I was under the impression that LTE would not be supported until Tango or Apollo, but the AT&T Titan II and Lumia 900 will have LTE while running Mango.
Is it something special about AT&T's LTE network that allows this? Or did Mango always support LTE?
If Mango supports LTE, how far off does an LTE WP7.5 device for Verizon seem? (Verizon said that the reason they don't support WP7 is due to lack of 4G LTE)
I'm not sure if 7720 supported LTE, but I think one of the newer releases does.
Mind you, LTE or not, AT&T uses GSM and Verizon uses CDMA, and it may just be that, while both are supported independently, the combination of CDMA with LTE is not yet tested. After all, most of the world uses GSM; CDMA wasn't supported at all until 7389 (NoDo).

Does it matter whether the phone uses GSM or CDMA for 2G/3G? LTE is a GSM technology (hence the LTE SIM cards on 4G Verizon phones), so I figured it'd be all the same to the phone.
I'd guess it's the combination of the technologies, since the phones aren't pure LTE. Being able to fall back from LTE to 3G CDMA, or being able to do data on LTE while taking a call on CDMA (something pure CDMA phones can't do at all), probably requires a bunch of extra work and testing.
It's also worth noting that Verizon may just be misleading people. They've shown no particular interest in the Windows Phone brand at all, right from the beginning. Between "Droid"-branded Android devices and iPhones, they don't seen too interested in other platforms.
I want to say yes it does because T-Mobile has 4G Windows phones at their stores.
T-Mobile isn't using LTE yet, though. Their "4G" is really more a "3.5G" technology - it's a faster variant of their 3G, not a completely new tech. It let them bring it to market early and deploy it widely, and it *is* pretty fast, but it's not LTE.

I stand corrected.
Mmkay. So my understanding is that Mango supports LTE on a GSM network (AT&T) as of now, but not LTE mixed with CDMA (Verizon)?

I guess I have to say on Verizon's defence, They only had a choice of 2 devices, because of their CDMA network. It's Microsoft that limited the options for Sprint and Verizon.
Yes, I do also believe that Verizon has Android and the iPhoney so far up their ass they don't see anything else...BUT, they have released in a Press statement that they would be interested in WP7 if it had LTE options available. Maybe the Lumina 900 would come to verizon...
Maybe we will, maybe we wont...
Waaaait... *Microsoft* limited the devices available to Sprint and Verizon?!? Not Sprint and Verizon themselves, who chose to use a technology almost nobody else in the world uses. Not the OEMs, who didn't build more CDMA-based WP7 devices. No, it was Microsoft, who will license WP7 to anybody who wants it and who have both a CDMA and a GSM version, who are to blame here? I'm confused.
The OEMs are the ones who decide what devices to manufacture. Of course, they do that based on having customers. If Sprint and/or Verizon were to ask for more WP7 devices, you can be sure HTC, LG, Samsung, Nokia, and maybe even Dell, Asus, or Sony Ericson would be willing to provide (Motorola seems to have no interest). Heck, Toshiba/Fujitsu *has* a CDMA/GSM hybrid phone running Mango - it was the first gen2 phone ever released! I'm actually surprised Sprint *hasn't* started importing it; the IS12T is a nice piece of hardware, and would complement the Arrive well.

It's not Sprint and Verizon's fault for choosing CDMA over GSM. They made the decision years ago, before smartphones even existed.
CDMA is actually the smart choice for a big country like the US. Each CDMA radio tower has a larger cover radius than GSM radio towers. Not only that, the call quality is usually better.
And China predominantly uses CDMA. As time passes, CDMA will become more prevalent.
That said, it's not Microsoft's fault, either. The reason there aren't many CDMA WP7 devices is due to OEMs not making many of them.

Keep in mind, the world is about 90-95% GSM. Microsoft decided to support the world wide standard before they went to CDMA on release(it was publicly stated by Microsoft). So, yes, it is sort of Microsoft's fault why there is only 2 US CDMA models.
OEMs knew this too. Make phones for 90-95% of the world or promote your efforts to a smaller market. It makes total business sense why it was done this way. Windows Phone 7 Didn't even support CDMA till NoDO months later after release.
China's CDMA is not the same as the US CDMA, its almost totaly different, WCDMA, they dont work together, so it's a different chipsets needed.
WIth that being said, Verizon or Sprint could of dumpped money at the project to get more WP7 devices but, with the problems with WM, they held back a little.
So, it's Microsoft and the carriers fault for the lack of CDMA phones. LTE is another thing totaly. We should hear about LTE WP7 phones at WMC coming up very soon.
A release for LTE based CDMA phones is another story....

