If Rogervoice does not recognize your phone number, and an error message appears "An error has occurred!", check if you are under a WiFi or 4G data. If you were on WiFi, try 4G or vice versa.
If the problem still persists, activate the mobile data in your phone Settings > Rogervoice.
Also activate Mobile Data by going to Settings on your iPhone > Cellular Data
