It seems that no one can get the GoPhone Prepaid Unlimited Plan to work with a smartphone with unlimited data - and that one of the data packages is required - i.e. $25/500MB. 1. What would be the difference between the following options? [$25/month voice plan + $25/500MB data package] versus [$35/month No-Commitment 3GB Data Package (for Tablets) + Skype Number/SMS] 2. The main (questionable) assumption I know that I'm making: - The Tablet Data Package will work in a smartphone (in my case, possibly an unbranded GS2 from China). Anyone know if this will work? I travel abroad a lot - so I am particularly interested in economical prepaid plans. I already have a Skype account (with a phone number + unlimited US calling) for use when I'm out of the country. Thanks!
