Honestly, save yourself the grief and just accept the fact that NissanConnect/Carwings sucks and isn't worth the headaches...
The number of people having issues with the 3G TCUs is ridiculous and Nissan doesn't seem to be getting ahead of this issue. Early on, I felt that I needed Carwings but having not used it for months now, I don't really miss it. I now pre-heat the car using the climate control timer, which keeps my wife happy.
Even without TCU issues, NissanConnect is unreliable, slow, and provides a pretty limited set of features that haven't changed in years.
