Modem saving SMS to SIM

[Dave McLaughlin]

I have ported a generic RIL for a Huawei modem that is now working and I can send and 

receive SMS and I finally got PPP to work.

The issue I have is that the system is saving all of the received SMS to the SIM so once 

this fills up I can't receive any more messages.

I can go into the message app and then settings and manage SIM messages and delete 

them but as this unit will eventually be located in a remote location, I need a way to 

delete these as they are received.

My application is enabled to receive them as highest priority and I then call abortBroadcast() 

to prevent the standard windows message app from receiving them. In fact, even if I do let it 

receive them, they are still saved on the SIM.

In the RIL, there is a function setPreferredMessageStorage(void) function and this is currently

set for AT+CPMS = "SM,SM" which would indicate SIM storage.

When I receive the message, I call the getStatusOnIcc() which returns -1 indicating non

SIM (ICC) message.

I don't see any Android call that deletes these messages from the SIM.

The unsolicited result code for messages is +CMTI indicating from the SIM but the code

also have a handler for +CMT but when I read the RADIO logcat entry, it is always +CMTI

Does anyone know how to enable the system so that either messages are not stored in

the SIM or that they are deleted on reception after being received?

Good question. Did you ever find an answer?

Check settings app source code. we have an option where we want sms to be stored. if you track that function call, you will know how to do this.
