I've got a group plan for our devices and I was logged under the main number, trying to buy ringback tones for a different device. I selected the device before buying the ringback tones. After buying them and setting them up, I test called to see if they were working and it wasn't on the phone. Instead, it is on the main phone. I logged in under the other device to manage the ringback tones, but none of the ringback tones that I bought under the main number are seen in the jukebox area. Do I have to buy all these all over again or is there some trick I'm not seeing here?
