Flash calls are emerging as a new challenge for mobile network operators (MNOs). These calls provide a means of authentication similar to SMS one-time passwords but are more cost-effective. However, they pose regulatory and revenue challenges for MNOs, who may not receive payment for zero-duration calls.
