Yes, Verizon. To be honest, I have not been able to use the modem they supply because UPS made a mistake and ship it back to them. All I do know, is that some people have had trouble using SP2 with the versalink. The upgrade is definetly a huge difference! You will not be let down. I must warn you, when you get switched over, your data path will be switched to Interleaved, meaning higher pings Overall, service is great!
