    s4 won't connect to network and wifi calling gives a reg90 error.

      I can connect to wifi and use all apps except any calling feature or texts. I went in to a tmobile store and they thought it might be a block on my imei number. I checked a few different sites to search if my number was blocked but all the sites said I was unblocked. I've tried taking the battery and sim out for a day but nothing has helped yet. Any insight would be much appreciated.
