MOS is an online chat and call app for young people

MOS advocates pure communication and simple chat. No matter the people around or thousands of miles away, they are likely to be the same people. We need to share our joys and sorrows with others and explore the same interests together, because we are not alone.

If you need the help of MOS customer service, please find the "complaint" button in the app to contact us or leave us a message

Please give us your feedback, which is very valuable to us
