Boomerang Call is a call request app.

If you ask a friend for a phone call, a friend calls you.

The caller can make free calls.

(When a friend uses a voice call free plan, their friend will also make a free call.)

Unlike conventional data calls (mVoIP), the phone is the same as the quality of a mobile phone phone because the friend makes a phone call.

Invite your friends to join the boomerang call with a friend invitation.

With just a few simple setups, you can call your friends.

Boomerang calls use a small amount of data.

This is the data you use to request a call or receive a request.

Thank you for choosing Boomerang Calls.
