It says my serial number is invalid. What do I do?

First, double check that you are inputing the serial number correctly. Note that if your first number is 0 it is a zero and not the letter O. If it is still invalid, there is likely a system issue on our end. Please reach out to our team with a picture of your serial number so that we can update our system and make sure you can activate your hotspot. Sorry for the inconvenience.
