When I was visiting Japan (from Europe), Avast has detected several SIM card changes... while in reality I NEVER CHANGED MY SIM CARD.
The SIM card stayed in my phone the whole time. NO CHANGE AT ALL.
I restarted my phone a couple of times. Perhaps that triggered it. It turned out to be very expensive restarts.
The phone sent in total 38 SMS messages, to the Avast server and to my friend's phone, costing me over 25 Euro. My friend never received any SMS messages. I got charged anyway. Wasted money.
WHY IS AVAST SENDING SIM CHANGE NOTIFICATIONS WHILE THERE IS NO SIM CHANGE?
I found similar messages in this forum, but no response at all from Avast. Very disappointing. And expensive.
I'm getting rid of Avast and changing to PREY.
