Tips for Cheap International Calling
Use WiFi Calling
VoIP apps work best on WiFi. This saves mobile data and often provides better call quality.
Check Time Zones
India is UTC+5:30. Check the time at your destination before calling to avoid disturbing people at odd hours.
Avoid Roaming Charges
If abroad, use WiFi calling instead of roaming. Roaming international calls are extremely expensive.
Use + Instead of 00
The + prefix works worldwide and is easier to remember than different country exit codes.
