Data roaming in android

Question

hi,

Here's a question that comes from an unclear view of how things work : can a a phone be data roaming without being voice roaming ? If so how can a begin data roaming event can be detected ? This question came to me from the DDMS options , where one can have" data roaming " and "home voice" .

Answer 1

The simple answer: No!

It is not possible since the roaming services comes with the visited network asking home network if (1) there is a roaming agreement and (2) if the SIM-owner is allowed to roam. Thus voice roaming and data roaming is always done together.
