Telephone

The country code for Bangladesh is 880. Add a 0 to make a call to any Bangladesh city or region outside the national capital. It is not possible to access international information (directory assistance) from within Bangladesh. If you need international directory assistance, check the Internet telephone directories. Landlines are a rarity in Bangladesh, and aren't reliable even when you can find them. Bangladesh Telephone Company Ltd. (BTCL or formerly BTTB, known generally as T&T) is the public sector phone company and the only landline service in the country. Mobile phones are a better bet and widely available. In most towns they'll be your only option, and many shop owners let theirs double as PCO's / ISD's. Banglalink  and Grameenphone  are the most widely available, followed by Citycell , Aktel , Teletalk  and Warid . Except Citycell all work on the GSM network and offer prepaid packages at reasonable prices – usually about Tk 140 ($2) to get started. International calls are possible, and often more reasonably priced than you would expect if you're calling the US or major European countries although prices can rise drastically as you get more off the beaten path. E-ISD facility offered by different mobile phone service providers can reduce the cost significantly. For the E-ISD service dial 012 instead of 00/+.

Internet

Internet is available in most of the larger towns, with prices hovering around Tk 15-20/hour. Most are on broadband connections, but speed does not meet international standards. WiMAX service is now available from some internet service providers. You can also find WiFi connectivity in some places around the big cities.
Internet calls may be be possible, though the Information Ministry has outlawed them. Try Dialpad , Hotelphone , Mediaring or Skype . You'll likely need your own microphone/headphone.
