        Short message service
 
-               The SMS support is available, but is currently still missing
-               some integration with the driver framework.
+               The SMS support for text messages is available.  oFono
+               supports concatenated messages of up to 255 segments, UCS2 and
+               GSM alphabets as well as extended alphabets.  SMS status
+               report features are not yet available.

+       Cell Broadcast
 
-       SIM PIN handling
+               Cell broadcasts should be fully supported by oFono, but have
+               not been well tested.  Base station name ids have been
+               confirmed to work.
 
-               At this moment only SIM cards with deactivated PIN request
-               are supported. The full support for SIM PIN is planned, but
-               not yet implemented.
+       GPRS
+
+               GPRS data connections are fully supported by oFono.  However
+               this support is currently limited to just one active GPRS
+               context (network interface).
+
+Work in progress features:
 
-       Cell broadcast and USSD
+       USSD
 
-               Both features are work in progress right now.
+               User initiated USSD support is available, but not
+               network-initiated USSD support.
 
-       GPRS data connection
+       PPP
 
-               No work on this has been done so far, but it is planned
-               feature.
+               Modems that use PPP for data connections are currently not
+               supported.  This feature will be available once a functional
+               userspace ppp stack is available.
