This hasn't happened to me (yet), but decided to
check mine. Had to pop the SIM out to micro to fit the only spare cellphone here, and a marketing SMS from Telstra appears dated the previous day. Fitting it back in the 9555 with an adapter is a bit fiddly though.
Checked the account on-line. No spurious charges.
[Edit:] Further to my comment above, there were things I DID make sure of when I first set this service up - NO DIVERTS, and NO VOICEMAIL.
If the unit is switched off, the caller receives the RVA "the mobile you are calling is either switched off or not in a mobile service area" and is NOT offered the leave-a-message option.
If while switched on (and registered on the network) the mobile is called and does not answer, it does NOT divert to anything - it just rings out.
Maybe this is why I haven't attracted any extra charges over the years.
