I'm trying to buy an Android phone that would support AT&T's 3G in North America, but for some reason they all only support T-Mobile's 3G frequencies. What's up?
So pretty much every smartphone nowadays is quad-band, GSM 850/900/1800/1900, and works pretty much anywhere in the world.
Why don't phones also support international 3G frequencies: 850/1900 as well as 900, 1700 and 2100 Mhz?
That should be a rule in all modern devices
100% all communication in all the world!
http://en.wikipedia.org/wiki/Quad-band#3G
if you look at the population in the various places
and add the extra cost it seems to currently offer
feature you request it would most likely
not be worth it for htc and other manufacturers
but maybe in time as first we had dualband phones then triband and now quadband 2g
of cause with 4g starting to take off some places maybe it will be absolute before
universal 3g chips get cheap enough
How do the current business travelers manage?

The area lot of business people who travel all over the world. How do they manage data access? Do they carry more than one phone all the time?
but as I state the only large user groups of 850 3g is in america
like CDMA is also only supported there
it all comes down to if the inc in cost is enough to justify the inc in
revenue
business people from the rest of the world don't have those issues
people here have also been requesting htc phones which does both cmda and gsm
it' all about GREED!
do you know how many channels your radio or TV receives?
those HTC fools just discriminate against USA users! (my opinion)
Q
I would really like to know how much "more" its going to cost to make a quadband, and 5 band UMTS phone. . . . .
think only qualcomm can answer that question

it doesnt matter how much! i'm sure qualcomm 1G snapdragon cpu is more expensive than 528mzh cpu, that doesnt stop toshiba or Acer from using it!
it' all about GREED!
htc wants to make it with the cheapst parts, and sell it at the highest price possible! (my opinion)
well yes
even if greed is a negative word for the general capitalism which drive all these company's
it's not like htc are the only ones on that ship :S
Quad band UMTS are rare indeed. Blackberry and Apple have them. Nokia has a quint band unit coming out in about 3 weeks, N8-00 (I have one on pre-order).
The Galaxy S Captivate is a tri band unit that will work in most of the world. It is missing the 900 MHz band. I can't recommend it because GPS is broken while awaiting a software patch and AT&T refuses to unlock the sim for 10 months. There is no known way to unlock the phone at the present time.

Don't be so hard on the manufacturers (please, note that HTC isn't the only phone manufacturer in the world...) AT&T only just started selling Android phones. Why would Android phone manufacturers make a phone that supports AT&T bands if AT&T won't support them in return? With the delays in so many phone shipments, I'm sure the companies don't need that much more business than they already have. Now that AT&T has decided to play ball, however, I'm sure there'll be a reciprocal increase in the number of Android phones with AT&T 3G bands

