When LTE dominates, will importing phones still be possible?

Importing phones is obviously possible now because tons of carriers all over the world share AT&T's GSM and UMTS/HSPA bands.
When LTE starts to become the dominant source for cell-phone signals (especially when Voice-over-LTE appears), will AT&T still share bands with the rest of the world like it does now?
In other words, will AT&T still have the advantage over Vzw and T-Mobile that early adopters of phones will be able to import them and use them months before they show up in the US? Or will the proliferation of LTE cause AT&T to suffer from the same problem from which Verizon suffers: You will ONLY be able to use phones designed specifically for the AT&T network?
I ask because right now I have AT&T and Verizon, and I have unlimited data on both. I'm going to be canceling one of them within the next week or so. Right now I actually prefer AT&T's service, and I love the fact that I can import phones that are not available in the US. But if the "importing phones" advantage of AT&T disappears, perhaps Verizon becomes the more desirable carrier for me.

You haven't read much about LTE, I guess. By conforming to the LTE standards, a multi-band LTE phone will be able to be as much of a "world phone" as a multi-band GSM phone. While there are some differences in frequency spectrums around the planet, there are many in common.
The allocated frequencies are 700 and 1700 MHz in North America; 800, 1800, 2600 MHz in Europe; 1800 and 2600 MHz in Asia; and 1800 MHz in Australia.
So, a quad-band LTE phone with frequencies of 700/1700/1800/2600 would get you coverage almost anywhere.
The end result is this: If the manufacturers want to make an LTE "world phone" just like they have in the past with GSM, they certainly can (within the laws of physics, if the antenna technologies will allow it). The same economics apply for the manufacturers, and possibly better - since there are a smaller set of frequencies with greater chance of coverage - and a greater market potential for a single design.
I suspect that with modern fractal antenna technology, this won't be a huge issue.

In North America, are the 700 and 1700 different carriers, or is it better for a phone to support both like the current att 850/1900?

Thanks. That was actually pretty helpful. But for instance, it is my understanding that AT&T runs in the low-700s, and Vzw runs in the high-700s. And Vzw has tentatively stated that its LTE phones will not be compatible with AT&T's. So I guess when you say they could make a multi-band LTE phone, it would need to cover "all of" 700 MHz for it to have both AT&T and Vzw compatibility.
In any event, does this favor AT&T or Vzw for future phones? My guess would be for at least the next several years, if not decade or more, all LTE phones will have 3G radios in them as well. And those 3G radios, just like today, are going to be GSM. So I guess you could start seeing phones world phones that are both quad-band GSM and quad-band LTE, and theoretically these would work on AT&T, but not Vzw.
Am I on the right path here? Do you agree that it seems likely at least until GSM/3G completely die (if ever), most/all LTE phones will continue to have 3G radios, and this would suggest that if anything, importing international phones will still be possible on AT&T but not Vzw?

Almost every LTE deployment other than VZW runs alongside an existing 3GPP (GSM) network and most all chipsets will natively support the combination. Therefore, I doubt you will see many devices without the UMTS radios. No one is turning their 3G networks off any time soon. Verizon will be one of very few sources for LTE devices WITHOUT any other GSM radios.
As for LTE frequencies, there are A LOT of them. What chipsets will support which radio combinations is still a subject of much debate. Don't expect full interop out of the box.

You can always import regardless
the only risk you face is all the different LTE radio bands that you might or might not get with certain phones

Does the Galaxy Nexus LTE version also support the Penta-Band GSM bands for international travel?
Verizon version = GSM + LTE?
Sorry I'm a noob at Verizon's ways.

Don't think so. Verizon version = CDMA + LTE. So it will only work in the US, on Verizon.

It's possible that the Verizon version has GSM/UMTS radios, it's also possible that it has those but are disabled somehow. We really don't know all that much about the LTE version of this phone, we don't even know the exact dimensions of it and what battery it comes with. So we'll just have to wait until it passes through the FCC or is released.

I do recall seeing a negatory on the world phone status in Verizon's inventory system. And I suppose there is still the option for dormant or disabled radios but I ain't holding my breath.

[Q] Devices from different countries get 4G band restrictions?

Are there any differences in the LTE support of N7105 bought in different countries?
Given that not all network providers support the same LTE bands, do the cellphones they sell get restricted to work only under their specific frequencies?
I am planning on buying a N7105 from TMN in Portugal, but I will be moving to the US for a PhD course after a couple months, and I would like my cellphone to not suffer any 4G speed losses due to connectivity restrictions in the device.
I have tried googling this, but could not come to any precise conclusion . Can anybody help?
Thank you in advance!

