Quick question, im looking into buying a cheap chinese phone because 1, im not picky about being top of the line, and 2, because its inexpensive. But ive been looking into and around the internet for supporting information stating if these chinese phones work on Tmobil, AT&T, Net 10 or Striaght talk. Here is the general break down fo these phones
Operation System: Android 4.0
·4.3 inch Capacitive Multi-touch screen, QHD (540*960)
·CPU:MTK6575 CPU 1GHZ Dual core
·Quadband: GSM 850/900/1800/1900MHz 3G WCDMA 900/2100MHz
Id like to know if this type phone would work with the above companies with both talk/txt/mms but also with 3g full US coverage. Thanks in advance
-Nick
Compare the GSM and 3G bands with a well known model at USA
But I cant get a straight answer out of anybody...
I know that the talking/txting/mms will work on the GSM bands provided but its the 3g that im thinking about
I see different things all over the place; some phones are 800/2100, 850/2100, 900/2100, and 1700/2100. The 2100 is prob the only consistent band, but i dont know if, say, 900 correlates to western US and 2100 correlates to eastern half. OR the 900 and 2100 cover ALL of US and you need just one of them. Besides that, several phones on I think tmobile such as the HD7, here's a link to what I mean,
http://www.gsmnation.com/htc-hd7-tmo.html
The top says 1700/2100 but the description states 900/2100 for 3g?!?
Heres a link to one of the phones I was talking about that I was looking into
http://www.fastcardtech.com/goods-7...ouch+Screen+WIFI+G-sensor+3G+smart+phone.html
Thanks,
Rico
Any thoughts on if this phone covers AT&T or Tmobile? Id appreciate any help, thanks guys
Rico
For AT&T, the band is 850/1900 MHz for both GSM and WCDMA 3G. For T-Mobile 850/1900 MHz GSM and 1700 MHz for WCDMA 3G. If your phone is WCDMA 900/2100, 3G will not work for both AT&T and T-mobile. You must have at least one band that matches with your network. For best 3G coverage, both bands must be supported by the phone.
Have a look at this phone with WCDMA 2100MHz (800/850/1900 optional) here: www.chinaphonereview.com/samhave-aone-shanghe-a1
Also look at these phones that have 850/2100 WCDMA bands: www.chinaphonereview.com/zopo-zp100 and www.chinaphonereview.com/zopo-zp200.
Cool, thanks for the link man, I like the ShangHe Aone 3G Android 4.0 you recommended. Do you know of any others? Im just looking for android 4.0 and a nice (not super nice) 4.3'' screen. I was also looking into an Ezio H7 but its android 2.3 and im not sure of the screen quality. Any thoughts? thanks in advance.
I also found these phones with 850/2100 MHz WCDMA bands: Star Xperia S LT26 and THL V9.
The THL V9 has a 4.3 inch screen with qHD resolution (960 x 540 pixels) and Android 2.3 but I think it has already an Android 4.0 update. You might want to check it out.
I was looking into those as well as IHTC 310x or something like that, but the 3g bands are 850/2100 but i need 850/1900. Any other phone references you know of?
Thanks y'all
nick
Hell, ill take a phone with 1700/2100 bands too... if they exist... which i doubt in china.
Most Chinese phones I know are 850/2100 or 900/2100. The ShangHe Aone may be the only dual SIM phone with optional 850/900/1900 bands.
The Meizu MX has a WCDMA/HSDPA band of 850/900/1700/1900/2100 MHz. This phone is high-end, with dual core 1.4 GHz CPU. It also has a quad core version named Meizu MX Quad-Core. Both are very affordable for their specs.
Anyone make any progress in getting this figured out? I've been looking into buying a chinese phone to use on t mobile and it looks like most of them operate WCDMA for 3G speeds, which won't work on t-mobile. Does anyone actually have one now that they're using?

you need one with both 1700 and 2100 in order to get 3g hspa unless your in a coverage area where tmo already supports 1900. in some areas where im at people i know with crapple iphones get 3g where tmo has refarmed thier netwok they are working on getting this frequency to more areas so its wait and see

Simple answer....NO
I too was looking to buy a chinese phone with hope that I would be able to get 3G on Tmobile. Tmobile's 3G unfortunately runs on the 1700 MHz band. If you don't see that band in the phones description you will only get 2G aka EDGE network on TMobile.
So this phone wouldn't work with Tmobile?

