OTO Global International Calls

Hello, this is OTO Service Team.

We are pleased to inform you that it is currently difficult to use the OTO Global App.

As the problem of illegal use abroad increased excessively through our app, the load on the server was inevitably restricted.

We would appreciate your understanding that we have restricted our use as a measure to prevent malicious use by illegal users and to prevent harm to good users.

In addition, please kindly understand that recovery may take some time.

After that, we will try to provide better service.

Thank you.
