1. After being elected as CRBT service company, you can give the advertising text and telephone number you want to do to CRBT service company (normally, the ringtone library will be completed within 1 working day). When CRBT arrives at the ringtone library, we will set it as the default playback. Log on to the mobile website of 12530 (for example, Guangdong 12530, Yunnan 12530, Zhejiang 12530) and search the CRBT websites of various provinces. After entering the website, log in with your mobile phone (the password can be SMS verification code).
2. After entering the ringtone library, you can set your company's corporate advertising ringtone as the default play. (The ringtone library can set playback modes such as time playback, sequential playback and default playback. Some people enter the ringtone library and find that they don't have their own advertising ringtones, so they look for a ringtone service company. )
3. After some settings are set to default playback, you can dial the phone or the song or the previous ringtone. In this case, you can delete the songs in my music box (because the operator's priority is group ringtone-ringtone in the music box-ringtone played by default).
Maybe after these operations, the previous ringtone will be played. This ringtone may be a group ringtone (with high authority and highest priority). You have to call the operator's customer service phone, ask the customer service to cancel the previous ringtone, and then set your own ringtone to play by default.
