On the new nexus 4 i wanted to send a group message and this automatically changes the text message to a MMS message but he phone by default doesn’t have the required SMSC number in by default and doesn’t auto detect it so dialing *#*#4636#*#* brings up a troubleshooting/statistics menu page. Dial that and select Phone information and at the bottom you can enter the SMSC (Short Mail Service Center) number. I then clicked the refresh button and update this automatically put in the number required then i simply selected the back button and it was fixed!
