International text messages are still 20 cents. I thought it might be helpful to put together a list:
1. All these countries are two way (some are carrier specific)
Algeria
Australia (except Virgin)
Bangladesh (Sheba only)
Brunei
Cambodia (Samart and Shinawatra only)
Canada (Rogers AT&T, Telus and Bell only)
Central African Republic (Telecel and Atlantique only)
Cook Islands
Ecuador (Alegro PCS and Porta only)
Fiji
Guam
Hong Kong
India (Reliance only)
Iraq (Orascom only)
Japan (Tomen only)
South Korea (SKT)
Liberia (Libercell)
Malawi
Malaysia (Celcom)
Maldives (Wataniya)
Mexico
Oman (Nawras only)
Pakistan
Philippines (Globe and Digital only)
Saipan
Samoa
Saudi Arabia
Seychelles
Singapore
Syria
Thailand
Tonga
UK (O2 and T-Mobile only)
USA (AT&T, AllTel, Cingular, Nextel, Sprint and Verizon only)
Vietnam
2. There are another 100 (or so) countries that are 'One Way With Reply Path'. This means you can send a message but the recipient must reply within 2 days. After that the reply path is closed. In these countries the user can not send you a message out of the blue.
