Mobile Data Not Working During Calls on Android? Here’s the Fix!

Mobile Data Issues

🔍 Introduction

Ever noticed that your mobile data stops working when you're on a call? You're not alone. Many Android users face this frustrating issue, especially during video calls, browsing, or using internet-based apps like WhatsApp or Google Maps while talking on the phone. But why does this happen, and how can you fix it?

In this guide, we’ll break down the reasons and give you simple step-by-step fixes to get your data working again—even while you're on a call.

❓ Why Does Data Stop Working During a Call?

The issue usually comes down to network limitations or phone settings.

Here are the common causes:

1. 🧭 Single SIM + Non-VoLTE Network: If your phone doesn’t support VoLTE (Voice over LTE) or it’s turned off, your device switches to 2G/3G during a call—which may not support data.

2. 🔌 Poor Network Coverage: Weak signal strength during calls can cut off your mobile data.

3. ⚙️ Incorrect SIM or Network Settings: Sometimes the wrong APN or network preference can block data.

4. 🧪 Software Bugs or Carrier Restrictions: A bug in the OS or carrier-specific limitations can also cause this issue.

🛠️ How to Fix 'Data Not Working During Call' Issue in Android

Let’s troubleshoot step by step:

1. ✅Enable VoLTE on Your Phone

   
   

   VoLTE lets you use 4G data during calls. Here’s how to enable it:

Steps:

• Go to Settings > Network & Internet > SIM cards

• Tap your active SIM > Turn on VoLTE or 4G Calling

• If the option is missing, your phone or SIM may not support VoLTE

📌 Note: Some phones label this as “Enhanced 4G LTE Mode”

2. ✅Set Preferred Network to 4G/5G

Ensure your device prioritizes high-speed networks.

Steps:

• Go to Settings > Mobile Network > Preferred Network Type

• Choose 4G/5G (Auto)

• Restart your device

3. ✅Check Dual SIM Settings

   
   

   If you're using two SIMs, make sure the correct SIM is set for both calls and data.

Steps:

• Go to Settings > Network & Internet > SIM cards

• Set the same SIM for both Mobile data and Calls

4. ✅Update Your APN Settings

   
   

   Outdated or incorrect APN settings can cause connection issues.

Steps:

• Go to Settings > Mobile Network > Access Point Names (APN)

• Select your SIM > Tap the correct APN from your carrier

• If unsure, reset to default or contact your network provider

5. ✅Use Wi-Fi Calling (Alternative Option)

   
   

   If VoLTE is unavailable, Wi-Fi calling can help.

Steps:

• Go to Settings > Network > Wi-Fi Calling

• Enable it and connect to a stable Wi-Fi network

6. ✅Contact Your Carrier

   
   

   If all else fails, contact your mobile provider to check for:

• VoLTE activation status

• Network restrictions

• SIM-related issues

🔄 Bonus Fixes

• 🔋 Restart your phone

• 🧽 Clear network settings cache: Settings > System > Reset > Reset Network Settings

• 📲 Update your phone software

• 📶 Try the SIM in another phone (to isolate the issue)

📌 Key Takeaways

The inability to use mobile data while on a call is usually tied to VoLTE settings or network type. Once VoLTE is turned on and your phone is on a 4G/5G network, you should be able to browse the internet, use apps, and stream media—even during calls.

With the above solutions, you’ll be back to multitasking in no time.
