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
KitKat slo"g" slide

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
This is actually on old hack I used from the G1 forum. This is really useful if you are in an area where 4G or 3G is weak and you phone keeps switching back and forth to edge. Very annoying...
Install AnyCut from market
Open AnyCut and click NEW SHORTCUT
Click ACTIVITY
Scroll down to "Phone Info" and select that.
I renamed the shortcut "FORCE 4G" but you could name it anything.
Click OK
Now open the shortcut on your home screen, and scroll down to the bar that spans across the whole screen. This is the bar that controls all your network types listed here.
WCDMA preferred - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 3G is favored more.
GSM only - The GSM phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
WCDMA only - The GSM phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all. (FORCE 4G!)
GSM auto (PRL) - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more. This one is a bit confusing to me since PRL is associated mostly with CDMA technology and not GSM technology.
CDMA auto (PRL) - The CDMA phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more.
CDMA only - The CDMA phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
EvDo only - The CDMA phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.
GSM/CDMA auto (PRL) - Some phones are equipped with both GSM and CDMA capabilities. This setting appears to just have the phone attempt to stay connected to the data communication type that works the best. (MY FAVORITE ON G2X)
Unknown - If none of the above fit or the phone is acting weird as far as connecting to the carrier, you will see your preferred network type is set to this
Im sure this hack works on all android devices, less options will show for phones w/o that capability.
BetterCut will obviously also work and youll be able to customize an icon for the shortcut
Menu, settings, wireless and networks, mobile networks, network mode, wcdma only.
Won't that do the same thing without all the work?
*#*#4636#*#*
Phone information
Scroll down
Change WCDMA preferred to WCDMA Only
Same thing as well... If youre that desperate for "4g", however, if you lose 4g/3g you lose ALL SERVICE, I believe. I had played with these settings on my n1 last year. In the end, I found WCDMA preferred was the most reliable ;-)

He's talking about changing the hidden menu. There are two menus, if you change it in the non-hidden menu and not on the hidden menu, is different.
This should probably be moved to themes and apps or general. Nothing really developed here, no offense.

This isn't the hidden menu this is just the phone info menu that you can access with *#*#4636#*#*
Thanks! I skirt the edge of society and there are a few ROMs that I really like to use that don't have this option built-in. Bionix has it but CM7/Faux and others do not have the option available from the mobile networks menu. I'm sure it adds to radio life if you set it to stick with the highest signal since the phone won't be switching towers.
I have a post about this in the Q&A section, but have any of you experience the G2X using only 1X or CDMA data frequencies other than 4g?
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?
Sent from my Samsung Infuse 4G
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.

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!
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.
