ZeroSMS is a proof-of-concept demonstrating a way to send Class 0 SMS on android >=2.3.
/!\ This application only works on rooted phones.
Simply use adb to drop it onto your phone:
adb remount
adb push ZeroSms-signed.apk /system/app
And voila !
Type in a phone number (no phonebook pickup, this is a PoC) and a text, then press "Send SMS !". Your SMS is sent.
