What is this in the communications settings?
3G Auto Mode
I believe that just means that your phone will use 3G if it is available. If 3G is not available or the option is switched to off, your phone will use 2G (EDGE) instead,
Set your Raphael to use 3G when available.
If you switch it off, it will use 2G network, even if 3G is available..
Ok guys, that makes sense, thank you.
I have another question along the same lines. After I turned the 3G auto mode ON, I see this "H" Appear every once in a while in the top bar. What is it?

That's 3G. The 'H' stands for 'HSDPA', so when it appears, it basically means you're using 3G instead of 2G (EDGE, which would appear as an 'E' instead of an 'H').
All icons, explained :
G --> GPRS, 2.5G, the slowest data connection
E --> EDGE, 2.75G, faster than GPRS
3G --> UMTS, much faster than EDGE
H --> HSDPA (may be HSUPA also..), the fastest data connection available on Raphael..

my data plan only use 3g (umts) and not 3.5g (hsdpa)... but my android always switch 3g to and looking for hsdpa back and forth and drain battery much faster
when umts change to hspda (icon change from 3g to H) then it use battery power.. in my case i use 3g (umts and not 3.5g or hspda ) data plan only... but android keep searching hspda signal and THIS is when battery used the most (the process) and EVEN when my area have 3.5g covered but because i use 3g only data plan... then the back and forth process (3g<->H) will kep coming and drain my battery fast
so... i look for any kind of workaround so our android keep stay in 3g (umts) and not drain any unnecessary battery power searching for hspda
maybe android "thinks" 3g/umts and 3.5/hspda as the same?? android categorize umts and hspda as one big fat 3G network
i wonder why newer os like android doesnt have this kind of feature in winmo there is an option :
disable hspa = so hspda disabled.. AKA 2G or UMTS only
enable hspa = enabled hspda, hspa, hsupa etc.. AKA 2G, UMTS and HSPDA
is there any tweak/program/widget/application that can enable 3g (umts) only?
i think it is settings>wireless networks> network mode> GSM
if not try *#*#4636#*#*
go to phone information and you can select preferred network type.
If this helps press thanks!
uhh i have tried that before (and choose wcdma only aka 3g only).. and no luck
reason like i sadi before android "thinks" 3g/umts and 3.5/hspda as the same, android categorize umts and hspda as one big fat 3G network...
so 3G in android is umts+hsdpa, while i want umts only
To get 3G UMTS only
Firstly make sure your device is rooted.
Download Root Explorer, if you don't have
Go to your system folder
Mount it as read and write (r/w)
Find Build.prop
Select and Hold it, and the options will appear
Select the open with button
Select the text editor
Scroll down to find ro.ril.hsxpa=1
Change the number to your desire network (0 or 5 = UMTS , 1 = HSDPA only, 2 = HSDPA & HSUPA)
For your case change it to 5 and it should be like this ro.ril.hsxpa=5
Save it
Then reboot
Now it should be running 3G instead of H
This worked for my HTC Desire HD
don't work for me.
In ro.ril.hsxpa=X, I have written x=0 and I'm still leaving a H

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?
Any way to disable (release) HSDPA/HSUPA like on Samsung ROMs via secret codes? Using 3G instead of HSDPA saves a hell of a lot of battery!
Even going down to 2G (GSM) suffices for exchange push sync or any mails for that matter.
Settings -> wireless and networks -> mobile networks -> network mode -> GSM only.
This way it will enable just 2g, as 4g is just a push up of 3g.
In short you can not just get 3g.
Either 2g or 4g.
What you get is
3G+HSDPA
OR
3G+(HSPA+)
The phone should automatically switch to 3G when idle to save power ... Mine does pretty quickly

mine doesnt switch automatically.. it does ONE TIME. but after reboot, it's just constant H. ( yes I do have separate H and 3g icons in my framework)

thanks all for replying!
i don't have the 4G model, the fastest network we have is 3G/HSDPA 21.6mbps
actually let me test how the phone battery holds up with "H" before i try switching to "2G"...
thanks again!
Hi All,
How do I make it so that my phone will not try and connect to the internet via 3G (the signal icon on the status bar has 3G written on it). Whenever my phone switches to 3G, internet doesnt work. this has been a problem for me here in Aus on multiple phones. While the icon says H, internet works awesome but the second it switches to 3G internet stops working until it switches back to H. It wouldnt be too bad, if it wasnt for the fact that the bloody thing switches back and forth every 5 seconds if Im in a good reception area, which is almost all the time.
Are you rooted/custom ROM? It sounds like it could be a poorly performing radio. Search for the radio/ril thread. You might find some answers there. You can switch your phone to 2G or 3G networks only, but the 3G option also includes H. So even if you left out the 2G you'd still suffer the same issues.
Hi..i owned a Lumia, but a bit frustrated when network keep switching between 3G and 2G.
i just want to stay only in 3G network..
have anyone test the field test by dialling "##3282"?
in there we can change 3G only.
But i didnt know it worked or not..
so far it doesnt change to 2G..
I too used the same test by dialing ##3282. In addition you have to toggle the ENS to OFF position (don't reboot).
When you choose 3G only. It exactly what it means, 3G only, not 4G (LTE) and NOT 2G either. So it will only connect to 3G and hence you are not getting 2G signal.
I wish there was a speed limit setting so we could avoid LTE rather than pure 3G only. Or choose 3G+2G together.
