Wi-Fi Calling lets your phone make and receive calls and texts over your Wi-Fi network and through the internet rather than through a cellular tower and network. Your carrier ultimately handles the call, but the connection is not routed through the dedicated cellular system.
Wi-Fi Calling is usually enabled in cell phone settings without the subscriber knowing, and calls/texts will likely route over Wi-Fi if present (even if the cellular network is available).
Why Wi-Fi Calling Is Often a Problem (and Sometimes Best to Disable)
While it can help in certain situations, many users have more trouble than benefit.
1. Wi-Fi networks are not designed for voice-call stability
Voice calls require:
- Consistent upload bandwidth
- Low jitter and low latency
- No packet loss
Wi-Fi network service can fluctuate constantly due to other user traffic and is subject to “Best-Effort” data routing when it is handled by your ISP (once it leaves your work/home network). Even small fluctuations can cause:
- Choppy audio
- Delays
- Calls dropping
- One-way audio
2. Your phone may constantly “ping-pong” between Wi-Fi and cellular
If the Wi-Fi signal weakens, even briefly, your phone may switch back and forth between LTE/5G and Wi-Fi Calling in the middle of the call. This handoff is often not smooth, leading to:
- Silence
- Audio dropping in/out
- Call drops
Moving between rooms or areas, or the use of mesh Wi-Fi systems, can make things worse.
3. Router compatibility issues
Some routers mishandle the features Wi-Fi Calling needs, like:
- SIP/IMS traffic
- NAT traversal
- QoS (Quality of Service)
- UDP port handling
This often breaks calls on certain routers, even when normal internet use is fine.
4. Wi-Fi networks may be set to block or throttle calling traffic
Many hotels, campuses, hospitals, and workplaces block the ports or protocols required for Wi-Fi calling. Result: calls fail, voicemail doesn’t update, or texts don’t send.
5. Wi-Fi Calling can be slower to initiate calls
Because the phone tries Wi-Fi first, then falls back to cellular, users often notice:
- Delay when dialing
- Delay when receiving calls
- Missed calls that went straight to voicemail
Summary
Wi-Fi Calling is great in theory, but often problematic in real-world conditions because Wi-Fi networks are less stable than cellular networks and not optimized for calling. Most phone users experience more reliability, fewer drops, clearer audio, and faster call setup when they disable Wi-Fi Calling and rely on cellular unless they live in a poor signal area.
General steps to turn Wi-Fi Calling OFF on your cell phone:
iPhone (iOS)
1. Open Settings
2. Tap Cellular (or Mobile Data)
3. Tap Wi-Fi Calling
4. Toggle Wi-Fi Calling on This iPhone to OFF
If your phone supports dual SIM/eSIM lines, repeat for each line if needed.
Samsung / Google / Android Phones
The wording may vary slightly by brand, but the steps are similar:
Samsung (Galaxy series)
1. Open the Phone app
2. Tap the three dots (⋮) in the top right
3. Tap Settings
4. Select Wi-Fi Calling
5. Toggle Wi-Fi Calling to OFF
Alternative path: Settings → Connections → Wi-Fi Calling → OFF
Google Pixel
1. Open Settings
2. Tap Network & Internet
3. Tap SIMs
4. Select your SIM
5. Toggle Wi-Fi Calling to OFF
Motorola / OnePlus / Other Androids
1. Open Phone app
2. Tap Menu (three dots)
3. Tap Settings
4. Look for Wi-Fi Calling
5. Turn it OFF
If not inside the Phone app settings:
Settings → Network & Internet → Mobile Network → Advanced → Wi-Fi Calling
Carrier-Specific Notes
Some carriers place the switch in different menus:
Verizon
Often under: Settings → Network & Internet → Mobile Network → Advanced → Wi-Fi Calling
T-Mobile
Frequently under: Settings → Connections → Wi-Fi Calling
AT&T
May appear under the Phone app’s Calling menu instead of the system settings.
Confirm It’s Off
On most phones, once it’s disabled:
- You will no longer see "Wi-Fi" or "Wi-Fi Calling" in your status bar during calls
- Calls will say LTE, 5G, or VoLTE instead
- Note: that settings may change after cell phone software updates. If you experience problems in the future, recheck your Wi-Fi Calling settings.
