What kind of ringtone is suitable for office use?

When using a mobile phone in the office, ring as slowly or slowly as possible. First, the office is very quiet, there is no need to make an explosion, and then it will affect other colleagues' offices.

In addition to choosing the right ringtone, we should also pay attention to the volume. When working in the company, try to turn the bell down to the level that you can hear, or turn it into vibration.
