What is inner dialing code?

Inner dialling or supplementary service codes (USSD codes) are sequences of numbers and symbols used to send information between a mobile device and a network service provider. They are typically used to access services such as checking account balances, recharging accounts, and activating or deactivating services.

Inner dialing codes are typically entered by dialing the code into the phone's dialer and then pressing the "send" button. Some codes may require additional information to be entered after the code, such as a phone number or account number.

Here are some examples of inner dialing codes:

- *100# - Check account balance

- *123# - Recharge account

- *111*123456# - Activate a service

- *110*123456# - Deactivate a service

Inner dialing codes can be a convenient way to access services from a mobile device. However, it is important to note that some codes may be charged a fee by the network service provider.
