800 MHz Band - Sprint HTC EVO 4G LTE

Alright soooooo, the cell phone tower by my mouse is barely functioning right now, sprint says there's 2 tickets open, and that Data is at 0% capacity and voice is only at 68%. Anything below 96% is bad according to them, to make a long story short, I have no data, texts will not send, and making calls is a crap shoot. most the time you get the message that says all circuits are busy.
Seeing as there's no root for the ".3" firmware, please correct me if I'm wrong, I did the the *#*#info#*#* and changed my cellular band to 800MHz band and I'm now running on Verizon according to not roam control.
My question is...I know Verizon uses 800MHz for LTE, is this band also used for voice and text too? and why hasn't sprint taken advantage of the 800MHz band before the LTE rollout. AND How can verizon have LTE and CDMA both in 800MHz?

I got the same song and dance from Sprint, and eventually, after I complained enough, I got a free AIRAVE.
About 800 MHz, it might be like ssh tunnelling on port 22, in that these different protocols may be able to function concurrently on that band. Not sure.
Are your towers LTE? Mine will be after the upgrade in North Hollywood. At that juncture, Sprint may be forced to operate on the higher bands.

No mine are stillk evDo towers, I'm in Arizona so LTE is a while away. I wonder why sprint hasn't used 800MHz before like verizon has?

And by "Forced to operate on Higher bands", you mean lower right? because 800 is lower than 1900

Yes, that's what I meant, sorry. LOWER bands. Yes, I'm sleep-deprived... I admit it. =P

No problem! Also, do you know what sprint will do with the 800MHz spectrum? I know the box for my phone says it's able to connect to 800MHz CDMA

800mhz is currently being used by Nextel towers. Those towers are also being decommissioned, with the final tower being taken offline in 2013. 800mhz will be used for LTE only on sprint(if i recall correctly), so although this phone is capable of 800mhz CDMA, i do not believe it will be valuable asset as there will be no 800mhz CDMA broadcast.

As soon as the new Sprint LTE towers are up, I will be attempting to use a full spectrum analyzer, and remote performance and capacity planning tools to gauge overall health, bandwidth, etc.
I assume that security will be put in place to prevent such data and metrics from being culled, but it is worth a shot.
I will publish results here when the LTE towers are in. I'll know they are officially in production before Sprint drops a press release, as my handsets will actually work in my office without using an AIRAVE. =P

4g signal

I have upgraded my vibrant plan to 4g and I was wondering if anyone can make a zip for the 4g signal that will match the frobuntu donate theme I asked the developer for frobuntu if he could he hasn't yet so post it on that page if possible I hope he doesn't mind

Vibrant 4g plan?
4g plan?
Vibrant + sXe V3.1 + OCLF
The Web plans were renamed they are still the same at T-Mobile you will only recieve full 4g speeds in 4g areas and on 4g phones.
How do you get a 4g plan on a 3g phone? I did notice in the Flashable Stock JK6 rom sombionix posted has both 3g and 4g icons. I thought you had to have a 4g phone to get 4g service.

I'm thinking the samething. 4g would be based on hardware radio and 4g connection.

You could change the icon to say 10g and you would still never get 4g speeds. Vibrant doesn't support that speed.

