Selecting 3G band - HTC Sensation

Hi everyone,
I have a strange problem with my Sensation. I'm not sure what spec it is.
Here is the issue.
When I go into *#*#4636#*#* -> Phone information -> Menu -> Select band
I have 3 options: EURO, AUTOMATIC (DEFAULT), USA
My provider uses 2100Mhz as 3G frequency. When I leave the setting at default i get very slow speed, less than 1Mbps if I switch it to EURO I get 6.5Mbps. Leaving it in EURO setting also kills all the 2G frequency except 900Mhz, so roaming in the USA was not possible. I had to switch the phone to USA, then it's no problem.
My question: Why can't I change the 3G band in the normal menu? Is there a way to do this? Or do I always have to go to the special menu?
Why leaving it at AUTOMATIC gets my so slow speed?
Hope someone can help.
Thanks!

Regedit hack to force UMTS/HSDPA

hey guys
i know i've seen this thread somewhere here before but i can't seem to find it... can someone give instructions on how to force my Treo 750 to only use the UMTS/HSPDA band? i ask because if i ever roam onto an EDGE or GPRS band my data charges are extremely expensive (3 Australia).
thanks!!
forgot to add that i'm using the ATT WM6 ROM... is that as simple as just going into the band selection and selecting UMTS in the network type? What about the GSM/UMTS band? does that need to change?
Menu (right soft key)-> Pref-> Phone Settings-> Band Selection Tab-> Choose your settings.

Turn off 3g on the fly

So far my Touch Pro has been great, but the battery life has been a bit lacking.
I'm wondering if there is a program which can turn on and off 3G easily and quickly, but without rebooting the phone, so you can turn on 3G when you want to surf the web for 10-15 minutes, but turn it off for the majority of the day to conserve battery.
Any ideas?
Regards
If your ROM has Band Selection enabled, go to Settings -> Phone -> Band and you can choose GSM (2G) or UMTS (3G)
What do I change? Under Select Network Type there's Auto, GSM, or WCDMA
or under Select your GSM/UTMS band there's Auto, GSM(900+1800)+UMTS(2100), GSM(1900+850)+UTMS(1900+850) or UTMS(2100+800)
At the moment both are on auto. Which do I want for just GSM and which would I want for 3G when I want it on?
Thanks for the reply
you would want Select Network Type to be set to GSM for GSM/EDGE only, and WCDMA for UMTS/HSDPA/HSUPA.
(the other setting is to choose which frequencies you're using)
It would appear that there's exactly the app I was looking for which turns 3G on and off. It's here

lock your infuse to cdma

Dial *#*#4636#*#* go into phone information scroll down and choose wcdma only and your done default is GSM/WCDMA auto (PRL)

please excuse my ignorance, but what would be the purpose of this?
so that it dosent jump around from 3g 2g if its auto and your not using data it automatically defaults to 2g i think to save battery then switches to 3g oir hsdpa 3.5g or what att calls 4g on demand this keeps it locked on wcdma or 4g to my knowledge

seems like it reverts back to auto after a reboot
This makes the phone work on Verizon, right?

See that's what I thought too. ATT = GSM, Verizon/Sprint = CDMA.

Mine goes back to auto as soon as I back out of the menu. Am I doing something wrong by using the back button?
wouldn't this, by locking it, render the phone useless when traveling out of area that support that network?

Mine does the same thing. did you figure out how to do it? I have been trying but I couldn't do it
I found this here in the forum someone posted and it worked for me thanks for him.

Here's an alternate method I puzzled out (and then afterward discovered it was already posted in thread 751237. It's a bit faster and has the advantage of surviving flight mode; still gets reset upon restart.
Dial *#*#2263#*#* (mnemonic: *#*#BAND#*#*).
This brings up the Band selection menu which you can also access from the above method by dialing *#*#197328640#*#* then going into DEBUG SCREEN > PHONE CONTROL > NETWORK CONTROL.
Select [3] GSM BAND
Select [1] GSM ALL
Select "Select GSM All Bands"
Menu key > END
To switch back, go to *#*#2263#*#* and select [1] AUTOMATIC > Select GSM &WCDMA All Bands > Menu key > END.
Something else I'm trying out is switching the acquisition order so when it is in "dual" mode, it'll try GSM first. Even so, it will still switch to 3g if there's enough signal. Seems to help keep it on 2G though, when it would otherwise cling to a faint 3g signal with 0-1 bars.
To do that, go into the NETWORK CONTROL menu (see above) then
Select [4] AQUISITION ORDER (yes they misspelled it)
Select [2] GSM->UMTS
Select "Select ACQ_ORDER_GSM_FIRST" (at least they abbreviated it correctly)
Menu key > END
This option does not get reset upon phone restart.

I did this and now my sms or text messaging don't work help
I had this happen too, but I didn't use the above method. Don't know what happened, but when I checked message settings, I had no number under "Message Center" did a quick google search and found an ATT number "+13123149810"...now it works again.
Did u call the number
Never mind i fixed it.but now in my network type it says umts is that faster then hsdpa and are there any other number sequences i can use to tweak my phone
I'm getting RAT restricted, which I got on my Vibrant but never my Captivate...
How can I change to show the different bands?

wcdma and cdma have nothing to do with each other. wcdma is also known as umts, the base part of 3g (and 4g when hspa+). hspa is a protocol that runs on top of this cell technology providing higher data speeds. gprs (known as edge, and some times called gsm) is 2g. you can turn one or another off so the phone does not seek and connect to both services, which could save battery life. even though ive yet to see my phone find less than 3g/4g in houston, i still dont turn it off, just in case.

[Q] Can't change band frequency. Why?

I'm from Brazil and 3G signal from my carrier is really poor at my home.
So my phone keeps switching between frequencys every time and it causes instability on my signal.
I'd like to change my band to use only 850Mhz like I did in my old Samsung device in order to solve my problem, but when I type *#*#4636*#*# and go to Phone Info > Menu Button > Radio Band Selection there's no options to pick. Why? How to solve this?
Use an application called phone testing in the playstrore

[Q]N5 on Straight Talk LTE

I'm on Straight Talk with an AT&T SIM card. I have a few questions
1) How do I know if I can get LTE speeds? Anything that tells me if it is working, but not available in my area? I'm in between cities which have LTE, but I'm in the 4G area. APN settings are correct (I believe, although MMS doesn't work) and my preferred network type is set to LTE/GSM/CDMA auto (PRL).
2) In the Phone Info (*#*#4636#*#*) options, I press "Select Radio Band" and android.phone crashes. Doing research I found it's an issue since 4.2 or so. I'm wondering if I can force a 850mhz frequency so I can get better signal inside buildings (if this makes sense, I don't fully understand cell frequency, etc). I went to a restaurant the other day and couldn't get any bars at all.
Any help appreciated. Thanks.
