Keeping my phone on while I search after 8 years as an accountant

I am worried about keeping my phone and internet on during my search. There are 8 people counting on me, so I am trying to be careful. 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.