The N7105 has 800/1800/2600 MHz LTE capabilities, I believe. This is the same for every model sold.
On AT&T in the US, 3G will work just fine. I'm not sure you'll be able to use 4G, though, since they use different bands for LTE.
EDIT: Yes, AT&T uses 700 and 1700 MHz for LTE. The maximum you'd get on their network is HSPA+.

[Q] T-Mobile Refarm PCS/AWS HSPA+ Questions

So I spent all night going through threads looking for more information on this (probably had 20 tabs open ), and just want to make sure I understand everything correctly.
As I understand, they are moving the DC-HSPA+42 from AWS (1700/2100) to HSPA+21 (1900), but because there is no room for dual channel PCS can only support HSPA+21.
Moving HSPA+42 from AWS to PCS will free up the 1700/2100 spectrum for LTE support, which ultimately they will phase out support for HSPA+ on AWS and only have HSPA+ on PCS (or minimal HSPA+42 on AWS).
So how does this affect me and you who only have a T-Mobile S3 that some of us were told *WOULD* support LTE, but it's obvious now it won't .... well sounds to me like we are getting the short end of the stick. I've already noticed since LTE popped up in my area that my speeds have gone from 15-25Mbps to 5-15Mbps if that.
Can anybody please confirm what I said above is correct and I am understanding all of this correctly?
Does anybody know of any apps that you can use to see what frequency the phone is using to be able to tell if you're on PCS or AWS? Or maybe an app that shows which version of HSPA+? I tried a couple on the app store but most of those only would tell me UMTS(WCDMA)....
I was very happy with the phone when I first got it but now I almost feel shafted by T-Mobile who didn't add LTE support for the ORIGINAL G3 they released...which you can no longer purchase from them. Same specs and all, just with LTE support ... I mean come on wtf t-mobile.

You sound pretty close on most of it. I'll try to offer a better answer when I'm back on my computer where I can reference a few things a lot easier.

[Q] Why AT&T has support for more LTE bands?

I was looking at the tech specs for the new HTC One and T-Mobile has less support for LTE bands.
Is it just a matter of HTC referring only to the bands that matter to each carrier or is it actually a question of different radios.
I ask because apparently the Google Play edition follows T-Mobile's hardware (possibly to provide support for both US GSM carriers), and makes it a no deal for international customers that need support to other bands.

In the review on Engadget they say there are 6 different versions of the phone. It seems the everyone who got it early for review received the international version without US LTE support. These are the radios for the AT&T and T-Mobile versions.
http://www.engadget.com/2014/03/25/htc-one-2014-review/
GSM/EDGE (850/900/1800/1900) (All)
HSPA+
AT&T: (850/1900/2100) with HSPA+ up to 21 Mbps
T-Mobile: (850/AWS/1900/2100) with HSPA+ up to 42 Mbps
LTE
AT&T: (700/850/AWS/1800/1900/2600)
T-Mobile: (700/AWS)
I've been looking into it myself because I'd like to get the T-Mobile version and flash the GPE rom and it does look like the GPE is the same hardware as T-Mobile's copy.
I really hate how these companies make a bunch of different hardware configurations. They're obviously capable of putting all the radios in one device, LG did it for AT&T, T-Mobile, and Sprint with the Nexus 5. N5 on T-Mobile is my current phone, I'm still trying to decide if the M8 is a worthy upgrade.

Yes the lack of compatibility between the two carriers is extremely annoying. I have the Dev Edition of M7 right now and it irks me to no end that I am stuck with AT&T with it. I'd totally buy the M8 if it supports all the frequencies of the AT&T version PLUS AWS for HSPA+.
I travel overseas a lot and I am very disappointed that I get more usage out of my old Samsung Galaxy S2 than the M7.

So how does this translate for M8 bought from somewhere else but used on T-Mobile network. I have ordered the M8 from Amazon (Prime shipping FTW), but it does not mention LTE bands.
http://www.amazon.com/HTC-One-M8-Unlocked-Warranty/dp/tech-data/B00J3554KE/ref=de_a_smtd
If I assume all non carrier branded M8 are the same, would the Play store description be accurate?
https://play.google.com/store/devices/details?id=htc_m8
Play store description mentions "700 MHz, AWS", which is a match with the engadget article "T-Mobile: (700/AWS)".
Would flashing a different radio software allow getting past incompatibilities, or the hardware itself is set to specific bands.
EDIT:
Just noticed this note at the bottom of Play Store page:
Compatible with AT&T and T-Mobile in the US. Check with your carrier for details about coverage.