I don't know for America, and I am not a techie myself, but from what I understand, you have to look at the frequencies the phone proposes.
In Belgium, 3G works on 900 / 2100 MHz, if the phone doesn't support this, you will fall back to 2G.

In addition to 1700 MHz, T-Mobile also supports 2100 MHz so 3G will work where you get 2100 coverage in USA.

This is not entirely correct. Part of T-Mobile's HSPA network operates on the hybrid AWS 1700/2100 Mhz frequency where one part is uplink and one downlink, which is not the same as operating solely on 2100 Mhz frequency like many of the Chinese phones work with and many other countries use. They are not compatible.
However, that being said, their HSPA network also works on the 1900 Mhz frequency in most major metro areas of the US now as well as many other parts and many of the world phones do support that.

Hey,
The T9193 version of the HD2 has the radio bands 850/2100 in it for HSDPA 3G speeds, but just the 850 band is needed to support AT&T's 3G service in the US.
Would it be possible to create a new radio ROM that disables/turns-off the 2100 band for U.S. users, since this band is useless anyway, and it may help extend the battery life of our HD2 by not having to power the 2100 section of the radio, especially if it makes any transmit attempts by the phone on the 2100 band (transmitting uses a lot more power then receiving).
Any chance of this?

T-mobile is also using HSPDA/3G @ 850 also and nowhere else? I hope so because pretty much half or better of the users of these forums are T-Mobile and *not* AT&T subscribers. Jus sayin.

ROM cooks do not have such fine grain control over radio bands.... Sorry.
I don't believe the T9193's radio has the 2100 Mhz band, otherwize I'd be able to use it in my area to get 3G coverage. (We only have Edge on the 850 Mhz band here)
Hopefully someone who knows for sure can answer this.

I'm pretty sure the T9193 has the 2100 band, but 2100 is useless in the US because AT&T uses 850/1900 for 3G. The T9193 is an Australian phone made for Telstar (their cell phone company). The 3G bands used over there are 850/2100. So, because AT&T also uses the 850 band, thats why we are able to use this phone with AT&T's 3G here over in the US.
However, the 2100 band of the phone is useless in the US because is was intended to be used for 3G in australia.
The good news is that AT&T is phasing out the 1900 band for 3G and switching everything over to 850, so the HD2 will just get more and more 3G coverage as time goes on and then even the 1900 band won't be used anymore so it would be irrelevant if the HD2 has a 1900 band or a 2100 band because both would be useless.

Well, you neglected to say where "here" is
The best available combination for world-wide 3G access is 850/2100 Mhz. This is because:
1) 850Mhz is used in Canada, US, S Americas, Aus, S Africa for 3G broadcasting in regional areas (and in some city areas)
2) 2100Mhz is used in Asia, EU, Aus cities for 3G broadcasting
This is due to the actual physics of velocity = frequency x wavelength
Some telcos use 1900Mhz in the cities, but also broadcast in 850Mhz
Other telcos use 900Mhz in the regional areas, but also broadcast in 2100Mhz in the cities
ATT in the US uses 850mhz in the regionals and 1900Mhz in the cities. This ensures that "their" PDA's cannot use other SIM's - I have no idea why the dumbed-down US market meekly accepts that
The perfect combo is tri-frequency hardware, such as PDA manufacturers used to provide but do not any more (no excuses, it's just straight cost-cutting and sleight-of-hand marketing BS to suit the greedy telcos)
The HD2 released in Aus through Telstra is hardware-filtered for 2100/850 Mhz, the best available combo for world-wide use (not perfect, of course)
The HD2 released in EU/Asia is 2100/900 Mhz. This will access 3G in most cities world-wide (note that China uses 2100/850) but has limited coverage in regional areas - yes, I know there many 900 Mhz deployments but these are very limited geographically
The HD2 released in the US is 1900/850 Mhz. This is very limited for world-wide cities and excludes 3G coverage for those countries that use 2100/900 Mhz
None of this has any relation to GSM coverage, so please do not confuse them
Is the hardware actually different?
I live in NZ and unfortunately bought a T-Mobile unit which is set up for 1700/2100mHz which means that when in the cities I get full broadband, but in the regions I only get dial up speeds through GSM.
My question is does anyone know if the hardware could actually use the 900mhz broadband - or is it a pipe dream on my part that hopefully someone will release a ROM to access some previously hidden hardware?
I do recall with my Touch that there was a GPS built into the hardware that no-one was aware of for a year or two!

