I've been searching 850 and 2100 3g supported smartphone.
Since I use at&t in the US but internationally travels, I think this is the best combination for me but those are not many.
I've only found Nexus One with at&t model which thought to be as fiasco and also HD2 T9193... Anyway those phones are old..
What else phones are available? Your help is much appreciated.

HELP!
I am at my wits end trying to find a US 3G compatible HTC device. I really like the Blackstone, but it seems that it won't do 850/1900 HSDPA frequencies. Does anyone know which HTC devices are compatible with AT&T networks?
I even wrote HTC about the Blackstone. They told me it is compatible on the 850 band, but that's not what the specifications say. I'm so confused. I am an electrical engineer and understand all the technologies, I just don't know which devices are "world" devices. Does anyone out there know?
Am I sentenced to the world of edge with HTC devices because of AT&T network frequencies?
The Touch HD is really cool phone and would love to have it if it does 3G on AT&T.
Thanks,
The Kaiser was one of HTC's last phones to have good tri-band UTMS support; ever since then, it's taken the strategy of releasing N. American and international versions of its phones that have different 3G radios (850/1900 and 900/2100 respectively, but you know that already. ). Once exception is the Fuze, since AT&T wanted it to have 3G roaming, so it has the 2100 band as well as the American ones.
You can find a N. American version of most HTC phones besides the Blackstone, unfortunately. I don't know why, HTC just made a decision that it wouldn't be released over here. Might be because they don't want it to compete with the upcoming Touch Diamond 2, which has a similar set of features.
this new Telstra HD works for usa 3G 850...see this thread: http://forum.xda-developers.com/showthread.php?t=487010&highlight=telstra
I saw this phone on the database site. I hope this is the right place to ask this question. I was wondering if this phone could be used on AT&T network? I know the phone isn't out yet, but I wanted to know. Because I love the style of the phone. I have the 2 before it.
Thank you for any help.
The European HTC 7 Pro will work on AT&T's Edge Network, but not the 3G. European 3G is in the 900 and 2100 MHz bands, AT&T 3G is the 850 and 1900 MHz bands. I would imagine you'd get 3G service on an European 7 Pro with T-Mobile, but not AT&T. If you're willing to give up the 3G go for it, it looks like a great phone, and a perfect successor to the "Tilt" line (AHEM AT&T!!!).
I just did a search, and turned up these results, for those that might be interested:

[Q] Help with AT&T bands, or why the rest of the world is more advanced than the U.S.
I need to buy a smartphone before the end of June for use in my new life in mainland China, but have ended up with many questions regarding how useful my phone would be if I returned to the U.S.
So China, being civilized like the rest of the world, uses only the 2100 band GSM for its 3G, at least at China Unicom. So as far as I understand, any phone that gets GSM 2100 gets 3G.
The trouble is what happens if I move back to the U.S.? I want a phone that will last for years. Seems like the only game in town is AT&T unless the feds stop the T-Mobile deal. So my phone has to be 850/1900/2100 to get 3G in the U.S., as I understand it. (At&T isn't exactly forthcoming on this on its site, so this is from this forum and other sources.)
My two candidates are the LG Optimus 2X and the Samsung Nexus S. The 2X has 900/1900/2100 3G bands and decent enough hardware that I'm relatively futureproof gear-wise. The Nexus S has -- at least where I live currently -- 900, 1700 and 2100 3G bands, and Google's stamp of approval means I'm futureproof on the software side.
My confusion comes from what all these numbers mean. Does my phone has to be just one of these bands to get 3G? Two of them? Or is all this a misnomer, and 1900/2100 is in fact its own unique band? Why do I need all these extra bands when most countries have just 2100? What am I missing if I go LG 2X and miss the 850 band?
Does having only two and not all three on my phone mean I would get 3G data only some of the time? Or must I meet all these criteria? Is one upload and one download?
And why is U.S. telecom so screwed up while the rest of the world seems to do just fine? (OK that one may be more of a rant than a question)
There are phones that hit on all the bands, but Motorola is closed software-wise and I don't want that, while Samsung Galaxy S II and iPhone 4 are both too expensive for me.
I'm clearly slow, and not an expert, but if anyone has time to educate me I would much appreciate it.
Hmm, this site suggests AT&T works on either 850 OR 1900. In other words, you need just one or the other on your phone, but not both:
wwwSPACE.cellularmaps.com/att_850_1900.shtml ((sorry I still can't link))
So the LG Optimus 2X would work in U.S.? Pity about Nexus S, because I prefer it for the likely long-term developer support, but life wouldn't be so bad with the Optimus 2X, now would it?
So I have no idea whether this is true, but Google and message boards tell me AT&T has two 3G bands, one 850 and one 1900. They don't need each other to work. Instead, they just duplicate.
Why? I don't know. There may be no logical reason, this being AT&T.
So that suggests in places where AT&T has kept 1900, a phone like the LG Optimus 2X (900/1900/2100) will work fine, and in places where it doesn't it won't. This map suggests wide overlap.
(Still can't post links. Great. Google "cellular maps" "AT&T" "850" and "1900." Thank God the board is safe from links!)
Bear in mind that none of what I've written here fits the definition of "fact." I have no education in this. But somebody's gotta continue the conversation and I'm unafraid to look stupid.

