Got my phone activated yesterday after waiting a week for my SIM. Was using my FreedomTalk VoIP minutes on my Nexus to talk to support so when they said to reboot and everything should be set, i just hung up on them and rebooted. Everything worked but data. Gave it a day, still no go. Called and they said we needed to manually reprogram the phone...so I needed to call back from a different phone (not possible at the moment). I told him I couldnt and he said to shut down, turn on after 60 seconds, update PRL and Profile, and see if that works. Obviously it did not. After much Googling I found this article on ROK's own site and it resolved my issue of not having data services.
Follow that and boom, data will start working immediately.
