How can I set Android Galaxy Ace to only use 3G network? I am having a little bit of a hard time with my new android phone for the reason that it doesnt always connect to certain services (such as Angry Words, or Whatsapp). Sometimes I get the message "unable to connect", when I am using a fairly good network provider and strong enough wifi when at the office.

What I've noticed is that the 3G sign keeps changing to H every now and then. I dont know if that is the issue. Anyway, how can I make the phone only use the high-speed 3G service and why is that that even with strong wifi signal it is giving me a hard time?

Note: Wifi is turned off all the time I am not at home or at the office.
I was in trouble getting my 3G to work, and I did these steps, that solved my problem:


Go to the dialer and type *#*#4636#*#*
Tap "Phone info"
Scroll down, you will see GSM selected;
Open the list and select WCDMA only;
Turn the radio off and turn it on again (there's a button for that on the screen)
Press Home Button, not back button


If you still can't get 3G, reboot your phone and that's it ;)

Enjoy! :)
