To check whether the three codes of a Huawei speaker are integrated, you only need to call up the string code in the mobile phone system and compare it with the string code in other locations. Open the dialer of the phone, touch the keyboard and enter \"*# 06 #\
First, the 15 digits recorded are compared with the IMEI1 code on the box of the phone, if they are inconsistent, it means that the phone is not genuine or the box does not match.
