a. I would like to add to your comments about the new Telmex billing system. To call long distance from the US (or other foreign country) to a Mexico CELL phone you now need to dial 011+52 (country code)+ 1+area code+number. For example my number would be 011521612145-0050. If you are calling from the states to a Mexico land line, the "1" between the "52" country code and the area code is omitted. You would dial 01152612145-0050. Of course this is a big problem since people may not know whether your phone is a cell phone or land line.
