Cannot get groups texts from Androids/RCS waiting for activation

That is not even an accessible feature. 

@user_aabb64 Thanks for sharing those details. It sounds like you've already done quite a bit of troubleshooting and suspect the issue may be related to how RCS is provisioned on the line rather than a device setting. We can certainly take a closer look at the line configuration and verify whether anything may be preventing RCS from activating properly. Please send us a direct message with your full name and service address to get started.
