It depends. TellMe, 800-555-Tell, was originally owned by AT&T, and still may be after all the mergers. AT&T Wireless phones used TellMe for 411.
Here in my area, I live fifteen minutes away from a huge Verizon call center that handles both wireline and wireless directory assistance calls. They handle VZW phones and also contract out to other carrieers.
