Thanks, I remember I had to do that on my old phone. However, when I switched to GSM, it says connection failure. Not mxit, the phone

Sniff.
*EDIT* Let me be more specific:
Connection failure. Error code -7
When I go to my browser to try and download mxit:
packet data not available. check network services.
web: unable to perform operation
All of this worked up to here, with the Dual option.
Greetings,
Let me explain quick......
3G - UMTS = is like ADSL a permanent data connection between you and the cell tower. Even if you do not have your APN settings this data connection is still there. It needs this data connection for video. And it can handle both data and voice at the same time.
2G - GSM = more like a dial up internet. Your phone is there acting more like a MoDem. It needs to be told when to connect and how to connect. It can not handle data and voice at the same time and therefore puts the GPRS signal on hold when you are on a call. Unlike UMTS.
So what does this have to do with you?
Well it's a new phone...... You said you have received your settings, but...... Did you activate them? It's one thing to store the settings and another to activate them.
Goto your settings, connection settings, choose either Vlive, or internet. Then choose 'Activate default in all Apps'
Hope that helps, Please post back if worked or not.
Regards
Clefty.