Vibrant hardware only supports up to 7mb/s
Fear the beard...
Technicly Speaking Vibrant does support so Called "4G" speed, since its not 4g on Tmobile, 4G its either Wimax (sprint has it) or LTE , T-Mobile has only HSPA+ , so whats HSPA+ its the Same HSDPA network which is Considered to be 3.5G, and since its HSDPA I got speed on Vibrant in Alabama 4.7MBit Per second on speed test, 3G Doesnt support that speed because 3G is UMTS its max 3.6MBit per second, New HTC G2 and HTC Evo 4g or whatever tmobile has at the moment calling "4G" phone doesnt Support LTE or WiMax, it supports HSDPA with 14.4MBit per second speeds, Vibrant works on same Frequency and same HSDPA with 7.2Mbit per second which is Twice less. So Basicly if lets say you live in city where VIbrant can get 3MBit per second , you 4G phone will get 3Mbit as well, but if you live in city where you can get 7Mbits per second on your G2 or 4G phone you will get same speed on Vibrant too. Just icon will not be changed. The trick Tmobile using to let you think you are on 4G instead of 3.5G is by Setting HSDPA network icon as H or 4G instead of regular icon 3G , when phone goes to UMTS it shows 3G, when it goes to GSM it gets to E and so on . So its just Icon nothing more, stop worrying about Icons , what really matters that Tmobile doesnt offer speeds of more than 5Mbit anywhere yet. Maybe maximum 6Mbits if you live close enough to HSDPA Tower. (like 10 feet away). And this speed Vibrant will hold on ease. So Main Point and Bottom Line is ANY Phone that supports HSDPA Network with up to 7.2Mbit per second will be receiving Maximum Tmobile Speed which is avarage 3-5Mbit per second depends on your location and dont mind if it says 3G and not 4G speed on your phone will be Exacly the same since its Same Network HSDPA. Hope it clears everything since its Just Marketing Trick nothing else.
Oh forgot to mention if you have 2 phones in your hand both Vibrant (or any other 3.5g phone) and 4G phone from tmobile , both on same tmobile, sometimes difference can be in speed because it also depends on Antena strenght on your phone, some phones have better antena thats why they get more singnal but difference is not big at all. And if you ll stand next to HSPA+ (HSDPA) Tower with both Phones in your hands , Speed will be IDENTICAL. But on NEW phone it will show 4G even if its on same 3.5G (HSDPA or so Called HSPA+ how tmobile likes to call it) So 4G phone is basicly has overclocked Icon and Vibrant downclocked icon which Displays 3G , I think both phones would be correct if they will show H or 3.5G icon. But if they both will show H or 3.5G who will buy 4g phone ? and why the hell Tmobile then shows comercial of 4g ? Tmobile doesnt want you to know the truth, they want you to believe that by Buying 4G phone (which costs more) you will get better speed which is a big fat lie. Otherwise you will not fall for it and stick with your 7.2MBit/s HSDPA phone and it doesnt matter if its Vibrant or G1 or anyother phone. If you want to check which phones support 7.2MBit on HSDPA or 14.4 and see phones that have Wimax or upcoming LTE check gsmarena.com
these are all 3.5G Phone available for all carriers at the moment notice MyTouch 4G on tmobile in the list ) http://www.gsmarena.com/results.php3?sName=&idMaker=0&chkHSDPA2100=selected&idAvailability=0&YearAnnounced=0&nPriceLow=0&nPriceHigh=0&idCurrency=0&idFormFactor=0&idDualSIM=0&idQwerty=0&HeightMax=0&WidthMax=0&ThicknessMax=0&WeightMax=0&idOS=11&idDisplay=0&idDisplayRes=0&fDisplaySize=0&idDisplayTech=0&idTouchscreen=0&idAccelerometer=0&id35mm=0&idCamera=0&idCameraFlash=0&idVideoRecorder=0&idSecondaryCamera=0&idExpansionCard=0&idGPS=0&bWLAN=0&bEDGE=0&bGPRS=0&idBluetooth=0&bIR=0&bEmail=0&bWAP=0&bJava=0&idRadio=0&bMMS=0&idRingtones=0&sColor=&StandBy=0&TalkTime=0&sFreeText=
Abriviation of HSPA is High Speed Packet Access, Which has 2 types, HSDPA (High Speed "download" Packet Access) and HSUPA (Upload speed)
Niether WiMax nor LTE are 4G, apparently.
They're just faster than what has gone before, but still slower than HSPA+, if memory serves.
Regardless of all that, 'upgrading' your plan to "4G" is stupid with a Vibrant, b/c it doesn't support anything resembling said *G.

the mytouch 4g gets better speeds. Side by side with my friend's mt4g i get 1.5mb max he gets 2.7mb max.
Ok WiMax is slightly Faster than HSDPA for sure (dont mind spint since they USE 3g not WIMAX Network) LTE Can hold Speeds up to 60MBit per second in most countries Minimum speed is 20MBit per second, WiMax can hold up to 20Mbit as well in Most european countries it gets 9-10Mbit Per second. And 3MBit in bad locations. So Officially... 4G its LTE 2 or Wimax 2 which are next generations of Wimax and LTE. But here how it goes, GSM first Geneneration is GPRS, then second Generation is EDGE , then goes UMTS network for phones with Sim Cards, And EDVO-A (same 3g) for CDMA phones. Now Next generation which is 3.5G Its HSPA (HSPA+ its not a special network its still HSPA ) So with Maximum Download Speeds HSDPA 14.4Mbit per second, and upload HSUPA 5.72MBit. Now lets get to 4G , or I preffer to call it PRE-4G But after 3.5G. Main Candidate is LTE! Since I never saw Speed on LTE Network anywhere in europe Less than 14Mbit per second and Maximum speed I saw was 68mbit per second or so with some Europe Mobile Provider. Now lets go to WIMAX. Its not even Mobile network such as GSM or UMTS or HSPA or LTE. Its more of Next generation of WIFI. It works and acts as wifi more than Mobile network but with Big difference. Wifi N Routers for example can work up to 300feet range maybe even little more. While Wimax can work up to like 30-50mile RANGE! So basicly Internet Providers just Use those Special Routers with Huge Antena so you will get signal in your city And trasmit very big download and upload speeds. So thats Wimax. its like Extended range WiFi nothing else. So basicly if Sprint even has WiMax they are acting more like Att or Verizon DSL with speeds up to 3mbit per second plan and just trasmit it over WiMax to you if you are in range ofcourse. If not you will use just EDVO-A (3g)
So Basicly 2g is GSM or CDMA, 3g is UMTS or EDVO-A, 3.5G is HSPA, Pre4G or 4G Candidate is LTE at the moment. And real 4G will be LTE2. Wimax is just Next generation of WiFi.

