What is SMS Tracking?

SMS tracking involves monitoring and recording the progress and status of SMS messages from the sender to the recipient. This process typically includes tracking the sent messages to confirm delivery, providing details such as timestamps, delivery notifications, and, if applicable, any errors or issues encountered during the delivery process. SMS tracking is essential for ensuring the successful transmission of messages. The primary tool for SMS tracking is the SMS log file, in which data on the status of the sending are recorded.

What is SMS credit management?

SMS credit management involves monitoring and controlling the allocation of text messaging credits to users. Each sent SMS is tracked in a log file, and the corresponding SMS credit number is reduced accordingly. This log file provides a transparent record of SMS usage, helping users track their remaining credits and determine how many more SMS messages they can send within their allocated limit.

How often should I check the communication log?

Checking the communication log regularly is advisable, especially after sending important SMS messages or if you encounter any issues with message delivery.

The log file can be downloaded, and its location is specified during the download process. This flexibility enables users to review SMS communication logs conveniently. Depending on the settings, different log files are created, so several types of SMS log files are created. Such is, for example, the log file of SMS clients, but a separate log file can also be created for the service provider connection or SMS APIs. When setting the log file writing, we can also decide what type of log file we can create. Each user can only read their own log file. System-level log files can be viewed with appropriate permissions.
