Best Cheap Phone Plans?

I have straight talk right now and i think it’s soon time for a new phone but my phone bill is the main thing KILLING my savings. It’s $50 a month right now which i know is a really good deal but with the job i have and where im at in life right now it’s not something im looking to splurge on. i do use my phone a lot but i was also looking to get a flip phone for calling and texting since i have an iphone now i can use my icloud for facetime and other things but i honestly dont know much about phones or plans😭😭 what are some good and cheap options for a flip phone?
