Keeping my phone on while I search after 15 years as a social media manager

My home internet costs more than I can manage on unemployment. 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.

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