Most of the major telecoms seemed to tried to get into this ad targeting business. I think there is still Verizon Media and they still have a DSP? To me it makes huge sense to allow advertisers to bid on known user data - since cookies, IP address, iOS policy are killing that type of targeting for everyone except google. But they never seem to make it work and bridge that gap. ATT was looking to sell Xandr though they might not be going through with that I haven't read anything about it recently.
