Have a new 6s. My husband seems to think he checked off BOTH "advanced calling" AND pay $0.99 for ringback tones when adding features to my phone he got me for Christmas. Obviously RBT & AC are non-functional together. I have turned off "HD calling" on my device according to the posted instructions but cannot access ringback tones. How do I remove "advanced calling" from my "plan" and activate RBTs? I would rather have the latter, especially considering I paid $20 for these RBT 3 weeks ago.
thanks!
