What are the disadvantages of port number transfer?

The disadvantage of port number transfer is that the mobile phone number cannot be used normally in the process of port number transfer, and it can only be transferred to the official APP and business hall of the operator to recharge. The implementation of port number transfer requires operators to upgrade and maintain the existing network, user database and billing system, which will inevitably increase the network operation cost. If the response is not good, the computer system of Softbank in Japan may be paralyzed due to the influx of a large number of users, and it will have to announce the suspension of accepting new users five days later.

The advantages of port number transfer are: protecting users' right to choose and realizing more full market competition. The disadvantage of port number transfer is that it is difficult to obtain the qualification of network transfer and enjoy some call services and preferential activities.

Several situations in which the number cannot be transferred to the network:

1. During the contract period, you must first make sure that your mobile phone number is not within the contract period. There can be no activities such as "phone bill delivery" and "pre-storage 100 minute return".

If you participate in the activity of purchasing a phone bill, it will be stipulated that you are not allowed to close the account or change the package for one or two years. Naturally, I can't carry it.

2. Other service bindings, except the basic package, are all other services. For example, if you have opened a family number, joined the network age upgrade, or bound a broadband number, you can't apply for network transfer. You have to cancel all business, or wait until the activity expires.

3. The mobile phone is in arrears. In the process of transfer, once the mobile phone is in arrears, it will not be transferred out. I suggest that you try not to use that card in those days, so as not to incur expenses and lead to arrears.

Number portability, also known as number portability, means that users of one telecom operator can become users of another telecom operator and enjoy various services provided by them without changing their mobile phone numbers.

Number portability helps to support new operators and prompt them to enter the market quickly. The implementation of port number transfer is considered to be a measure that can benefit consumers, the country and the telecommunications industry.
