Affordable home internet for job applications - first time posting

I am worried about keeping my phone and internet on during my search. 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 did you switch to?

Keep the number you use for job applications, even if you change plans. Employers will call it.

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