[Q] How to activate 2G/3G switch in INFUSE 4G (I997UCKD5)

please help.How to activate 2G/3G switch in INFUSE 4G (I997UCKD5).
I would like to switch my phone between EDGE and HSDPA+ speeds.

The Edge and Hsdpa+ speeds are the same on ATT lol
J/k
infuse 4g "a lot a screen real estate"

i just asked about switch, not for the ATT speed.
Somebody knows how to to activate this button?

There is NO switch like that, if you want only 2G then simply set the phone to "GSM only" and it will only get the slow EDGE speeds regardless of what area you are in.
If you do not set the phone for GSM only then the phone will automatically switch to 3G/4G speeds if those speeds are available in whatever area you are in.
Whenever you are in a 3G/4G area you will see a little icon in your notification bar if you have not set the phone up for GSM Only.

You're right... I tried to force GSM Only and failed.
Not sure why you would ever want to force WCDMA only. The phone will always prefer 3G over 2G.

I tried to force WCMA Only and failed.

The reason for doing that is if you are somewhere on the outer edge of a 3g/4g connection and it keeps jumping back and forth. All the signal jumping can kill a battery quicker.

When you go into the *#*#4636#*#* screen, select phone information and then hit menu. Select radio band and pick AUS. This locks my phone to 3g/4g.

How to Switch Samsung Infuse 4G i997 to 2G Edge Network. Turn off 3G/4G on Samsung In
Warning: This will work depending on where you’re at. If you’re in a good area with excellent coverage your phone may just stay with the H+ and not switch. Here we go.
Step 1) Dial *#*#4636#*#*
Step 2) Click Phone Information (at the top)
Step 3) Scroll down
Step 4) Click the grey/bluish menu and select GSM only. DON’T SELECT ANY OTHER ONES or you may roam on other carriers.
Why would you do this? You can save battery power by not using the H+ network.
_____________________________
To switch back to 3G or 4G
Step 1) To switch back follow steps 1-3 and then click GSM/WCDMA auto (PRL)

Tell me if this saves you battery -

It's been good to me but does it work for you?
I remember doing this for a few other phones with good results.
Now I'm doing it with my Sensation and it looks like its working... but I want more people to test it. Test battery drain and data speeds.
Anyways,
Type *#*#4636#*#* in dialer > Phone info > Change WCDMA to GSM auto (PRL) and that is it. You should see the battery drain less on stand by.
post results here... and a thanks would also be good.

if you only use 2g,you can set like that

GSM Auto (PRL): gives me 4G speeds
GSM only:gives me edge speeds
GSM Auto (PRL) isn't in the mobile network settings.
gsm auto prl will save the user a bit more power because it wont force the phone to continuasly hunt for a stronger signal

And just in case you guys want to play with some settings:
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.
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. (Maybe the Samsung Galaxy S will take advantage of this???)
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

So what's the downside? Edge speed more often? If there was no downside why wouldn't it be the default?

I find gsm auto gives slightly slower speeds in a speedtest than wcdma only... (only two settings I use) and that's it.

Data network modes - 3G or HSPA

My phone does something weird. When the data mode, shown beside the battery icon, is shown as 3G, no data transfer can be made until it is changed to 'H'. This gets very annoying.
The problem is that it stays at 3G until I want to do some data transfer, then it changes to 'H' which takes some time.
Anybody gets this as well? Is there anyway to prevent this?

H means hsdpa,which is High Speed Downlink Packet Access. It is 3.5G. And it is faster than 3G.

Same issue with o2 Pay Monthly, although it generally switches to H quite quickly when data access is required.

Correct me if I'm wrong. H means HSPA, which is 3.5G, and 3G is 3G in itself, and G is 2G? I thought 2G didn't allow data transmission? So isn't 'G', 3G?
I understand HSPA is supposed to be faster than 3G, but the problem is that 3G doesn't allow any data transmission.

"WCDMA"
H = HSPA = 3.5G
3G = 3G
"GSM"
E = EDGE = 2.5G
G = GPRS = 2G
All of them allow data access, or should do anyway.

No, "G" is not "3G". "G" means GPRS (General Packet Radio Service) and is an old standart to transfer data via GSM. It is, in fact, the slowest ond one of the oldest.
There are two networks, "2G" which is "G" or "E" (EDGE which is is a litlle bit faster than "GPRS" - and "3G" (now even "4G" ) which is a high spead network. "H" should mean "HSDPA" or "HSPA"
Oooops, to slow.
In addition: Via 3G you can do data connection and phone calls at the same time, this you can not do in 2G

Your phone will check to see what the best connection available is before downloading. The wait is down to your network provider's service and availability. And possibly your radio. It's not that it wont download on 3G. It will. It's just that 99 times out of 100 if 3G is available, so is HSDPA so it'll go for that one over 3G every time. Unless you are on my network provider. Then you'd get better consistent data transfer over a piece of wet string.
You could go into your phone setting and choose 'WCDMA only' if you generally have good coverage and want to cut the wait out?
Dial *#*#4636#*#*, from the resulting menu select 'Phone Information' then scroll to the bottom and change the drop-down menu to 'WCDMA only'.
Does that help?

