Shop around a bit and you’ll see that the major wireless carriers expect you to pay for infinite voice calls and text messages at a minimum, with monthly charges escalating based on how much cellular data you want on top of that. A typical Verizon family plan gives you 8 gigabytes of cellular data shared by four lines, plus unlimited talk and text, for $145 a month. A single line with just 2 gigabytes of data, plus unlimited talk and text, is $75 a month. Strip it down to a single gigabyte of data, plus unlimited talk and text, and the charge is still a healthy $60 a month. Sign up for a contract and you’ll get a subsidy on a new phone, but you’ll quickly make up the difference on your monthly bill.
