I have an emulator that I want to simulate the loss of a data connection while in my app. I have the receiver's setup correctly but I need a way to change the data connection via adb.

Is there an ADB command that turns off the data connection?

You can connect to an emulator via telnet

telnet localhost 5554

once connected you can set the network speed.

network speed 0

or

gsm data off

maybe you find this link helpful.

  • What about a real device? telnet doesn't work. And after `shell` command, `network` and `telnet` commands not exist! – Dr.jacky Jan 26 '23 at 10:29

From DDMS Perspective in Eclipse set denied/unregistered value for voice and data. It works in the Android Emulator 1.5.
