Affordable home internet for job applications after 13 years as a social media manager

I use my phone as my only connection. There are 13 people counting on me, so I am trying to be careful. I heard of low-cost plans for people with limited income. What else should I consider?

Thanks for writing this out. I went through something close to it 3 months ago, and it got easier once I kept a simple log of every call and form.
