We are seeing the IP country as ++ and ?? for most of the mobile customers
In general, when you see ?? or ++, it means that the AA system could not find information related to your IP address:
?? - The IP address could not be translated into a geographic location. This can result if your GeoIP information
database contains old data. You can find a new copies of the GeoIP file in RSA Central. You can use your Reports Account (which looks similar to this RFabcd1234), to log in, and then find the GeoIP files under /rpt/geo/.
++ - The IP Address is considered an internal IP address, 10.*.*.* for example, and has no GeoIP information associated with it.
I hope this helps.
