Hi,
I have Avast on all my devices including a Nexus 5 running Lollipop 5.1.1. I live in usa but recently went to the UK and used a Lebara SIM. On changing the SIM card in the UK Avast sent me an email saying that had happened (good) but gave the new SIM info phone number as the original one from US. Now I am back and I changed back to my ATT SIM and received another email saying the number had changed to the UK phone number.
It seems Avast is one step behind my changes which would be no good if my phone was stolen and I was informed of a SIM change and it gave the old (my) phone number.
Maybe I have a setting wrong somewhere.
Thanks.
