I found an interesting article about radios and LTE connections. The Radio Performance Disparity of the Galaxy Nexus on GSM and CDMA - Mobile Central - Binary Outcast
I have the oppurtunity to either go with ATT or Verizon. The article makes it seems that GSM is a better bet for LTE phones especially in areas with poor reception. I am hoping people can provide insight/comments on LTE phones for GSM and CDMA carriers and the article.
The Radio Performance Disparity of the Galaxy Nexus on GSM and CDMA
The Samsung Galaxy Nexus. It's Google's flagship phone that is designed to complement the Android 4.0 “Ice Cream Sandwich” operating system software. With high end specifications (for 2011) and highly optimized software, the Galaxy Nexus is supposed to show off what Android can really do without any interference from carriers and OEMs. However, that wound up not truly being the case in the United States with the CDMA/LTE variant for Verizon Wireless and Sprint.
By and large, the CDMA/LTE variant sold by Verizon Wireless and Sprint is the same as the original HSPA+ model that is now sold by Google on the Play Store (at least in terms of hardware). It has the same CPU, RAM, NFC chip, screen, cameras, etc. The only hardware difference is the cellular radio structure.
The original UMTS HSPA+ model uses an Intel XG626 baseband modem that is connected to an antenna structure that supports quad-band GSM and penta-band WCDMA for global usage. For Americans, it means that it works on the HSPA+ networks for both AT&T and T-Mobile USA.
The CDMA/LTE variant uses a VIA Telecom CBP7.1 CDMA2000 baseband modem, connected to an antenna structure that supports dual-band CDMA2000. The Sprint model adds another CDMA2000 band that is exclusive to Sprint. Both CDMA/LTE variants use a Samsung CMC221 LTE baseband modem, but the Verizon Wireless variant is set up for LTE band class 13 (Upper 700MHz C block), while the Sprint variant is set up for LTE band class 25 (U.S. Extended PCS, also known as PCS+G). The Verizon Galaxy Nexus has a user-accessible SIM card slot while the Sprint one does not.
While the Intel (formerly Infineon) baseband used to be troublesome on AT&T's network (as many iPhone users that didn't own an iPhone 4S can attest to), the latest generation of basebands work fine on both AT&T and T-Mobile. With 3GPP Release 7 support, it has a maximum downlink throughput of 21Mbps while it has a maximum uplink throughput of 5.76Mbps. In general, the Galaxy Nexus works very well on AT&T and T-Mobile.
However, it isn't the same for the CDMA variants of the Galaxy Nexus. The VIA Telecom CDMA chip is notorious for weak performance. Other notable devices that use the chip are the Samsung DROID Charge and the Samsung Stratosphere. Searching on the web about these devices turns up a lot of complaints about CDMA service quality with these devices.
Jason Perlow of ZDNet experienced more than his fair share of issues while trying to live off of the 4G LTE connection his Galaxy Nexus provided. But he was trying to live off of 4G LTE, not CDMA2000. So why was he affected? Well, the truth is, CDMA/LTE devices require both radios to be active and connected. Not to mention, network authentication and feature provisioning actually goes through the CDMA system, not the LTE one.
The bridge between CDMA2000 and LTE is rather brittle and is prone to failure, because LTE wasn't designed to be bridged with CDMA2000 like that. It was intended to be installed alongside GSM and WCDMA networks, and it handles it a lot better with those networks. So when something goes wrong in the rather terribly buggy CDMA system, the whole phone can and usually does fail. If Verizon Wireless had upgraded the CDMA2000 system to UMTS HSPA+ like most other CDMA2000 carriers across the globe, it would have avoided dealing with this problem.
Also, the CDMA/LTE Galaxy Nexus lies to you (at least, it does now). Originally, the “bars” that indicate signal strength would actually indicate the signal strength of LTE if it was connected to an LTE network. When everyone started complaining about how weak the signal was compared to the Motorola DROID RAZR and Motorola DROID Bionic, Anandtech investigated. It turned out that the signal strength was actually accurate, and that LTE signals are incredibly weak. Previous devices used the CDMA signal strength to determine how many “bars” of signal you have. The Galaxy Nexus did not. It used the LTE signal strength when it was connected to LTE, and the CDMA signal strength when it wasn't. Verizon Wireless issued an update shortly afterward that changed the behavior to match older LTE devices. Newer LTE devices do the same as well.
Combining the fact that the Galaxy Nexus has to work incredibly hard to maintain an LTE signal with the fact that the CDMA2000 radio is horrible and has a difficult time holding onto the connection will lead anyone to the conclusion that it is a recipe for disaster. Is it any wonder why Jason Perlow and many others have so many problems with the CDMA/LTE version of the Galaxy Nexus? Not really.
Of course, this is excluding all the issues with timely updates that Verizon Wireless has caused for Galaxy Nexus owners. Including this issue just makes the problem worse. There are ways to work around some of the issues, though some workarounds will result in permanent degradation of performance. However, it doesn't mean anything if it takes forever for anyone to get any updates that implement them.
In the end, I really can't solidly recommend the CDMA/LTE version of the Galaxy Nexus to anyone. Nor can I recommend any CDMA2000 device that uses a VIA Telecom CDMA baseband modem. The pitfalls just make it a bad experience for everyone.[
Will the snapdragon S4 chip from Qualcomm help with this issue?
Techno Buffalo has an article about T-Mobiles transition to LTE and a T Mobile person stated that their enhanced backload will help T Mobile's LTE. will this help AT&T's LTE Too? http://www.technobuffalo.com/news/w...backhaul-is-the-key-to-a-users-4g-experience/
Here is another article talking about the challenge CDMA has with LTE when the LTE signal is weak

