Using Audacity 1.3.4, there’s an effect called Leveller. I used settings of “Heavier” and “-60dB” and it improved it a tiny bit. It’s louder, that’s for sure.

But seeing as how it was recorded with a cell phone, it’s not going to ever be much better than that. You can’t magically add quality to a file once it’s already been recorded.
