• If you use more than
your monthly allotment, you pay a much higher charge for the extra
minutes.
• Unused minutes may
not carry over to the next month.
• Most wireless plans
count the minutes for both calls you make and receive.
• Charges are usually
rounded up. For example, a call that takes one minute and three seconds
may be charged as a two-minute call.
• Unlike traditional
phone service, most wireless providers start the clock when you press
the "talk" or "send" button, not when the person at the other end of the
line picks up.
• You use minutes when
you call toll-free numbers.
• Some services allow
you to check by telephone or online to find out how many minutes you
have left in your billing cycle. Depending on how often that information
is updated, it may not be absolutely current.
