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 (found via

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 had all been configured for
