There's always an option called:

- Crowdtesting;

You can basically hire remote testers from a specific country which will have specific mobile devices. It will be quite cheap if you want to do for example one test case, or short exploratory testing session.

**You could create a test case that requires them to walk like 2km or something like that. It really depends on what you are searching for :)**
