The core function of Modem POOL

Multi tasking communication: Cat pools usually have multiple SIM card slots built-in, which can manage up to hundreds of SIM cards simultaneously and enable independent operation of different channels. For example, some devices support single channel multi card rotation, so that even if one SIM card reaches its usage limit, it can automatically switch to the next card [7].
Batch communication management: Through the control software of Cat Pool, users can achieve functions such as batch dialing, SMS sending, and number switching, greatly improving communication efficiency.
Data transmission bridge: Cat Pool can not only handle voice and SMS, but also support mobile data transmission, providing Internet connection for terminal equipment through cellular network.