Tip:
You can also do this without dialing a code:
Got to settings/wireless & network/Mobile network/Network mode
So you don't have to remember the code if you want to change settings

I tried this. For now it seems that it is stuck at HSPA now! Thanks! Am I right to assume that under WCDMA only mode, I either get HSPA data or no data at all? The phone will not go to 3G or 2G right? (there's no 2.5G here)
Thanks to the others who clarified the 2G,3G,3.5G terms. I understand it more clearly now!

WCDMA only means you will only have HSPA and 3G connections. You will not have, as you wrote, 2G. 2.5G means EDGE which is still a 2G connection but a little bit faster than GPRS, and right, you will not have that.

HSPA includes HSDPA and HSUPA. I really don't know the difference between them.

HSPA is faster than HSDPA, and HSUPA is the standart for uploads. You should visit Wikipedia for detailed information.

HTC one S EDGE speeds

Herro! first time poster, long time lurker! i searched around, and couldn't really find a similar problem.
I got an HTC one S from Fido, unlocked it, and i've been trying to use it on Bell. I tried several different APN's until one finally worked...but only EDGE speeds! It's also draining my battery extremely quickly. also, when i put my bell sim card inside, preferred network mode changes to WCDMA instead of HSPA (like on the fido sim).
why is this happening? i was told a fido phone would work on bell with no problem. why no 4g speeds?
thank you and i appreciate the responses in advance

HSPA uses WCDMA, so that makes no sense... Under preferred network you should have WCDMA only, 2G only, or WCDMA preferred if I recall correctly as I'm not on stock HTC rom atm so can't check. Are you getting an "E" signal indicator or are you just getting a slow connection? What does it say under About phone>Status>Mobile Network Type?

Set it to Auto mode in the network settings.

yeah, all the tech support i've talked to said it makes no sense either . i get the same outcome whether i put it on WCDMA only or GSM/WCDMA auto. when i do the speed test, it always comes out under 1 mb/s. it actually has the 4G symbol up, but the speed isn't there.
mhmm, it switches between UMTS and HSDPA.

If you have UMTS and HSPDA under status its working, and those are also what connection you're really on. If you always have a 4g icon on status bar it seems like your carrier has modded the software like T-Mobile USA does so it always shows 4g no matter what's up in the real world.
Maybe you're not in a good location and that's why you get slow data. Also I have no idea how Canadian carriers work but I'd guess if you're connected to a 850 MHz cell you'll get worse speeds than on a 1700/1900 one. Don't you guys have insane data caps everywhere, perhaps you hit yours when speedtesting?

did you try a new sim from bell

Is there any possible way to force a particular network band with the one xl?

i know you could do it with the galaxy s3, but it seems like it cant be done with this phone.
the secret menu has practically nothing in it, and only WCDMA preffered, LTE only, etc
i want to be able to force a particular band, could this be done by editing the build prop? i want to try and force 900mhz
can it be done, or am i searching for hours on the internet for nothing?

Sounds like you have a CDMA phone. "No SIM Card". Sprint or Verizon ????
If this is the case, then you are looking in vain.
AT&T HTC OneX
Android 4.1.1
ViperXL 3.2.3

NAH i have an australian htc one xl. i am on a carrier (not particularly the fastest) but i have unlimited data and wanted to see if i could increase my download speeds by locking onto a particular band lol

Are you talking about selecting something like this in the phone info "secret" menu?

You're confusing WCDMA with CDMA.
WCDMA refers to the HSPA (3G) radio on this device, and not to be confused with the CDMA network used by Verizon and Sprint.

Is this what you are talking about?

[2G/3G/3.5G] Preferred Network Types Explained & How To Change It Easily
I'm noticing most of us are on the AT&T Network, yet there are those that do not want or need 3G/3.5G and want to use 2G or have another carrier so they cant take advantage of the speeds because they are on a Network such as T-Mobile.
Obviously someone using primarily or mainly 2G will see significantly more battery life.
This is good for someone that rarely uses data service or goes online using WIFI for the most part.
To change or edit your Preferred Network type go to your Phone app
then enter the following: *#*#4636#*#*
>Phone Information
>Set Preferred Network Type
Now you are able to change and edit the way your phone looks for and uses the Network you are currently on.
The Terms are explained below:
Preferred Network Types change the type of frequency the phone searches for.
Android is used on several devices that can gain access to different cell carriers.
For simplicity, there are two main types of cell carriers, GSM and CDMA.
The following popular data communication technology is associated with each cell carrier type:
GSM = GPRS (2g), EDGE(2g), UMTS(3g), WCDMA(3g), HSDPA(3g) {Cell Carrier examples: AT&T and T-Mobile}
CDMA = CDMA*(2/3g) EV-DO(3g) WiMax(3/4g) {Cell Carrier examples: Verizon and Sprint}
Now that the general stuff is out of the way, here's my take on the Preferred Network types:
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.
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.
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
When using the 'only' options you should still be able to make calls.
To put things into perspective, The Nexus One is set to WCDMA preferred as default and the Droid Incredible is set to CDMA auto (PRL).
