Turning Off UMTS for us S.Floridians T-Mobile

As T-Mobile rolls out their 3G service, it appears 3G HTC phones automatically lock onto the 3G signal (UMTS) which T-Mobile has politely firewalled until they rollout the plans???? So if you have a Kaiser or Hermes in S.Florida you currently have no data access on Edge as the phone defaults to the firewalled UMTS.
SO the question is any of the tech geniuses here know how to switch off UMTS, changing the bands does not help as UMTS, and GSM bands match up (on hermes), switching to a NON- T-mobile frequency also switches the GSM to Non-T-Mobile.
???? Beware if this happened in S.Florida as the network enlarges, you too could be next.!!

By no means am I an expert. But I do know a lot of the cooked roms have an option in the commanager which allows us to turn on/off 3G

Again, I'm no genius at this(That statement makes my reply a little bit more flame retardant) But I hope that helps. I can't wait until they hit the 3G switch here in Chicago.

Wish it was that simple!
Unfortunately it appears that this may disable the 3G data connection but not the radio. Hence the network still sees a 3G phone and treats it as such. The only way to get around the problem is to actually de-activate UMTS so the network sees an Edge only capable phone. Thanks for the help though!

I'm surprised your phone logs on to the T-Mobile UMTS network. It uses the 2100/1700 MHz AWS band, which no Windows Mobile device supports yet. Are you sure you're logging on to T-Mobile, instead of AT&T Mobility? My phone does that from time to time when reacquiring a signal.
Try forcing your phone to connect to T-Mobile instead of using automatic network selection.

Dumb question, but what if it is detecting the 2100mhz half of the UMTs connection.

I've heard (and I'm pretty sure) that the 2100MHz AWS band that T-Mobile won is different than the standard 2100MHz used worldwide. Plus, I don't think the radio will be able to register on the network anyway if it only has a one-sided conversation with the tower...

Yeah, the TMobile uses a combo of 2100mhz and 1700 mhz, while Europe is 2100/1900.
Chances are its picking up the AT&T UMTS network, but you can't roam on it. Are you using a stock ROM? If you're not, go under settings > phone > band (most cooked ones will have this), and change it to strictly GSM. That will lock it to GSM until you change it back.
If you are on a stock ROM, there are various tweaks you can get, I know HermesTweak will let you (yes its old, I stick to cooked ones so I dont know any other standalone ones). Or hell, you could even install Schap's 6 button comm manager as it has the 3g option on there.

T-Mobile Rhodium spotted on FCC as NM8RHOD210

So the previous filling which was found in early april (filed on Feb 11, 2009) and was though to be t-mobile's rhodium although the test report showed it was sporting At&t's 3G bands, 1900 and 850MHz, is now outlived by a newer filing.
Issue date April 02, 2009 FCC ID NM8RHOD210 with t-mobile's 3G 1900mhz and 1700mhz

You guys think since the At&t banded rhodium was filed earlier that it would be released before t-mobile's RHOD210?

Now I just need a price & release date so I know how much longer I'll be keepng my original Wing

wow, your still on a wing!? I've got a classmate thats still using it with the original shipped rom from when it first came out! I hope you've atleast updated yours.

I thought T-Mobile 3G freq. is 1700/2100 AWS... Where's the 2100 freq. in the FCC docs? I couldn't find it...
OPPS... nevermind. I just checked the FCC docs for the htc dream (aka G1) and they only list the 1700 AWS downlink freq. also. So... I wonder what the 1900 WCDMA band is for? It's BAND I, so does that mean Europe or possibly for AT&T also?! I thought Band II was 1900...

Band I = 1900Mhz uplink and 2100Mhz downlink but it's preferred to as UMTS 2100Mhz.

Thanks for clearing that up! The Wiki definitions weren't that clear to me...

fone_fantatic, I was wondering that same thing, in regards to the dates of the FCC filings. Everything is of course rumors at this point, but it's been said that T-Mobile will be selling it first. However, as you said, the first model to pass FCC was clearly not T-Mo, contrary to original postings. Thing is, that doesn't confirm or deny anything either. T-Mobile could still have rights to selling the phone first. We do at least have a rumored (there's that word again) date on T-Mobile, but I haven't heard a word about an at&t release, though the TP2 is clearly listed for them in that HTC roadmap layout.

How come I don't get the H for hspa+ when I'm running sense?

Why don't I get the H on the notifications bar when I'm running sense on my g2..its usually EDGE or 3g...when I switch to stock it shows the H
sent from t-mobile g2 using HTC sense

Tmobile wanted to give the impression of nearly 4G almost anywhere and made it so HSDPA which is 3G would appear as H AND HSPA+ would appear as H so users would believe they were getting the full HSPA experience.

