I recently purchased a used Galaxy Nexus. I previously had a Thunderbolt and I knew that the SIM card would not be compatible. I went down to the Verizon store on Monday and got a new SIM card. Everything seemed great. Phone connected and I had data without any issue. When I got home I went to make a phone call and I received message telling me basically I would be directed to an outside network to make a phone call. I called Verizon CS and they told me sometimes it takes a while for a card to fully activate. I tried again yesterday to make a call and had the same thing happen. I called Verizon TS again. We did a factory reset, etc. That made no difference. I'm grateful I have data, but I also need to make phone calls. I'm going to go to the Verizon store today at lunch to get yet another SIM card, which is what Verizon recommended I do. While I'm in the store I'll do a factory reset and see what happens. Has this happened to anyone else? Is there anything else I can do other than going back to the store for another SIM card. I mean I just got a new one on Monday. I appreciate any help or feedback.
