First things first, if the Wi-Fi Calling is not enabled the feature won’t work!
That’s right. This is an optional feature that comes along with the services of many mobile carriers, that is optional on your device.

Perhaps, there’s a problem with the Wi-Fi feature on your mobile device!
users often are unable to connect with a Wi-Fi network, due to their phone’s adapter receiving interference or being temporarily out of service.
There’s an easy solution to that problem and it is to restart the Wi-Fi feature of your mobile device.
Let’s learn how!
How to Restart Wi-Fi on mobile:
- Launch the Settings App on your device.
- Navigate to “Wireless”.
- Press “Wi-Fi” to access the WiFi settings.
- At the top of the page, press the Activation Slider.
- Wait for 50 Seconds while the Wi-Fi is disabled.

It may take your phone a while to establish a connection with your network device.
Note: The state of connection will be displayed on the top-left of your device!
As you probably assume, Connection Strength is the key to achieving proper Wi-Fi Calling.
- This solution won’t help users who are connected to a public Wi-Fi Network
Thus, standing too far away from your network device may result in a weak Wi-Fi connection, or completely kill the service on your phone.
What you’ll have to do next, is make sure that you’re standing as close as possible to the network device.
Get your phone, make sure it is connected to the Wi-Fi and head next to the router. Only then, attempt to perform a Wi-Fi Call using O2’s wireless services.
We recommend using the 2.4Ghz WiFi broadband of your router for more reliable and consistent signal strength.
Tip: On a 5GHz Wi-Fi thread, you must be as close to the router as possible!
Chances are that your network is having some difficulties, resulting in issues with the Wi-Fi.
If that’s the case, there are multiple ways you could aid the connection of your network, by performing simple tasks for your Network Setup and Device.
This way, you’ll improve the connection that goes into your router and the state of the Wi-Fi thread.
Follow these steps to fix your network’s weak signal:
- Power Cycle – Unplug the Network Device for 5-10 minutes to discharge it
- Reconnect the Coax – Unplug the internet cable from your modem for 60 seconds
- Reset the Router – Press the “RESET” button on the back of your router
- Fix power issues – Plug your router into a different outlet and replace the adapter
Once you’re done with all of the following, test the Wi-Fi Calling on your mobile device.
However, make sure that your mobile is still connected to the network device’s Wi-Fi!
Alert: If you’re having network issues on other devices, contact your ISP!
The ultimate solution to issues with cellular, Bluetooth, Wi-Fi and all types of wireless connections is to Flush/Reset the APN Settings.
Those are the settings that your device uses when exposing itself to the public, meaning hostname, DNS and other…
Follow these instructions to reset the APN (Network) Settings of your device:
- Navigate to Settings.
- Go to “General” or for Androids, “More”.
- Choose “Reset”.
- Select “Network Reset”.
- Press “Reset Network Settings”.

It may take your device 3 – 6 minutes to undergo a complete network reset.
After that, all of the included settings that have been impacted by the reset will have factory values.
Alert: The Network Reset will result in permanent connection data loss!
