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.

I always thought that Verizon always had bands for international travel also? I mean not really a big deal. Verizon is the clear winner for coverage nationally and since my work is paying for it, its even sweeter.
Right now I just have a blackberry

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.
So I tried searching why the Tegra3 variant doesn't have LTE and the answers are more like "because the lte radio isn't compatible", I'm wondering why exactly is it not compatible?
Same goes for the SIII, it also has a LTE variant(Dual core) and a quad-core chip without LTE.
Its not like I'm suffering from the lack of LTE, its just curiosity.
Anyone ?

qualcomm LTE radio isn't and qualcomm wasn't helpful to Nvidia to integrate it with Tegra
so Nvidia had to make an LTE radio on its own hence the imminent Tegra 3+
Qualcomm wasn't helpful about it to Nvidia? Wow okay. So I assume the current LTE radios are by qualcomm only then.
Found a link explaining the snapdragon(in the lte variant of one x and s3). It includes everything basically, the processor, radio, etc. The Exynos Quad and Tegra3 don't include a LTE radio.
http://www.ibtimes.co.uk/articles/350403/20120609/samsung-galaxy-s3-exynos4-snapdragons4-variant.htm
From what I've read till now, people seem to be more happy with the dual-core S3 than the dual-core one x. Anyways Tegra3+ ought to fix that, its actually gonna be phone raping everything then lol! LTE, higher clocks, less nm manufacturing?
not most likely it will not be an nm shrink
Today, NVIDIA announced that their Icera 410 LTE modem has been approved for use in tablets and clamshell devices on AT&T’s network. While that does not mention smartphone use yet, this is a step towards LTE and Tegra 3 coming to the States in at least some form. As we have documented plenty of times, NVIDIA has been unable to pair its quad-core mobile processor with LTE because its biggest competitor (Qualcomm) is the only guy making LTE modems at this time and likely does not feel like sharing. With today’s approval, this should bring NVIDIA up to speed in no time (assuming they get the smartphone approval too).

I wonder if they'll do something like what Apple does and offer a subsidised trade-in for T3 HOX to T3+ HOX.
I don't think HTC can afford to, however much I would love to be able to
With all this talk on Verizon adding AWS, do our phones have this capability?
If I remember correctly, only the T-Mobile variant of the One has AWS capabilities.
See, here's the thing that threw me off. The S4 variant for Verizon is going to support AWS. Currently online, the S4 and One are both listed as supporting the same frequencies. Is there no chance we could see AWS turned on like the S4 with a future update?
No biggy to me either way, but I figure similar phones with similar chipsets and currently similar cell frequency support, could be possible.
Hey, I *almost* pressed 'buy it now' to pick up an exynos S9+ to use here in the US on Verizon. Then something caught my eye about another listing saying "GSM Only". SO.... I surfed around a bit and found out the obvious: Int'l versions are GSM only, and Verizon's current voice network is CDMA. HOWEVER....I think I've also learned that VZ is phasing out CDMA in favor of using LTE for voice. In fact, they are hoping to have CDMA totally gone by 2019. In another thread on the S8., someone speculates they would have no qualms using a Int'l S8 on verizon since '98%' of their voice network is now LTE.
To complicate matters, this is a work-paid phone plan, so I can't install any custom ROMs- has to be stock.
So- is this doable or should I give up hope? (The reason I'm hot on getting the Exynos model is to use the dual-band GPS when the feature is unlocked, presumably in a future firmware release).
Thanks!
I don't know the time frame but they are certainly moving to GSM. I suspect that a large part is now GSM since they initially started in Canada and Mexico some time ago.

The exynos s9 may work on verizon LTE data, but not on calls. Currently Verizon has CDMA which doesn't work on the exynos s9. If Verizon switches to only LTE then the exynos s9 will most likely have to support Verizon's VoLTE, and VoLTE on the exynos s9 doesn't officially work on stock software with any US Carrier without hacks that would make the phone non-stock. So far the only working modded CSC is on T-Mobile and there is development on an ATT CSC. The snapdragon s9 has significantly better battery life and better performance than the exynos s9. The Dual-band GPS is something that Samsung might not enable. If you aren't going to use custom roms or unlock the bootloader because the snapdragon s9 doesn't have an unlockable bootloader, but the exynos s9 does then the snapdragon will probably work better in the US.
Thanks guys. Looks like I'll be stuck for now in my quest for <10cm GPS
If you have Verizon and you get an Exynos international model in the USA, what would be the practical difference or issues you may experience?
Of course, the reason to get Exynos is for the unlocked bootloader.
Supposedly Exynos won't support any CDMA bands, so you'll only have service under LTE. However, looking at the 4G map for Verizon it's a solid color, so shouldn't this mean you shouldn't really have any loss of reception since you can just stay using LTE always?
How about internet speeds? Would there be any difference?
Are there any other practical differences?
