Incoming Caller ID/App

When I was a customer with T-Mobile, I had access to Name ID which shows my incoming and even outgoing Caller ID information, even if they were not in my contacts. Since I no longer have T-Mobile and I have XM, I don’t get that information. Is there a good app free or premium that I could try out for my iPhone 11 Pro Max?

Also, I have read that Comcast and T-Mobile partnered up together for that Stir/Shaken ID where incoming calls will tell you if they are a verified call or a spam/Spoof call and it’s for the iPhone and Samsung devices. I haven’t received anything like that on incoming calls. Can someone provide me more information on this?

Thanks so much!
