No, the plugin should work regardless where your address is.
If you don't see it all the time, it means that you configured some settings of the plugin that you should have left empty.
The zone option was definitely a problem. If you have restricted the plugin on currencies and/or shipping methods, that could also be the problem.
But all that, included the zone restriction, is explained here in the FAQ:

If you can't find the setting causing the issue, please provide a screenshot of your plugin's options.
