This is likely. Rogers One Number is probably causing issues with RCS and it is supposed to be decommissioned today. I noticed it no longer appears as an option on my device in myRogers.
I had One Number and I am now getting Enhanced Messaging on my Dtek50 device with Rogers. It is also working for Fido customers too (I can personally say it works on Fido with a Nexus 5x)
No factory reset was needed. I opened the app, and a banner was at the bottom of the app screen stating the option for enhanced messenging.
Does Rogers extreme messaging/texting still work as normal with Android RCS or with RCS enabled, extreme text rules won't work/apply?
