How to set your Titan to EDGE/2G only mode

htc titan to edge/2g

In the dialer enter ##3282#. This will open a diagnostic menu. Select ... > settings and you will see an option for network type. This setting gets reset if the phone is restarted.

i have tried but after setting it to 2g or gsm but when i call on from the phone niether i can hear nor the other side can here. also when i recieve the call both side cannot here.

can anybody let me know why this is happening. Am i doing wrong setting . Please let me have detail procedure for the same.

In NOkia Lumia 800 in the cellular setting they have the option to set at 3g when found. you can auto set this.
