Olympic gold medalist racks up massive data charges playing 'Pokemon Go' in Rio

Kohei Uchimura may need to sell his gold medal to pay all of those in-app purchase charges

Catch 'em all ... unless you're roaming.

Six-time world champion gymnast Kohei Uchimura found out the hard way that playing "Pokemon Go" can be an expensive habit.

The reigning men's all-around gold medalist is in Rio de Janeiro for the upcoming Olympics but apparently didn't restructure his data plan before he left. According to the AP, Uchimura racked up a bill of nearly $5,000, mostly by playing the uber-popular mobile game.

Luckily, his carrier service was understanding and reduced his bill to a $30-per-day unlimited data contract while he's abroad. Apparently Japanese providers are much more cooperative than their American counterparts.

Many Olympians have been complaining about the lack of Pokemon at the Olympic Village, so Uchimura must have been chasing the creatures all across the city to use such a large amount of data.

Regardless of his phone habits, Uchimura is expected to contend for gold once again at the Rio Olympics, which begin on Friday with the opening ceremony.
