Been looking at the radio specs on this ( compared to HTC One) and it seems the GSM/UTS and LTE bands/frequency are all the same except for one of the LTE. The 800Mhz uses band 20 while the HTC One uses band 18. The 1800Mhz and 2600Mhz match.
Would this preclude it from working on Sprint?

Please see this thread:
http://forum.xda-developers.com/ascend-p7/help/verions-p7-t2838058
It shows the different versions of the P7 for use in different countries.
I don't think it will work at all on Sprint, as Sprint is a CDMA network.
Also -- again -- My understanding -- is that the Chinese CDMA (TD-SCDMA) is an entirely and completely different thing (different frequencies, different protocols) than the US Sprint/Verizon CDMA. The P7-L00 would not have 4G at all (and spotty or no 3G) in the US.
For the P7-L10 ("International Version") it would work as follows:
It will work as a basic 2G phone on AT&T or T-Mobile in the US.
It should work on AT&T or T-Mobile 3G in some areas, but since it is only quad band - (No 850MHz band - Not penta band) it may not work in all areas.
4G LTE will not work on AT&T or T-Mobile, or on any provider I know of in the US.
AT&T uses Band 17(700Mhz), Band 5(850Mhz), Band 2(1900Mhz), Band 4(1700/2100Mhz)
T-Mobile uses (apparently) only Band 4(1700/2100Mhz)
The P7-L10 uses LTE: B1/B3/B7/B8/B20
No overlap means no 4G at all.
There is supposed to be a P7-L16 international version that may have different 3G/4G bands, but apparently it has not shipped yet, or at least I do not know where to buy one.
Note, however that it does have WiFi, so as long as you do not mind paying a premium for 4G LTE that will not work at all, you'll have plenty of data connectivity as long as you have WiFi available.
Hope that this helps. This is what I have found in my research, as I would really like to buy one of these phones, but as mentioned, I cannot see paying the price these phones sell for, and then have no 4G at all.
Those in the know, or who have one in the US, please comment/correct.

I'm considering whether to buy an T-Mobile version and unlock it or a "Officially Unlocked" version on HTC's official website. I have found two differences so far.
(1) The first is that T-Mobile version seems to support more 3G networks while Unlocked supports more 4G networks.
Here is something from HTC official website.
Unlocked version
HSPA/WCDMA: 850/1900/2100 MHz
4G LTE: 700/850/AWS/1900 MHz (US)
T-Mobile version
3G - UMTS/ HSPA: 850/ AWS/1900/2100 MHz with HSDPA up to 42 Mbps
4G - LTE: 700 MHz and AWS band
AT&T version
3G - UMTS/ HSPA: 850/1900/2100 MHz with HSDPA up to 21 Mbps
4G - LTE: 700 MHz and AWS band
So does it mean that both Unlocked and TM versions can completely support AT&T network, TM version can completely support TM network (of course), and Unlocked version partly supports TM network (no 3G AWS support). Am I right?
(2) The second is about S-OFF. Neither Revolutionary nor Moonshine mentions the Unlocked version, but they both support TM version.
PS: Can I use more frequency bands by flashing something into an S-OFF HTC One?
If you're going to use it on T-Mobile, why not just buy the T-Mobile version? The unlocked version doesn't have support for AWS bands.

I'm not quite sure which operator will I use.
if your in the USA the tmobile version will probably serve you the best since it can pick up pretty much every companies 3g and 4g signal without problems. tmobile or ATT.
there is currently no way to flash a radio to support other bands not sure if this is even possible currently

I am on a TMobile branded phone, which I unlocked to use with my AT&T account, on which I previously had an iPhone 4S. I've been having some issues getting on LTE so far. I did talk to AT&T several times to make sure that the One was provisioned on my account, and the account was changed to a "4G LTE" data account. I've driven all over the downtown Los Angeles area (downtown, Chinatown, Dodger Stadium, Commerce, and Hollywood) and have yet to see LTE when I'm on AT&T. I get it fine on Tmobile (I picked up a pre-paid Tmob SIM.) I've tried several different APNs (wap.cingular, phone, and pta (which doesn't even connect)). As of right now, I'm a bit stumped as to where the issue might be (it presents itself in Sense, Android Revolution, and Google Edition ROMs). I may just buy an HTC One from AT&T and will put my SIM card in it to see if I get LTE on there, and then return it.
My belief, and what just about everyone has said, is that the TMob phone should be able to get on AT&T's LTE. For whatever reason, and I can't quite lay blame anywhere yet (I'm new to Android, so it could very well be I'm not getting something), it's not working.
Hi everyone !
I came here because I'm about to buy an HTC One 801N Red (which I suppose is imported from the UK) but I'am unsure of its compatibility with Canadia carriers, in particular mine (Fido).
Fido's network uses 850/1900 Mhz for GSM, UMTS, HSPA & HSPA+ and 2100/2600 Mhz for LTE. The phone is advertised on Amazon as supporting 850/900/2100 Mhz for 2G & 3G HSDPA and 800/1800/2600 Mhz for 4G LTE.
Does supporting only one band for each service (850 for 2G/3G and 2600 for LTE) enough? Will it causes problem with using the data network?
Thank you!

