Method #1: Contacting Customer Service

Contacting the carrier of your locked phone should be your top priority as they can help you unlock your device. However, don’t get your hopes up, as this method is not a sure-fire way. Since we have established the success rate of this method, let’s continue with the method itself.

Find Your Phone’s IMEI

Before you decide to call customer service, knowing your phone’s IMEI is crucial. Every carrier out there uses your phone’s IMEI to track it. Only after that can they even try unlocking your phone. To find your phone’s IMEI, just follow the steps below, and you will be good to go.

  1. Go to your phone’s keypad.
  2. Dial *#06#, and a window will pop up with your IMEI.

If you have the box of your phone lying around, you can simply check the back of your box. Your phone box always contains the serial and IMEI numbers of your device.

Call Customer Service

Now that you have the IMEI number for your phone, go to your carrier’s website and look for their customer service number. Once you have their customer care representative on the phone, tell them about your problem. After which, they will ask you a series of questions, including your phone’s IMEI. If they think your answer checks out, they will unlock your device.

Info

Contrary to proper belief, unlocking your phone is legal in the US. If you are planning to unlock your phone, contact your carrier, and they will help you unlock it.

Method #2: Using Third-Party Software 

Using third-party tools to unlock your carrier-locked phone is so easy that an average Joe can do it in a matter of minutes. All you need to do is download the recommended software for your device. For this guide, we will be using the iTool Lab SIMUnlocker. However, you can use any other software that you prefer.

Sometimes the culprit behind the MM#6 error isn’t your carrier but the faulty network settings. If you are trying to reconfigure your network settings manually, it can be a real pain. However, you don’t have to deal with reconfiguration, as resetting your network settings will suffice.

Since you will be resetting your network settings, try backing up all your WiFi settings beforehand. Once you have backed up all your network settings, go through the following steps to reset your device network settings.
