Hi guys,
I am on T-Mobile prepaid plan. I bought a Lumia 920 from Singapore few months ago in anticipation of the 1900 refarm from T-Mobile. But while the default APN profile has been updated to "T-Mobile LTE" from the carrier from months ago, the max speed I see now is 3G in Chicago. I've done some research and tried a couple of the following:
1 Added new APN under epc.tmobile.com
2 Enable ENS
3 Limit the connection speed to 3G instead of 4G
But none seems to bring me to the LTE speed. I thought maybe because LTE has not arrived in Chicago yet, but few days ago I went to one of the T-Mobile store and found that their demo Lumia 925 showed LTE. The stuff from the store said because I am using an unlocked 920, LTE is not supported. I don't think this is the right answer.
Does anyone has the same issue with your international 920 under T-Mobile in the US?

What version you bough RM-820, 821 or 822 from Singapore. I think you have not supported LTE bands, so probably you got 821 / 822

Wow I just checked, it's indeed a RM 821! I did a search and found the following info from WP Central forum:
RM820 is the North American variant. Has pentaband UMTS (850/900/1700/1900/2100) and North American LTE bands.
RM821 is rest-of-world (except China). Has quadband UMTS (850/900/1900/2100) and European LTE bands.

My understanding is as long as it supports 1900 band it can access the LTE speed on T-Mobile. That's not the case then?

Just because it supports the 1900 band, does not mean that the ROM and hardware are setup to support LTE. The market the 821 was released for does not have LTE so the protocols where never implemented in that model. The 3G you see the phone operating at is the highest speed the market it came from supports. So that is the highest protocol that was installed into that model. You may want to sell it and get one of the other models.

Hi t_huankiat,
To the extent of my knowledge, T-Mobile has only deployed LTE on the 1700/2100MHz frequency band (different from 2100MHz, that is IMT) commonly known as AWS spectrum or Band 4. The only variants of the 920 that contains these are RM-820 models. The good news is, an unlocked AT&T Nokia Lumia 920 can be used on T-Mobile's LTE network because they both use AWS spectrum to deliver LTE service. The downside is that in areas without LTE or refarmed HSPA+, your service will drop to 2G. In order to prevent these shortfalls, the only RM-820 variants that run on AWS HSPA+ are the Canadian and Developer Edition, given out at Microsoft BUILD 2012.
You may be thinking, what is with this confusion. Previously, T-Mobile USA rolled out their 3G HSPA network on AWS spectrum, because they hadn't won any PCS spectrum (1900MHz). In the Americas, AWS spectrum was not deployed as prevalent as PCS. The result, T-Mobile required special handsets to access 3G. When they transitioned over to HSPA+ and DC-HSPA+, they continued to use AWS widening the compatibility gap. After the AT&T/T-Mobile buyout fell through, T-Mobile gained PCS licenses as part of the deal. T-Mobile, shortly after, announced the jump to LTE and the refarm of HSPA+ (current 3G/4G service) to the PCS spectrum. As of now, the refarm isn't fully complete so some areas still broadcast 3G/4G on on the AWS spectrum. To add insult to injury, these areas do not have have LTE deployed either. Summing up what has been said, the best options for a seamless wireless experience is to use a Nokia Lumia 925 or find a non-AT&T RM-820. If you look on eBay, you will find a few for sale right now. I really hope this helps!

I should have done more research before I bought the phone! I did not realize 920 has so many variation even in Singapore! While I will miss the LTE, I can live with 3G speed since I don't use the phone for streaming or anything bandwidth intensive.

The main reason I got the phone from Singapore was because it supports 1900MHz and it's in Chicago now. But I overlooked the fact that the ROM matters too. So now I am pretty much stuck with 3G speed. It's a lesson learned, I will have to be extra careful next time when I get an unlocked phone. Thanks for your insight!

Don't worry, you will still be able to use their DC-HSPA+ network, where available. This technology is capable of up to 42.1Mbps theoretically. Even before T-Mobile began deploying LTE, their DC-HSPA+ network was usually testing faster than Verizon's LTE network. While you may not see LTE until you upgrade to an AWS capable handset, their "fallback" 4G should suffice.