You can buy an unlock code for like $25 .
I have the option of either picking the LG Optimus 7Q - C900 or HTC 7 Trophy. I have looked at both phones, played with both phones and still unsure.
From what I can see these phones are on slightly different networks but not enough for me to be concerned as most of the time I'll be on wifi data (I'll write the specs of phones and network at the end)
The LG has a Keyboard, great if I want the full screen when typing but on the flip side not all applications go to landscape.
The LG feels a more soild phone but with this comes weight.
It seems to have more radio bands, but so what if your country only has 2 main telcos.
I haven't read bad posts (apart bad design keyboard) about this phone.
now for the Trophy
Better user support like a decent group in xda.
Only has a 8gb built in SDcard
Seems to have better Sound options/mixing when listerning to music
Better custom applications
Lighter than the LG
Supplied by the network we will be using
I am concerned about all the issues in posts I have seen, is the phone really that bad?
So can anyone help me out, have you tried both and perfered one over the other, why?
Networks.
In NZ we have 2 main telcos with a couple of smaller company's using their tranmitters. The contract will be with 2degress using Vodafones equipment.
from what I can see here is the specs of both phones
LG
GSM 850; GSM 900; GSM 1800; GSM 1900; Edge; HSDPA 7.2; HSUPA 5.6; UMTS 850; UMTS 1900; UMTS 2100
Trophy
GSM 850; GSM 900; GSM 1800; GSM 1900; WCDMA; HSDPA 7.2; HSDPA 900; HSDPA 2100
It is hard to find true network information about Vodafone in NZ but from what I can tell they use 3G 900 and 2100 for their broadband so I don't see a magor issue here, can anyone else?
Cheers
First off, there is a separate forum for LG Quantum. Secondly, I wouldn't recommend Trophy even to my enemy. It is far slower than my Optimus 7 (at least a 2-3 second lag on loading apps, mostly games), but the screen looks to have more contrast.
I can attest to the fact that both Optimus 7 and Quantum are QUAD BAND GSM AND QUAD BAND 3G, so no worries on the network front of things.
Just get the LG.
Me Too..
I am going for an handset upgrade and I have 2 options, Lg or Htc 7 Mozart. Dunno which one to get. Too confused!
Lg has better space capabilities than htc
Htc has better design than Lg
Dunno which one to choose!!!
Please help!!!
Honestly, the LG design is better than the HTC...seriously, the HTC crop of phones with WP7 on them are a failure this time around...Do not go with the fact that HTC has a good reputation or hardware. This time around LG and Samsung nailed it. The LG Optimus 7 I have now is far more solid and has a better feel hardware-wise than the two HTCs (TP2 and NexusONE) I have had in the past two years.
I advice you to go for the LG, I have one and looks really solid, I bought it although I am not a fan of LG phones but this time it seems that they succeded)))
I just got the optimus yesterday and I am very impressed with this phone. I cant believe it hasn't sold more then this. The build is great, really solid, Windows 7 is awesome and clean. I prefer this much more to Android. LG did a really great job with this phone. I have avoided LG like the plague but am very please with this device. Only thing I would have like is a better screen but its not that big a deal.
dont forget abput the LG apps that they are givingaway some of them are very very decent LGs own apps and some of the others are also good, iv got the optimus 7
cant realy comment on the HTC
i know this makes no diference if ya develop ya phone but not evry one will do this
so free aand installed apps could be a deciding factor
Hi all,
Im thinking of buying this phone but from what i have read there isnt much difference between the Atrix and the Atrix 4g.
How will I be able to tell which is which? specs are almost the same.
Should add that I am buying used. Also, I am in the UK.
Look forward to your replies!
They are the same phone!
I'm also in the UK, really like my atrix, but coming from a modded android to a locked phone is a bit difficult...

your sure? i read somewhere that the first atrix has 5mp cam which has been upped to 8mp in the new version.
Maybe im mistaken.
Yes ive heard about Moto not playing nice with rooting!
It is the Atrix 4g and the Atrix 2. And the Atrix 4g has a 5 MP camera and the Atrix 2 has a 8 MP camera. The most noticeable thing I saw in the looks of the 2 phones was the Atrix 4g has the speaker on the back at the bottom and the Atrix 2 has the speaker on the front at the top.

yeah that's right... looking at the specs on motorola website, seems that's the only difference!
cool, now i know what to look out for!!!
atrix(4g) is not a locked phone, is it? If you follow the guide, you can unlock the bootloader and flash different ROMs on it.
Another difference between atrix(4g) and atrix 2 is the fingerprint scanner. atrix 2 doesn't have it.
Since you are in the UK you will probably want the "Motorola Atrix" since it has the 900MHz UMTS band needed for some UK carriers like Vodafone and O2.
The "Motorola Atrix 4G" is the title used for the Atrix line that is used in North America for carriers like AT&T and Bell.
Look at these two links and you will see that the main difference is the bands used for their 3G networks. AT&T and Bell use 850/1900 and Vodafone and O2 use 900/2100.
http://www.gsmarena.com/motorola_atrix-3709.php
http://www.gsmarena.com/motorola_atrix_4g-3708.php
I could be wrong but this is what I can gather from your question. Also, you might be able to use the "4G" branded one because it still uses the 2100MHz band (if unlocked) but you might experience reduced coverage (slower speeds).
The difference in cameras is between the Atrix(4G) and Atrix 2.
http://www.gsmarena.com/motorola_atrix_2-4199.php
Which also does not use the 900MHz band.
EDIT: I would also like to point out that they do all use the same "Quad-band GSM" but that is for the 2G(EDGE) network, and not 3G(UMTS/HSPA)

