Affordable home internet for job applications - any advice?

I use my phone as my only connection. I have read a lot of threads here and could not find my exact situation. I heard of low-cost plans for people with limited income. What did you switch to?

Keep everything in writing and save the confirmation numbers. It saved me later.

Thanks for writing this out. I went through something close to it 7 months ago, and it settled down once I kept a simple log of every call and form.
