Extended information

1. MEI codes are uniformly allocated by GSM (Global Association for Mobile Communications) and authorized by BABT (British Communications Certification Board). The management organization for IMEI code review in China is: Telecommunication Terminal Testing Technology Association (TAF) Telecommunication Terminal Testing Technology Association, English name: Telecommunication Terminal Testing Technology Association, abbreviation: TAF.

2. Generally speaking, it is free for manufacturers to apply for IMEI codes. However, starting from October 2009, the European Equipment Model Certification Center, a neutral issuing agency authorized by the GSM Alliance, began to issue IMEI code requests to Chinese mobile phone manufacturers. Punitive charges are implemented. As long as the mobile phone is manufactured by a Chinese mobile phone manufacturer, the application fee for the IMEI code of each model is as high as 2,000 US dollars.
