Hey all. I'm really new to android and I have some questions. I have the optimus net from net10. As to my understanding, it runs off Sprints towers, but sprint has a contract with verizon so that they can roam on verizon towers. Can my phone roam on verizon towers? I notice that my data icon and bars are sometimes white instead of green. Does this mean my phone is roaming? Thanks in advance guys.