OK, this is something I will address. There are three large mobile operators in China: China Mobile, China Unicom, and China Telecom.
China Mobile uses GSM/EDGE for 2G and TD-SCDMA for 3G.
China Unicom uses GSM/EDGE for 2G and UMTS for 3G
China Telecon uses CDMA2000 for 2G and EVDO for 3G.
What the local Chinese refer to as "CDMA" is actually W-CDMA which is a UMTS technology.

Whether or not Verizon choose to carry LTE Windows Phone is a political issue, not a technical one. Windows Phone does support both LTE and CDMA2000/EVDO.

I know this is an odd request, but is there anyway to use the internet while talking on the phone. Normally I wouldn't care but I'm tired of the iPhone goons hassling me about it since those new commercials.
If not would there be a way if I unlocked my phone for GSM so I could talk on one frequency and surf on another?
Please direct me to a link if this has already been answered, I searched and didn't find anything.
Whoo boy, the old GSM vs. CDMA debate. No to your first question; it's a technology limitation of CDMA, which is why AT&T loves flaunting that fact. GSM also has the leg up in the number of simultaneous connections for conference calling. If you're looking for ammunition, CDMA generally enjoys better penetration of structures, and I know that I have found my service on Sprint to be stronger and much more reliable than my old plan with AT&T. Some people would even say that CDMA offers better call quality than GSM, but that's a huge debate with opinions on both sides. Also, GSM's encryption method was cracked recently, making calls potentially more vulnerable to eavesdropping. Finally, even when I had my old Tilt on AT&T I don't think I did too much surfing while talking on the phone; I really don't think it's as amazing a feature as they make it out to be.
For your second question, the CDMA Worldphone edition Touch Pro 2 used by Verizon and Sprint does have a GSM radio, but the question has been asked before if both networks can be used simultaneously and I believe the answer is always no. Anyone else feel free to correct me if I'm wrong.
last I checked in order to use cdma/gsm phone networks at the same time can't you just pop in a sim card!!!!!

one word IMPOSSIBLE!!!!!!!!!! GSM and CDMA are hardware radios an unlock is IMPOSSIBLE unless the phone is a world phone with both CDMA and GSM but your phone doesn't qualify so try getting a GSM/CDMA hybrid and then come back to me. However verizon will upgrade to LTE which is GSM based!!!!!!!! watch em LTE will allow voice and data at the same time. When LTE upgrade is complete say goodbye and good riddance to CDMA it will be shut down soon!!!!!

qjsmartphone - I thought that the TP2 was a world phone and thus held both antennas for cdma and gsm?
trogdor1138 -thanks for the input.
now I'm with sprint, and they offer 4G. This may be an ignorant comment, but can't a world phone with both antenna's say call on cdma and use the 4G provided by sprint? Or am I missing something?

I'm not sure what you are talking about, but CDMA variant of Touch Pro 2 does have both GSM and CDMA hardware in them.
Also, LTE and WiMAX is a two new 4G technologies that will eventually replace 3G data.
LTE is not based on GSM, they are two different communication technologies.
Back to OP's question, if you are using CDMA branded TP2 you cannot surf and talk at a same time. It is limitation on CDMA technology.
4G and 3G is not compatible, is your grandparent's old 2G phone do 3G? no.
How about your 3G phone accesing 2G? yes. Usually when newer technology is being deployed, they make sure that it is backward compatible, so that they can lower battery consumption and remain accessible to area where new technology is not yet available.
Just be near wifi and then show them you can surf while talking.

Wait... HardSPL fixes that, doesn't it?... Oh well, I think I should stop stalking the CDMA forums when I have almost no idea on anything CDMA-related!
But, I'm still in favor of the WiFi suggestion!
mac people live in their own little world. don't let them bother you. sure, they can talk and surf the web at the same time...if they have 3g coverage. but there are areas where they have no coverage at all let alone 3g. then they can use the 'paper weight mode'. i also love how they tout their app store meanwhile we've had multiple wm app stores for years already. also i get to choose what apps i want to use without htc or sprint telling me what i'm allowed to.

I called up VZW and told them I was going to Europe and wanted to use prepaid SIM cards instead of paying Big Red the $$. They gave me the SIM unlock code and now I can use T-Mo or AT&T SIM cards with no problem. Only downside is that their GSM frequencies are slightly off from the rest of the world so no high-speed data when using VZW on GSM carrier in the states...

