For the value of $60, it should include at least 500min talk time, limited messages and a 1Gb limited non shared data. Additional 10 will get you unlimited or almost unlimited text. New activation, if any will be around $30, and also non refundable. Subsidiary phones will bind you into a 12-24mo contract. Early termination will cost you around $350 less $10 for each month of commitment. Renewing contract will save you around $70 from the remaining balance of the current contract or as the early upgrade fee rebate or as the new phone discount, whichever preferred.
Note that in US you pay both call and receive, apply to both voice and text. And the certain phone are specified to bind with specific plan(s).
