So my mom has the 4g iPad and has been loving it for the past few weeks. We got her the 4g verizon version so she has the option of adding 4g later on if she needs it. So now she told me she wants to add that funcionality and I just wanted to know how exactly does this process work? Do we take the iPad in and they put a sim card in it? How does this no-commitment thing work? I wonder if we can call verizon to activate it? Thanks everyone!
