To change what TelephonyManager.getSimCountryIso() returns, simply execute

adb shell setprop gsm.sim.operator.iso-country no

and it now returns no (Norway).

If you want to change what TelephonyManager.getSimOperator() returns (MCC+MNC) then execute

adb shell setprop gsm.sim.operator.numeric 24201

and you have changed MCC to 242 (Norway) and MNC to 01 (Telenor).

To see which other properties you can change then execute

adb shell getprop

This is verified to work on both AVD and Genymotion. However, this does not change these properties persistently.
