My fiance's birthday is coming up in 2 months and I am looking to arrange her a surprise birthday party. I have her friends phone numbers, and am looking at sending out a text message to them about this. I however obviously don't want her to know about it, the problem I run into is that if I use my standard text messaging then she can go on verizon.com and see who I texted and she will recognize the phone numbers. Is there an app that I can download where I can text these people and not have it show up on my verizon account at all? Thanks.
