I would like to ask, does port number transfer have an impact on SMS reception?

Number portability does not affect SMS reception.

Number portability is also called number portability, and the number will not change when the machine moves. For example, mobile phone users with mobile numbers will switch to China Telecom network or China Unicom network to enjoy the communication operation services provided by China Telecom or China Unicom. Number portability mainly includes fixed number portability and mobile number portability. 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. Number portability is not only beneficial to consumers, but also to optimizing the market structure. Through market control measures, effective competition can be achieved and consumer welfare can be improved. For consumers, number portability can reduce the user's network transfer cost. For a country, number portability can save number resources. Number portability can break the dominant position of existing telecom operators, thus promoting market competition and optimizing market structure. After the implementation of number portability, number resources are usually managed centrally by third parties, which also saves social resources.
