Ive searched for this app everywhere hidden, in galaxy and play store apps, main settings after system apps, T-Mobile USA website no where I look has it. I have a Samsung Galaxy S8 and all I did was go under main settings storage and then disable. It seemed to have completely gotten rid of it. This all started because I was trying to get it enabled, it was giving me a error telling me I couldn't mess with it unless I was the PAH.... I very much so have been, and after dropping my family allowances feature was dropped. HELP!!!!!!!

I could be mistaken but I know that T-Mobile uses the Hiya service and Hiya is built into Samsung dialers now. So because the T-Mobile ID feature uses the same service as what is built into the Samsung dialer it may have been considered a redundancy.https://hiya.com/blog/2017/08/23/samsung-phone-dialer-local-search-engine/