The Verizon TP2 has a simple SIM lock on it which is similar to standard GSM SIM locks. Remove the SIM lock and you can use any SIM card with a compatible network, including US networks.
The Sprint TP2 doesn't have a standard SIM lock, but instead has the US frequency bands disabled. Hence the need for a new radio.
Hello, I am currently a Samsung Captivate user (which would suck without the developers here on XDA and the current ROM's), and I am looking to get a WP7 for my wife. I am very familiar with the OS and the SDK, but know nothing of the newer hardware available.
I was wondering what the general consensus was of the best available AT&T WP7 and if there would be any new phones in the next month or 2 expected so we should wait on getting this.
Also will any have a front camera for Skype and video calling.
most popular from AT&T in terms of windows phone is the Samsung Focus.
no word at present of any new hardware, but the mobile world congress is being held 14th-17th feb, which may or may not reveal more handsets (most probably not many if any).
and at present, there are no windows phones with front facing camera, and noone knows for sure when this will come about. and adding to that, skype have said that they have no plans for supporting windows phone.

Samsung has hinted heavily that they'll have a 4G WP7 phone at MWC. Not sure if 4G means LTE, WiMax, or HSPA+ though.
Focus
When I was visiting the ATT store as part of my research before buying a WP7 phone, I was told that the Focus, then the Surround, were the most popular WP7 phones and in fact the Focus was the #2 selling phone overall.

Verizon is LTE, Sprint is WiMax. No gsm carriers in the states have rolled out 4g yet, I don't think. AT&T will definitely be LTE, but it won't be online untill mid 2010, I believe, according to them.

If you go by the original definition, LTE and WiMax are NOT 4G. And if you go by the newer definition, HSPA+ is 4G... I don't know why people shaft T-Mobile in their 4G conversations when they have the most consistent and technically fastest 4G service in the US.
That being said, I do hope a HSPA+ T-Mobile WP7 is coming soon.

The SoC that they are rumored to add support for in the near future is the same as the G2 I believe, so I wouldn't be surprised if that's what is coming. AT&T also has HSPA+ now too though, of course.
I wasn't even aware that ATT had HSPA, afaik they were going to be rolling out LTE this year, while T-Mobile increased they HSPA+ to 42mbps...

Hello
It sucks being an european and to have a 4g/cdma phone because in my country (Romania) you dont have a cdma network
So as we all know the Thunderbolt has the same chipset as the Rezound so in theory it should be able to transform into a Global Phone.
My question is why didn't anyone do that and how i can make one myself if a dev dosent bother.
I feel it in my guts that this will work but i need some guidelines, or someone with actual knowledge to help me.

Thunderbolt doesn't have the hardware. Not possible.
and what hardware are you talking about?
Thunderbolt has a CDMA radio and an LTE radio. Global phones need a separate GSM radio to work in Europe. If it has an unlocked SIM, the Thunderbolt should work on any 700mhz band LTE network, but is incompatible with GSM on all levels.
Sent from my ADR6400L using Tapatalk
MDM 9600
Actually, the Thunderbolt has an MDM 9600 baseband chipset that supports Hspa and Hspa+ which is a technology that At&t and T-mobile uses for their data connections. So, I believe that if the LTE radio is backwards compatible with those frequencies of At&t or T-mobile that it might work. The thunderbolt has two antennas: one for strictly CDMA and the other for lte and backwards compatibility to gsm/hspa(+) from what I understand. From what I have read Verizon has just opted to not install the drivers to support the GSM/HSPA(+) side of things. That, and the MSM 8650 processor or other hardware in the Thunderbolt may not support it. Just because the modem supports GSM/HSPA(+) doesn't mean the phone will, but I do think that if someone really wanted to they could modify the thunderbolt to work on GSM. The may need more hardware, but I do not know.
I would post the link about the chipset I have, but sadly as a noob it will not let me.
P.S. Verizon allows you to log-in to your account and view the unlock code for the thunderbolts SIM yourself. You do not have to call them. I have not used another Carriers SIM in my Thunderbolt, but HAVE read about people who have in other threads. Verizon from what I understand and have read on other forums does not allow you to use USA SIM cards other than VERIZON'S own SIM. From what I have read, it only unlocks the phone to use foreign country SIMs only. From what I had read, once you use VERIZON'S SIM unlock procedures a NEW menu pops up in your network settings giving you the option to select to use GSM only. The same thread was speaking about the iphone 4s and the Thunderbolt and said that Verizon allows for both to be unlocked and used as World Phones. I will not know for sure until I see proof, but I do know that Verizon allows you to unlock the Thunderbolt's SIM to use on Foreign Networks.
The MDM9600 baseband definitely supports quad-band GSM. However, the RF transceiver in the Thunderbolt may or may not, and the power amplifiers definitely do not. You need all three in order for a mode & band to actually work on a device.
Not possible from a hardware point of view.
Where the heck are they and when are they coming? Carrier branded lte phones are big headaches and/or gimped compared to their unlocked unbranded gsm brethren. Any news on the horizon when these will start popping up?
...
I'd like to bump this thread, as my question is similar. I have gained a decent understanding of GSM technology over the years, but I have not kept up with the industry underworkings with LTE. Am I wrong in feeling like LTE is moving away from global standards, towards national- or carrier-specific technologies? I am a U.S. user who tends to buy more international phones than ones branded by AT&T (my carrier). Is there anything on the horizon which suggests manufacturers are trying to respond to LTE fragmentation? Are there radios which can communicate with more than LTE signal type? Are manufacturers/chipmakers looking into multiple-radio options? I invite anyone who understands LTE in the least to respond, please. Thanks!