The bands are frequency ranges, so it means that the phone will broadcast/receive on the 850 MHZ range, or 1900 MHZ range. Don't know if this helps, but that is what they are talking about.
Check out PDADB
I think you will find www.pdadb.net to be your new friend. So bottom line is if you want AT&T 3G you need 850/1900, Australia and Canada are the only other places that utilize these bands for their 3G from my knowledge. If you can find a Nexus S that has the North American bands it will do AT&T 3G (it will be the Canadian version). The normal Nexus S state-side is the AWS packed version (AWS = 1700 or T-Mobile 3/4G).
900/2100 are your standard European international 3G spectrum, and well 2100 is pretty much everywhere, even China as you found!
Say you go the AT&T store and ask them for a "World" phone then it is more than likely banded for 2100 in addition to 850/1900!
I hope that helps you!
EDIT: On PDADB.net you will want to look for UMTS850, UMTS1900, UMTS2100. IF it says GSM850, 1900, etc. that means it will do 2G on those bands but not pick up 3G on them!
EDIT 2: Nexus S with AT&T bands can be found here just click on Source 1 at the bottom of the article!
Thanks all! Yes, big help.
Where I live the i9020a hasn't appeared, and why should it? It's needed only in America. Meanwhile, the LG Optimus 2X is the same price here as the Nexus S, which is very very tempting.
Still, I may hold out until the i9020a or the white version of the Nexus S appears, and decide accordingly.
Dear all,
I d like to buy a phone that has 3G in USA with Tmobile (on the 1700 Mhz freq) and 3G 900Mhz in Italy. I am italian now in USA for a 1 year job and I bought a phone that only has 1900/2100 so I have trouble with the 3G on Tmobile, it only gets the signal sometimes in some refarmed areas, overall it sucks here in PA. What is the best pentaband phone you would suggest? I was looking for Nexus IV, but it does not have the the sdcard. What about the Samsung SIII? I did a search online but it looks that the tmobile version misses the 900 frequency and the international version misses the 1700, so there is not such a pentaband Samsung SIII? Any pentaband alternative to the Nexus III that has the SDcard?
thanks
A.
go for the nexus 4, you will not miss the external sdcard,

LOL I'm an idiot, was thinking HTC ONE when I said one hd...
Found a really good deal ($170) on a bnib razr hd from verizon with a bad esn on ebay. Didnt really have the time to fully research it before the auction ended so I just took the chance and placed the order.
Did some searching after the fact and have found some really conflicting information. I know the phone would be pretty much useless in the states, but I'm unsure of its usability in Canada? I've herd they would work fine in asia and india so I'm basically curious if anyone knows the extent of how far verizon shares its blocked phone information? Does it extend to Canada?
I've herd on the states you need to have your phone activated onto a network? In Canada we just throw in our sim card and are good to go. Is this a different technology (CDMA vs GSM?). If so assuming the Activation portion of the phone is blocked could the sim card part of it still be open theoretically?
Assuming its possible to work with the bad esn does anyone know if I could use LTE on Bell/virgin?
According to bell it uses LTE AWS 1700mhz and LTE 700mhz and HSPA 850mhz and 1900mhz
According to gsm arena the xt926 uses:
HSDPA 850 / 900 / 1900 / 2100
4G Network LTE 700 MHz Class 13
Should be fully compatible no? I cant find any information on what class bell uses for their LTE, nor do I know if the class affects anything?

You can unlock it for gsm carriers in the us and its already unlocked for international use. I know with att u get h+ witch is good enough for me on straight talk. I average about 6mps.
Got the phone on the weekend. It works fine on bell/ virgin except I can't connect to lte. Does anyone know of it's possible to unlock lte? According to gsm area the phone should be compatible with lte 700mhz which is what bell uses... Will that radio com thing you guys use to unlock it for us carriers help?
