View Full Version : AT commands for Samsung Champ

01-11-2011, 01:32 AM
Hi, i recently bought a Samsung Champ mobile phone. i would like to try AT commands over it, but am in kind of fix.

Probably some one with experience could help me with these:

1) How to use USB connected phones for AT commands?

2) At command List for Samsung Champ.



PS: I browsed the net, but could not find a solution to the first one. For the second issue, i read that most AT commands are the same for different mobiles.

Look into SIM 300 AT command reference.

For AT commands your phone should be detected as a Serial port , then simply use any terminal program to interact with it.
