If you are calling from a mobile phone, you can substitute the “00” for the “+”, usually located on the 0-digit key. You can usually select it by clicking and holding until the “0” switches to a “+”. You will then continue to dial the country code and telephone number as usual. For example, +1 (555) 555-5555.

Visit the All-Area Codes website at http://www. allareacodes. com/ for help with identifying the correct area code for the telephone number you’re dialing. If the phone number is a mobile number, the area code may no longer represent the geographic region the owner is actually located in. Contact the person via mail or email if you do not have this portion of the phone number.
