If a prepay phone is running low on funds, the alert phone call might be
intercepted by the low funds notification.
On prepaid accounts, some carriers send a text message or voice call
after the first call of the day. Be sure to test how your service works.
If your phone supports it, the speed dial option is preferable to the re-
