When you call someone it displays your Google Voice number. When someone calls your Google Voice number it forwards it to the Skype number and the Tab rings. If you use Google Voice for SMS it does not do MMS Price for this to work per year amounts to $66 ($30 for the Skype number and $36 for the unlimited plan) Not really a con if you consider this is the total cost for a year of unlimited cell (VOIP) calls from you Tab

The one that came on your Tab that is used for SMS/MMS and a number for phone usage. Skype for Android 3.0, released on Tuesday, has been built. If you don't want to use the Google Voice number for SMS then you will have 2 numbers. Skype has redesigned its Android app to work better on tablets, but some users are complaining that the update is affecting performance. Use Google Voice for SMS messages and you only have the one number.

With 3G data plan you always have phone functions to dial out and receive Unlimited calling in the US and Canada for $2.99 a month Incoming and outgoing voice capabilities Go into Google Voice App and set it up to use your Skype number for voicemail notifications. Set Google Voice to forward all calls to your Skype number Set Skype to display your Google Voice Number (Caller ID Settings) Add a Skype calling plan ( I went with $2.99 a month for unlimited calling) Order a Skype Internet Number (it's $30 for a year right now - normally $60) Get the hacked Skype App (allows 3G calling)

I now have a working VOIP phone service via my T-Mobile Tab.
