How to change the color ringtone when moving?

Call 12530 to charge the basic call charges normally. There are both automatic stations and manual stations, but automatic stations will be more complicated and unclear. It is recommended not to use it. You may need the card's 6-digit service password.

It will be more convenient to log on to the website of 12530 CRBT. You can listen to the songs on the website first, and then choose which CRBT to order. However, logging in to CRBT requires a CRBT password.

The 6-digit password of the card refers to the service password, which is the password for opening the business and inquiring the detailed list.

CRBT password refers to the password sent by the CRBT enabled system on your mobile phone. If you forget it, you can get it back through the CRBT website. Please see CRBT website for details. Follow the steps.

After logging in, there is a personal ringtone library management on the website, and you can set, cancel or replace the downloaded ringtones.