So 3g in the UK is the H...so by having the 3g on the notification bar means I'm running there "4g"..or hspa+ here in the US...Mmmm...

the Sense ROM shows the correct network designation, whereas the T-Mobile (stock) ROM does not.
There are several 'levels' of 3G (based on theoretical speeds):
UMTS - just basic 3G. Slightly faster than EDGE, but not much
HSDPA - faster than UMTS. HSDPA is to UMTS what EDGE is to GPRS, essentially.
HSUPA - Like HSDPA, but with enhanced upload speeds
HSPA - faster again
HSPA+ - this is what T-Mobile is calling '4G'. It's not *technically* 4G, but it delivers what are generally accepted as '4G speeds' (basically the same speeds as Sprint's WiMAX and AT&T/Verizon's LTE will have).
The T-Mobile ROM shows an 'H' anytime you're using 3G or '4G' - basically, if you're not using EDGE, T-Mobile shows that you're using 'H' (which is what they call 4G).
The Sense ROM doesn't fall victim to this, and thus correctly identifies UMTS/HSPA as '3G' and only shows the 'H' when you're on an HSPA+ tower (the only time you'll see true 4G speeds).
There's nothing wrong with your phone.

im running virtuous and im getting 3g and H ...weird but im getting decent speeds

Thank you..I did not know this..I'm loving sense more now that I know that it will always show you the true speeds...

[Q] AT&T How do i tell if i'm on LTE or HSPA?

This is what my phone looks like when using data (i'm on at&t):

It just has a 4G logo, but i saw a video of someone else that had a 4G logo with LTE over it. Am i on lte? The closest lte city (on the at&t coverage map) is out of state for me, so i was unsure if i was on lte or not. The best speeds i've seen so far are 9500kbps down / 1200kbps up.
The reason i'm asking is because i think i found a way to disable lte and force hspa+ connection. I created a new APN and entered the details i found online. When i switch to this alternate APN, the 4G logo is the same, but my speeds are different (5000 kbps down instead of a consistent 9000+). When i switch back to the default APN my speed goes back up to 9000+.
Will using this alternate APN which yields slower data speed save battery for me?

That's HSPA, on your screen shot.

Thought so. Will using the other APN save battery then? since it yields slower speeds?

This is the logo you'll see if you're on AT&T's LTE

Dont think it will save anything as lte us still enabled.
I am not in an lte area and get good battery. From 1 to 2days depending on use and whether I turn off data at night.

HSPA+ vs LTE

I've had nothing but terrible LTE reception in my area, despite T-Mobile's coverage map showing I'm in the area. So I decided to do a little test.
I woke up late at night and ran Speed Test on my phone to check my speed. I found that I got the best download speeds late at night when I had my S3, likely due to less traffic. Here are my results:
LTE: 3.80 Mbps Down, 1.31 Mbps Up
HSPA+: 12.69 Mbps Down, 1.7 Mbps Up
Crazy isn't it? Good thing I'm on Wifi almost everywhere I go otherwise that would drive me nuts. Results are even worse during the day.

I get pretty amazing LTE service in most parts of KC i usually get between 25-30Mbps down and about 15Mbps up or so. When I'm at home though my service is lousy with about 5Mbps down and 1Mbps up so for me it just depends where I'm at.

Before the Coverage map used to say because lte is still fairly new it's not a very good exactment on the coverage side or something on those lines. Anyway just because it says excellent or very strong doesn't mean LTE it just means it's a great coverage whether it be H or H+ or LTE. But it doesn't specify if that exact location is LTE. At my address it says excellent but it is only with H+ however.

So why don't you set it to only wcdma/gsm?
That's what I did cuz lte where I'm at is ridiculously slow.

Here in Augusta, i'm rarely on LTE, Usually if a get a good signal it's only 4G (HSPA+)
Even when i was on the (V word) network. My network in this area, with a tower 2 miles away i only got 15mbps dn and 5mbps up

HSPA+ is 12mps maybe on a good day.

I'm getting pretty crappy LTE signal too indoors, works fine outside but it worked in my office on my Note 1 as well as outside.
Sent from my SM-N900T using xda app-developers app

same thing here in MN. coverage area says "excellent" but lte is horribly inconsistent and unusable for anything that involves downloading. this applies whether i'm indoors or out, rural or high-density urban area. HSPA+ gives me a consistent 2meg download speed on the play store, and that applies to browser downloads as well, so until they get their QoS issues resolved, i willl likely keep it to WCDMA/GSM.
