My Truma iNet Box does not receive SMS – why?
Perhaps you entered the wrong phone number for the iNet Box in the Truma App set-up wizard. To check this, copy the iNet Box phone number from the GSM set-up wizard, paste it into the selection field of the mobile phone and call it. Normally, it rings once or twice before you hear the busy signal. If this does not happen, check the phone number and set up GSM again with the correct iNet Box number.
