How to simulate Airplane mode?

I'll be overseas and don't want to be racking up roaming or whatever other charges. Typically I would use the Airplane mode, but I still want to be able to take photos that have the geo locations recorded.

So I want to know whether turning off Settings/Cellular/Cellular Data will take care of what I want (e.g. remove the chance that I'll be inadvertently charged for something)? It says Cellular Data...does it mean I have to turn off Cellular Voice somewhere or does this do the trick?
