Pocket PC FAQ Wiki > Smartphone Issues
One of the issues you may experience is that you cannot dial contacts that begin with a #. For example if you have a contact called T-Mobile? and entered #225# for your balance or #646# for the minutes.
For Samsung Smartphones you can switch from 3G to 2G by performing:
1. Power Off then Power On
2. Type *#1546792*#
3. Select 3
4. Select Network Mode to GSM instead of Auto
This will improve the battery life significantly (about double).
