T-Mobile US rolled out 3G - anyone able to get it on diamond?

...any luck? any radio updates for this?

I am a US TMobile subscriber, and here's what I know:
TMobile has only released 3G in a handful of cities, including NY, Vegas, and Houston (or maybe it was Austin).
Tmobile US runs on UMTS 1700/2100.
The Euro version of the Diamond runs on UMTS 900/2100. However, this 2100 band is supposedly "different" and will not run on TMobile US.
And the US version of the Diamond runs on UMTS 850/1900, which is what AT&T uses, and that won't work on the TMobile 3G network.
Long story short: no you won't get 3G with TMobile.

I have gotten 3g to work on tmobile but not in nyc. It was actually in central nj by philly. I took a few screenshots but not uploaded them yet. i got radio 1.25.05.

Great, could you please post the screenshots as well as your ROM version?
Dimond supposedly supports 1700 so not all is lost I think.

do you have an european diamond??

I'm sure if it's true, we'll get more confirmations to back him up.

Might road-trip to vegas to find out.

mi HTC es para Europa, DIAM100
tu tienes el DIAM110 para USA?

I just got my "US version" and it's WCDMA 850/1900...
And I can see "G" icon coming up in "some" place.
But most of time, I only can get "E"....
I am sure my city already got T-mobile 3G service,
Because my friend who got a T-Mobile NOKIA 5610 ( 850/2100 ? )
His phone can always get a "G" coming up, and we tested the up/down speed
it's 153 / 42 kbps something.
I really want to know how to make mine working.

G is actually bad, it means GPRS not even EDGE (E) and the speed you posted is way to low for the 3G which should be a few MBPS actually.

Victor, the "G" is GPRS, not 3G. "E" is EDGE, which is a bit faster than GPRS.

I got G... but when I went to the info on top it didn't say GPRS... it said T-Mobile 3G...
I have a htc diamond 3700 DIA100.
Same as above post, I get G sporadic around philly, but it says 3G not GPRS in the info.

I think that's just the name of the data network. Your actual data connection would have a 3G icon if it were 3G.

my diamond is from hong kong.
i have t-mobile and live in new york city.
when i look at the top of the screen i see the [E] icon, and next to that, the signal bars with an E above them.

I don't think the WCDMA work on 3G networks. Different technology. I also don't think the regular US GSM phone will work on the tmobile network. Different wireless bands from AT&T...

I don't think any of the Diamond (US/Euro version) will work with US T-Mobile 3G, only PDA phone that I am aware of is the SonyEricsson X1 with 1700/2100 band.

WCDMA is the air interface used by UMTS & HSDPA so it is what we need/use for 3G on AT&T (and T-Mobile - just on a different frequency.)
On all WM phones I've owned I've never seen the choise of choosing UMTS or HSDPA in phone settings. You always get either AUTO, GSM (straight GSM or EDGE) or WCDMA (UMTS or HSDPA). And, when choosing WCDMA I will get HSDPA (as long as I'm in an area with it, of course.)

Help! 3G is not working after Hard-SPL and unlocked TP2

I'm new here and I enjoyed this site very much. I have one problem with my TP2. Somehow, 3G network is not working after I installed Hard-SPL and unlocked T-Mobile TP2 switch to AT&T sim card. Everything is working fine with AT&T's sim card I was able to made phone calls, received, SMS, and web browsing. ATT 's 3G network is available around my home, but I can not get 3G on TP2 instead a EDGE network. Can unlocked TP2 handle AT&T's 3G network? or a .cab file I can download to fix this?

idk for sure but i think t mobile uses a different frequency for 3g from at&t so if they are you are stuck with edge speeds on at&t man sorry

I have the tmobile TP2 and i can confirm from talking with ATT that the phone does support ATT BUT i was unable to use the phone on 3g. The phone DOES support the signals for 3g but am still unable to access the towers in my area. I think the phone may be hard set to look at tmobile towers, is there any way i could reset the device to open up its tower usage? Hopefully i can get an answer but no tmobile TP2 users arent screwed in the US we just need to find a fix

It was my understanding that the tmobile tp2 does NOT have 850/1900mhz 3g on it. It does have aws 1700 for sure. Not sure about 2100mhz though for overseas.

This issue has been covered many times in the numerous AT&T threads on this board.
I'm sorry to tell you that the T-Mobile TP2 hardware radio was limited to using 3G over the 1700/900Hz frequencies, while AT&T currently uses 1900/850Hz only. It's unlikely that any change can be made to the radio software wise to fix this issue.
Just to make things clear the issue has nothing to do with Hard SPL or custom roms.

