UPDATE (March 2013): A few months ago, all cell phone numbers received an extra digit. Just add a “9” after the first zero and it will work.
The phone system is very simple in Ecuador. Just follow these simple directions, and you’ll have no problems when calling from within the country.
1) Ignore the country code of 593
2) Dial the one-digit area code. Each region has a different code. A “0” must be dialed before the one digit area code:
3) Then dial the seven digit number (XXXX-XXX). Thats it – you are connected.
For example: to call a land-line in Cuenca, you would dial 07-XXXX-XXX. Many businesses (and their ads) take the area code for granted and don’t include it in print – you will need this code even to dial numbers in your own city.
Cell phones have a 08 or 09 area code, for the country, followed by a seven digit number.
