The MIP 67 error pop-up can appear on Tablets and Android mobiles of any brand like LG, Motorola, etc. In this article, we have defined MIP 67, and we have also explained why it occurs and how you can fix it. It does not matter if you are using Boost, Sprint service, or any other cellular network, the steps for fixing the issue are the same. 

MIP 67 Meaning and the Reason Behind the Pop Error

The MIP 67 is a mobile node authentication failed error that can pop-up when the device fails to register with the (Packet Data Serving Node) PDSN (a component of the carrier’s network.) In simple language, the MIP 67 error usually occurs when your device cannot access cellular services like mobile data. 

The pop-up can occur because of multiple reasons, including incorrect provisioning. Sometimes the MIP 67 error pops-up when you activate a new device with your same old sim card and phone number. It can also pop up if you have a sim card installed with no service and your mobile data is on. 

How to Fix MIP 67 Error?

There are multiple methods for fixing the MIP 67 error; we have tried to cover all of them. If you are someone who is facing this issue on a device you want to use with Wi-Fi only, you can put your device on airplane mode to avoid the MIP 67 pop-up and normally use Wi-Fi. For those who want to fix the issue, the methods are mentioned below:

Method 1) Turn off Mobile Data and Turn It on Again

Turning off the mobile data will 100% stop the pop-up since the device will not attempt to check for cellular services, but the point here is to fix the issue, not just avoid the pop-up. Once you turn off mobile data, turn it on after a few seconds. If it does not work, you can try removing and reinserting the SIM card.  

Method 2) Restart Your Device

Sometimes restarting the device can fix issues like this, and it hardly takes a minute to restart your device, so make sure you try this. Most devices can be restarted by just holding the power button for a few seconds and then tapping on the restart button. Once your device turns on, hopefully, you will be able to access all the cellular services and not see the pop-up again.

Method 3) Change the Network Mode

Settings> Connection > Mobile networks> Network mode> select LTE/CDMA.

Once you are done, go to Settings > General > System Updates > Update Profile. 

If the wrong network mode was causing the issue for you, it will not pop-up again.

Method 4) Update the Device’s Preferred Roaming List (PRL)

Preferred Roaming List (PRL) is a database stored on CDMA devices; according to Wikipedia, it contains information used during the acquisition procedure. Occasionally updating the PRL is recommended to receive excellent service, and if you are dealing with the MIP 67 pop-issue, this method can fix it sometimes. 

Before you follow the steps mentioned below, you need to make sure your device is connected to Wi-Fi.

1. Open Settings.
2. Scroll down and tap Software update.
3. Tap Update PRL.
4. Once it’s done, tap OK.

or

1. Call *228.
2. Select 2 to update your phone’s PRL. 

After a couple of minutes, you should see a confirmation message.

Method 5) Change MSID (Mobile Station ID)

Using the wrong MSID (Mobile Station ID), also called MIN (Mobile Identification Number), can prevent your device from using cellular services, which will eventually trigger the MIP 67 authentication error. 

You need to contact the customer support of your service provider and ask them for your MSID; once you get it, follow the steps mentioned below:

• Open the dial app and dial ##847446#, and tap Edit.
• Enter the MSID provided by the support team and tap OK. 
• The handset will reboot, and you should stop seeing the MIP 67 pop-up.

What to Do If Nothing Works?

If you try all the methods and none of them fixes the issue for you. There are some more things you can try that might work. Below we have explained some solutions like factory data reset, ensuring your service provider has the correct ESN number, and more. 

1. Try dialing ##72786# using your phone, this will reboot your device, and in some cases, it fixes the MIP 67 error. 
2. Call the customer support team of your service provider and check if they have the correct ESN and sim number.
3. As mentioned multiple times, MIP 67 occurs when your device fails to get mobile data, so if your phone has a SIM card without any service plan, remove it; additionally, you can also check for service outage in your area.
4. When nothing works, factory data reset does. Factory resetting your phone will restore it to its original state by erasing all your stored data; this is why we recommend you backup your data before resetting your phone. 
5. The last thing you can do is use Wi-Fi; we understand this is not what most people want, but if no method is working for you (which is super rare), you can remove the sim card from your phone and connect it to Wi-Fi.