small error?
Hey didn't have time to read what you wrote but gsm is 2g and wcmda is 3g and 4g and LTE is also 4g so what you wrote did not make much sense GSM WCMDA and LTE are 3 different types of radios and here is a tip lo let people help you faster dont add more to what you wrote edit it instead because now it looks like 3 people already helped you
thanks if it helped :good:
For me this is highly theoretical. I recently moved from Dayton, Ohio to Kingsland, Georgia with a Verizon Galaxy Nexus (CDMA). In both places, if I allowed the LTE radio, the phone would get too hot to handle comfortably, and 3G isn't that great either. But in my neighborhood, there is no AT&T or T-Mobile data signal at all. That severely limits practical choices.

As usual, a major phone maker from Asia is screwing over USA, by disabling US carrier compatible LTE bands in their flagship phone series. If anyone from US, or other parts of the world, left in the cold by Asus purchased this phone and would like to try this LTE unlock and report the results - that would be very much appreciated.
If anyone knows of an online store, which took the liberty of unlocking US compatible LTE bands (T-Mobile: 2,4,12, AT&T: 2,4,5,17) in Zenfone 3 Ultra - please post the link to the store.
Will Asus make a separate US version and sell it here, or will this phone be international only? I'm in the US on AT&T and would certainly like LTE capability, but I've been buying overseas phones for a while now and HSPA+ is certainly fast enough for my needs.
If Asus isn't planning on a US version i'll just get the international one...

Just get a Mi Max, it's cheaper. My friend picked me up a 4gb/128gb version when he was in China for $313. I don't see a reason to spend top dollar on the Zenfone 3 if it won't support LTE here. I'd love to see Asus support LTE here but it's a shame they always disable the US LTE bands.

I heard that the Mi Max only supports some of the T-Mobile bands so you won't get full LTE (only HSPA). Do you know what network your friend uses his on and if he gets full LTE?

None of these phones support any LTE bands in the US. You'll only get HSPA+ or 3G. My thought is why pay 400+ for a phone with no LTE capabilities here. My friend picked up the Mi Max for me, I own it.

you can consider huawei mate 8 for USA LTE support (ATT & T-Mo), it is however a 6 incher 'only' .. my only gripe is the kirin 950 SoC, while on par with other top-tier silicon in terms of performance, it is none the less huawei in house and they are not known for releasing source code, meaning no 3rd party roms and probably no upgrade beyond nougat ..

I purchased my Asus Zenfone 3 ultra (ZU680KL) from EBay (593.00 factory unlocked), thru Never -Msrp, out of Houston Texas, but I believe it's still the global version.
I purchased a Bring Your Own Phone Plan thru Cricket, which is owned by AT&T. So they use their towers. I have not notice any problems with getting 4g/Lte.
Getting very good call reception and internet download speeds thru Cricket. I have a HTC 10 that I gave to my wife. The download speeds are similiar on 4g with the HTC 10 and the Asus. Both phones have many of the same 4g/lte bands. Just a little faster with the HTC 10, which might be due to the HTC having a faster processor. Depending where I am at in my area, I can see the H+ changing to 4g up in the status bar of the Asus phone when driving. Consistent 4g speeds where I live here in WV. I am also not to far from an AT&T tower.
XDA has always helped me with valuable information over the years of many of my phone ownerships, so I hope this information helps.

