Fix Phone Not Allowed MM#6 Error 

Contact the Carrier 

A carrier refers to a wireless service provider offering cellular connections. Mobile companies partner with these carriers to get EMI schemes.

As stated earlier, this is the fastest solution to your present issue. While there is no guarantee that the issue will get solved immediately, this should be your first try.

You may choose to use their toll-free lines or send an email to customer service giving all the relevant details about your issue.

However, this step can get complicated especially in these situations;

If you are handling a stolen or blacklisted phone, they might need you to meet certain requirements before they can honor your request.

The carrier may choose to charge a fee known as the “Equipment Switch” and for others, the phones have a linked phone number. In this case, it will be difficult to get it unlocked.

Check SIM activation status

If you are experiencing this error on a new sim card, give it some time before trying again. A new sim card takes between 24 to 48 hours for activation.

To know more about the activation process, contact the carrier of the SIM card of choice. You will be asked to verify your identity for the operator to confirm details about the SIM card.

Use the Operation Menu

If customer support doesn’t get the issue sorted within your preferred period, this issue is fixable through dialing the short code: *#78# which brings you to an operation menu.

Doing this disengages you from the carrier and simultaneously unlocks your phone. Important to note though is that this method is limited to some carriers.

So, do your research around your specific phone model, brand, carrier, and its suggested options for unlocking.

To do this, first, select the settings option on your device and click on data usage. Select Mobile network and then click on the automatic option when asked for sim card preference.

Then restart the device to check for recurring or solved errors.

It could be that the software in the device is obsolete. To fix this, you must conduct a software update. Select the setting option and click on the device option and click on software update.

Check for an available device update and if there is one, proceed on to update the phone. If the process itself does not initiate phone restart when complete, ensure you do so manually.

Then confirm if the error is gone.

Check IMEI Number 

This number carries important data about your device and this is what helps network providers with the right details to track or remotely shut it off if reported lost or stolen.

It is important to know your IMEI number especially if you are thinking of changing your network provider or selling your device.

In fixing the MM#6 error, this is the number that will guide you in the right direction in terms of figuring out which carrier you are locked to.
