Facing the “phone not allowed for voice” error can be exasperating, but did you know that sometimes, it’s just a matter of unlocking restrictions placed on your device? Indeed, a phone locked to a particular network can throw up this error if you insert a SIM card from a different carrier. A straightforward solution? Dialing in the unlock code. Let’s dive into this remedy.

Dialing The Unlock Code to Fix Phone Not Allowed for Voice Error

Phones purchased under certain contracts or offers are often “locked” to a specific carrier. This means they won’t work with another service provider until they’re unlocked.

Obtaining the Unlock Code

  1. Contact Your Carrier: Your first port of call should be your service provider. They can provide the unlock code, especially if you’ve met their unlocking criteria, which might involve completing a certain duration of your contract or paying off your device in full.
  2. Third-party Services: There are numerous reputable online platforms where, for a fee, they’ll provide an unlock code for your device. Ensure you’re dealing with a trustworthy service to avoid scams.

How to Dial The Unlock Code

  1. Insert a Different SIM: Begin by inserting a SIM card from a different carrier. This prompts the device to ask for an unlock code.
  2. Enter the Code: When prompted, enter the unlock code you’ve obtained. This should be done cautiously; excessive incorrect attempts might permanently lock the device.
  3. Confirmation Message: Once the correct code is dialed in, a confirmation message typically pops up, signaling the phone is now unlocked.
  4. Restart Your Device: Give your device a quick restart. After booting up, it should now connect smoothly to the new network, resolving the “phone not allowed for voice” error.

Things to Keep in Mind

  • Always ensure the unlock code is accurate. Erroneous attempts can lead to permanent locks.
  • Before purchasing an unlock code online, read reviews to confirm the legitimacy of the service.
  • Understand your carrier’s terms and conditions. Some may charge a fee, while others may unlock for free after certain conditions are met.

Factory Reset

There’s something almost magical about a fresh start. In the world of tech, the ultimate fresh start is the factory reset. Encountering the pesky “phone not allowed for voice” message? Before you toss your phone in frustration, consider this option.

Before you proceed with a factory reset:

  • Backup your data: Make sure to back up any important files, photos, contacts, and other data to a safe place, like your Google account, an external storage device, or a cloud storage service.
  • Charge your device: Ensure your device has enough battery power to complete the reset process, or keep it plugged in during the reset.
  • Remove SD and SIM cards: If your device has external storage such as an SD card, it’s a good idea to remove it to prevent accidental data loss.

Here’s how to perform a factory reset:

  1. Open the Settings app on your Android device.
  2. Scroll down and tap on “System,” which you may find at the bottom of the Settings menu. In some versions of Android, this may be under “General management” or similar.
  3. Look for a submenu that says “Reset,” “Backup & reset,” or “Advanced options” and tap on it.
  4. Tap on “Factory data reset,” “Erase all data,” or “Reset phone.” The exact wording will depend on your device.
  5. You will likely see a list of the data that will be erased and may have the option to also wipe data from the memory card. If you’re sure you want to proceed, tap on “Reset phone” or “Erase everything.”
  6. If you have a lock screen set up, you may need to enter your pattern, PIN, or password.
  7. Confirm your choice and your device will begin the reset process. This might take a while, and your device may restart multiple times.

Important considerations:

  • After a factory reset, all data that has not been backed up will be permanently deleted.
  • If you are disposing of your device, it’s a good idea to encrypt your data before performing a factory reset. This way, even if some data is recoverable, it will be unreadable.
  • If you’re performing a factory reset to troubleshoot your device, it might be useful to restart your device in recovery mode and wipe the cache partition before doing a full reset.

For devices with Android 5.1 or higher:

If your device has Android 5.1 (Lollipop) or higher, it may have Factory Reset Protection (FRP). FRP requires you to enter the Google account details that were set up on the device post-reset. Ensure you know these details before resetting the device, or you could be locked out.

If you’re unable to access the settings menu for any reason (e.g., the phone is non-responsive), most Android devices also offer a way to perform a factory reset using physical buttons by entering the device’s recovery mode. This process varies by device, so you may need to look up instructions specific to your device model.

Contact Your Service Provider:

They can offer insights into potential network restrictions, blocklisting, or other specific issues related to your account or device.
