serious issue with roaming please HELP!!!!!

[kronik420]

I'm having a serious issue with roaming I live in central florida and in some areas the sprint service suck. I'm currently running the latest fresh rom as well as the latest klick kernel I have tried also stock kernel same thing. Currently have flashed pri 1.77 and I also had pri 1.43 and the same problem happened. When ever I try to make a call and if I'm in an area where there is no signal and I have to roam. Usually it is verizon towers when I call it says that you for calling verizon we are sorry we cannot authenticate your phone please call verizon customer service. If I try to call again several times it will actually xfer me over to an operator for verizon and ask me if I'm placing an international call. So I can not roam onany network because my phone can not be authenticated has anybody had this issue. Thank you please any help or adivse I would greatly apperciate thank you