Some suggested the only difference between atrix and atrix 4g is the firmware. But I don't know how true it is.
I have a Bell (canadian) atrix 4G, and I am currently in UK on O2. Is there any way to tell if I can use UMTS900 or not?
If there is a way to tell, and I manage to connect to UMTS900, then I will say there is no difference between atrix and atrix4G.
Right, an unlocked Bell/AT&T Atrix will work on almost all of the UK networks but it will be restricted to the 2100MHz band for 3G(HSPA) or quad-band GSM for 2G(EDGE).
You don't need to try "to tell" if your Bell Atrix is using the 900MHz band for 3G(UMTS/HSPA) because it cannot. It's in the specs, it just doesn't have the capability.
http://www.bell.ca/Mobility/Products/Motorola_Atrix_4G/Specifications.tab
Just to clarify, I'm not saying you can't use an unlocked AT&T/Bell Atrix in the UK, all I'm saying is it will not be able to use the 900MHz band for 3G. It will, however, be able to use it on EDGE/2G. I'm fairly certain it's a hardware thing.

People seems to be either pretty certain it is only a firmware difference, or pretty certain it is a hardware difference. But no one can confirm which one is correct...
I do agree, based on the spec from motorola, US/CA atrix doesn't support UMTS900.

Same result I've had. I've posted a question thread on the modems here.
http://forum.xda-developers.com/showthread.php?t=1442350
Its annoying me because if its just a software limitation, what is there to stop us from giving it 900mhz umts support? The "workaround" just needs discovering by a developer (I've been mooching around, but i'm not dev!)
O2 UK has UMTS on 900MHz now, and one local to me so I want to use it without replacing it for a UK atrix lol.
What we need is an international/uk user to be brave and strip their phone down and find out for us!
My gut feeling is its something in the kernel/drivers/boot loader provided for the AT&T Atrix. On samsungs there is a secret menu for turning bands on and off.. but none of those codes will work on the Atrix of course (even the generic test ones built into android don't work!)
If you know anywhere close to London where o2 has UMTS900 coverage, but no UMTS2100 coverage, then I will try it out.
If I can get 3G at that location, then my Bell Atrix with UK baseband works with UMTS900. If not, then it is more than likely to be hardware.

If you can come down to Solent Business Park/Whiteley you'll have it there on 900mhz. They were digging up the road a few weeks ago right by the mast (which is pretty much line of sight with my office), and I took my Nokia N900 (on GiffGaff as its a spare!) which supports UMTS 900 and it had full 3G signal (atrix had full 2g), which it could never get before. The nearest 2100mhz mast is like 2 miles away. The atrix will pick the 2100 mast up rarely down there, and when it does, it has 1 bar if that.
I tried a few different base bands while at work, none seem to provide positive results on my AT&T Atrix.
When it comes to the differences of the Atrix and the Atrix 4G, it is the 900MHz UMTS band. The Intl version has it but the AT&T/Bell version does not.
While the OP (@jman316) was looking for the differences between these two versions, you seem to be trying to figure out how to access that band on the AT&T version, which is not possible.
GSM and UMTS are not compatible. UMTS is an evolution of GSM but they are not the same. So, going back to your dilemma, you have stated in your other thread that you currently have an AT&T version. Based on that, you cannot use the 900MHz band on 3G/UMTS/HSPA. Only 2G/GSM/EDGE.

http://wiki.answers.com/Q/What_is_the_difference_between_umts_and_gsm
To reiterate, quad-band GSM is not the same thing as UMTS/HSPA The AT&T Atrix can only use the 900MHz band on EDGE/2G, not 3G/UMTS/HSPA.
I apologize if I seem derisive on the matter, I just feel that the facts are right there.

I'm very aware of the differences in the technology. I don't know where your comparison of GSM/UMTS and the links relevant here. Its a quad band gsm and quad band UTMS/WCDMA/3G phone with one band disabled be it through a hardware modification to the chip or by software.
What we are trying to drill down to is this:
1. Is it the same cellular modem chip used in both AT&T/Bell and the international versions?
If yes then,
2. Why is it not possible to enable the disabled band?
Has anyone really done any research into either of these? No. If had a spare pool of money I'd buy a UK phone, and strip it down, and prove once and for all what difference there is, and we could then say, oh so the chips are different models so that explains that or go, oh its the same chip/part number, lets hack the software a bit.
Also Atrix 2 uses normal tft lcd instead of pentile as in original atrix.

