How to Fix ‘Phone Not Allowed for Voice’ Issue

Fixing the “phone not allowed for voice” error requires applying targeted methods carefully. The following section covers the top 11 ways to help you address and resolve this problem:

1. Restart Your Device

The first and quickest solution is to restart your phone to resolve the “phone not allowed for voice” issue. This method clears small glitches and refreshes the system to restore the normal working of features like calling. Review the quick instructions below to find out how you can perform this solution:

Step 1. Keep pressing the “Power” button for a few seconds and tap “Reboot” to restart your phone.

Step 2. Once your phone is restarted, your problem will be resolved successfully.

2. Check Network Connection

The “phone not allowed for voice” problem is also caused by your signal being weak or irregular. At this particular point, look at the signal bars icon at the top of your screen. A single or two bars are either an indication of having poor coverage or No Service. Relocate to a place that has a stronger signal, like outside or beside a window.

3. Check Network Operator Settings

This solution focuses on altering your network settings and ensuring smooth connectivity for calls. It helps users reduce dropped calls to improve clarity and keep voice services working without interruption. By switching to stronger coverage areas or enabling automatic network selection, users can restore proper communication.

This clears all saved mobile data and Bluetooth settings to help you fix any connection problems. It also allows your phone to reconnect properly to the network and improve call quality or stability.

Step 2. In the Reset section, tap “Reset Network Settings”, and then hit the “Reset Settings” button to confirm.

5. Reinsert SIM Card

Sometimes “phone not allowed for voice” issues occur because the SIM card is not properly connected. You can refresh the connection between your phone and the network each time you turn your phone on and take it off. Moreover, this will help in getting the SIM right, and the phone will feel the network right. In addition, it restores normal voice functions without complicated troubleshooting.

6. Try a Different SIM Card

Apart from reinserting, you can also try to insert a different SIM card when facing the “phone not allowed for voice” problem. It assists in finding out whether the issue is with the existing SIM card, such as becoming damaged or having problems with the network. In addition, a voice service can be restored to use with a different SIM in case the initial one is invalid or expired.

7. Check Account Status with Carrier

You also need to check your account status with your carrier when facing the “phone not allowed for voice” issue. Carriers sometimes block calling services because of unpaid bills or even account suspensions. Verizon, AT&T, and T‑Mobile users can check balances using apps like MyVerizon, myAT&T, or T‑Mobile. Additionally, try carrier codes such as *777# for balance, or *#06# for verifying device IMEI status immediately.

8. Confirm Device Compatibility with the Carrier’s Network

Device compatibility is vital because not all phones support every carrier’s required network bands. If unsupported, your phone may show the “phone not allowed for voice” error during calls.

Step 1. Navigate to the “Settings” to access “About Phone” and tap the “All Specs” option.

Step 2. Choose the “Status” option and put your “IMEI” number in any Compatibility Checker online.

You can test this by inserting a SIM card from a different provider. If it shows “SIM not supported” or “network locked,” your device needs unlocking to restore proper calling access smoothly.

10. Check for Software Updates

As a final basic solution, you can now check and update your software version to resolve”phone not allowed for voice”. Network issues may occur if your phone is not updated, causing dropped calls or no voice service. Along with that, updates fix other bugs that affect network or voice services and improve stability.