T-Mobile UMTS 1700/2100 Mhz
T-Mobile 3G runs on UMTS 1700 up and 2100 down. Unless you have a device that runs on those specific frequencies, EDGE is the best you can do with T-Mobile if you opt to run on their service.

ATT offers UMTS or 3G using 850mhz(the old TDMA band) and 1900mhz. While T-mobile offers HSDPA (technically 3.5g part of the UMTS specification) using 1700MHz for uplink and 2100MHz downlink.
Because HSDPA is part of the UMTS spec, it’s backward compatable. However, you have the limiting factor beging that the frequencies the individual carriers use to transmit the data.
Europe and Asia’s 3G runs on 1900/2100mhz. North and south America is supposed to use the (AWS) 3G spec using 1700/2100mhz
ATT didn’t want to wait, like T-mobile is doing, for homeland security to vacate those frequencies and launched on 850/1900mhz instead

I heard that t-mobile did not have enough spectrum in many areas to launch 3g in its existing 1900mhz. At&t doesn't have that issue, or as bad.

Im gonna make this real easy for u. The tmobile tp2 will not work on at&t 3g. The 3g bands are different

Telus TP2 Radio(s)

Exactly what cellular radios does this phone [Telus TP2] have?
My carrier [Telus] has recently completed their 3G overlay, and I'm still showing "EV".
Should I be talking to them about fixing this, or...?
It was (is?) my understanding that this phone was fully 3G capable.

Can someone help me with this?
As far as I can tell, my phone should support the Telus overlay of HSPA on their CDMA network, however I'm showing "EV" an my network type on the notification bar.
I visited a Telus store, and talked to a rep, who just babbled to me about how my SIM was "registered" as a CDMA phone, and therefore I couldn't use HSPA.
>_>
Thoughts?
EDIT: The rep also fed me this convoluted bullsh*t about how when I'm roaming, I'll be able to be on HSPA networks, so I'll get better bandwidth roaming than on my home network...

Wow no one knows the answer to this?
I've searched, and there's no answer, per se, just descriptions of Telus' technology and the antennae in the TP2, which seems to indicate that the TP2 should be able to get on the Telus HSPA network...

I have a SIM-unlocked Telus Touch Pro2 I bought off Craigslist, figuring it'd be good to go when the HSPA network rolled out (Only four months later!). As I understand it, the telus model can make and receive calls on quad-band GSM frequencies, but only use EDGE speeds for data. Has to do with the firmware for the chipset inside the phone. The only HSPA 3G band the phone can use is 2100 Mhz, which is the bad used in Europe, not Canada. It's a major piss-off, especially when a month ago the stores made this out to be the top-of-the-line phone, perfect for ever and ever.
It would seem that should Telus decide to plug in some firmware upgrades, they could activate the new 3G bands, but why bother? We've already signed away our souls to the company.
Who knows, maybe they'll fix it when they release Windows 6.5 for our rig. Because that's on the top of the to-do list, right?

Well there are new radios that we could flash...would that change anything?

Now I may be misinformed but I think that the Telus version is a CMDA phone with GSM capabilites on some frequencies. I do not think it will work on HSPA in Canada as they use different frequencies (850 and 1900). This is why so many people were waiting for the ATT version to come out as it uses those frequencies.
Remember GSM does not equal 3G.

What I would like to know is whether the distinction between 3G and GSM is on the hardware side, firmware side, or software side. Telus would have you assume it's all the hardware's fault, but I'm not sure on that one.

From everything I have read its the chip in the phone that isnt programmed/capable of doing the frequencies required. It may actually be a second chip but I cant confirm that. Other posts have stated that there wont be a software fix to "unlock the frequencies" needed.
GSM is a cellular line and 3G is a data connection.

I just purchased an At&t Tilt 2 unlocked for use on Telus 3G+ network. The Telus Touch Pro 2 is a CDMA , Quadband GSRM and UMTS/HSDPA 2100. The Telus TP2 will only work with EVDO data on the Telus network. If you unlock it for use with Rogers it will work on GSRM with Edge data. That is why I have ordered the At&t Tilt 2. Unfortunately Telus won't honour my unlimited data plan and say it is only for EVDO and that I have to change to one of their current plans to have HSDPA. Like all of the networks, they get your money one way or the other. I'm pleased that with the Tilt 2 I am free to switch providers here in Canada and still get 3G as well as when I travel in Europe.

Xperia play 4g on tmobile usa

Hey I was wondering if u unlock sim card on the at&t xperia play if it will connect to tmobiles 4g or at least the 3g, I will be gettin the r800at soon and wanna know if anyone has it on tmobile and if they are getting 3g or 4g.
If someone already posted this I'm sorry I searched but couldn't find anything
Thanks

You'll be getting EDGE or 2G whatever you want to call it. T-Mobile runs on a special frequency that AT&T doesn't.

