Some months ago I pointed out that the "message waiting indication" was not working for me. I know SMS handling has had a bit of a shake-up in the mean time, so perhaps it's worth pointing this out again. Or am I unique in seeing this as a problem?

Subject: SMS Message Waiting Indication
When someone leaves a voice message for me on the network operator's
voicemail system, I get what looks like an empty SMS from "Δ@" and
shortly after I listen to the voice message I get another one from "_@".
I presume this must be how my old Nokia phone knew when to turn on and
off its "o_o" icon.
I can display the relevant SMS with:
mdbus -s org.freesmartphone.ogsmd /org/freesmartphone/GSM/Device
org.freesmartphone.GSM.SIM.RetrieveMessagebook all
For example:
( 6,
'read',
'\xce\x94@',
' ',
{ 'alphabet': 'gsm_default',
'message-class': 2,
'more-messages-to-send': True,
'pid': 66,
'reply-path': False,
'status-report-indicator': False,
'timestamp': 'Tue Feb 9 17:42:53 2010 +0000',
'type': 'sms-deliver'}),
I know little about the innards of GSM, but a quick search turned up
3GPP TS 23.038, section 4, SMS Data Coding Scheme (DCS), field TP-DCS,
Message Waiting Indication (MWI), which looks like it could be describing
this mechanism.
Is this supposed to work? Can I do anything to help make it work?
If it did work, where would I see the equivalent of the Nokia's "o_o" symbol?
I'm using shr-testing on a Neo Freerunner with Orange (UK).