From quick research, T-Mobile will get LTE in 1900MHZ by "end of 2014". I think I need to ask around a bit on Amazon/T-mobile and research some more...

Someone with more knowledge of radios can probably give a better answer than me but, as I said earlier, at first glance it looks like the Play Store (GPE) version has the same radios as the T-Mobile version. There's also a YouTube video of someone using a T-Mobile sim in their Verizon copy and it worked although, according to the data in the Engadget review, I don't think data speeds are as fast as they would be with the T-Mobile specific phone, at least on HSPA+.

Verizon: (850/900/1900/2100) with HSPA+ up to 14.4 Mbps
T-Mobile: (850/AWS/1900/2100) with HSPA+ up to 42 Mbps

Verizon: (700/AWS/1800/2600)

These are the radios in the GPE version

Not sure, but maybe the data over there is not accurate? Even the Amazon M8 page for ATT version shows the same information.

This thread over on the M8 forum does not have much concrete info either:

The radio situation is indeed a veritable mess. I wonder if there are any real tech/cost challenges which limit the radio compatibility or is it just the carriers being evil. I assume a standard hardware chip across all devices will be easier and cheaper to put in, so it must be the evil carriers forcing HTC then.
I am somewhat banking on the fact that unlocked phones (the one on Amazon) are most likely to be GSM compatible. Must get in touch with Amazon customer care I suppose rather than ranting here.

The Anandtech review actually shows that the GPe version combines the best of AT&T and T-Mobile!
http://www.anandtech.com/show/7893/the-htc-one-m8-review
It should work for both carriers.
It is instead missing WCDMA 900 so not optimal if you want to use it in Asia/Europe.

I did see somewhere that the DE has AT&T radios and the GPE has T-Mobile but that really doesn't make a lot of sense. I trust Anand so I think they're probably the most accurate.

No, T-mobile version will work for AT&T but not for Verizon.

What a ridiculous mess! Carriers shouldn't dictate what bands the phone comes in and they should all just be released in ONE model for GSM and all carriers get it.
I understand needing special models for Sprint and Verizon but for GSM its getting ridiculous.

Even the tmobile version doesn't show the 1700 frequency. Isn't that a requirement to be fully compatible with tmobile??

AWS = T-Mobile frequencies
AT&T, Unlock, and Dev versions will work on T-Mobile.
LTE = YES
HSPA+ = Depends if you area has LTE or HSPA converted from AWS to 1900
2G = YES
T-mobile version loses spectrum for LTE due to spectrum deals and HSPA+ spectrum support.
Qualcomm charges to license spectrum for their radio chips. Also it requires more hardware to support more frequencies. There has to be give and take, and would you pay $900 for the HTC One if it supported more frequencies?

Really? Apple has all the bands in one model. $350 Nexus 5 has all the necessary bands. So it is bull that it costs more, they just screw up every time. By the way I use the unlocked model and enjoying the M8 but no excuse for not having a single gsm model.

Sorry I firmly believe Google subsidizes a bit of the cost for their phones. They are using the console model to generate revenue.
Apple devices have a premium cost compared to majority of the items out there and doesn't include how much they make from iTunes.
The T-Mobile version is cheaper than the other GSM models.

Ok I will give you one more example...Sony unlocked devices in Sony store cost same as HTC One and they have all the necessary radios to work perfectly on r T-Mobile and AT&T. It's not that hard you know if you want to do a single gsm model.
And no Google is not subsidizing $500 or something, may be little bit they take a hit on profits from selling hardware but in no way they are fools to subsidize huge dollars. Like T-Mobile was selling Nexus 5 for $500 or something? Which might be the actual price.

GS5 Europe Compatibility in the US

I'm not sure where I would post this exactly anyhow =p but I don't know much about antennas and such and what the US primarily uses for phone towers and 4g and all that. How well would the European version of the s5 work in the US? More specifically the G900K which is for Europe usage.
Some specifics for the euro s5:
Network:
LTE 800/850/900/1800/1900/2100/2600); UMTS (850/900/1900/2100MHz) ; GSM (850/900/1800/1900MHz)

1st, this should have been posted in the Samsung Galaxy S5 q&a forum. It looks as if the radios are similar, but you cannot flash roms or any other software that are NOT designed for your phone. That's how bricks happen

You will have to unlock the phone to use in the U.S. Also sometimes stock software is not always compatible in the U.S. You will likely have issues with text and mms messages because of incorrect apns, as well as 4g issues.