Well try to run tests like 10 times , and calculate avarage speed. I had problem with my Vibrant that I got 2.8Mbit one time on 1 spot. Its called Latency (lag) then I reran speedtest and it showed 4.5mbit per second. So does it Mean my "3g" phone faster than his 4g ? No since his phone capable of holding 14.4mbit per second on HSDPA while my only 7.2Mbit, But it could mean one of two things, 1 your phone is deffective antena or software for antena or HTC has better Antena and or better Firmware which makes antenna signal is better. Tmobile just doesnt provide good speed in your area. And when you ll run same test on same spot (do not hold sides of your since it can lose signal Antena is on the side of the phone you are blocking it) The proper way to test you and your friends phone is. Put both phones on table make sure distance will be at least few feet from each other so they will not block frequencies of each other. And press SPEEDTEST app same time. And run test about 5-10 times, if your phone will still show slower speed, try to change places put your phone on his place and his on yours. And if still you will get slower speed I suggest you go replace phone since you got it with deffective antena or firmware. But I bet his phone works with Froyo and Vibrant doesnt even have official froyo yet that may fix antena signal. I think vibrant has same problem as Iphone 4 had. But iphone 4 fixed it with 4.1 Firmware which updated baseband and Vibrant didnt have any fix. Anyway I got 4.7Mbit per second driving my car on Highway in Alabama using Stock Android 2.1 JK6. I didnt test speeds in that place anymore sitting on Axura 2.0.6 but in Miami, FL I get mostly 2.5-3.6mbit per second. But im sure if you ll go with your friend to T-Mobile HSPA tower (if you know the location) and put your phones to test you will get same speed. Tmobile doesnt offer bigger speeds than 6mbit Im sure of it. So the phones are equal at the moment.
If you don't like the option for the 4g keep it to yourself but for you idiots I have 4g coverage on my vibrant I upgraded it a few weeks ago and it shows up on my bill as unlimited 4g web so call t-mobile and ask them to upgrade your plan, making statements that you fail to research is ignorant and you just look stupid

