On my GS3 I used to be able to type in *#*#4693#*#* and it would open a menu where I could toggle my data from 2g to 3g to LTE or any other option. I think it was called a service menu.
Now on my GN2 I can't get that menu. I have seen a thread that lists all the secret codes but I can't find the one that allows me to toggle from 2g to 3g and vice versa. I don't want to use an app to do this.
Does anybody know the code?
You should just be able to do it in the mobile data menu

No, I can't. I know you can switch from LTE to 3G or turn off data. I can switch from GSM only to LTE/GSM/WCDMA or WCDMA only.
That's not what I'm looking for, I'm looking to switch from 2G to 3G and back. I used to be able to do it in the INFO service menu.

When I connect to internet depending on the location sometimes I get the G icon sometimes the H icon.
Is it possible to set it only to connect on H (even if reception is bad, 1 bar only, rather than G with 3-4 bars reception)
Is there an App for it? than can let you choose what you wanna connect to?
I know in my nokia n95 i could go to networking and choose what i wanted but i cant seem to find that on the galaxy s.
any help would be great
thanks
LOL...
G - GPRS
H - HSDPA+ (faster than 3G)
You can't change it, It depends on your signal strength and location.

constant HSDPA+ would also kill your battery too..i would image ye?
Only as much as what constant 3G uses.
im sure its possible because here is how to do it on the Omnia HD, its just a hidden menu setting
http://forums.samsungi8910omnia.com...ncrease-web-browsing-speed-when-using-3g.html
we have the same menu on the Galaxy S, so if someone can just figure out how to get to this part then you can do it
That is to increase the speed of the 3G. You can only see results if your using 3G,not sure it will increase the speed of the HSDPA. Also this wont allow you to get more of the signal or allow you to use just 3g or hsdpa for internet, again its down to network signal and location.

You could do *#*#4636#*#* in the phone app and change CDMA/GSM Auto to WCDMA or WCDMA preferred for 3G only, but you will have no service if you leave 3G coverage since it will not revert to standard GSM.

That method didn't work for me when I tried it; each time I re-entered the menu, the settings had reverted to whatever was chosen in Menu -> Settings -> Wireless & Network -> Mobile Networks... either GSM Only or GSM/CDMA auto (PRL) depending on whether the 2G only box was checked.
To get 3G only, enter ServiceMode:
*#*#197328640#*#* -> Debug Screen -> Phone Control -> Network Control -> Band Selection
Choose WCDMA BAND for 3G only.

Yes thank you for this informaion. I was able to get to the service mode but was not able to change the band selection.
I receive the error: RAT Selection Option is Restricted !
theres probably a way to shortcut the screen with anycut but ive given up trying
I cab only get edge at work but it does actualy give me about 100 kbs
I've noticed in the menu options, there is an option to keep the phone in 2G mode only. On the other hand, is there any way to keep the phone in 3G / 3.5 / 4G mode? Any software that can do this?

The phone will only switch to 2G if faster speeds are not available. The 2G mode option allows you to prevent the phone from switching to faster (and more battery consuming) data connections....
From the dialer, you can type in *#*#4636#*#* to bring up some "secret" settings. From there you can configure your phone to only use 3G.

How about if I don't want 2G at all and want it to stay 3G only, even if there is no signal? I remember this option on the SGS 2..

You do what chrono just said and the hidden menu let's you force 3g only. *#*#4636#*#* on the dial pad.

Go into phone info. From there if you scroll down a bit you will see a text that says something like "GSM/CDMA auto". Press that and you should get a drop down menu. Change the setting to "CDMA only". That should work.

Not sure how that disables 2G (1xRTT). Unless I'm mistaken, both 1xRTT (2G) and EVDO (3G) run on top of CDMA.
Also, you can get to this from settings->wireless & networks->More...->Mobile Networks->Network Mode
There you can select LTE/CDMA or CDMA.
And it always sticks
Wondering if there is a way in the network settings to force 2G ONLY or 4G?
WDCMA Preferred
GSM Only
Something like that?
Only way is dialing *#*#4636#*#*
And selecting it there.

This app is much faster than dialing:

I use it all the time to quickly change from HSPA to EDGE.
You're welcome.
How do you set 3G data only, dont want to use LTE to safe battery life.

In mobile networks switch network mode to wcdma only.
Edit: could be hspa only, depends on your model.
4g is not lte by the way. If youre on lte it says lte not 4g
Sent from my LT28at using xda premium
lte is 4g on most roms that I have seen. Although I never used the lt28at just the lt28i and lt28h where hsdpa+ is called h+ and lte is called 4g.
There should be a toggle that you can download that will be able to click 2g 3g or 4g. I know on miui there is a toggle for that.
If you're using a Lt28at like me, you can't toggle anything but LTE. SInce the boot loader is locked it will give you the option to pick a different frequency, but will automatically revert back to LTE. Sucks.
The version i have only give me LTE data, or no data at all.
It is locked to rogers.
Can it be changed so i can use 3G only?

No. Your boot loader is most likely locked also. You can only choose LTE. The only other option is to find the APN setting for 3G and enter it in your mobile networks and choose it. It will only use 3G but your phone will always search for LTE by default. You will save some battery by going that route. I don't know what the 3G apn for Rogers would be, however or if there is one. AT&T has a separate apn for LTE and 3G. Maybe someone else here knows more...
Yea, i just found out this can not be unlock... thinking android can be unlock easily since my last 2 phones can do it.
I will find the 3g apn.
Hopefully someone can find a way to unlock it and use other rom..
Is there any way to force the phone into LTE only mode?
There are two towers near my house, but only one has LTE. My phone keeps switching back and forth from LTE to CDMA, but when it's on LTE it works great. I just want a way to keep my phone from using CDMA.
Dial 3845#*970#, scroll down to iot hidden menu, system selection, network mode, lte only. However you have any CDMA service at all so you won't be able to call or text.

Hey,
The software version on my phone was updated and now I can't see the iot hidden menu. Is there a workaround?
Thanks
