How can I programmatically change the country & network of an Android phone's SIM without root access? I'm using this code to retrieve information:
TelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
System.out.println(tm.getSimCountryIso()); // prints 'us', but I want it to be 'fr'
System.out.println(tm.getNetworkCountryIso()); // prints 'us, but I want it to be 'fr'
As my SIM card is from the USA, both of the outputs are us. How can I programmatically make the output be fr (France) for example?
Basically, I want to trick my smartphone into thinking its SIM's country & network is France, for example.
Something like this would be perfect but it doesn't exist:
tm.setSimCountryIso('fr')
tm.setNetworkCountryIso('fr')
