I purchased a tablet through Verizon & they said I needed a phone # to be able to get WiFi. Not true. Verizon charged me $20/mo for the phone # but they never activated the #. In the end I paid $480 to have the right to buy a tablet that only cost $380. This was not disclosed up front other wise I would have paid cash for the Tablet.
Make sure you understand your charges up front.
