So... after spending some time reading the documentation I could
figured that out! I realized that I was trying to work with the wrong
classes... here is a sample code that I placed in my onCreate method
to check the roaming status:
Java:
TelephonyManager tm =
(TelephonyManager)this.getSystemService(Context.TELEPHONY_SERVICE);
if(!tm.isNetworkRoaming()){
// roaming is off
} else if
(tm.getSimCountryIso().equals(tm.getNetworkCountryIso())) {
// national roaming
} else {
// international roaming
}
I'm not completely sure about this national and international roaming
stuff, but I've tried with many kind of SIM cards and they all seemed
to work perfectly!
Hope it'll help those that got into the same difficulty I did.
Cheers!
