I know that calls 0845 & 0870 are free with this package, but what about calls to all other non-geographic codes?
e.g. I know some 03xx numbers are local rate normally, but are these also free with this package?
See http://www.productsandservices.bt.com/products/lib/pdf/BT_PhoneTariff_Residential.pdf page 5.
03 numbers are treated like normal land-lines. Most 0845 and 0870 numbers are included in your calls package (but see the small print in that document). Other non-geographic numbers are chargeable.
