Basic, cheap prepaid plan for flip phone??

I had an android that the charging port in it stopped working and would no longer charge... I haven't been able to afford to buy another and with me currently seeking employment, I need a phone for potential employers to contact me. I have a flip phone that was on an AT&T contract until it was removed from the multi-line plane a couple of months ago. What is a cheap talk and text option I can go with temporarily for a month or so until I can afford to go back with a smartphone with data? At the moment, I just need a way to be contacted about my 3 yr old son and by employers and don't need data, as I use my tablet on Wi-Fi
