Hi Tim,
Yes you are absolutly right.
Allow Direct Push when roaming: Select this check box to enable the mobile phone to synchronize as new items arrive when you're roaming with your phone. You're roaming when you're outside your normal service area. Check with your
mobile service provider to determine your normal service area. Clearing this check box forces you to manually launch synchronization when you're roaming with the phone and data rates are traditionally higher.
