Hello for a project i need to test the behavior an application for mobile phone in situation there is no cellular data available. in some cases i have successfully been able to test this in the lift at my work place, however at home i cant do the test as there is no lift :). i tried to recreate this situation by wrapping a box with aluminum foils without success.

Any suggestion how i can create a box in which there will be no cellular network inside ?


You want a Faraday Cage. Connect your aluminum foil box to an electrical ground, and that will prevent cellular signals from passing in/out of the box.

  • It doesn't have to grounded. It does have to be continuous; any hole larger than the mesh in your microwave door will let a signal in. – Ricky Aug 19 '15 at 2:23

Finally i decided to look for an old phone and will just remove the antenna


Have you tried enabling Airplane mode? Most modern phones support airplane mode which disabled cellular data and wi-if.

  • good idea, however in airplane mode the phone does not send events to sim. – Rajneesh Kumar Gobin Jul 28 '15 at 10:30
