Switching SIM Card

I have 2 SIM card which I switch quite often when I travel between 2 country. Both SIM card has been inserted before hence it should be in the trusted list.
However I receive email notification with the subject “avast! Account Notification - SIM card or phone number update” when I switch between the SIM card.

Content is

The SIM card or phone number data of your device Galaxy Nexus has been updated.
Owner: N/A
Old IMSI: xxxxxxxxxxx
New IMSI: xxxxxxxxxxx
Old phone number: xxxxxxxxxxxxx
New phone number: xxxxxxxxxxxxxx

Is this information sent via SMS?
I use data on both SIM hence I want to know if the above information is communicated using SMS or data. Since I believe SMS should only be sent when new SIM card is inserted. I hope it doesnt generate SMS charges when I switch between my trusted SIM.

SIM changes are always communicated by SMS. Which countries do you travel in ?

I travel between Singapore and Malaysia which is very close by.
When I switch the SIM at the border and it could still hook on to the previous country network as roaming and it will incur expensive roaming SMS charges and not to mention if avast reporting number is an overseas one.

If it’s a trusted SIM, I believe it should not need to report via SMS.
Would be good if this can be set as an option that trusted SIM need not be reported so that we do not need to incur expensive roaming SMS charges.

i will look at your issue.

OK next bugfix update will contain a fix to make sure that every IMSI is only communicated once to server by SMS.

Has this been implemented in version 2.0.2589? Since that update came after your comment.
Because if it has, then it doesn’t work

yes it is fixed there. what is your exact issue? note that an IMSI is ONCE communicated to the server, further SIM changes then wont send SMS anymore.

The issue is when I change my SIM card to one that is trusted as the SIM card has been inserted previously, SMS was still being sent. So it’s doesn’t appear to only sent once only.

Can you get me a log?

a) Create an empty file called “avast-debug” on your /sdcard root directory
b) REBOOT your phone
c) Now Avast generates a lot of log
d) Try to reconstruct your problem
e) After 10 minues, open Anti-Theft (NOT Mobile Security) and go to the feedback screen (About)
f) Check “Send system log”
g) Create a case there giving your email address and mention this conversation as well as a short description of the problem (maybe someone else will get the case)
h) Then remove the avast-debug file from the /sdcard root directory again
i) REBOOT your phone
j) Everything back to normal
