Wap and gprs in sgh-m610

Hello, I would like to ask on how to open again the wap and gprs settings on my samsung sgh-m610. I accidentally reset the wap settings in pressing #*7337#. I already try this , SET GPRS SGH_M610 send to 211 but its not working. Smart replied that the wap settings are already activated so i tried to send MMS but it appeared Configuration Error. Help me. I want to activate wap and gprs in my phone. Thank you. I will hope in your help.
