Note that using a single profile in multiple countries implies that there is a common ESSID
to connect to in each country. This is less likely than having unique ESSIDs in each
country, this requires unique profiles for each country.
For additional efficiency when using multiple profiles that can be used in multiple countries,
the country setting for each profile can be set to a specific country. If the current country

does not match the country set in a given profile, then that profile is disabled. This can
make profile roaming occur faster. For example, if two profiles are created and configured
for Japan, and two more profiles are created and configured for USA, then when in Japan
only the first two profiles are active, and when in USA only the last two are active. If they
