USSD
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.
