Correct, which is what you would expect. > The GSM API on Android, Windows Mobile, and > Blackberry allow you to differentiate between the home and current > operator... I've never been roaming on my app so I'd be curious to know what it did myself. > I have not tested getNetworkOperatorName() in a roaming situation, but > my assumption is that it returns the carrier that owns the current > cell site. getNetworkOperatorName() is all I use, although thinking about it I could see why you would use the getSimOperator -- the sim has the carrier info and that never changes.

You can also get that from getNetworkOperator() and parse the string.

But don't get me started on Android 2.0 and this CDMA stuff. Example: the CdmaCellLocation has two methods (getBaseStationLatitude() & getBaseStationLongitude()) which, judging from the name return the LAT/ LON of the site. Great, I'm thinking until I look at the datatype and see that they are both INTs. Which, again, wouldn't be a problem if they said, "To get the decimal value divide by 1,000,000", but they don't. Another beautiful mystery is that onSignalStrengthChanged has been depracated, but they don't state what the replacement is.
