Part 2: How to Fix Phone Not Allowed for Voice in 13 Basic Ways

Fix 1: Reinsert SIM Card

Before reinserting your SIM card, first check its status by ensuring it's active, properly registered with your carrier, and not damaged or expired. Power off your phone, remove the SIM tray, gently clean the SIM card, and place it back securely in the correct position. Then restart your device and check if the "Phone not allowed for voice" issue has been resolved.

Fix 2: Toggle Airplane Mode

• Turn on Airplane Mode for about 20 - 30 seconds to disconnect all network signals.
• Then turn Airplane Mode off to force your phone to reconnect to the mobile network. This quick reset can help restore voice service if the problem is caused by a temporary network glitch.

Fix 3: Verify Device compatibility with the Network

Start by confirming that your phone is officially supported by your carrier, since some devices cannot access voice services on certain networks due to incompatible frequency bands. You can compare your phone's supported network bands with the information provided by your carrier or the manufacturer's specifications. If there is a mismatch, the device may not be able to place calls, resulting in the challenge.

Fix 4: Reset Network Settings

• Open your phone's Settings and navigate to System or General Management, where you will find the reset options menu.
• From there, tap Reset Network Settings to clear all saved network configurations such as Wi-Fi, mobile data, and Bluetooth connections.



• Once the reset is finished, reboot your device so it can establish a fresh connection to your carrier.

Fix 5: Check Call Barring Settings

• Open your Phone app settings and go to Call settings > Call barring to check whether any outgoing or incoming calls are restricted.
• If call barring is enabled, turn it off to restore normal voice calling and fix the error.

Fix 6: Reset APN Settings

• Go to your phone's Settings > Mobile Network > Access Point Names (APN).
• Select the option to reset APN settings to default, which will restore the correct carrier configuration automatically.
• After resetting, restart your phone to ensure the new settings take effect and reconnect properly to the network.

Fix 7: Inspect device locks

Start by checking whether your phone is carrier-locked or IMEI-blocked, since either restriction can prevent voice service from working. You can do this by inserting a SIM from a different carrier or contacting your network provider to confirm the lock or blacklist status. If a restriction is detected, you'll need to request an unlock from the carrier or resolve any account/IMEI issues before voice services can be restored.

Fix 8: Check IMEI Status

IMEI allows for phone unlocking free. To check IMEI status and fix the "Phone not allowed for voice" issue, first dial *#06# to display your phone's IMEI number. Then contact your carrier or use an official IMEI check service to confirm whether the device is blacklisted, blocked, or reported lost/stolen. If the IMEI is restricted, your phone will not be allowed to use voice services until the carrier resolves or removes the block.

Fix 9: Dial Unlock Code

This method only works on certain carriers and devices, so if nothing happens, you'll need to contact your carrier or try another fix. To do this:

• Open your phone's dialer and carefully enter the carrier-specific unlock code (commonly something like *#78# if supported).
• If your network supports it, the phone will process the request and remove the voice restriction after you confirm the prompt.

Fix 10: Check for Software Update

• Go to Settings > Software Update and check if any system updates are available.
• Install the latest update to fix possible bugs affecting network and voice services.
• After updating, restart your phone to apply changes and restore normal calling functions.

Fix 11: Check Network Operator Settings

Open your Settings > Mobile Network > Network Operators and turn off "Select automatically." Once the list of available carriers appears, manually choose your correct network operator instead of leaving it on auto selection. After selecting it, wait a few moments for the phone to reconnect and register properly on the network, which can restore voice service.

Fix 12: Boot into Safe Mode

• Press and hold the Power button, then long-press Power off until the Safe Mode option appears and tap it to restart your phone.
• In Safe Mode, your device runs only system apps, which helps you check if a third-party app is causing the issue.



• If voice services work normally in Safe Mode, uninstall recently added apps and restart the phone to return to normal mode.

Fix 13: Contact Carrier Operator

Contact your carrier's customer support and report the "Phone not allowed for voice" error. Provide your SIM details and IMEI so they can check for any account or network restrictions. The carrier can then unlock, reactivate, or fix any issues blocking your voice service.