However, with our experience in the industry we have seen that almost every device launched in recent years within Europe has been ‘optimised’, with the American 850/1900 range locked down, leaving only 900/2100 for the rest of the world. As we are based in the UK it is for this reason we have taken the tentative step of advertising only these frequencies.

http://www.mydaily-gadget.com/news/5718-att-getting-samsung-galaxy-s2-gt-i9100-fcc-says-i-do
Speaking about release dates we do not have a specific one for the GT-i9100 in the USA but we can confirm the FFC has authorized the use of this particular smart phone on the 850MHz and 1900MHz GSM frequencies which means the first carrier to offer the Samsung Galaxy S II might be AT&T. These two frequencies account for the AT&T 3G network but they also match some Canada operator’s frequencies so there is a big chance the Galaxy S II will land there too in the near future.

That first link (that I provided earlier tonight I think) - read it to the end please, Clove has all the info on that page, just finish reading it. sorry for the tone , but I think you did not pay enough attention - there are comments to that blog post that say clove confirmed with the manufacturer and local distributor that all 4 bands are present.
I'm confused here
I have SGSII ordered from Clove. I plan to use it with ATT sim card. Have I made a mistake? Will I be able to use it? Do I need to cancel?
I hope it works well with AT&T since I intend to get this phone.
My current (imported) GT-i9000 did not properly support AT&T and has very poor call quality and call drop issues.
Sent from my Xoom using XDA Premium App
Although Clove originally said they doubted it would support 850/1900 3G+, they did later confirm their stock would be quad-band 3G. So no need to worry about support for NAM 3G.
Once someone get's the GS2 in USA on ATT, can you confirm that it indeed works on Edge AND 3G?

That's because the i9000 is only tri-band UMTS and only supports AT&T's 1900 frequency. When it gets to an area where the 1900 H/3G signal is weak, it can't switch over to the 850 UMTS simply because its hardware doesn't support it. So, then the phone call drops. You'll notice if you switch the i9000 to 2G/Edge, you'll never get a dropped call... because it's quad band GSM.
Also, ever notice you never get dropped calls when stationary and on H/3G? That's because with a solid 1900 UMTS signal, the i9000 will never search for the unsupported 850 band.
(And yes, I have confirmed all of this as I also own an i9000.)
i9100 supports quad-band UMTS with 850/1900 H/3G, so you will not have the frequent dropped calls anymore.
Here are the frequencies for AT&T: http://en.wikipedia.org/wiki/AT&T_Mobility#Radio_Frequency_Summary
Frequencies used on the AT&T Network
850 MHz GSM/GPRS/EDGE 2G
1900 MHz GSM/GPRS/EDGE 2G
850 MHz UMTS/HSPA 3G
1900 MHz UMTS/HSPA 3G
700 MHz LTE 4G
So, the i9100 International will do almost all. Except LTE.

Thanks for your information.
Title pretty much says it all. What's the real story on the the 3g frequencies? Nokia's site indicates it's quadband 3G, but yet many of the stores seem to indicate that it's tri-band for 3G. I would like to get one for use on ATT, but I definitely need 850MHz 3G since that is the predominant frequency in my area.
Anybody? What's the real answer on this?

