Yes, calls and texts are not included with tablets on the Verizon network. You can use Skype or a similar app to make calls, though. These apps will use data, though. For texts, you can install Verizon Messages to access your text messages. This app will ALSO use data.
Are you sure you are paying more??? The smartphone access fee is $40/month. The basic phone access fee is $30/month. The tablet access fee is $10/month. How do you figure you are paying MORE for this device???
