all text messages. The number is stored on the
SIM card, but you can change the number and
enter another number in MENU.
A fee for making a phone call is charged as soon
as the phone call is made. To learn more about
charging details, contact your service provider.
Enable Delivery Report option. As soon as the
text message is delivered to the recipient, you will
get a return message (network feature).
