About 4 months ago everyone was complaining about their text not going through for one person and the number kept saving as SIP: even when you entered a number. The SIP has stopped but I am still having issues with the message sending. It is only happening when I try to text my son who is on the same t-mobile plan as me. Has anyone figured out how to fix this? I have tried everything they suggest in troubleshoot.