Manufacturers just make the phones to the big corporations specs. Now when you refer to LTE fragmentation is it spectrum or frequency frag you are talking about? Using existing 3G frequency bands for LTE and more multiband devices is the cure for spectrum fragmentation.The problem of LTE and other services running on different frequencies in different regions has been a major headache for device makers like Apple. The company stopped promoting its new iPad as compatible with 4G networks in Australia after a local consumer commission filed a complaint with the federal court in March. Apple's newest iPad can connect only on 700 MHz and 2100MHz LTE bands, which are used in the U.S. and Canada. My Droid Razr running a custom ROM will pick up LTE/CDMA/EvDo/GSM/WCDMA frequencies with no problem. 4G LTE is overrated at best. I live 12.5 miles from our state capital and didn't get 4G LTE until a few months ago, before that it was 3g and that's it. Only in major metropolitan areas will you find 4G networks that are worth the price. AT&T, T-Mobile and Verizon all claim to have the largest network. Explain to me how 3 different corporations can make the same claim? That is simple, they brag about what they don't have just to increase their sales. I guess you could say it's a conspiracy against the people of this great nation who are being taken advantage of. We have the internet and all the knowledge of the world at our finger tips. Just do the research, I work in Information Technology and know how to research and find what I need to know. It brings to mind a favorite saying of mine and I quote" The blind are easily led, especially when they do not know where they are going".
I hope this helps explain the chosen topic.
I didn't realize until after I received it that the KB2000 was the Chinese variant. The one I bought said it was was GSM unlocked. I switched over to T-Mobile but have abysmal service where I'm at. The most I've seen from my house all the way to work (which is admittedly, in the boonies) is 1 bar, and most of the time it's just an "x." I had Sprint before which was pretty bad, but at least actually worked. I figured T-Mobile would be the best bet, as they're merging, but that was a failure.
Anyway, the listing says the phone is GSM unlocked and not for Sprint or Verizon, so is there no hope for getting this phone on one of the CDMA networks? I love the phone, but if I can't use it as a phone, I can't do much...
Ugh,
Doesn't look so great my friend.

Dang, that's not great. Thanks a ton for the help! I've somehow never seen that site, I've been using willmyphonework.net, which is.. meh.
It won't work on Verizon well (if at all) since it's missing band 13. So Verizon is out.
Theoretically it could work okay on T-Mobile since it supports bands 2/4/12 but "boonies" coverage for T-Mobile is trash in my experience. It's also lacking band 71 which travels furthest from the tower (realistically this probably won't make a difference if you already have super poor signal). Some phones on T-Mobile will get native Sprint signal now too- I noticed this behavior on my Pixel 3a XL but not on my OnePlus 8T KB2005. Certainly the KB2000 will only connnect to native T-Mobile. This is reserved for iPhones, Samsungs, Pixels I think.
AT&T might be worth a shot. It supports bands 2/4/5/17 and KB2000 is on AT&T approved device list https://www.att.com/idpassets/images/support/wireless/Devices-Working-on-ATT-Network.pdf 17 is the low band coverage (700MHz) just like Verizon B13 and T-Mobile B12. AT&T has better rural deployments too in my experience. It won't get 5G and you're missing bands 14,30,66 but 2/4/5/17 is enough to have a decent network experience.
First of all, wow, thanks a bunch for the help!

Saved up for the nice OnePlus, and I know people have said they're kind of "selling out," but they're still super root friendly and very open, so I was excited. I also knew I wanted to switch to GSM (been on Boost/Sprint forever, now), and I figured going to T-Mobile from Sprint would be my best bet, as I figured I'd have T-Mobile's coverage PLUS Sprint's, because of the buyout.
Then I read Sprint users can all fallback on T-Mobile, but not the other way around? Except for your listed "premium" models. And I also didn't figure the "boonies" service would be quite this bad; it's awful.
Other people around me say ATT is awful as well, pretty much only Sprint and Verizon are serviceable. Looking at the frequencies, it has no Sprint CDMA bands and with Verizon it only has one: BC0 (no BC1). I've read that 13 is Verizon's "main" LTE band, but how do we know this information? Is BC0 (800) better than BC1 (1900)? I know that *overall* with Verizon the service wouldn't be fantastic, but as long as there's connection in the boonies, that all I need, really.
