"Unable to authenticate your phone" after flashing several roms

[eatbuckshot]

So for the past few days I've been flashing through many roms.
I tried vzw's 6.5 stock rom then some malroms, nrg's, and mightyrom. Up until mightyrom i believe i was able to call out, at least voice mail. But now I get an unable to authenticate your phone. I tried flashing back to vzw's 6.5 stock with both data and phone not working. I tried reprogramming, and that got data to work, but I still can't call out. Is my only option to call up vzw to reset it on their end? or could there be another issue that i can fix
