What About Video Calls?
Unlike voice-only calls, video calls are data-hungry. Apps like Zoom, FaceTime, WhatsApp, and Google Meet can use 2–3 MB per minute or more depending on video quality. HD video calls can consume up to 1 GB per hour.

If you're using video calling regularly without Wi-Fi, you’ll want to monitor your data usage closely.

How to Check If Calls Are Using Data
If you’re unsure whether your calls are using data, here are some ways to check:

Check the app: If you're using WhatsApp, Messenger, or Skype, you're using data.

Check your data usage: On iPhone or Android, you can view app-specific data usage in settings.

Call type indicator: Some phones ceo email list show “Wi-Fi” or “VoLTE” next to the call icon—indicating it may be using an IP-based service.

Use Wi-Fi whenever possible – This is especially important for video calls.

Turn off video during VoIP calls if audio is enough.

Limit background apps – Some apps run in the background and consume data during your calls.

Check data settings in apps – WhatsApp and other apps have options to reduce call quality to save data.

Monitor your monthly usage – Use your phone’s data tracking tools or third-party apps.

Conclusion
So, does making a phone call use data? The simple answer is: It depends. Traditional cellular calls do not use mobile data, but VoIP calls and Wi-Fi calling do.

Understanding the difference between voice networks and data networks can help you manage your usage and avoid unexpected charges. Whether you’re on a limited data plan or just curious, knowing when and how your calls consume data can make you a smarter, more efficient phone user.
