$80/month for 4 phone, 2 current year(getting bill credits) and 2 previous year (paid off) devices, 4 apple watch cellular lines and home internet is too much for service?You spend way too much for service, that's the difference.
I'm currently spending a flat $17.50/month for three cell lines, with no taxes/fees on top.
Actually my current bill is -$3 because I still have a bill credit from a 3 year old device.
