What is the reason why I can't install SMS?

Reason 1: The number of SMS center is incorrect, because some models involve customized versions, and there are differences between parallel imports and ports. The SMS center numbers of these models are generally not from Chinese mainland, but the licensed mobile phones will become factory settings after refreshing or restoring the factory settings, which may cause the SMS center numbers to be mismatched. Because there are different operators in different parts of the country, the number of SMS center in each area is different, which further causes the confusion of SMS center numbers. The user's own setting error may also lead to incorrect SMS center number, so the main reason why the mobile phone can't send and receive SMS normally is mostly related to the wrong setting of SMS center number. Solution: Because different regions of the country have different carrier networks, the corresponding SMS center numbers are also different. If it is just a list, it will be a huge amount of data. In addition, for users, it is not only tedious to find the number of SMS center on the Internet, but also the version and year of many materials will cause inaccurate information. Here we suggest that you can go to the business hall of the local operator to find out. Generally, someone will help you find the most correct SMS center number and set it up.
