from previous http://support.t-mobile.com/message/211986#211986 Go to: Settings -> About phone -> Status -> My phone number If your phone number read from the SIMM card is "Unknown", this option will not show-up. ---------------------------------------------------------------------------------------------------------------------------------------- It currently shows "Unknown" for My phone number under status. How do I update the my phone number field to show my actual phone number rather than show unknown? Im hoping by fixing that that will fix my issue with missing the group messaging option