Thanks for the responses everyone. I think they just add to the confusion on what the real answer is, or Nokia is producing multiple models with different frequencies which I've seen referenced elsewhere.
I might just hold off for the 900 or wait until CES in January where they are supposed to make their big splash for the U.S. market. The render of the Lumia 900 that hit wmpoweruser today certainly looks nice if it's true. I wouldn't mind a slightly larger screen if it doesn't make the device too large. Some of the current phones border on mini-tablet size!
I know of two types of Lumia 800's and you can differentiate them via their FCC identification.
The European edition, FCC ID: LJPRM-801:
GSM/EGSM : 850/900/1800/1900
WCDMA : 900/1900/2100
The North American edition, FCC ID: ...RM-819:
GSM/EGSM : 850/900/1800/1900
WCDMA : 850/1900/2100
I really wish Nokia would fix the data on their web pages. I ran into this a few years ago with another phone I purchased from them where it was advertised as having U.S. bands when in fact it did not. Thanks for the info everyone.
Agree 100%. When i bought my phone, the lumia was advertised as:
WCDMA: 850/900/1900/2100
Many sellers have since correctly identified which bands the phone supports, but some still falsely advertise both 850 and 900 bands being on the phone.
When my Lumia 800 arrived and I could only get Edge/G service, I did some research and I was slightly disappointed. Luckily I work and live in a Wi-Fi zone, so that is my primary data connnection.

You too, huh? I was curious about Rogers. I find that 2G isn't the end of the world.. Only shortcoming are media rich sites, otherwise they still load up quickly for me.
The only thing I really would have missed on 3G is mapping and navigation, but the non-data GPS and preloaded map feature has completely eliminated that concern.
Rogers here in the 'Peg. I'm in love with it even though the primary service around my home is Edge/G. However, since I wrote that piece above, I grabbed the "Nokia Network Setup" application from the marketplace and now I can get 3G around my workplace.
Here is my situation at the moment. I'm currently in the US using At&t's network through straight talk. I purchased the Nokia Lumia 800 the UK version which is LJPRM-801. It clearly states that it supports WCDMA 900/1900/2100. Which I suppose are really meant for the UK or Europe. When I purchased the phone from the seller he clearly stated it was lock and he got it from Orange UK. Which I assume is locked as well. Surprisingly when I received the phone I inserted the Sim and it registered perfectly fine. I get voice AND data. I figured it may possibly be using the 1900 band for data. My main thoughts about this UK version is it may possibly have the 850 band included but not listed on the box for regulation concerns. How would I go about and truly testing it out if it does support 850 band?
You can't really, short of going to an area you know uses soley 850Mhz 3G, and not 1900 as well.
I dont see the reasoning behind manufacturing two different phones, My thoughts are they could have just disabled the band with a simple firmware. Has Anyone truly tested this? Any though on getting a different firmware version of the Lumia 800 on this UK version seeing if it would enable the 850 band.
Me too I purchased one from Clove.co.uk. On the box it stated 900/1900/2100 for 3G but I have 3G. Maybe I have a 1900Mhz station near my work. I will do more tests tonight.
Does an app exist to know the current band of 3G connection?
I've called Nokia while in Germany and they said that they only produced quad band Nokia lumia 800's

When you say quad band are you referring to 2g or 3g? because we know it's quadband 2g, but whether it's quadband 3g is the question.
So I have used it on 3 different locations here in Montreal on Rogers and I always got 3G. I don't know the band used by Rogers. I found several references but not definitive answer. I have the Lumia 800 Model 801.

Both 2g and 3G
So you have the lumia 800 which has quad band 3g? If possible could you please post a picture of the lumia 800 box listing the quad 3G bands?

