Keeping my phone on while I search after 15 years as a medical assistant

I am worried about keeping my phone and internet on during my search. Employers call and email constantly. What else should I consider?

Thanks for writing this out. I went through something close to it 6 months ago, and it settled down once I kept a simple log of every call and form.

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