I have been looking into 3rd party text apps that I could use on my tablet. My tablet has no data plan but I often want to text with my mobile phone number from my tablet. I have been using Viber for a few weeks and it works well for the most part but does have a few things that I find annoying. Mainly that everyone you text has to also have Viber installed and that it's a social app.
