My wife has a Galaxy S6 (T-Mobile) and I have a Galaxy S6 Edge (T-Mobile). For some reason when she sends me texts I don't get a notification and I can't see her message when I open the SMS tab of Join. I am wondering if this has something to do with Advanced Messaging: https://support.t-mobile.com/docs/DOC-23589 I've tried following the steps above but I still can't get her incoming SMS' to notify me or show in the SMS tab. Any one else have a similar experience? Any solutions? Thanks in advance for any assistance!
