I have a Lumia 525 running Cyan. Is there any way to bar all apps or the system to send outgoing SMSs. Or atleast ask for a password/PIN or permission before any SMS is sent?
EDIT: The reason behind the question. Few months back, I had gone out of the country with international roaming activated. My phone was an Android. In my next bill, I got one SMS sent from my phone everyday I was carrying it out the country, none of which I sent. I could never discover which App or anything else sent it.
Now I am going out of the country again & I don't want my Windows Phone to send any text messages while I am there.
