How can I turn off 3G and use just 2G? SOLVED

Hey everyone,
I've had my Galaxy a few days now and I noticed there's no obvious option to turn off 3G like there was on my old Topaz.
Does anyone know if it's possible to turn off 3G (not data connection, I still want to use 2G) to save battery life.

Go to settings > wireless and networks > mobile networks > use only 2g. The option is there.

Erm, that option isn't there, all it says in mobile networks is:
Data Roaming
Access Point Names
Network Mode (this is only GSM/WCDMA switching)
Network Operator
I bought my phone as handset only so there's no branding and is rooted (option wasn't there before rooting either).
Can anyone help? Is there an app that can help?

My options changed when I upgraded to the newest firmware available in Australia. GSM is 2G and WSDM is 3G.

Go in mobile networks, access point names and create a new apn with 3g settings. Look on the internet for your carrier settings

I would like my phone to be connected to 3g all the time in order to save battery... Is there any way to do this? Changing to gsm, CDMA in network settings still gives me hspa.

HSPA is still 3G. If you want you can select to use GSM only and you will only get EDGE connectivity.
Dial *#*#4636#*#* , go to phone information, and there's a dropdown which by default says WCDMA preferred. Switch that to whatever else you need. Also, remember that this setting does not stick after reboot so you need to reset it to your preference each time after you reboot your phone.

Misread, sorry.

[Q] No 3G on unlocked Sprint HTC one M8 in Spain

I have a HTC One M8 sprint that i bought on Ebay, i have no problem to make and receive calls after i unlocked it but there is no mobile internet.
My APN Settings is correct, however i only have the option of bearer: LTE or eHRPD or Unspecified
When i search for networks on my normal phone i always get two options:
Movistar 2G
Movistar 3G
Vodafone 2G
Vodafone 3G
and the other networks here.
On the HTC that i sim unlocked i only get:
Movistar
Vodafone
Orange
There is no indication on if it is 2G or 3G.
*#*#4636#*#*
Have set it at GSM Auto PRL and restarted the phone, i have also tried all other network types without success.
Under Phone Info i get Current Network Movistar
GPRS Disconnected (Cant seem to activate that)
GSM: In Service
Network Type: Unknown
I have tried different radios, but no one has worked and they all end up with the phone entering a loop where it restarts and cant recognice the SIM card.
Mobile Network Settings:
Network mode: GSM/UMTS Only
Allow GSM Data: Ticked the box
Is there anyone who has been in the same situation and who has found a solution?
I have seen a number of posts where people say that they cant get data but calls is working, but the only resolution that people has offered is to set the GSM Auto PRL and restart the phone, that has not worked for me.
Very happy for any help that you can give!
Thanks

I am having same issue
Any solutions yet ?

Have you tried setting a GSM band from the top menu of *#*#4636#*#*?

You mean by changing bro wcdma prefered or gsm pro ?
Yes everything

Use QPST tool and allow all 3G networks to work. It unlocks all 3G networks. You are not getting UMTS signal because Sprint by default has unlocked only US 3G band (I think 1800). Hence, you need to unlock all 3G networks

add correct APN settings for your carrier in Settings -> Mobile data -> Access point names -> menu -> New APN

I did that but still no signal in 3g and 4g.

Go to dialer, type *#*#4636#*#*, go to set preferred network type and make sure you select an option that includes CDMA, LTE and Evdo
