Sonoc C1

Sonoc C1 is one of the cheapest phones you will see here. It supports dual SIM and it's with big speaker.
It's one of my favorite mini phones. Supports camera and bluetooth.
You can have it for only $16 with free shipping on Chinabuye.
It have many functions as MP3/MP4/WAP/Bluetooth/SMS group sending/GPRS download/MMS/Calendar/Calculator/Tasks/Alarm clock/ Memory extended.
It's a great deal if you have low budget. Small phone with awesome design that you can carry anywhere
without the need to recharge it often because it's battery life is very long.
Great SONOC series phone to have.
