How to set color ring tones when Unicom sends short messages?

At present, the setting mode of Unicom ringtone does not support SMS, which can be set in two ways:

1: you can dial 10 150 (automatic voice service) in the province, press 1 according to the voice prompt, or press No.2 to download, press # when listening to the ringtone to confirm, and then press 1 to set the default ringtone. 2G, 3G and 4G users call this number and charge 4 cents per minute;

2. You can log on to the website of CRBT to make a choice.

Tips: No matter how you download ringtones, each downloaded song ranges from 0 to 3.5 yuan.

Tips: Take Anhui Province as an example. There may be differences in policies among provinces and cities, and the attribution policy shall prevail!
