Pls help....is there a way i can set my samsung galaxy grand duos to use 3g only....d edge network ere in nysc camp is dead but anytime it switches to 3g it works...

3g network only is available on my bb...thanx

Have you updated your OS to 4.2.2 Cos using 3g on 4.1 isn't a straight thing.

If you are on 4.2.2 follow this step

1. Click on setting

2. Click on "More networks"

3. Click on "Mobile networks"

4. Click on SIM 1 or SIM 2 depending on the one u want to use for browsing

5. Then select "WCDMA only"

6 Click "ok" for the next 2 pop-ups

That's all.
