What do Hong Kong mobile phone price, VoIP price and monthly fee mean? I have been using this service in a telecom company for 4 months. How can I enjoy its benefits?

The net price of the machine is the price at which you only buy the machine. Communication companies are generally more expensive than communication shops on the market (such as those on the street in Mong Kok), because consumers are encouraged to go on stage.

Being on stage means signing a contract. For example, if you buy a machine in PCCW, the net price is 3000, and the price is 1000. If you go on stage, the monthly fee is 150. Then you need to sign a contract ranging from 12 months to 18 months, and use your credit card as a guarantee. Every month, PCCW will deduct 150 from your credit card, and it often takes several months, such as half a year, to pay this fee for the first time. That is to say, when you buy it, the down payment is 1000+ 150*6, and it will be deducted automatically every month after 6 months. The monthly fee usually includes a certain amount of talking time, the number of short messages and the internet traffic. You can choose a specific package.

Generally speaking, it is not allowed to break the contract at will. If you break the contract in advance, you need to pay compensation.

You used it for four months, depending on what you used. Only those related to your buying a new machine are affordable.