Hey guys, I just got my new HTC hero. I'm with AT&T now and having the unlimited 3G data plan. I setup the configurations of APN settings as following:
Access point: wap.cingular
Username: [email protected]
Password: CINGULAR1
But I only see an "E" at the connection status which I believe indicates EDGE. Can anyone tell me how to get 3G work on this device?
Thanks a lot!!!
I didn't realise the hero was out in the us yet but if it is i don't know why and if it isn't out its because i don't think it surpports american 3g networks i think you can only get 2g.
Yes I got this phone out of the US.
So you mean there's no way at all to get 3G to work on this phone with AT&T or any other carriers?
In its current state the phone does not support the AT&T bands for 3g.
There are rumors of an AT&T version coming October 11th, that would support 3g.
European/Asian version of this phone does not work with US 3G. AT&T's 3G network requires the bands 850 & 1900, while T-mobile's 3G requires the bands 1700 & 2100. European/Asian version supports only the bands 900 & 2100.
Does this mean T-mobile 3G may work on this phone?
T-Mob's 3g should connect to this phone, if you could find a signal, haha.
http://www.androidauthority.com/index.php/2009/07/03/htc-hero-approved-by-the-fcc-with-att-3g/
Neither T-Mobile US nor AT&T will work with this phone for 3G. The only version of this phone that exists at the moment supports ONLY European 3G. There are rumors of the device coming to AT&T, but nothing confirmed. IF that happens, the new phones would work, but that wouldn't change the fact that the device you have will still only function on Edge.
Sorry to be the bearer of bad news, but it's true.
It's actually Sprint pal. Also, there was a picture for Tmobile also (this appears to be a rumor).
T-Mob uses the 2100 spectrum so i dont see why it wouldnt work.
And a CDMA and a GSM (With AT&T 3g bands) has gone through the FCC recently.

No, it won't work with t-mobile USA's 3G network.
Yes, T-mobile in Europe use the 2100 band for 3G so the Hero works. But T-mobile USA use 1700 and 2100 bands for 3G, and you need a phone that support BOTH bands to connect to its 3G network.
Unfortunately, unless T-mobile USA decides to carry this phone (and they have already said that they wouldn't), there won't be a version of Hero that support its 3G network. This is because T-mobile USA is the only carrier in the world that uses the 1700 band for 3G. You may ask why T-mobile uses different bands for 3G in different countries. This is more of a regulatory decision than a business decision. If you are interested, go read about those FCC spectrum auctions.
All in all, European/Asian version of the Hero won't work with any 3G network in the US. The product id of the European/Asian Hero is HERO100, it supports only the bands 900 and 2100 for 3G. There will be a North American version with product id HERO130 that supports the bands 850 and 1900. It will be released either on AT&T or on the Canadian carrier Rogers, because only these two carriers use these bands for 3G. Currently it is not know whether it will be on AT&T or Rogers, but that latter is more likely IMO. Finally, there will be a CDMA version, with product id HERO200, for Sprint. This is more or less confirmed to be coming in October.
T-mobile US 3G uses 1700 for down and 2100 mhz for uplink. So 2100 alone isn't enough as you need both directions to connect.

Thanks! That was very informative, although it totally crushed my dreams of owning a Hero while remaining on the T-Mobile network.
This may be stupid, but I can't find the answer in this forum.
I am drooling over the Titan, but am with T-mobile US and can't switch anytime soon.
If I buy a Titan 3rd party, can I use it for voice and data on T-mobile? Will I get full speed data?
Thanks.
You will get voice and data, but only 2G speeds. That goes for both the international version and att version.
Any info on some kind of quad band version that will work on both AT&T and T-Mobile?

Titan is quad band according the htc.com
HSPA+/WCDMA 850/1900/2100MHz and Quad-band GSM/GPRS/Edge 850/900/1800/1900MHz
Shouldn't this work then? ATT's specs also say 850/1900/2100 MHz for HSPA/UMTS. T-mobile's HSPA/UMTS is on 1700/2100 MHz (according to Wikipedia). For the 2100 band, it should work, right? I am unsure as I am a simpleton and just comparing numbers and assuming that is all that has to match.
I would guess this would require an unlock.
T-Mobile uses both 1700 and 2100 bands for their 3G/HSPA+.
This is why it will not work.
I know because it pains me to not be able to get this device on T-Mobile.

