If your device is set to synchronize automatically when items arrive,
ActiveSync uses SMS messaging behind the scenes to communicate to
your device when an item has arrived. Depending on your rate plan, SMS
messages may have costs associated with them on a per-message basis
or as a monthly allotment. To reduce SMS messaging costs associated
with this feature, schedule synchronization automatically when items
arrive during times when mail volume is low.
Be more up-to-date
Keeping the information on your device always up-to-date requires more
frequent synchronization. If your priority is to stay up-to-date, recharge
your battery frequently and synchronize often. During periods of high mail
volume, you can stay up-to-date efficiently by scheduling synchronization
at frequent intervals. During periods of low mail volume, you can stay
up-to-date efficiently by scheduling synchronization automatically when
items arrive.
Contact your ISP or network service provider (such as your cellular
phone network provider) to confirm the details of your rate plan.
The power-off timer is reset each time the device synchronizes. If you
set a synchronization schedule that is more frequent than the time set
for the device to automatically power off, the device will never turn off
to save battery power.
