The ports in the same city and Anjuke are charged quarterly. The port in 58 cities is about 2000-3000 a quarter, which translates into a monthly fee of 700- 1000, but generally speaking, your company will bear half of the cost of the paid port, so the port fee in 58 cities is about 350-500 a month.

You can also change a port that doesn't need to pay quarterly, and there is no guarantee. You can also try the circle port mode and fix how many customers will send a micro-chat package.

I hope the answer can help you.
