Houston - Phone
How to Use the Phone in the USA
The country code for the United States is 1.
   The area codes for Houston are 713 and 281.
   If you are in doubt about a certain area code, you can check the front of   the local telephone book, there should be a map of the U.S. and all area   codes listed.
   Typically, telephone numbers are written like this: (713) 569 8965, and   always have 10 digits. The first three digits are the area code and the rest   are the local number.
Public phones
   The most common   pay phone in operation today is the coin-operated type.
    To use one, pick up the receiver, deposit your money (the minimum amount is   posted on the machine), and then dial the number. An automated message will   alert you to deposit more money, if needed.
Credit card   calls
   U.S. telephone credit cards are not like the magnetic prepaid cards used in   some European countries.
   The telephone credit cards in the states are not prepaid, you have to   pay the telephone charges at the end of the month when the bill   arrives. 
   To use the card, you have to say or punch in you account number. 
   Contact your long-distance telephone carrier, AT&T, MCI or   Sprint, to get a telephone credit card.
Disposable phone cards
Telephone card phones are becoming increasingly common. Grocery stores, newsstands and other establishments sell the disposable phone cards in varying amounts, $5 and up. To activate the card, dial the code number and follow the instructions printed on the card.
Long distance calls
Competitive long-distance carriers make calling within the   United States relatively convenient and let you avoid hotel surcharges. By   dialing an 800 number, you can get connected to the long-distance company of   your choice. For details, contact

   Making phone calls
To make calls with the same area code, just dial the seven   digit local number.
   If you are calling another state or area code, dial 1 and then the ten digit   number.
   If you're calling from a distance but within the same area code, dial 1   and then the last seven digits.
   Like in many countries, there are special numbers for consumer information   and entertainment. In the states, the numbers that start with 800, 888   and 877 can be called for free anywhere in the U.S. 
   Usually these numbers are prepaid commercial lines, where   consumers can get information about products or services.
   A number that starts with 900 is not free and usually charges   you a very high fee. This is an entertainment number that offers   horoscope readings, sports updates or sexually suggestive conversations.
   
Directory and   operator information
   To reach the operator, dial 0.
    For a fee, you can dial 411 to get local or national phone numbers.   There is a free informatin line, 555 1212, but it has mainly commercial   listings.
   
   Charging a long distance call to another person
   If you want to charge a long-distance call to the person you're calling,   dial 0, instead of 1, before the ten digit number. An operator will come on   the line to assist you; however, the party you're calling can refuse to   accept the call.

    You can make   international calls directly from most phones by dialling 011, followed   by the country code and then the local number.
