Who I have the same questioned this topic

Earlier this year I started getting a message that I am now Roaming and need to purchase a pin in order to make a call. It is happening in extended network areas.  I have never had these problems.
My family members are part of the same plan and do not have the problem. A few weeks ago I was on a call with tier 2 at Verizon and the problem was not resolved. Today I did a factory reset and still have the same problem. When that happens I restart my phone and it fixes it for a few minutes and then then goes back to Extended Network and I cannot make or receive a call.
