I'm from India using BSNL and here 2G is extremely slow and 4G is not yet out in my area . I want to have '3G only' option for data, to lock my network on 3G network.
Before amber update in my Lumia 820, I was able to use 3G only data using the ##3282 field test method.But now it isn't working after the amber update..neither in the GDR3 Preview. There had been apps like "3G switch" in the android which I was using in my previous phones. Any help in locking to "3G only" mode will be greatly appreciated.

Did you change the Highest Connection Speed option in settings>cellular. And you should also select the correct carrier. FOr example I manually selected Vodafone 2G,3G.
Which carrier are you using right now?

It may be carrier blocked, Have you tried
Choose ... Settings
Change network selection to 3g..
Restart the phone..
works on my 521 gdr2/amber

Sound like it blocked then. because when you put ##3282# into the dialer, it should take you into field mode test automatically.
Thanks Pankaj981 for clarifying that field mode is blocked on India Rom.

Has to be done at OEM level, developers would not have access to what is needed..
You could always flash your phone with an Europe Rom that has the option enabled or has option for highest connection speed listed under Cellular Connection.

Oh,issit? U mean to say Europe rom has 3G only option?
Not highest speed. That's there in Indian rom too. Even though i set 3G,it automatically switches back to 2G as 3G signals r weak in my place. My android phone before had three opions viz, 2G, 3G and 2G/3G.
I want that second one 3G only. Is there such an option in Europe roms, if so im gonna flash that.

Same problem for me also BSNL and NL 620.
Solved: Downgraded Amber and GDR2 Update to older version with the help of Nokia Software Updater 4.1.0
Now field test works and selecting 4G in field test gives signal (earlier only 3G)