Just so people aren't confused... 4G and LTE are 2 different things.
4G = HSPA+ and is around 5-10Mbps.
LTE can be 20-30Mbps and also has much less latency.
Most people are looking for LTE in the USA and these international phones only support 4G (Which is slower than LTE but works good enough for me)

Thanks for your comments. I accept mostly what you wrote for most companies definition of 4G and LTE. I was going by my carriers definition or interpretation of what they call 4G LTE and just 4G. The confusion is more from the caps on the data speeds various companies have. Because to me there is little difference between saying LTE and 4G LTE.
Cricket is the carrier owned by AT&T. They call their data speeds 4G and 4G LTE. AT&T caps Cricket download speeds at what they say is 4G LTE at 8Mbps and 4Mbps download speed cap for just 4G (Referenced from Crickets's website and from www.gottabemobile.com 6/21/2015 article on this topic).
However, my earlier remarks about my Asus phone was incorrect, due to Asus limitations on their 4G/LTE phones sold to individuals in the US, even though the carrier here might support some of the same 4G/LTE bands. It's an Asus thing and probably some others too. I'm probably only getting just 4G or less. My speed tests are only showing 3Mbps and a little better on download speeds on Cricket Wireless with the Asus Zenfone 3 ultra. But I was only getting on speed tests 4Mbps and a little better download speeds with my previous HTC 10 on Cricket Wireless. I have never even gotten close to Cricket's 8Mbps on my HTC 10.
At this point I'm ok with HSPA+ (It's what i've used for years now in the US with International phones)
I'm waiting for root to surface for this phone and then i'm jumping right in

Please do not confuse people with false information. HSPA+ is officially considered 3.5G connection type. Long Term Evolution (LTE) is defined as a 4th generation (4G) wireless connection standard. Those are official nominations, you can find through IEEE site, Wikipedia and many other reliable sources. LTE theoretical max speed are nowhere near 20-30Mbps figure you provided - they are *much* higher. There is also LTE-A (advanced), which is also 4G but doubles the LTE speeds, and the actual LTE speeds depend on the hardware and LTE category of the modem.

Apple calls HSPA+ 4G, Yes i know its not technically correct, but that's what most people associate it with.
LTE can go much faster then 30Mbps for sure, I used to get 60. But nowadays with all the people using it 20-30 is a reasonable average for what most people actually see. (The point is its much faster than HSPA+)
I only bring this up because folks ask if they can get 4G on these international phones (As not everyone is a phone nerd like us) What they are really asking is if they can get LTE on these phones and most of the time that answer is no.
Basically I want people to understand that we are talking about HSPA+ vs 4G LTE and how that relates to international phones.
Is that good?

Apple or any other hardware manufacturers, as well as phone carriers can deploy any marketing schemes they like and call the lousy HSPA+ "4G" all they want, but it won't make it true. Neither of them gets to decide, and "most people" don't get to decide either. For the record, I disagree that most people think HSPA+ is 4G - most know better, in my opinion. The international governing body for wireless standards gets to name wireless technologies, protocols and classify by generation.
If you want people to understand that HSPA+ is different from LTE then saying "LTE can be 20-30Mbps" is not the way to go, because that would achieve the exact opposite. Theoretical max HSPA+ speeds achievable by this technology are 168 Mbps down and 22Mbps up, so defining LTE as 20-30Mbps connection makes your LTE no better than mediocre HSPA+ link. Some FDD-LTE and TDD-LTE links, based on the utilized spectrum, currently go up to 450Mbps down and 150Mbps up. Theoretical limits are much higher and LTE-A is twice faster.
While your intentions seem to be good, that still doesn't excuse providing inaccurate information, while also saying you dont want people to be confused. Confused is exactly what people would be, if they believe the info in your post. If you want to answer a question "will I get LTE in US with this phone?" - a simple "No" would be much better answer than inaccurate information you provided to "eliminate confusion". Or you could say something along those lines:
"ZenFone 3 Ultra is a GSM phone, so only AT&T or T-Mobile in US could be compatible, because Verizon and Sprint use CDMA technology. AT&T's LTE network operates on bands 2,4,5,17 (recently forced to support band 12 as part of FCC roaming support requirement) and T-Mobile's LTE network operates on bands 2,4,12 (recently forced to support band 17 as part of FCC roaming support requirement). Asus ZenFone 3 international version on the other hand, support LTE bands 1,3,5,7,8,18,19,20,26,28,38,40,41 - do you see any overlapping bands besides B5? B5 is utilized by AT&T in limited number of US regions and even there you will get extremely spotty LTE coverage, because LTE bands operate in conjunction with each other and there are constant layovers and fallbacks between frequencies, based on towers proximity".

