Handle provisioning APN by turning off/on data.

Handle provisioning APN by turning off/on data.

This is a start and two tests succeed:

Tested expired AT&T SIM and waiting 15min for alarm to fire.
Tested a provisioned Verizon SIM and works normally.

I've NOT tested AT&T where I've properly completed the provisioning.
I've NOT tested T-Mobile SIM either provisioned or not-provisioned.
I've NOT tested provisioning over WiFi.
I've NOT tested that WiFi <-> Mobile works
I've NOT tested voice calls, SMS, MMS
...

The current bug is below, but it is poorly named either it should be
renamed or a new bug created.
