What is a software certificate?

What is a mobile phone certificate? The mobile phone certificate is only for S60 3rd mobile phone, which is what we usually call S60 third edition mobile phone. The S40 and S60 first and second edition mobile phones do not need to apply for a mobile phone certificate. The S60 3rd mobile phone uses Symbian's OS9.1 0S9.2 and 0S9.3 systems. This mobile phone system greatly improves the security of the mobile phone and can effectively prevent harmful mobile phone files, such as viruses and Trojans, from invading your mobile phone. Cause unnecessary losses to you. Everything has advantages and disadvantages. The third version of the S60 mobile phone has enhanced the security of the mobile phone, but it also brings a lot of inconvenience to our daily installation of mobile phone software. Because software that has not passed the mobile phone security system certification will be regarded as harmful software and the mobile phone software cannot be installed. Symbian officials provide a way to pass the security system authentication of mobile phones by applying for a certificate file suitable for their own mobile phone IMEI. However, because Symbian officials stopped applying for certificates on personal mobile phones, this caused a lot of inconvenience to the majority of mobile phone players. Symbian currently only allows large customers and third-party software development customers to apply for mobile phone certificates. We need to purchase a high-authority PID file issued by Symbian to apply for a mobile phone certificate. The high-authority PID provided by the official is expensive. .
