Affordable home internet for job applications (update)

I am worried about keeping my phone and internet on during my search. I worked as a production planner before this. Employers call and email constantly. What did you switch to?

I switched to a low-cost plan through my carrier and cut my bill by almost half.

Thanks for writing this out. I went through something close to it 5 months ago, and it got easier once I kept a simple log of every call and form.
