I use mine on Verizon, I had to use an IMEI number from an Apple IPad to register the SIM card, then the Verizon guy installed it and it worked fine. My buddy worked with Verizon as well, did t have a tablet to borrow an IMEI against, but they figured out the manufacturer and SKU number and the Verizon rep loaded it in the Verizon data base so it should be good now.
