PDP (Packet Data Protocol) authentication works by verifying the identity of a user trying to access a mobile data network. When a user's device connects to the network, it sends a request to the PDP context activation function. The network then authenticates the user by checking their credentials, such as username and password, against a subscriber database. If the credentials are valid, the user is granted access to the data network, allowing them to send and receive data. **
