This may be a silly question , but bear with me I'm over 60 …..I plan to take my tablet on the CF (leaving Sept.2nd) and use it to take a daily picture to post to my Facebook family. Question: do I need to buy something in Spain (similar to a new SIM card for a phone) for the tablet? Or can I just use a free WIFI spot and get on line and post the picture to Facebook? Can I also use Google, Twitter, or my email free on the tablet at a free WIFI spot? Thanks!
