Search???? But it is some much better for the community to ask the question before searching.
Please close thread.

Before you start flaming, I suggest you read the question. Since you can search, I assume you can read...
The original question was about this service in Dallas TX, which according to multiple sources, the service was just launched on August 27.
Most posts available on Tmobile's 3G state the service is on the 1700 MHz (which the kaiser is not capable). However there are a few people that have stated it might also be in the 2100MHz band.
It is also possible that the Kaise is capable to hook to the 1700MHz band but not enabled by the radio rom. Take the Diamond for example, it was not supposed to support the 850MHz band...
Since Dallas service just started, it is possible 2100MHz is available.
Has anyone been able to prove Tmobile's 3G service is up an running IN DALLAS?

I stand corrected, kind sir. I jumped to a conclusion and was ignorant of the facts related to your specific part of the world. I am sorry.
Did you call TMobile customer service and ask the question? So none of the search results gave you any help. I guess wait and see if you get a reply. Good luck.

I just got 3G here in little old York, Pa. I guess I don't understand your question?

I think what he wants to know if 3g data will work with an at&T branded tilt on tmobile U.S. and if so I would like to know how it compares to the edge network they were using

i think T-Mobile uses 1700/2100 and one band is for uplink and the other is for downlink.
unlike AT&T or Rogers who can use 850 and 1900 independantly for uplink or downlink.

first of all, tmobile sim cards are not 3G compatbile, therefore even the correct settings probably wont pick up any 3G signal...keep in mind that tmobile never updated simcards since its voicestream transition...i remember when AT&T went 3G, they had to issue 3G enabled sim cards....

And my Tilt has a 3G SIM but it's an ATT SIM.

you cant get on tmobiles network with an att sim

the kaiser, t-mobile, and 3G

Hi everyone--
I have an unmodded, "unlocked" at&t tilt that has a t-mobile gsm sim chip in it. I'm still running the WM6 that came in it, and can't seem to get access to the 3G speeds I know this thing is capable of. I've tried numerous software apps to "force" the phone to go 3G, to no avail. T-Mobile customer "support"--HAA! tells me I need a t-mobile phone to be able to take advantage of the 3G speeds. Needles to say, I feel this is a bunch of malarkey. T-Mobile put out this phone, did they not, and called it the "MDA Vario III"? Is there a rom for the mda that I could flash this thing with so I could get the 3G speeds? Or another rom perhaps? Any suggestions would be most appreciated. Thanks!

Unfortunately, the malarkey is the truth! Because T-Mobile runs its 3G network on a different band than the Tilt is capable of! Sorry, this also effects me as I am a T-Mobile customer using a Tilt as well! My advice is to use Opera mini 4.2 for your internet browsing it is very fast on the Edge network!

The T-Mobile you refer to is European
It does not run on the same 3G as the US T-Mobile. The US T-Mobile uses 1700 Mhz and 2100 Mhz, I believe. The Tilt does not use the 1700 Mhz band. There was a rumor going around that there would be a new version of the Kaiser (KAIS140) that would use the US T-Mobile 3G bands but it was never released for sale. I don't think it will since it is pretty much at the end of the life cycle of the phone. They (HTC) have moved on to newer models with more features. If you would like to use the US 3G and live in an area with 3G, The T-Mobile G1 (HTC Dream) uses T-Mo 3G and has its own section on this forum.

bleh. newer models should still freaking tilt. that is the coolest thing about this phone. and it's pretty solid construction. my friend has had his over a year and its still going strong.

I thought the Tilt accessed 3G through it's tri band frequencies 850/1900/2100Mhz so that it could connect to most 3G networks worldwide, making it a world business tool for users?

True but T-Mobile uses the 1700 for upload and 2100 for download. ATT uses 1900 for both.

Tilt 3G on Tmobile network?

since the tilt is 3g, if i unlock it and use it on Tmobile does it still pick up tmobiles 3g or is it different? thanks alot

It won't grab T-Mo's 3G. The Tilt can find "standard" 3G, in the 1900 band, but T-Mo's runs on the 1700 band. There's a hardware difference as well dealing with the radio.
Basically, you'd be stuck on EDGE, like the rest of us Tilt users are.

ya i thought they were different thanks alot for the fast reply

[Q] ATT Nexus one on Tmobile

Hi everyone i tried searching but didn't come up with anything. I'm considering purchasing an unlocked nexus one on amazon and I'm not sure if its a tmobile or att version I have tmobile as my provider if i were to get an att version would i still get 3g access? I know if it was the opposite i there would be no access for 3g on att.
Thanks

I believe t-mobile's 3g is 2100mhz, which means the atnt one should work on the network.
I'd get a second opinion though, I'm more knowledgeable on Australian networks than US ones.

Ok thank you for the input, if anyone could confirm this that would b great.

The devices are completely independent of one another in regards to 3G. Cross network compatability only extends to Edge services.
Someone jump in and correct me if I am wrong, but I believe that T-Mobile 3G requires both the 1900 and 2100 frequencies to work (up & down link).

