anyone know a cheap phone plan that is reliable? please share.

hello, please i am looking for a phone plan that's cheap at least less than $30 or $30. why? the reason i want a cheap phone plan is that i pay over $80 monthly on my current plan and i end up not using most of the features that came with the plan. for example, i don't use more than 2GB of the monthly data, and i hardly use up to 20 minutes in the call minutes. likewise, for text messages, of the people in my American contacts, only about 4 of them use android and i hardly exchange more than four texts with them monthly. how come? the reason i don't end up using more than 2GB is that i have wifi in my house, work, and night classes. and because most people use an iPhone, most of my text messages are through iMessage. likewise for the calls: they are mostly facetime audio. hence why i am looking for an alternative that's is very cheap and reliable with international text if possible or lack thereof. thank you.
