Aubey, I presume the higher rate for cellular terminations applies for Europe only...in Europe and in Latin America there is a concept called "calling party pays" which means that the person dialing pays both the LD but also a call termination fee. The numbering of cellular phones in these areas differs from the numbering of landline phones in the area.
The US/Canada practice of numbering both landline and wireless phones identically makes "CPP" tough to implement. In the test areas for CPP, if one dials the call, one gets a recording generally.
Contact the LD provider for guidance as to how country-by-country you can tell if a number is wireless.
