Otoku Call is an application that can automatically place a number called a “prefix” that is specified when making a call before the destination phone number. (Prefix number is not displayed to the other party, only your phone number is displayed.)

If you want to use Otoku Call, you need to apply in advance to the MVNO operator to which you have a contract.

【Notes】
・ You cannot make calls to connection services such as emergency calls (110, 119, etc.), other 3-digit special numbers, incoming billing services, and Navi Dial (0570). It is a normal call without a prefix number.
・ Please use this app on a terminal that can make voice calls.
・ International calls are not eligible for the unlimited call option, and the rates for each country vary. For details on available countries and calling charges, check the service site of each operator.
-Even if you do not use this app, you can use the prefix service you have subscribed to by entering the prefix number manually. However, it is recommended that you use this app because there are concerns about entering the prefix number and incorrect input.
