Toll free is just that, the Toll aka the Long distance portion of the charges are waived and the receiving party pays that, airtime is not reflected in that. but if you are on a plan that has airtime charges, you are subject to your per minute rate for those calls just like you would experience making local calls, no difference. Same with making calls outside of your local area, if you are from toronto and travelling to hamilton and making a call, your calling a 1800 number, you "might" get additional airtime charges from your wireless carrier cus your "outside" of your local area, these are not the same as long distance charges but billed usually at a similar or the same rate. if the number your calling has a * number available, then those generally do not have airtime charges,. so *OPP, *1010, *611, etc. those are completely free, (from canada, but once you leave canada they might be charges) its always best to ask your provider and give us a proper explanation,. were you in your home area, where you visiting another area, was it an acutal toll free number?
