<prompt> Human: I want to get a 100 dollar a month phone plan, Im 16 and Im earning 120 a month Is it a good idea or a bad one. Should I just save up instead?  <response>: Yes, spending 83 of your income on your phone plan is a bad idea. Save money to pay cash for a phone, and browse rnocontract for a prepaid plan that will be affordable for you. If you limit your data usage you should be able to get a budget plan for 30-40 per month, which is much more reasonable for your income.