We are not on about the Atrix 2, we are on about Atrix 4G (US) vs Atrix (UK/EU/World)
What I have quoted above about 3G on 900mhz should be possible, here is a little pointer (evidence perhaps?) as to why it should work...

http://www.scribd.com/doc/54154049/...odem-Device-Specification-Advance-Information
I have done a lot of research into the matter and from what I have gathered the chips/modules responsible for the compatible frequencies can be tailored to specs according to the customer's (AT&T) requests. Which, from my understanding, would be a hardware issue. So, even if they have the same chip, it wouldn't matter, since AT&T can have it custom made to just use the frequencies they approve. Which actually sounds a lot like something AT&T would do, given their track record.
I also found this thread where others are pretty certain it is not possible:

Hi everyone. I'm buying a used, unlocked T-Mobile DVP 8GB soon, manufactured around January 2011 and is supposedly running Mango. I realize the phone is filled with issues, but they have supposedly been fixed by now. I'm just wondering if there are any specific issues I should check for before going ahead with the sale. Thanks!
No compass...yet
That's fine with me. I was thinking more along the line of things like checking all the keys to make sure they type the right letter (saw in another thread that x and z were switched for some reason), the device can be detected by a computer when connecting through USB, the phone doesn't reboot when you touch the screen, etc...
Also, what's the latest firmware/OS version for the DVP right now?

I've had absolutely no problems out of my DVP. 7.10.7720.68 is the latest OS version on mine. Yeah, the compass is a strange omission considering the hardware is there and was originally implemented but maps seems to orient just fine when I need directions. GPS is crazy fast.
Sounds good! Do you know the latest firmware version number as well?

latest DVP update is 7.10.8107 if the mobile is a factory unlocked version
if you have operator specific model like say T-Mobile / ATT then it would be 7.10.7720 or in some cases 7.10.7740
I too am considering a Dell Venue Pro. I am on Mobilicity in Toronto area and getting a decent Windows Phone that operates on AWS frequencies (1700/2100) is a challenge. T-Mobile phones are the only option but ordering a T-Mobile phone into Canada is a challenge too. It would be simply easier to drive to the NY State or Michigan and buy from a T-Mobile store and then unlock but I don't have 3-4 hours to burn. The Dell Venue Pro is easily available and is unlocked even ordering from Amazon.com.
If anyone has serious reservations please advise. Even better if someone is reading this and is on Mobilicity with this phone, I would appreciate any comments good or bad.
DVP !!
Hey,
M in India, and I got a DVP unlocked 16 gig, and I have no issues with it.
For me its the best looking phone out there
I dont care much about the specs(I mean if you compare the phones out there today, DVP lags behind), and the specs that a DVP has, is enough for me.
I have had only one stuck up, where I had to remove the battery to power it back on. That's it. Otherwise it has worked smoothly.
No other random reboot, no lag.
One thing, the camera is bad. You wont be able to take motion pictures. It will be blurry.
After Mango update, and making some changes in the settings, the still pics are gr8, but if you are trying to capture something that's moving, then m sorry, this aint the phone for you
I bought it in November 2011.
Current version:
OS version: 7.10.8107.79
My verdict: If you like classy, go for the DVP !!!
Excuse me for any typos or wrong grammar, English ain't my first language.
I picked it up yesterday, and so far I love it! There are a few things tripping me up, but nothing that i feel would push me over the age to abandon the platform like I did with Android. For one, it would be nice to be able to push enter to send an SMS using the keyboard, rather than having to touch the send icon on the screen. It would also be nice to be able to block certain numbers from calling.
Battery life does seem like an improvement over my old phone, though.
If you are purchasing new, in the US, I would question it. The phone is old hardware, at least 18 months old, I'd not more. Does not do 4g or wifi n. Simply put, why would you invest in an old device.
If you are buying used, or cheap with no contract, its worth it. But, buyer beware. A lot of used phones are showing up in a less than ideal condition, with damaged SD slots, or with the ability to reset missing. In these conditions they are virtually impossible to fix. Just be careful
That being said, these are good devices, well made and sound. I do not regret purchasing mine way back when. It was a most amazing Christmas present when received on December 21st, 2010.
Just to let you know I opted for a Nokia Lumia 710 !
Great deal here in Canada for 254.99 (from Rogers no contract) then $10 for unlock code. I know it's a completely different phone from DVP but figured I may as well get on with latest model phone for fairly cheap price. It will give me an idea if next (more expensive phone) should be the Nokia 900.
Thanks everyone for the mainly good comments about DVP.
We've discussed it for a bit here
Though if you're on rogers you actually have the choice of any of the lumias. (as rogers uses the same 3g bands as at&t and regardless prob has more choices)
TmoUSA users dont though, it's either the 710 or the VP or radar. (there's very little selection for AWS devices, that's almost literally every AWS capable wp7 device)
Yes... actually I am on Mobilicity which is same band as T-Mobile (1700/2100).
The Rogers Lumia 710 is a penta band phone so yes it works with Rogers 3 G bands and AT&T bands, and of course it works perfectly with Mobilicity ! (had to unlock it though)
Wonder if the T-Mobile version is penta band ? Also wonder why Rogers doesn't advertise this? I did some reading and found out it's penta band but if you read the specs from Rogers website it's only showing as quad-band. Quick trip to a Rogers store and reading the label shows it's penta band.
http://www.gsmarena.com/nokia_lumia_710-4276.php
Perhaps they dont want you purchasing one and turning it to another carrier?
For a carrier sold one the supported bands arnt really relevent, as long as it supports their own band obviously.

