Why Are You Using Case Then?
Try this:

pawn Code:

if(dialogid == id)
{
if(response)
        {
                  format(string, sizeof(string), "* %s types in a number and brings their phone to their ear", GetName(playerid));
                  NearByMessage(playerid, 12.0, PURPLE, string);
                  ShowPlayerDialog(playerid, 8, DIALOG_STYLE_INPUT, "Phone", "Type in the number you wish to call:", "Call", "Cancel");
              }else{
                  format(string, sizeof(string), "* %s types in a number on their cellphone", GetName(playerid));
                  NearByMessage(playerid, 12.0, PURPLE, string);
                  ShowPlayerDialog(playerid, 9, DIALOG_STYLE_INPUT, "Phone", "Type in the number you wish to SMS:", "Proceed", "Cancel");
              }
        }
return 1;
}

if Pawn Crashes Remove Or Add One More Bracket Before Return.