Go with AT&T GoPhone if you have Titan (Simfree), i am enjoying Unlimited All, (Call + Text + Web 4G ) with only $50 a month . Titan can get HSDPA+ (i think) on AT&T.
Im using the titan, unlocked on t-mobile and it does run on edge. honestly its not tooo terrible but edge sucks. and i cant get picture messages. idk i just might keep my hd7, sell this phone and wait for something better on t-mobile that i can actually use hahah but i love the giant screeen
Does this mean the Titan would get 3G or better on T-Mo US now?
http://www.phonearena.com/news/T-Mobiles-consolation-package-3-billion-7-year-3G-roaming-deal-128-AWS-markets_id24956
AT&T and T-Mobile UMTS Roaming Agreement
AT&T and T-Mobile agreed to roam on each other's UMTS bands for the next 7 years following the formal withdraw of AT&T's merger offer. As to when that becomes effective I do not know; I've yet to get an answer from either AT&T or T-Mobile on the subject and that's assuming they'll tell you; it takes an act of God to get through to AT&T's equivalent of T-Mobile's Tier 1,2 and 3 tech support. We have both AT&T and T-Mobile; and in the here and now, neither are compatible on each other's high speed bands; I have the Titan with AT&T and the Rhodium with T-Mobile; my Rhodium unlocked for use on AT&T and despite 3G in Columbus, GA and Auburn-Opelika, AL; I can only use Edge on AT&T. On my Titan it's either "E" or "4G", no 3G. What I have noticed is the Titan favors 4G and seeks those towers which is great if you're in the city, but rural; forget it. It's all Edge out here. It will hit the T-Mobile tower which is 4 bars in our Opelika location but immediately go to either no service or a 1 bar sometimes on 4G and others on Edge. We all know that "4G" isn't 4G and of course "Unlimited" isn't unlimited and politicians and marketing gurus think we're all stupid.
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.

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

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.

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

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

Since Nokia does clearly say everywhere else except the US that 920 does support 1700Mhz (for obvious reasons), I wonder if the hardware in the AT&T version will be the same as in the int'l version and it'll just be a matter of unlocking the phone to use it on TMo.
Opinions?
I noticed that too!!
Its now PentaBand WCDMA/HSPA+ at 42Mbps. They added WCDMA 1700Mhz band on the specs.
Originally when the phone was announced last month was listed as QuadBand WCDMA missing the AWS band at 1700Mhz.
If this is true it means one of the following:
1.The band was always there and for some reason software locked and they decided unlock it and release it as a PendaBand.
2.They listen to the complaints (pretty much the same way they did and released the Cyan Color) as the missing AWS band was one the biggest complaints especially from T-Mobile USA subscribers and they decided to include it as well.
3.It is just a typo and Lumia 920 is still QuadBand HSPA.
4.It was a typo from the very beginning and Lumia 920 was always PentaBand.
Now assuming the the phone is PendaBand HSPA+ it will perfectly work with T-Mobile USA current 3G at AWS and with the reformed Network at 1900 they are preparing. It will work with both at 42Mbps speed.
The original unlocked Lumia 920 listed the following 5 LTE bands 800 / 1800 / 2600 / 900 / 2100.
If the unlocked phone comes with those LTE bands will be incompatible with T-Mobile USA upcoming 4G LTE network.
However the American model which AT&T will carry exclusively has the following LTE bands 700 / 850 / 1700 / 1900 / 2100
If Nokia also release an unlock/unbranded version of the American model with the above LTE bands and PentaBand HSPA+ this model along with the 42Mbps HSPA will also support T-Mobile's upcoming 4G LTE that coming mid of next year with theoretical speeds of 100Mbps.
Releasing this device will be the perfect option for T-Mobile subscribers as it will be future-proof for their upcoming LTE network.
I am curious to see whats really going on here. Meanwhile I am crossing my fingers. :good:
So Nokia needs to release a international us version?

Unlocked/Unbranded version of the American model is the correct way of putting it.
Nokia used to have to versions of the unlock devices in the past. The regular version which was usually the European/International model and the NAM versions for North America.
Many devices came like that in the past including the N95 & N95 NAM, 5800 & 5800 NAM, N97 & N97 NAM etc.
All had QuadBand GSM and different bands for 3G, the NAM versions had the American bands for AT&T USA and Rogers for Canada.
Now that PentaBand is standard for 3G/WCDMA, they need to release (and I hope this is the case) the European Model with the European LTE bands and a "NAM" model with the American LTE frequencies.
I guess time will tell what exactly the case is going to be.
But again this is for LTE. Assuming that the information on the spec-sheet is correct and the Lumia 920 comes with WCDMA/AWS 1700 then it will work perfectly with T-Mobile USA and AT&T's HSPA+ at 42Mpbs.

