Hello all, Ordering a iPad mostly for home use although I would be taking it out now and then but not religiously (maybe 1-2 times a month). When at home it will be running of my wifi, but I dont mind paying the extra to get the 3g version for when I'm on my travels. My question, these PAYG sims are they like a normal phone one? If i top up £10 could that £10 last me a few months/year if 3g is used very rarely, or does the PAYG have to have a minimum top up each month. Or maybe on another note does the 3g version get to see much 3g access? With most places these days wifi connected? As said I don't mind paying for the wifi +3g but is it worth it in the long run? Will 3g die or grow in the next few years? Sorry for all the newbie question, Hope I get some useful feedback Cheers.
