I signed up on my computer an account for internetcalls.com. on there site it says I get 300 free* minutes a week. I connected the sip account for it onto fring to use it on my ipod touch. I just want to make sure theres no hidden fees or something. its awesome that I can call with my ipod touch now so its like an iphone, but if somehow my mom gets bills for it she will be pissed. I didnt have to put a credit card or anything in, so I think it should be completely free. Am I right?
