Well i got the 9.99 web2go plan for my iphone 3g 20 minutes ago...it said wait 24 hours, should i just start using it now or will it charge? lol sorry i know im a newb
They can't charge for what's not active on the account. The "up to 24 hours" is the time they give themselves to actually turn on the data service. So keep testing it until it's on.
