Why your internet does not work when you are on a call?

You might not be able to surf the internet while you are on call for the following reasons

Phone Restrictions

Some phones are made without the feature to allow voice and data simultaneously. Due to this restriction, your internet connection is usually blocked until you end your call. Your internet connection resumes automatically after your call.

Incorrect APN configuration

To support both internet connection and call at the same time, you must ensure that your Access Point Name is set to be LTE. It is possible that the default Access Point Name of your network is not LTE, if this is the case, you cannot browse while you call.

CDMA-based networks

If your carrier’s network is built on an older CDMA version, you cannot surf the internet while you are on a call. This is because voice and data connectivity is not supported to function simultaneously.

VoLTE status 

In case you use a 4G LTE network, if your VoLTE is off, your internet connection will automatically be disrupted because the call will change the 4G to either 3G or 2G.

How to use the internet while on a call with another sim?

This applies to devices with dual sims. Some android devices come with a feature that allows you to receive calls on a sim while browsing on another sim. To illustrate, if you are using line 1 to surf the internet, and a call comes in on line 2, you can receive your call but your browsing line will automatically turn to line 2. It is sweeter because, for android, only a sim is allowed to browse the internet at a time, this gives you the opportunity of browsing with the same line through which you are receiving your call. Follow the following steps to activate this feature:

From settings, go to connections or network & internet settingNext, click mobile settingsToggle ‘Allow All Sims to Use Data In Calls’

The world is at a point where we should be able to receive calls without disrupting our internet access. This feature is now in phones. All you have to do is to visit your settings and toggle any necessary options.

Q: Can I use the internet and still receive calls simultaneously on my iPhone?

A: Yes, you can access the internet and still receive calls on your iPhone by enabling voice and data under 4G in your phone settings

Q: Can I receive a call and access the internet on a 2G/3G phone?

A: No, you cannot. Unless you have a 4G LTE, you cannot use the voice and data feature.
