Charges for conference call numbers


    I am a new T-Moble customer as of August.  Today I received a rude shock when I learned that some conference call phone numbers (in the US) are "out of plan" and that T-Mobil will charge me extra to make what have been routine calls with other carriers.  For a plan that is advertised as covering all of the US, Canada & Mexico this seems like a "bait & switch" policy.  Does anyone else object to this?
