Certain error codes are incredibly common and can be easy to troubleshoot, but it doesn't feel that way when you don't know what they mean. Here's a quick guide to the most common error codes that we come across (and the ones you've asked about the most), what they mean, and what you can do about them.
Error 67
This is by far the most searched error code by you, the customer, and the most talked about in calls to our support team. Luckily this is also a really easy one to fix in most cases.
What's Going On: Your 3G credentials aren't able to register with the network. Error 67 is a data issue
How to Fix It: To fix this issue, you can reset the network settings by dialing ##72786#. You can also update the data profile by pressing Menu-> System Settings-> System Updates-> Update Profile-> OK.
If you've got a data device then you'll need to run the profile update through the user interface online if there's no option to do it on the device itself. If you're not sure how to do that, just call our Customer Service at844.623.7827
Error 16
A solid runner up to error code 67.
What's Going On: Your device's network registration information can't be validated.
How to Fix It: You may have to do a full reset on your device. If you're not sure how to do that, just call our Customer Service at 844.623.7827
Error 6
What's Going On: As opposed to the network not being able to parse the information your device is sending, your device isn't connecting to the network at all.
How to Fix It: You may need to run a factory reset to fix this.
If you're not sure how to do that, just call our Customer Service at 844.623.7827
Error 129
What's Going On: This indicates that your data session has failed and is usually caused by a network outage.
How to Fix It: Just give it another try.
Error 131
What's Going On: Your device's data profile information isn't correct.
How to Fix It: Run a profile update and if that doesn't help, then try a carrier reset. If you're not sure how to do that, just call our Customer Service at 844.623.7827
Error 407
What's Going On: Your device's network access identification information has become corrupted or damaged so your device can't be authenticated on the network.
How to Fix It: Run a carrier reset. If you're not sure how to do that, just call our Customer Service at 844.623.7827
Error 600 & 601
What's Going On: This is a communication error generally related to LTE data.
How to Fix It: Disable LTE on your device (switch to CDMA only) then run a carrier reset. If you're not sure how to do that, just call our Customer Service at 844.623.7827
Error 1012
What's Going On: This can be a few different things including the network being busy, your device not being properly or completely activated on the network or your device's MSID not being correctly programmed.
How to Fix It: Try updating the profile and if that fails, remove/replace battery and then try the update again. Generally, once the profile is updated...that will prevent 1012 from happening...and then you can try to update the firmware. If it still doesnt work wait an hour or two in case it's a network congestion issue.
Error 2126
What's Going On: This usually means there's a problem with the sync between your device and the network.
How to Fix It: Run any updates to your phone if applicable, and then power down, pull your battery for 30 seconds and then replace, reboot. Your problem should be solved, if not, call your customer support. We'll probably need to do a carrier reset, but we'll want to toggle your settings on our end first.
