DialLink is a VoIP (Voice over Internet Protocol) service, which means it uses your internet connection to make and receive calls. If you're not connected to WiFi, DialLink will use your mobile data.
On average, DialLink uses about 0.5 MB of data per minute of voice call. That’s approximately:
30 MB per hour
250 MB for 500 minutes of talking
To avoid extra charges, we recommend using WiFi whenever possible, especially when traveling or if your mobile plan has limited data.
