So at the moment, we have 3 lines including 1 smartphone & 2 basic phones on AT&T and currently paying I think around 70 dollars w/o texting, but were thinking of making it 3 smartphones. In ordee to do this, I need to find a plan that will give us the right amount of minutes a normal person would use, we don't NEED unlimited or thousands of minutes per month, we hope to have unlimited messaging though, and as for the data plan we want the lowest GB and/or cheapest because we don't often use the Internet out of our own wifi. And our budget is less than $150.