Hi!
I bought a Huawei Mediapad X2 7" display phablet last November. I used it for a month on Cricket and couldn't get good MMS service... I wouldn't get group texts or pictures... How is your Ultra doing in that regard (on Cricket)? No good MMS is a deal breaker for me... Also, the X2 came with Google and Google Play Store already installed. I am not a techie but asked a LOT of questions on xda and was walked through a successful setup (I learned a lot from other people's questions, too)... I don't root my phones... So I need good out of the box service. I have been looking for a 128GB Ultra just to compare prices to a 64GB Ultra. Have you seen any? I am waiting for the Lenovo Phab 2 Pro to be re-released but I really would love this Ultra, instead (if it works on Cricket the way I need it to)... Thanks for your time!

I have had no problems with Cricket on my Zenfone Ultra. MMS, SMS, work just fine. No problem with sending group texts and pictures. However, you will not get LTE on the Ultra, in the US. For me, the 64gb on the internal side with a 64 GB SD card, gives me plenty of space. Google and Google play came pre-installed on my Ultra. So far, I have received great service from Cricket on my Asus Zenfone 3 Ultra and my HTC 10. I love the music app, the audio wizard, and the stereo speakers. Takes great pictures. It's like having a 7 inch tablet with 4gb of ram and it's a phone. Due to the size, the music features, the picture features, the huge battery, I use this phone more than my HTC 10. The only down side that I have with this phone, is you can't get LTE here in the US and you can't unlock the bootloader yet. But personally, I was initially looking for a 7 inch tablet with 4gb of ram, stereo speakers, that also took good pictures and has a big battery. I ended up with the Ultra.
If screen size is important to you might look at the Xiaomi Mi-Max, it has 6.4 screen and nice specs. Also Huawei Mate 9 with a 5.9 inch screen with nice specs also.
Hope this helped some...

I'm only a junior member with limited experience with these technologies, But I am just a little confused with these previous comments in regards to these discussions on HSPA+, LTE, and even Wimax for that matter. Believe me, when I say that I still have much to learn on this subject. Just because HSPA+ is different from 4G, I was always under the impression from everything I've read, that they are all still labeled as 4G technologies, as defined by the ITU. With all the above, having wide variations in consumer speeds. Also, whether a certain phone manufacturer supports a particular LTE band is just part of the whole part of the 4G technology. (Information taken from, in part, from Android Authority and Tech Radar)

Phrase "HSPA+ is different from 4G" has no meaning. Those are not comparible things "HSPA+" is an abbreviation for wireless protocol name, and "4G" is a generic reference to 4th generation of wireless technologies, which include several protocols. it's like comparing TV weight to picture brightness.
Judging from the phrase "whether a certain phone manufacturer supports a particular LTE band is just part of the whole part of the 4G technology" I'm not sure you understand how things work. Since approximately 4 years ago, ALL major SoCs (system on chip) support Worldwide Global LTE, all 41 bands. Here is an example of Qualcomm's Snapdragon SoCs, scroll down to "Global Mode": https://www.qualcomm.com/products/snapdragon/modems/4g-lte . So, all major SoC manufacturers have been "supporting" ALL LTE bands for approximately 4 years now. Mobile device manufacturers, who partner with SoC makers like Qualcomm, or produce their own (i.e. Samsung: Exynos) control what LTE bands are actually enabled using modem's firmware, which is purely a software issue and can be changed at any time with NVRAM hack or firmware update. They decide what bands to enable based on the country the device is targeted for. Operating frequencies in each country are tightly regulated, because otherwise there are security issues, surveillance issues, interference issues (that's why they ask you to shut your phone down on a plane) and LTE frequency bands spectrum is divided to over 100 chunks, and each country/region are only allowed to operate on a specific, limited number of frequency bands. Therefore, any phone manufacturer, who wants to release wireless device with certain LTE bands enabled in a specific country, first must abide by the frequency bands international rules and then before they are allowed to sell and operate their device, their device must be approved by each country's wireless regulations governing body, which will thoroughly test the device, to make sure it meets all the required technical, safety and security standards. For example, that governing body in US is called FCC and in China it's TENAA. To sum up, what LTE bands each phone maker enables for which country, has nothing to do with being "part of the 4G technology".

If screen size is important to you might look at the Xiaomi Mi-Max, it has 6.4 screen and nice specs. Also Huawei Mate 9 with a 5.9 inch screen with nice specs also.
Hope this helped some...

Xiaomi Mi Max is a bit of an old news. This Xiaomi phone is the future. Same 6.4" screen size as Mi Max, but device size is comparable to 5.7" phone, not to mention numerous other innovations, such as ceramic body and audio transmissions via ultrasonic vibrations, instead of conventional speaker.
