I am projecting an IO device controlled via sms. It could be interesting for me, to know how many digits are used to make a national phone call in the various country.
For instance, in my country we need 10 digits for a national call (3 digits for the operator + 7 for the cellphone).
Since it is my intention to publish the final project, if I will obtain some answers from the forum members, I could end up (if feasible) with a system that could be used globally.
Please, along with the digit length, indicate also the country.
Al.
