Hi. For some days ago i did following to get more battery time out of my Samsung Galaxy S2. 1. Dialscreen: * # * # 4636 # * # * 2. Made a change in "Set preferred network type", picked GSM auto (PRL). After that change I couldn't send messages in Handcent or the stock sms app. I found out that I needed to write the SMSC again. I wrote my SMSC number in the stock app, and it now works fine again. But I can't find a place to write the number in Handcent. I have tried to write the number in the same screen as I changed the GSM auto (PRL). It has no effect. Furthermore I have also tried to re-install Handcent, no effect. Can someone help me out?