NEW YORK (CNNMoney.com) -- You've seen the 4G advertisements from T-Mobile, Sprint and Verizon, bragging about a much-better wireless network with blazing fast speeds.
Here's the secret the carriers don't advertise: 4G is a myth. Like the unicorn, it hasn't been spotted anywhere in the wild just yet -- and won't be any time in the near future.
The International Telecommunication Union, the global wireless standards-setting organization, determined last month that 4G is defined as a network capable of download speeds of 100 megabits per second (Mbps). That's fast enough to download an average high-definition movie in about three minutes.
None of the new networks the carriers are rolling out meet that standard.
Sprint (S, Fortune 500) was the first to launch a network called 4G, going live with it earlier this year. Then, T-Mobile launched its 4G network, claiming to be "America's largest 4G network." Verizon (VZ, Fortune 500) plans to launch its 4G network by the end of the year, which it claims will be the nation's largest and the fastest. AT&T (T, Fortune 500) is expected to unveil its 4G network next year.
Those networks have theoretical speeds of a fifth to a half that of the official 4G standard. The actual speeds the carriers say they'll achieve are just a tenth of "real" 4G.
So why are the carriers calling these networks 4G?
It's mostly a matter of PR, industry experts say. Explaining what the wireless carriers' new networks should be called, and what they'll be capable of, is a confusing mess.
To illustrate: Sprint bought a majority stake in Clearwire (CLWR), which uses a new network technology called WiMAX that's capable of speeds ranging from 3 Mbps to 10 Mbps. That's a different technology from Verizon's new network, based on a standard called Long Term Evolution (LTE), which will average 5 Mbps to 12 Mbps.
Seeing what its competitors were up to, T-Mobile opted to increase the speed capabilities of its existing 3G-HSPA+ network instead of pursuing a new technology. Its expanded network -- now called 4G -- will reach speeds of 5 Mbps to 12 Mbps.
No matter what they're called, all of these upgrades are clear improvements -- and the carriers shelled out billions to make them. Current "3G" networks offer actual speeds that range from between 500 kilobits per second to 1.5 Mbps.
So Sprint and Verizon have new, faster networks that are still technically not 4G, while T-Mobile has an old, though still faster network that is actually based on 3G technology.
Confused yet? That's why they all just opted to call themselves "4G."
The carriers get defensive about the topic.
"It's very misleading to make a decision about what's 4G based on speed alone," said Stephanie Vinge-Walsh, spokeswoman for Sprint Nextel. "It is a challenge we face in an extremely competitive industry."
T-Mobile did not respond to a request for comment.
One network representative, who asked not to be identified, claimed that ITU's 4G line-in-the-sand is being misconstrued. The organization previously approved the use of the term "4G" for Sprint's WiMAX and Verizon's LTE networks, he said -- though not for T-Mobile's HSPA+ network.
ITU's PR department ignored that approval in its recent statement about how future wireless technologies would be measured, the representative said. ITU representatives were not immediately available for comment.
"I'm not getting into a technical debate," said Jeffrey Nelson, spokesman for Verizon Wireless. "Consumers will quickly realize that there's really a difference between the capabilities of various wireless data networks. All '4G' is not the same."
And that's what's so difficult. The term 4G has become meaningless and confusing as hell for wireless customers.
For instance, T-Mobile's 4G network, which is technically 3G, will have speeds that are at least equal to -- and possibly faster -- than Verizon's 4G-LTE network at launch. At the same time, AT&T's 3G network, which is also being scaled up like T-Mobile's, is not being labeled "4G."
That's why some industry experts predict that the term "4G" will soon vanish.
"The labeling of wireless broadband based on technical jargon is likely to fade away in 2011," said Dan Hays, partner at industry consultancy PRTM. "That will be good news for the consumer. Comparing carriers based on their network coverage and speed will give them more facts to make more informed decisions."
Hays expects that independent researchers -- or the Federal Communications Commission -- will step in next year to perform speed and coverage tests.
Meanwhile, don't expect anyone to hold the carriers' feet to the fire.
"Historically, ITU's classification system has not held a great degree of water and has not been used to enforce branding," Hays said. "Everyone started off declaring themselves to be 4G long before the official decision on labeling was made. The ITU was three to four years too late to make an meaningful impact on the industry's use of the term."
I got 4g speed on mine after my upgrade and my signal went from 3g to now says H.

Hspa+ vs. LTE

I'm pretty confused. I'm wondering what's the difference between hspa+ and LTE? I know verizon currently has LTE and At&t has hspa+ but what is the difference between the 4g speeds , I mean 4g is supposed to be (100 mbps ) right? Also why does At&t call their 4g phones , "4g" when they are going to LTE for 4g speeds so doesn't that mean hspa+ phones are a ripoff, and you wasted you're money on a 4g paperweight?

hspa+ is fake 4g (though so is the current LTE, but hspa+ is just 3g hspa on steroids, not a new standard). On my HTC Thunderbolt with Verizon, I get anywhere from 16Mbps to 30Mbps, depending on where I am for LTE.
If you want to know more about LTE, I would suggest doing a search around one of the Verizon phone forums with LTE, such as the Thunderbolt, Charge or Bionic.
LTV vs HSPA+
I guess it depends on the flavor of each you are referring to, the backhaul the given provider attaches to their network, and the amount of spectrum they have. Comparing a given HSPA+ site to a LTE site and assuming same backhaul and same amount of spectrum, I think LTE pushes more bytes more quickly than the HSPA+ [21Mbps/14/7] that AT&T has deployed. However, T-Mobile is deploying a flavor of HSPA+ that is 42Mbps. Real world speeds of that network have been up around 30Mbps with the Rocket 3.0 which puts it on par with some of Verizon's LTE real world peak speeds. I don't know if AT&T has stated if they will go to that version of HSPA+ or not, and even if they do I am not sure they have enough spectrum to do that (without buying T-Mobile's). I would say LTE is better, and once AT&T, Verizon and Sprint roll out LTE Advanced with and VoLTE, that will be the best. As far as 4G, that organization that decides what is 4G (which by the way has changed it's mind at least once) says they want 100Mbps mobile and 1Gb fixed as the speed standard for 4G speeds. Of the HSPA+ phones I have played with in stores or owned by friends, I have not gotten one to break 11Mbps yet, and they generally seem to sit around 5.

