You can dial most international calls directly. Before calling, you will need to know the country code and the city routing code in addition to the local telephone number. You can look up country and city codes at CountryCallingCodes.com

To dial an international call:

1. Dial the international access code “011” (for operator-assisted calls, dial “01”)
2. Dial the country code
3. Dial the city routing code
4. Dial the local telephone number; if you have touchtone dialing, press the # key after dialing

It may take extra time before you hear the phone ring on an international call; allow at least 45 seconds.
