Difference Between VoIP and VoWiFi
Let Me Explain You the Basics
Today, we are going to explore the difference between VoIP and VoWiFi. Both are used for making calls over the internet, but the way they work and where they are used is different. I will explain you this in a clear and simple way.
What Is VoIP
VoIP means Voice over Internet Protocol.
This is a general technology that lets you make voice calls using any internet connection — whether it’s Wi-Fi, mobile data, or wired broadband.
You use VoIP when you call through apps like Skype, Zoom, Microsoft Teams, or WhatsApp.
What Is VoWiFi
VoWiFi means Voice over Wi-Fi.
This is a specific type of VoIP that works only through a Wi-Fi network and is usually integrated directly into your smartphone’s dialer.
VoWiFi lets you make regular phone calls over Wi-Fi even when you have weak or no mobile network signal, but you do need Wi-Fi access.
Now Let Me Show You the Key Differences
- Technology Scope: VoIP is broad and works through any internet source. VoWiFi is focused only on Wi-Fi-based calling using the native phone app.
- App or System: VoIP runs through third-party apps. VoWiFi works directly with your phone’s built-in dialer (if supported).
- Internet Requirement: VoIP can use Wi-Fi, mobile data, or broadband. VoWiFi uses only Wi-Fi.
- Mobile Network Involvement: VoIP usually does not use your mobile network provider. VoWiFi is connected to your mobile number and carrier.
- Caller ID: VoIP calls often show app usernames or numbers. VoWiFi calls use your actual mobile number.
Let Me Compare It in a Table
| Aspect | VoIP | VoWiFi |
|---|---|---|
| Works Through | Any internet (Wi-Fi, mobile data, broadband) | Wi-Fi only |
| Requires App | Yes, uses third-party apps | No, uses phone’s built-in dialer |
| Mobile Number Use | Not required | Required |
| Carrier Dependency | Independent from mobile carriers | Works with your mobile carrier |
When You Use VoIP
You use VoIP when:
- You are using apps for personal or business calls
- You need calling features like video, screen sharing, or chat
- You are not relying on your mobile network number
When You Use VoWiFi
You use VoWiFi when:
- You are in an area with poor mobile signal but good Wi-Fi
- You want to make and receive calls using your phone number over Wi-Fi
- You want a seamless experience through your phone’s regular dialer
So now you understand the difference between VoIP and VoWiFi. I’ve explained you how VoIP is the broad method for calling over any internet source, while VoWiFi is a built-in mobile feature that uses Wi-Fi to keep your calls going even without mobile signal.
