Wi-Fi calling issues on WhatsApp can be frustrating, especially when you can see messages are getting through but calls won’t connect. Let’s break down why this common problem happens and how to fix it.
Understanding WhatsApp’s Different Connection Requirements
Think of WhatsApp messages and calls like two different types of mail – messages are like postcards that can squeeze through any mail slot, while calls are like oversized packages that need a wider doorway. Messages require minimal bandwidth and can get through even when your connection is weak, but calls need a more robust and stable connection to work properly.
Common Reasons for Call Failures
1. Network Restrictions: Your internet service provider or workplace might be blocking VoIP (Voice over Internet Protocol) traffic while allowing basic messaging. This is particularly common in certain countries or on corporate networks.
2. Bandwidth Issues: If you’re connected to Wi-Fi but the signal is weak or congested, messages can still trickle through while calls fail. It’s like trying to push a large file through a very narrow pipe.
3. Router Settings: Sometimes your router’s firewall settings can interfere with WhatsApp calls while letting messages pass through. This is especially true with older routers or ones with strict security settings.
How to Troubleshoot
Start by checking your Wi-Fi signal strength. If you’re getting just one or two bars, try moving closer to your router. Sometimes simply switching to mobile data can reveal whether the problem is with your Wi-Fi connection or something else.
Here’s a quick checklist to work through:
– Restart your WhatsApp application
– Check if your WhatsApp is updated to the latest version (as of 2025)
– Toggle your Wi-Fi off and on
– Ensure your phone’s date and time are set correctly
– Check if calls work on other networks
When Messages Show as Delivered but Calls Don’t Connect
If you’re seeing those two blue check marks on messages but calls won’t go through, it usually means you have just enough connectivity for basic data transmission but not enough for sustained voice or video communication. Think of it like having enough water pressure to fill a glass but not enough to run a shower.
The Technical Side
WhatsApp calls require a consistent connection speed of at least 64 Kbps, plus they need certain ports to be open on your network. Messages, on the other hand, can get by with much less bandwidth and fewer technical requirements. That’s why you might see messages working perfectly while calls remain stubbornly unavailable.
Remember, WhatsApp is constantly updating its requirements and features, so what worked in previous versions might need adjustment in 2025. If problems persist, you might need to reach out to your internet service provider or check for any network restrictions in your area.
