I purchased this item on line and when I put it in my phone (LG Env2), it simply didn't work correctly.  It worked off and on and then my phone was giving me confusing error messages about it.  I had had no previous problems with my phone.  I kept playing with it, thinking I was doing something wrong.  I finally brought my phone with the card in it into Verizon.  They tried it in a few different phones, and told me that the card didn't work correctly.