That sucks that's the reson I wanted the r800at ohwell thanks for the info

Hope 3g or 4g will work once the merger happends with at&t and tmobile lol

T-mobile in the US uses the same band it uses in the UK. Thats why it differs from the other US GSM networks If you buy a EU device you can use T-Mobile 3G.

I dont mean to rain on anyones parade, but i thought id go and check this out because that didnt sound correct.
Tmobile 3g seems to require the AWS band, no available model of the xperia play carries that band.
Tmobiles setup uses one band for uplink and one for down, not one or the other, these bands being 1700 and 2100, the r800i carries 900/2100 and the r800a and r800at carry 800/850/1900/2100.
as you can see theres no 1700 band available on any xperia play model afaik. so it appears you might be sol sorry :/

Thanks for all the info so its stupid tmobile that sucks they should have just came out with a tmobile one when the one for at&t came out such jerks well at least I can play games lol ill just have to conect to wifi when I wanna download stuff or watch videos ohwell

T-Mobile needs to step up and get OFF 1700! NOBODY uses that freq! I WANT 3G

Hell ya I agree I only got tmobile cuz they had the sidekick 2 back in the day and just never changed kept doin the 2 year contract thing ohwell

When I flashed my R800at to 2 different generic stock firmwares (which changed my model number to R800i & R800a)my mobile connection changed to Edge. It also changed when I went into the settings>network mode& change it to "GSM only". It only went back to H or HSPA & 3g when I changed the APN's & changed network mode back to WCDMA (preferred)/GSM. Does that mean that the AT&T XPlay can connect to an Edge(2g) network but not Tmobile's 3g network?? What if we changed the APN? If anyone tries this please post the results here.

Ok so I was wrong & I can confirm that the Att Xperia Play will not work on Tmobile's 3g or 4g under any circumstances. Only edge/2g data will work due to the difference in bands as was mentioned here.
Sent from my R800a using XDA App

well... that sucks. looks like i'll be getting an amaze 4g when i get back from Africa in spring!
(i only ordered the no-contract AT&T xperia play 4g to use on the "orange" network here, i don't want to have AT&T in the states. only t-mobile and verizon have 4g in my area, and i want to keep GSM for next time i travel, so t-mobile it is)

Unlocked sprint g8 no 3g or hspa

Im using this phone with cricket but for some reason it won't connect to 3g or hspa do anyone know why?

Perhaps because regular 2G, 3G or the faster 3G HSPA(+) on AT&T's network runs on GSM technology which is completely incompatible with the CDMA network Sprint uses for those technologies and the firmware on the Sprint variant is artificially limited to only be able to connect to CDMA and not GSM even though the phone's modem has the capability? Take what I'm saying with a grain of salt however.

Yes, because LTE is its own technology. LTE, GSM and CDMA are each their own technologies, each completely different from the other in a multitude of ways. That's what makes one not compatible with the other, but with the advent of LTE it also made it much more cost-effective for device manufacturers to include 4G support for all major networks (provided the device supports the necessary bands and the carrier allows it, of course)... so yes, LTE should work flawlessly.

The specs on the LG Official Website for Sprint LG G8 shows it has all the 2G, 3G, and 4G bands on Cricket except it's missing B30 for 4G:
LTE Bands 1/2/3/4/5/7/8/12/13/17/20/25/26/28/40/41/46/66/71;
CDMA Band Class 0/1/10;
GSM 850/900/1800/1900 MHz;
UMTS Bands 1/2/4/5/8
Did you try to change the network mode to GSM/UMTS and reboot?

Yeah thats what I thought too but even after changing the network mode and restarting still not getting 3g data

Yes you can dial *#*#4636#*#* , go to phone information or network, look for preffered network, then select wcdma preferred, it will switch to hspa+, do note there will be no indication, only a 3g symbol on the bars. if you download network info app, it will let you see that you are indeed on hspa

Ok after many attempts to bring up my 3g inwas able to do so by going into ##data# and resetting the apn then boom 3g icon popped up. Weird because the apn was correct in the first place prior. But thanks now it works

LTE. If you don't get good speeds (about 10Mbps) then change it to GSM. This is something I actually have to remember to do if I'm outside the house because I actually get more consistent performance inside my house using 3G HSPA+/GSM. On HSPA+ it goes to is 6Mbps which is plenty usable but normally it runs at 10Mbps which is more than enough for Full HD streaming whereas if I use 4G LTE under the same condition I'll either get 30Mbps or 1Mbps depending on the time of day and/or if the network is congested. 1Mbps is definitely not usable for anything but streaming at horrible quality or browsing basic webpages.
