+- Support for PLMN_MODE bit from CPHS Customer Service Profile (CSP) within
+  the 'Value Added Services' service group.  oFono reads this file when the
+  network registration atom has been initialized.  If EFcsp indicates that
+  manual network registration is not allowed, oFono enters into 'auto-only'
+  registration mode.  Updates to this file via STK Refresh is also supported.
