the action is triggered if we find a SIM in the phone where we do have no phone number record on the server yet.
My usage bill also shows 5 SMS sent to Avast no. this happened with following conditions:
1) I switched my SIM card with a new one.
2) My earlier SIM was still working perfectly.
3) Avast anti-theft was properly working and Friend nos. were correctly saved in settings.
So my point is:
1) when I had proper settings with Friend nos. saved, why did your software sent SMS to your no. and not to my back-up numbers?
2) why your account profile page gives options for activating/de-activating e-mails but not SMS?
Kindly add features to give preference to e-mails or SMS to Friend numbers and not Avast no.
