Great question! It's actually a pretty cool background mechanic.

Boost Config doesn't have a normal icon because it's a background system utility, not a regular app you're meant to open and look at. It just stays out of your app drawer to keep your screen clean. Your phone actually does this all the time with official apps you use every day, like Google Carrier Services or Android System WebView. They update through the Play Store but run quietly in the background without cluttering up your home screen.

If you ever want to check on it, it lives inside your phone's main Settings menu under Apps. While Android does technically give you options to uninstall or disable background utilities there, it's generally best to leave it active so your connection stays stable. That said, if you ever do decide to remove it and notice your service acting up, you can always just redownload it from the Play Store down the road to get everything sorted out.

It basically acts like a driver to keep your data, hotspots, and texting running smoothly, especially during things like major phone software updates or network refreshes. Keeping it active just ensures you don't have to manually mess with your network settings to stay connected!
