yesterday afternoon on my other number that's on an iphone 6 that is now active.
Hopefully it won't be long.
EDIT: Even though the signal icon shows 3G when the ATT sim is there it may be getting LTE. My area doesn't get good signal, typ. -115dBM on LTE and -90 dBM for HSPA, etc. I'll have to try it in an area where LTE is stronger. In any case HSPA+ is pretty good, it surfs pretty fast.
Thanks guys

Hey guys,
Picked up the Turbo at a Buffalo best Buy and set it up today on Rogers/Fido. Couldn't seem to get an LTE signal even though the phone and network seem to be compatible on LTE band 4.
Anyways, for any of those wondering about this or considering doing the same thing and bringing a Turbo up north, after about an hour 4G LTE switched on by itself and I must say these speeds are incredible. 76MB Down and 17MB Up. My home cable speeds aren't that fast.
So basically, anyone reading this thread in Canada. Fear not and buy this beast of a phone.
P.S. (I used the "LTEMOBILE.APN" APN)

Telus sells the XT1097, your looking at the XT1095 out the US just don't pick the AT&T model as it has a locked boot loader that seems cant be unlocked at all..... The Telus model, supposed to have the quickest updates... well thats a lie.... there is no update as of today... and no indication of when either...
I was able to buy a XT1095. I still haven't received it but now all I can think about is "What if I need to use the warranty for some reason?". Did anyone in Canada have to go through that?

I asked a similar question (but for Telus) on howard forums. This is the response i received o0vL
"Moto X - Pure Edition (GSM Unlocked with T-Mo SIM - XT1095):
GSM/GPRS/EDGE (850, 900, 1800, 1900 MHz)
UMTS/HSPA+ (850, 900, 1700 (AWS), 1900, 2100 MHz)
4G LTE (2, 3, 4, 5, 7, 17)
Telus Moto X Specs
4G LTE: (Bands 2, 3, 4, 5, 7,17, 29)
4G (HSPA): 2100MHz (Band I) / 1900MHz (Band II) / 1700MHz (Band IV) / 850MHz (Band V) / 900MHz (Band VIII)
Seems like the Pure Edition is missing band 29, where its available on the Telus version. Not sure if it will affect the LTE connection"

On another thread on this site, someone mentioned that the hardware is the exact same on the canadian model as it is on the pure edition model, the only difference is the firmware. So it seems to me that a radio flash might be required in order to receive the proper bands. I'd love confirmation on this, as I plan on using motomaker in the US to build my phone.

You can't actually change the modem files, you must you the original meant for the phone. The XT1095 supports all of the 2G,3G and 4G bands that Rogers/Bell/Telus/Fido/Virgin/Koodo/Wind/Mobilicity use in Canada. You don't need to do anything but insert your nano sim and possibly program the APN to get network data.

thanks for the reply Steve, so the lack of band 29 shouldn't be an issue? LTE speeds should be achievable?