Rod3 is correct the at&t version will not work on t-mo and the t-mo version will not work on at&t, in respect to the 3G that is you will still get edge either way.
Although as far as the both 1900MHz and 2100MHz I'm not sure about that but it's possible, anyone care to add some info.
EDIT: Just Googled it and it's 1900MHz for 2G and 1700MHz/2100MHz for 3G encase anyone is interested.

Dude, thanks for the correction. I knew there were 2 frequencies for 3G and I just picked one off the top of my head. Now that I think about it, yeah 850 and 1900 were for 2G.

Verizon HTC 1 to T-mobile

Hey everyone. So i have a question that i can't find on here so im going to ask it. I have a Verizon HTC one unlocked. The sim car works fine and i can do everything on the phone with the T-mobile sim card. The issue is its always Edge data. Is there a specfic APN i have to use? something im not seeing? Does anyone else have this issue? It is a stock factory HTC One, nothing custom.

I don't think the Verizon model will have the correct radio frequencies to use T-Mo's LTE or HSPA+ network, hence you're stuck on Edge. If you're staying with T-Mo, I'd suggest selling your current One and buying a T-Mo specific HTC One.

This is pulled from Verizons website
Network: LTE, CDMA/1xEVDO Rev. A (800/1900 MHz)
Global Network: EDGE/GSM (850/900/1800/1900), HSPA/UMTS(1900/2100) aGPS capable for E911 emergency location, aGPS (assisted), sGPS (simultaneous), Standalone GPS, eCompass, GLONASS
T-mobile uses the 1900 Mhz base band and the HSPA as well. So i don't see the issue in that one.

From what I can tell, nobody uses the dual 1900/2100 to achieve 4G like TMO. The UMTS referred to on that phone is for worldwide use, not US. So while it may have the frequencies, it is not set up to use them like TMO. Your software and firmware are set up to work with Verizon and overseas, not with a competitor like TMO. TMO refers to theirs as HSPA+. However, it might work on the new "reframed" 1900 bands (which is called HSPA), but those are not very highly deployed. Unfortunately, I don't see LTE on that list of frequencies. The TMO LTE is really great. EDIT: I mean TMO LTE, which is also 1700/2100.
I suppose you could try unlocking it and flashing the TMO radio, but there is an entire thread on trying to unlock TMO frequencies (in that case on the developer version), and no one has figured it out yet.
I concur that your best bet would be to sell the phone and get a TMO model.

Yeah thats what im thinking. I need to contact and t-mobile rep and see if the re-farmed LTE here. Ill call and ask.

Alright so i called the rep and he said the area i am has been re-farmed to the 1900 range and i should be getting at least HSPA/3G but im not. Very odd issue

Verison use the CDMA, maybe that's why you can only use 2.5G network, just like some phones in China, they only have GSM in common

yes but this phone has 4g lte already in it which accepts the sim card. Also, i have seen other verizon htc ones with t-mobile and never had a issue. I fell i may have to use a custom rom.

What he is referring to is that what Verizon uses as "3G" is CDMA technology. So although they (T-Mobile and Verizon) may be on the same frequency they're using totally different technologies. Just because it has a sim card slot for a Verizon sim doesn't mean the device will be compatible with another carrier's sim. A custom ROM would not resolve this issue. Your best bet would be to sell this device and purchase one from T-Mobile. :fingers-crossed:

I know what the best way to go is but i am very curious as to what is really keeping it from going out of edge. baseband? Is the TMO and Verizon radios the same? these are things i need to know! >.<

My understanding is that the devices run on different systems for 3G and different LTE bands. You wont get more than GSM compatibility (GPRS, EDGE). Hopefully it is something that a software hack can fix but if you read around all the HTC One forums you will see no one has found it. Right now it is not possible.

My question is that HTC makes phones for all T mobile verison sprint the same, so I believe its just software problem that we cant use Tmobile 4g lte on Verizon unlocked phone. SO does anyone have any comment for that?

It is hardware not software that is the issue. The T-Mobile variant has different bands than the other variants including Verizon. T-Mobile is a GSM variant while Verizon is a CDMA variant. Here is a comparison of the specs for the variants.

CDMA and GSM technology requires the antenna to be done differently. If they are not programmed to use those signals. Nothing you can dox will change it short of putting a new antenna in.

Because you can only unlock GSM. Cdma uses the serial/esn number of the device.

Has there been any update on this? I called tmobile and they said it was simply because I couldn't put in the APN. So, there's no chance that rooting the phone and putting a tmobile rom on it would fix the problem and let me get more than edge speeds.

I myself have been wondering the answer to this. The device might seem the same but under the cover they are different. The actual daughter board which the camera, vibrating thing, volume rocker, power button are connected to are fairly different from each other. The CDMA variant is not compatible with the GSM variant. Not even by adding a CDMA daughter board to the GSM motherboard and vice versa, the are made quiet differently and will not be able to use GSM bands on a CDMA m7

1. Enable USB Debugging before flashing custom recovery.
2. Make a backup via recovery before granting apk's root permission, editing system files, or flashing a new Rom
