Automating data reset on SIM cards using USSD commands can be a effective way to manage mobile data usage without requiring manual intervention. Unstructured Supplementary Service Data is a real-time protocol used by GSM networks to communicate with service providers. Unlike data-dependent apps, USSD functions over voice channels, making it perfect for remote areas.

Various telecom operators offer dedicated dial strings to reset or refresh data allowances. These codes may differ regionally but typically begin with * and end with #. Creating an automated reset system involves setting up a solution that triggers these codes at intervals, such as when data usage exceeds a limit.

A common method is to use a 2G connected to a embedded system like a Arduino. The modem can be managed using command-line instructions over a UART link. By writing a Bash automation script, you can initiate the request. For example, sending AT+CUSD=1,"YOUR_CODE",15 will start the carrier interaction. The modem will then return the carrier’s response, which can be checked for success keywords to confirm the action was processed.

Scheduling the script with cron jobs enables complete automation. For instance, a user might trigger a reset weekly on weekends to maximize speed. The system can also check current usage via another USSD code and skip reset if under limit, ensuring efficient plan usage.

It’s critical to note that some networks disable data resets via USSD. Alternative methods include calling customer service. Always check official documentation that the USSD code you intend to use is valid and active. Also, excessive automation may break your contract, so understand provider policies before deployment.

Protecting the system is essential. If the automation controller has internet access, ensure it is firewalled and encrypted. Do not use default logins on the device. The embedded unit should have no public ports open to prevent unauthorized access.

Particularly beneficial for businesses managing fleets of IoT devices, field-deployed equipment, or any scenario requiring zero-touch management. It also benefits users with limited plans to avoid overage fees without daily checks.

While automation brings convenience, it is should complement monitoring usage habits. Check usage dashboards to confirm reset effectiveness. Always test with a single SIM before rolling out broadly.

To conclude, automating data resets on SIM cards with USSD is a viable solution for anyone needing to avoid exceedance penalties. With the compatible device, a reliable program, and carrier support, it can become a reliable method to optimize costs without overspending.
