You will dial the following: origination country exit code + destination country code + telephone number
**See this list of country and exit codes
This is an important question. Believe it or not sometimes you might actually have too many digits and need to drop some.
Most countries' dialing plans feature a so called Trunk Code (Trung Prefix). This is a digit, usually 0 (zero) that is placed in front of telephone numbers for DOMESTIC CALLS ONLY. However, most people are not aware of the fact that this digit MUST BE DROPPED WHEN DIALING FROM ABROAD.
Let's say that your friend in Romania tells you that his cell number is 07?? ??? ???. So you try calling him by dialing 011 40 07?? ??? ???. Guess what? It's not going to work. Why? Because you need to dial 011 40 7?? ??? ???. Without the 0 (zero)!