So, from this post, I understand it seems to be compatible. My question was about how many bands it needs to support in order to work effectively. Is one band enough, or should it support both (850/1900) in order to work best?
Thank you anyway.
It depends on your carrier's network coverage. They may have predominantly 850mhz with 1900mhz towers in remote/legacy areas, or the other way around, or a mix.
So you could be buying a phone that works everywhere you go, or not at all.
I see that the Sony mobile US site has the z3c listed as coming soon. Is it best to just wait for that to come out or will the European version fully support all of the AT&T bands? I'd hate to import a phone and not get the best reception/internet.
I know it was suggested in another thread that it would work with AT&T but then there was some confusion in another thread about the phone possibly missing 1 or 2 bands. Any help from an expert would be greatly appreciated.

I know Sony's white papers have been wrong in the past (Z1 Compact with glass back, grrrr ) but the one for the Z3 Compact D5803 has 4G bands Bands 1, 2, 3, 4, 5, 7, 8, 13, 17, 20.
I've had a hunt around for AT&T's 4G bands but this seems a but trickier as it seems dependent on region, going by wikipedia it looks like the main bands are 2, 4 and 17 which are all supported by the European version per the above. It probably doesn't help that I'm not from the US and I don't have enough posts to add the URLs, sorry.
I feel like I remember reading back in the day that some companies used bands of the same frequency that weren't cross compatible. It's always made me nervous about buying non US phones. However my info could be wrong.
When I was in the states, I got a AT&T sim card. My phone definitely says that it has the lte bands. Still, it only displayed h+ while I was there. I did not bother to go back to the store and check because the speed was very good anyway. So maybe it's because the bands are different or it was working on 4g but just not displaying it, I don't know.

AT&T must provision your sim for LTE otherwise you'll only receive 3G even if the phone is capable of 4G. Usually they do this based on the IMEI of your device and if it's a non AT&T phone then it won't appear in their database as LTE capable. There are ways for them to manually configure the sim for LTE by contacting support.
The UK model D5803 definitely supports AT&Ts LTE on bands 2, 4, and 17.
Does AT&T have more bands than 2,4,17?
I found when googling AT&T LTE bands that they apparently have also started to use band 5 (850mhz) but that's still supported by the Z3 compact. This was both on AT&T's forums and howardforums but I'm not sure if AT&T need to do something else to enable LTE support on that particular device. I think my own network (3 UK) has to do this as it took a few months for my unlocked Moto X to pick up their 4G network.
From AT&T: https://www.att.com/shop/wireless/byop.html
Refer to the manufacturer's website to verify your unlocked device works with a SIM card on an AT&T GSM network frequency:
• 3G UMTS network 850/1900MHz bands
• 4G LTE network AWS / 700 / 850 / 1900MHz bands

AWS (1700/2100MHz) is band 4 (Blocks A, B, C, D, E)
700MHz is band 17 (blocks B, C)
850MHz is band 5
1900MHz is band 2
The overwhelming majority of AT&T LTE is on band 17. Bands 2 and 4 are used for additional capacity in some markets and/or some rural/smaller market coverage. I'm not sure they've rolled anything out on band 5 yet, but even so the Z3c has that covered.
OK,
thank you very much for the additional research. It seemed like that was the case but I don't trust my own opinion since I haven't done any real looking into this type of stuff in like 4 years.

To answer your original question, as far as we know there is no US model of the Z3c, only the EU D5803 and Asia D5833. If Sony sells it unlocked in the US it will probably be the D5803.
In preparation, hopefully I'll have it in a week.
Programming non-AT&T devices with the correct APN and MMS data settings
Subscribing since I'm very interested in this phone and my service provider is AT&T
Works great. I live in both NY and San Francisco, and I get LTE everywhere on AT&T.
I imported the D5803 (EU) model through Expansys.
Yes. Just make sure to get the d5803 model.
So after the denim update, AWS (aka 1700/2100 or LTE Band 4) support for the icon(929) became available, and because of this I purchased the Icon and I love it. However I live in Canada and have a month to month plan with Mobilicity. I guess I didn't do my research well enough (I'd like to think the internet was a bit misleading but....i guess its matter of perspective). Mobilicity solely rely on the AWS band frequency. They don't offer LTE but instead use HSPA . I knew that already but I figured that since AWS was supported I could receive HSPA signal over the 4G radio but nope I was wrong.
So I guess there are enough distinct differences between HSPA on AWS and LTE on AWS enough for them to be not cross compatible? Is this a hardware "issue" or a firmware/software one that I could do something about? Is it possible to enable 2G/3G/HSPA over the 4G radio? Or maybe I can get it to work by setting the APN correctly? I looked at some phones specs over on GSMArena which do offer HSPA + LTE support over AWS, I really want to say that it seems unlikely that 2 or more pieces of hardware are required to offer 2 services on what is essentially the same frequency.
Based on the specifications, it has GSM bands used by both, however SM-N920R4 is US Cellular CDMA...

Just from looking at the specs for this specific device it appears that it will work on all of T-Mobile's LTE bands but it is missing LTE band 17 support for AT&T. The 2G and 3G bands will work just fine as they match the specs for the N920T/N920A from both carriers. The only thing I am not certain of at this time is if you will have to have the device unlocked to be used with another carrier. Were you using this device on US Cellular or did you just pick this device up recently and want to use it with AT&T or TMO?
Ok thanks, the deal never went through
