Affordable home internet for job applications - first time posting

I use my phone as my only connection. I have read a lot of threads here and could not find my exact situation. Employers call and email constantly. What else should I consider?

Libraries lend Wi-Fi hotspots in some towns. Mine lent one for three weeks.

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