[Q] Why doesn't Sprint keep Wimax and do LTE on E4GLTE??

Just wondering why Sprint doesn't continue to use Wimax on devices like the E4GLTE? With GSM carriers they're incorporating 3g along with HSPA+ and rolling out LTE (AT&T), wich is great because between all 3 options you should be able to get some awesome data speeds pretty much all the time. Wouldn't it be great if you lived in a Wimax area with LTE you could fall back on one or the other depending on wich had a stronger signal. Im just wondering why Sprint is not going this route. With all of the reviews of the E4GLTE the one resounding fact is that there is currently no LTE anywhere and 3G speeds are horrid. It seems like keeping Wimax and using it when you can would have been a good option, at least temporarily. Any ideas?

Well...umm...
1. Wimax requires a different radio. LTE is built into the CPU, so you'd have to have a separate chip for wimax.
2. Wimax sucks. Its only claim to fame is that it was the first 4G available. Building penetration is crap.
3. Having both in the phone would cause power drains like you wouldn't believe.
4. Sprint is shutting down Wimax to focus on LTE. I imagine the expense of keeping both running is pretty high.
Just sit back and be patient. LTE will be there soon enough. Or stick with your current wimax phone and wait until you have LTE to upgrade. If your main reason for the upgrade is LTE then you should reconsider your options.
Remember HD DVDs? and BluRay? Which one is still around?
Also, Plasma, DLP, LCD, LED technologies in TVs. Its a 'technology war' thing.
WiMax and LTE were two technologies like this. LTE won as BluRay did and to keep up, Sprint has to rebuild their network. Also, the reasons stated above in smw6180's post.
I actually could care less about which one I have as I'm on wifi most of the time. This was truly "Just a question". But isn't HSPA+ a dead technology but its still being included into GSM devices even the ones with LTE. Im just wondering why it is and Wimax isnt. And where I'm at Wimax is awesome I get anywhere from 4-8mbs when im on it.

HSPA+ isn't dead at all. The rest of the world uses it. Try a T-Mobile or At&t phone on HSPA+ 42.

I most certainly would love to. I hope the International GS3 has HSPA+ and I can get it unlocked and use it on T-mobile. I miss GSM but dont really care much for ATT and I read somewhere T-Mobile is revamping there prepaid data plans, so hopefully I will get to try it out.

Totally agree, and number "2" is definitely a must for me I have tested it here and wimax well you said it, and more now is adding both radio and battery on-board will give a A+ with power as well

GSM carriers include 3g, HSPA+, and LTE because HSPA+ is an extension to 3G, using the same radio. Therefore there are still only two radios in the device: WCDMA (which is 3G with HSPA+) and LTE. Sprint's doing the same thing - their equivalent is having 1xAdvanced, EVDO rev B, and LTE.

Great answer my friend. I completely understand now. I didn't know what 1x advanced and EVDO rev B were before. Now are any of those capable of the speeds HSPA+ is though?

No, HSPA is in its own class of speed, CDMA doesn't have anything close to it. And it's not like sprint's network could handle much anyway, since there's plenty of dirtbags abusing the Unlimited service.

LTE Frequencies

Simple question: why is Sprint starting to roll out one spectrum of LTE now, and then changing it to a different one later (2013 and on)? Why not start off with the superior one that penetrates walls better to begin with? Any advantages to the frequency currently being built up?

They're starting on 1900 then adding 800 not replacing 1900. Both will be used LTE in 2013. Also they can't use 800 till Iden is off it. IDEN on 800 won't be dead till 2013. Sprint is decommissioning iden towers now in preparation for the shutdown. They are trying to migrate people over to sprint direct connect which uses the cdma network for direct connect.

