Why is Guangzhou Conghua Card rented in October?

The monthly rent of Guangzhou Conghua Card is mainly for the flow cards of some Internet of Things devices. Because these IOT devices are put into use in large quantities, if ordinary mobile phone cards are used to pay the monthly fee, the cost is too high for enterprises to afford. Therefore, Guangzhou operators have specially created a monthly rent-free Conghua card to reduce the hidden costs paid by enterprises in the process of using the card and provide better and more convenient services for enterprises.
