Galaxy S8 - Not Registered On Network?


    I can't tell if this is a device issue or a network issue. My S8 is able to transfer data fine (streaming SiriusXM right now) but I can't make any calls because it says "not registered on data network." I can, however, make calls via WiFi.


    I know this issue is common on Samsung devices but I also see it mentioned from time to time with TMobile's help. I'm also in a parking garage if that makes any difference, though it shows two bars of coverage and data is fine.