I'm in Germany right now and don't have the box. I don't remember if it had the cell bands on the box. I know I got hspa on AT&T and I was happy.
Ok guys I have an atrix 4g running on t-mobile. My question is why cant I get 4g/3g on this phone ? T-mobile runs on the 2100 band and the phone does support that band so why no 4g or 3g? common sense would tell me that if t-mo runs 4g on 2100 and the phone is capable of running on 2100 that it would work. have searched for a total of about 4 hours or so over the past couple days and cant find a straight answer only thing i can find is that att doesnt run on 2100 band yet the phone does. thanks in advance to anybody that can answer and taking the time to read.
are you getting H+ or H? (This is "3.5g") The Atrix 4g is not a true 4g phone.
Because the 2100 spectrum that you're using the phone on now is part of the quad-band gsm which is edge/2g. The difference lies in the bands used for 3g/4g, in which case AT&T only uses 850/1900 and tmobile only uses 1700/2100.
There is also a bunch of things that include HSPA, AWS, WCDMA, and so on and so on but I don't know enough about that to comment.
EDIT: Also, the only phones I know that can be used on both AT&T and Tmobile 3g/4g are "penta-band" phones like some European Nokia phones and the unlocked Galaxy Nexus that needs to be imported as well.

Wcdma=utms=3g
Yes, WCDMA and AWS(1700), as far as I know, are both from UMTS and the differences in regards to 3G between AT&T and Tmobile lie in the spectrum use (850&1900 vs 1700&2100). And both AT&T and Tmobile use HSPA(+) based off their respected UMTS frequencies.
I just don't understand the "leap" in GSM technology that breaks the quad-band compatibility, that's all.

Also I've read 850 is att's main spectrum for large areas and 900 for T-Mobile. All higher spectrums are for smaller, rural areas.
If your looking for 3g maybe find a town or, buy a dual band amplifier? That's IF they have 2100 MHz band working where you are located.
Lower bands ie 850/900 are the download streams. 1700/1900/2100 are upload streams. If I'm not mistaken
Also a T-Mobile vibrant supports att, it also has our main band, 850mhz. Again which is the main large areas, like T-Mobile 900mhz. 1700-2100mhz for att/T-Mobile range is only as good as the towns that still has that band currently operating for hspa/3g data. I've seen alot of T-Mobile phones that have 850/1900/2100, and work on att. If they were 1600/1900/2100 did not for me.
You need that lower frequencies to ensure it to work. Then....
Also for regional based frequencies...
http://en.m.wikipedia.org/wiki/Universal_Mobile_Telecommunications_System
That link will let you know what that all really means.
I think you are mixing up gsm and umts.
GSM = 2G/Edge
UMTS (HSPA, HSPA+, HSDPA/HSUPA, WCDMA, AWS) = 3G
Have a look here. You will see they label "3G" as "UMTS" which is HSPA/WCDMA. A little more down you can see they label their data as "HSDPA", which is download, and "HSUPA" which is upload. Further delineating the speeds they label either one as UMTS for down and Edge as up, which to me tells me they use gsm for the upload and only use UMTS for download. Either way, there is not a T-mobile phone available that can be unlocked and used on AT&T's 3G, just 2G and vice versa. As I have previously mentioned, you will need a penta-band phone for that.

And don't get me wrong, I'm not trying to give anyone a hard time but it's misinformation to tell anyone that a T-mobile phone can work on AT&T 3G.
And I'll say it again, I'm not an expert so if anyone can better explain then I'm all ears (eyes).

I am just merely stating that I have a motorola defy on ATT, and it worked great for a long time with great speeds before I got a motorola atrix and infuse.
Im not saying that every tmobile phone will have working talk/text, or data for that matter. I have just posted an idea, or atleast what to look for when you are cruising for phones not labeled for your carrier.
I was getting my motorola defy with the att "grand fathered internet" for 10 dollars a month and it was about 160-420KB/s down, and 80-190KB/s up. but some phones are capable of this, others arent. I have a general idea, and have played with several different carrier cellphones and used them with att and att's 3g data.
Rogers HTC Dream (x2 of them)
Telus Milestone
Tmobile Defy
Rogers Atrix
ATT Atrix (x2 of them)
ATT Infuse
Rogers and Telus actually use the same 3G bands as AT&T so as long as those are unlocked they will work. And I'm not saying an unlocked T-mobile can't work on AT&T, because they can (they both use quad-band gsm) but you can not use an unlocked T-mobile phone an AT&T 3G. That's all I'm saying.
Now, they did make an European version of the Defy that uses the 850 3G band but not the T-mobile "branded" one.
I'm going to stick to my guns on this one because I don't want to give anyone the wrong idea about interchanging AT&T and T-mobile phones and expecting 3G service. I'm fairly certain about this and unless someone can prove otherwise that's how I will think.

