</div>The problem of GrapViet
Drivers and passengers had to contact each other via regular phone calls. Each ride usually required drivers to call for 2-3 minutes, costing between 2000 VND - 3000 VND. For short trips, this cost could be significant (up to 10%).
Passengers also had their phone numbers exposed, leading to the risk of being disturbed after each ride.
How did Stringee help GrapViet solve this problem?
With Stringee Call API, GrapViet integrated the feature into their iOS/Android app and also into their CRM system, allowing employees to make free calls to drivers' apps.
