Suddenly no wifi or text ability in northwest vegas

[shellvegas]

Hello, I've never had problems with Verizon or my iPhone but suddenly yesterday I was unable to text or have internet connection when I left my house (where I use our home wifi).  This has gone on now for two days.  Any ideas about what I may have done to my phone to make this happen?  I've checked my settings but might have missed something.  Thanks!
