I'm currently on a family plan with unlimited data that my parents pay for. Im thinking about buying an EVO 4g off craigslist so i can just switch my current phone with the evo and stay on my current family plan. My questions are: If I do buy evo from craigslist, will my current plan with unlimited data be enough? Is there anything specific outside the condition and price of the phone I should look out for when buying one? Worse case scenario I'll have to get a new contract and pay for it myself. In that case does anyone know what the cheapest plan would be with evo 4g? I dont make too many calls. I make few to moderate amounts of text. Data wise I would be happy just using wifi. Any help would be appreciated. Sorry if these are dumb/repetitive questions.
