Network Messaging, also known as Unstructured
Supplementary Service Data (USSD) is a protocol that can be used to
communicate from your device to your service provider. Depending on
which network you use for your mobile broadband service, this page can
be used for a variety of network services such as balance checking,
recharging a prepaid service, and many others.
Network messaging can be initiated using special
codes specified by your carrier for these various services. Once a
special code is sent to the network, the network responds with the
requested information. The response often includes instructions for
sending additional follow-on messages allowing further functionality
(e.g entering credit card information for a credit recharge).
Please contact your network provider to learn
which codes can be used on your network for features such as balance
checking, recharge, etc
To begin using this feature, please enter the
dial string (e.g #100#) into the box below and click "Start Session". If
you don't know which dial string to use, please contact your carrier,
and ask them which dial codes are suitable for network services.
