Our products are not locked to a particular cellular provider (carrier). You need a 2FF (Form Factor) Sim Card (usually given on a 1FF credit card sized card.) already activated, data only, no E911 services on it. You are free to choose your carrier. We are not a cell service provider; we are just providing the equipment to help you connect to Cellular 3G – 4G further than you otherwise could and share that to multiple users' devices onboard.
