The only thing that oFono core will poll periodically is the network 
operators.  Everything else must be handled by the driver.  For network status 
updates atmodem sends an AT+CREG=2, quoting 27.007:

"2 - enable network registration and location information unsolicited result 
code +CREG: <stat>[,<lac>,<ci>[,<AcT>]]"

This seems to work ok on my devices.  Are you sure your modem re-registers to 
the home network?

For signal strength oFono explicitly doesn't poll this in the reference 
driver.  This is because vast majority of vendors out there have their own 
specific command to turn on period signal strength updates.  If you want this 
feature, you need to submit a patch that enables this support explicitly.

No.

Nope, nothing like this is required.
