This question is basically for the majority of people who have a cell phone with unlimited minutes/text and a shared data plan. (Basically the way verizon and at&t cellular are set up)

Question: Do any of you have a SIP mobile voip app on your smartphone? If so; why?

Caveats:
1. If you travel out of the country or often in areas where your "Cell Phone" is useless, but you can get a WIFI connection, a VOIP softphone app would be convenient
2. If you are on an old cell plan or a pay as you go type plan where you don't have unlimited talk minutes, but you can get a WIFI connection, a VOIP softphone app would be convenient

So, the question is for anyone who has the more commonly used "Family" type or similar cell phone plans where you share data, and you have UNLIMITED talk and text. Do you use a voip mobile app either on your smart phone or tablet? And if so, WHY - if you have a cell phone, with coverage, and unlimited minutes.

Just curious. Thanks. Mike.....