This site is the best for sprint LTE info...

okay, this will be fun to try and explain. first of all, my source is this:
http://www.hightechforum.org/low-versus-high-radio-spectrum/ and logic
Data is sent through wavelengths across different frequencies. Basically, the higher the frequency the higher the capacity and the lower the frequency the higher the coverage.
Sprint's WiMax runs on 2500 MHz, which explains the crappy coverage. Verizon has great LTE coverage because it runs on 700 MHz. The reason Sprint went with the higher frequency was probably to meet the demands of an "unlimited data" community because it would have a much much greater capacity than the 700 MHz spectrum Verizons running. This is also why cell providers with much better coverage (ones near 1000 MHz) have to throttle so hard and limit the amount of data usage: because they have much lower capacities (bandwidth) to share with their consumers in those frequencies.
Of course, cell companies dont only use one band of the spectrum. They send it across one low and one high to accomodate both capacity and coverage (i believe Verizon uses 700 and 1400 MHz). What david279 said is correct, Sprint will use both 800 and 1900 MHz eventually, so its gonna have a great LTE network.
So to answer the original question, Sprint was probably confident to launch the 1900 MHz frequency by itself because it is a good medium. 700 and 2500 MHz are at the ends of the spectrum. The best speed results would be more towards the middle. Instead of having great coverage and LTE speeds as low as 1gb/s with the 800 MHz frequency, or poor coverage with WiMax speeds of ~3gb/s (about what i've gotten) with the 2500 MHz frequency, Sprint's settling with good coverage with LTE speeds of Xgb/s (higher than 3, for sure) with the 1900 MHz frequency with coverage later to be improved once the 800 MHz frequency is included
So be ready in 2014 to buy the EVO 4G LTE+, since our phones can't pick up the 800.

Could that be fixed by a software update, or is it strictly hardware related?

Strictly hardware. It's also one of the reasons lte roaming isn't in the cards.

Verizon only uses 700mhz for their LTE Network, Not 1400mhz. I believe 1400mhz is a government used band. Also, Sprint cant use 800mhz until the 3GPP and FCC clear that band for LTE use. On top of that Clearwire will be doing TD-LTE on 2500, which will have international roaming compadibility in europe, and yes Sprint did sign a deal with clearwire so they can use that band as well for their customers.
TD-LTE is LTE used on a spectrum that does not have a upload frenquency only download.
FDD-LTE is normal LTE used with a frenquency that has both download and upload.

1400 MHz is allocated for WMTS (Wireless Medical Telemetry) as primary user, secondary is non-medical telemetry. 1400 MHz was military until 1999 when it was "sold off" to the highest bidder.

And one of the greatest addictions as well. I own a fairly large (though shrinking) collection of all things radio.

No LTE roaming?

No LTE roaming? Does that mean the EVO 4G LTE can't make or receive roaming calls, or just that it won't use the LTE network for them?
While I'm asking newbie questions, I gather the switch to LTE doesn't make Sprint phones (except the iPhone & one Motorola phone) usable in foreign countries, even countries with LTE networks. Is there any way to make it work overseas (without major surgery)?.
I'm probably going to get this phone when I upgrade, but it would be nice to be able to use it when I travel. International functionality is the only reason I'm still slightly tempted by the iPhone. Well, that and the boffo camera software on the iPhone.

only the lte is limited to the sprint network. you can still use the phone in countries that use the same cdma network as sprint. plug in the country you'll be going to in that link - if it says cdma, you're probably ok. But if international roaming is important to you, this probaly isn't the phone to get (depending on where you go, anyway).
CDMA HSDPA and LTE
How can ATT use LTE Band V2,17,4 Etc. which is 700, 1700, 1900 if other carriers are using those bands. I don't see anybody updating the Wikipedia from day to day with who has what. I see that the Chinese manufacturers are not producing phones for the US carriers except for a few high end phones like the Oneplus One. Is something going on that only Samsung seems to care about, producing a phone with 6 Bands or are the manufactures just waiting for the dust to settle? Don't you agree that a user who buys their phone wants to be able to switch carriers if they move, allowing for more freedom, or what ever reason, should have a phone that handles multiple frequencies. Most of the newer models coming out of china are set for TD SCDMA in their county only and have eliminated WCDMA altogether in those phones. Shopping around is much more difficult because allot of these vendors say little about signal compatibility on the web sites selling these phones.

Sprint LTE on Verizon or Others?

Shot in the dark here. I know i was able to modify my PRL on cdma so that my phone will work in areas with verizon coverage, but not sprint, i even get 3g. How does LTE work as far as directing to specific towers, and would it be POSSIBLE to configure anything in the evo LTE to get LTE coverage in areas such as chicago that have verizon LTE, but no Sprint LTE Coverage.
No because Sprint and Verizon run on two different LTE spectrums, Sprint uses 1900 Hz bands and Verizon uses 700 Hz bands
