My brother purchased a Slingbox and he currently uses and will continue to use Verizon FIOS in his home. He is planning on being away in the winter and will be staying in a place with no internet access but he will have his iPad Air with him. He wants to view ESPN and wanted to use the Slingbox. He is not that computer literate and asked if I would check on it. I am puzzled by a Slingbox. If this is considered streaming does that mean he will then incur charges on his wireless plan and do you have any idea how much gigabytes he would use. I am not very computer literate myself but a wee bit better than him. Thank you.
