Wondering – Why my Internet doesn’t work during call? Well, it can be a nightmare when the Internet won’t work during a call.

Luckily, we have all the information you need to get around the issue. Either you have an outdated Android version or incorrect phone settings.

You may not have updated your mobile OS, or your APN configuration may not be set to LTE by default. Another possible culprit is a disabled VoLTE.

Change your phone settings to get the Internet to work while you are on a call. Go to Access Point Names under SIM cards & Mobile Networks and set the Bearer to LTE. Reboot your handset and see if this works. If this does not work, check for new software updates.

Before we look at the fixes for your Internet not working during a call, let us discuss the possible reasons for the issue. Let’s get stuck into it!

Reasons Why My Internet Doesn’t Work During Call

If your Internet is not working while you are on call, it may be due to hardware restrictions.

Your handset may have a sole radio interface, which blocks mobile Internet until your phone call ends.

Other causes of the issue include:

1. SIM Issue

Your phone may support dual SIM. For instance, SIM1 is your data SIM, and someone calls you through SIM2. SIM1 will deactivate during a call.

2. VoLTE Not Enabled

If VoLTE is disabled, you can’t access the Internet during a call. Your phone switches from 4G to 3G or 2G, causing the Internet to disconnect.

3. Not Supported by Carrier

If your carrier network is CDMA-based, voice and data communication cannot work simultaneously.

4. Outdated APN Settings

Your phone uses APN settings to connect to the Internet. The bearer settings in the current configuration may not be set to LTE.

These are the main reasons your Internet is not working during a call. Now that you understand them, we can move on to fixing the issue.
