WiFi on the Go is a VIP program for student families and employees of our partner school districts. T-Mobile has asked us for a way of validating eligibility for the program and that is what the id numbers are for. The system actually matches what you put in with what is in our database to conduct that validation. If it is a match, the system lets you right on through. If not, you may get an error message. Don’t know it and can’t seem to make it work? Don’t worry, we can help or you can contact your school to get the number.
