is there an api that can check for network roaming support
whenever you connect to another carrier across
other countries ?

Looks like RadioInfo.getNetworkService() will help you. See javadoc for it.

thanks for the tip Skipper_Joe. I've started reading the api but
i'm still not sure what the networkservices mean so i have a followup
question

1) Is my logic below valid for checking roaming support? I
check for roaming support by evaluating for two requirements

//in pseudocode
currentServices = RadioInfo.getNetworkService()

if ( (currentServices Doesn't Inlcude NETWORK_SERVICE_IN_HOME_ZONE)  && 
     (currentServices Includes NETWORK_SERVICE_ROAMING) )
{
   // therefore roaming supported
}

Frankly speaking, I didn't use this method myself. I just used RadioInfo class and remember that something about roaming was there.

it's not clear too me from javadoc, what NETWORK_SERVICE_IN_HOME_ZONE means (what's is 'home' zone?). So I'd check for NETWORK_SERVICE_ROAMING only.

The home zone refers to a service offered by some carriers where they give you special prices when your device is connected to a specific gsm cell tower, usually the one it connects to when you are at home. You don't need that to get the roaming information, RadioInfo.NETWORK_SERVICE_SUPPRESS_ROAMING is enough.