Unfortunatly number 3 is the correct answer.
According to WPCentral.com the AWS 1700Mhz WCDMA support for T-Mobile 3G that listed in specs are just a typo on the website.
If this is the case, you can still use the Lumia 920 under T-Mobile 3G at 1900Mhz.
T-Mobile is reforming their Network and releasing 3G to 1900Mhz now, the problem is that we do not know what markets/areas has this already or how fast the project is moving on and when it will get complete..

That's wrong, because this phone will be using the Snapdragon S4 Plus (MSM8960) which uses Software Defined Radio (SDR) for determining their bands. Obviously you cannot use all at the same time, but any one at any time. The HW supports this (according to the Qualcomm reference design), and if it hasn't been supported before in this chipset, it's probably due poor modem programming and/or unstable behavior, and/or band/bandwidth throttling by service providers networks. It's also an efficient way to make sure your Verizon mobile cannot use AT&T networks and vice verse...

That is why I said its Number 3, according to WPCentral. I am aware of the SDR in the latest generation of Snapdragons, however as its name mention its programmable, meaning they may have turn off the AWS...
For me it doesn't make any sense to list the phone originally with QuadBand WCDMA and then add AWS and list it as a PentaBand.
I mean if it is wrong and its missing the AWS that is making the original listing with QuadBand the correct one, so why they bother changing it?
In the other hand if the SDR scenario applies and the AWS is already there, they may just heard the complains and simply turned ON the AWS band, that is why they added in to the specs meanwhile the Nokia representative that WPCentral reached may not be aware of the new specs yet...
All these are different scenarios, unless we have an official clarification from Nokia, we cannot know for sure until Lumia 920 its been released.
PS. Can you post the link with the detailed specifications of the Snapdragon S4 detailing the SDR? The specs I found does not include any information regarding this. If I am not mistaken and remember correctly SDR is affecting LTE only and its able to catch from 700Mhz - 2600Mhz (for LTE), its programmable to deliver everything between these bands but limited to deliver 5 Bands at a time. I do not remember mentioning WCDMA to be compatible with the SDR, but I may be wrong on that. Please feel free to correct me if that's the case.
According to FCC documents, looks like AWS is there. Question... Will it be disabled in the AT&T version? Unlock possible?

I read that the FCC Documents for the AT&T model are mentioning AWS (1700) for LTE. This is normal as AT&T's LTE is operating also in AWS.
I didn't read anything regarding AWS for 3G/WCDMA.
If you read back, it specifically mentions wcdma 1700. Document differentiates between lte freqs and wcdma ones.

Is there an app or command to log the different frequency bands available in an area? I'm thinking of getting a Galaxy Note 2, but the Note 2 doesn't support the 1700MHz frequency band, and I'm on T-mobile. Any way to figure out if the new phone will get reception, other than just plonking down ~$650 and hoping for the best?

You will have EDGE coverage anywhere, but I wouldn't buy an expensive new phone that doesn't support 3G for your carrier.
Why aren't you buying via T-Mobile, that does support their speeds?

First, because the phone is at least $70 more expensive on T-mobile's store.
Second, even that version of the phone does not do HSPA+ over 1700 MHz (it's actually the same N7100 you see everywhere). The trick is, T-mobile is supposedly switching all of their 1700-band HSPA+ towers to 1900 band, partly in preparation for their LTE rollout and partly because that's the only way they'll be able to get the iPhone to work with their network, but they haven't gotten it done everywhere and I'm concerned that I'll plop down ~$600 on a phone that only gets 2G speeds at work.

You had me worried so I looked it up. According to the news sources I found, T-Mobile is converting it's 1900 2g towers to support HSPA+. So for the present the current 3G network is not in danger. I suppose my Amaze will continue working for a while!
Where did you see a report that they are changing out the 1700 band HSPA+ towers?
-----
"In May, T-Mobile's chief technology officer Neville Ray said the company would be repurposing its existing 1900MHz 2G service with 4G HSPA+, in order to "provide customers with the ability to use a broader range of devices, including the iPhone, on T-Mobile's 4G network.""

Almost every tech news site that discusses the 1900 band refarming mentions that the reason is to re-deploy 1700 for LTE (that, and to get the iPhone running on T-mobile because Apple outright refuses to make the iPhone pentaband for some reason). It's a fairly easy Google away.
