SL6087 AVSAMPLEDEMO SAAMPLE Failed

Hello ,
Can someone explain me why the application AVSAMPLEDEMO didn’t send a text message just after starting it and thx for help??
By accident I removed the SIM when the application is running and i got these trace in the console

[LOG] [flash] [DEBUG]: "loading flash chunk require"

[LOG] [flash] [DEBUG]: "loading flash chunk sched"

[LOG] [flash] [DEBUG]: "loading flash chunk log"
