Looking at the DTEK 50 user manual, we are supposed to have WiFi calling. Page 26 says we do have WiFi calling. However, if I go into settings I have no reference to WiFi calling as stated on page 26. I am on Wind Mobile and they don't have WiFi calling, but I inserted my husband's SIM from Virgin Mobile which has WiFi calling and no luck either. We talked to Virgin Mobile and they queried whether this is some sort of screw up by Blackberry?