Upon further research, I have found this article, where under certain circumstances, you can use an unlocked AT&T iPhone with T-mobile 3G:
http://www.gsmarena.com/tmobile_usa_running_1900mhz_3g_in_some_areas_iphones_invited-news-3537.php
Now, this shows that an AT&T phone can maybe use T-mobile 3G but not the other way around. Again, I'm always up for learning something new but I need references/proof.
Well I do get att 3g on the defy and vibrant. I am currently getting about 300ish KB/s on them and 600+KB/s on my attic, I'm just going with the facts. Those facts are that certain T-Mobile phones will work with Att, provided they have 850mhz band. That allows you in most towns (near me) to get 3g
False.
300KB/s is Edge speed, which is only 2G.
http://en.wikipedia.org/wiki/2G
http://www.phonescoop.com/glossary/term.php?gid=107
That's why you get faster speeds on the Atrix because it actually uses 3G.
Again, both AT&T and T-mobile use quad-band GSM. Which is why you can unlock a T-mobile phone and use it on AT&T, and vice versa, but it is only 2G/Edge and NOT 3G.
http://www.phonescoop.com/glossary/term.php?gid=139
http://www.phonescoop.com/glossary/term.php?gid=3
Furthermore, here are the wiki pages for AT&T and T-mobile which both inlcude frequency charts outlining the technology (2G or 3G) each one uses:
http://en.wikipedia.org/wiki/AT&T_Wireless
http://en.wikipedia.org/wiki/T-Mobile_USA
Here are the charts:
AT&T:
Frequency Protocol Class
Frequencies used on the AT&T Network
850 MHz GSM/GPRS/EDGE 2G
1900 MHz GSM/GPRS/EDGE 2G
850 MHz UMTS/HSPA 3G
1900 MHz UMTS/HSPA 3G
700 MHz LTE 4G
T-mobile:
Frequency Band Protocol
850 MHz GSM/GPRS/EDGE 2G
1900 MHz GSM/GPRS/EDGE 2G
1700 MHz UMTS (W-CDMA)/HSPA/HSPA+ 4G (formerly 3G[34])
1900 MHz UMTS (W-CDMA)/HSPA/HSPA+ 4G
I check for facts and references, I'm only saying what I find in research.
Again, when unlocked, a T-mobile phone can use AT&T 2G/Edge, not 3G

Hello,
This is my first post so Ill try to be as concise and detailed as possible
Bought the Blu Studio Energy 2 on Amazon.com on sale did the border jump.. came back and found that it doesn't work on the Wind network.
GSM 850/900/1800/1900
3G:UMTS 850/1900/2100
4G:LTE 700/1700/1900/2600
I thought the 1700 and 2100 is what's important for Wind.
Is there a way to 'open' this phone up to accept the 1700 band on the 3G network.. because that seems to be it's only problem.
The CPU is the 'Mediatek 6735 1.3GHz Quad Core Processor'
Thank you guys.
:good:
ht tp://phonearena.com/phones/ZTE-Obsidian_id9566
this phone has the UMTS band 4 1700/2100 with the same cpu.
Am I missing something?
40+ people and not one reply
did i post in the wrong section? or is there no solution?

As far as I know, Wind does not have LTE, just HSPA+/3G. Wind uses 1700 and 2100 3G bands...so depends on your location, you may not have coverage if you are missing the 1700 band.
