Recommendations?

Hi Everyone, I'm completely addicted to my phone and need to get rid of it. I've tried minimalistic apps, and I just find a way around it every time. I need something with calling and texting but I don't want any apps aside from GPS or Google Maps. I don't mind having two devices for this, but I'd rather not spend a ton of money (under $300 altogether). Are there any devices or ideas that stand out? I thought about Punkt because I think you could use hotspot for a gps device, but I'm not sure.