I doubt this, because I am not sure that the Qualcomm chipset actually supports pentaband UMTS.
It's more likely that it's quadband UMTS, which would still allow it cover all UMTS frequencies for both ATT and T-Mo. As in, maybe they left out 850 or 900.
Reports are the rogers one works on wind, which is AWS like tmoUSA
That would mean it's at very least: 850/1700/1900/2100, with the question as to if it supports 900.
As: 850/1900 is what rogers uses (like at&t)
and: 1700/2100 for aws (it's more work to have a 1700 device without 2100 then to leave it in)
From my understanding, it's merely what amps the manu decides to put in, and what they decide is mostly politics.
All htc devices are dual band unless they're forced to add more
Most samsung international devices are triband or higher. (though they dont generally use qualcomm chips)
All dell devices are triband or higher (with the exception of the EU Streak 5 as the AWS is uncommon)
I cant actually confirm it as I dont actually recall seeing a 5+ band phone using a qualcomm chip.
Worst case you can do APQxxxx + MDMxxxx and use an external modem that does support it, i believe the MDM9200 explicitly supports 5 bands + lte bands.
All devices with APQ8060 chips do this, as APQ chips are by definition chips without modems. There's a few phones that use this setup.
tl;dr the rogers varient should support at least 850/1700/1900/2100, since at least on at&t they use both 850 and 1900 (not unreasonable to assume rogers does the same)

Reports are the rogers one works on wind, which is AWS like tmoUSA
That would mean it's at very least: 850/1700/1900/2100, with the question as to if it supports 900.
As: 850/1900 is what rogers uses (like at&t)

Can confirm the ATT version works on Rogers bands. Sold my unlocked DVP (ATT) to a rogers users. He reported it worked fine on 3G.
I have to buy a smartphone, most likely Android, that will run on the CellularOne network. I'm familiar with both ATT and Verizon and I do a lot of work with Android on the Verizon network, but I'm clueless about the CellularOne network, and I realize that some phones that will work unlocked still wont connect to 3G.
Can anyone give me some information on smartphone models that will work on CellularOne with 3G mobile network connectivity once I unlock the phone and change the APN settings.
Or if there's some specific specs I can watch for as a guideline to know which phones will work on the cellular one network.
I've heard the HTC Amaze 4G will work when unlocked with full 3G connectivity and that's a phone we are considering, although it's a little expensive for the person I'm buying the phone for. Any info you can shed on the subject will be appreciated.
While I feel sure this topic has been discussed, I've been searching this morning and couldn't find very much information on the subject.
I'm not sure which bands Cellular One uses, but I know that most T-Mobile phones support 850, 1700/2100, 1900, 2100 MHz. I believe those are the only HSPA+ 3G/4G bands used in the US. You can't go wrong getting the Amaze and unlocking it.
I've tried quite a few T-Mobile phones, and the top three in my opinion are: the Galaxy Nexus, HTC One S, and Galaxy S II. The Amaze 4G is nice, but battery life is pretty sub par.
You should be able to find all three for around $300 on craigslist.
