i recently bought galaxy s2 at&t phone. im able to use only 3g on it. how do i use 2g/gsm? do i have to contact my service provider or just edit settings on my phone beacuse i dont see any option on it regarding choosing between 3g or 2g?

go to network settings in galaxy s2 set network mode you will find WCDMA and so on their you can change network mode.

Opt out of WCDMS/GSM OR WCDMA mode and and Select GSM in wireless and network settings

i tried doing that but the problem is that i dont have the option of choosing between 3g and 2g. in the wireless settings, the other phones have 5 options:

1) use packet data
2) data roaming
3) access point names
4) network operators
5) and some other option of choosing network (gsm/3g)

this is where the other people choose their respective networks.

my phone doesnt have the last feature.

any answers for this problem.....

choose gsm here from option 5.
