I am just getting started looking into prepaid cell phones. I really want to get one of these, but I am not sure which company to go with, or which type of plan to get. Is it better to use Tracfone Airtime Cards or to buy a monthly plan and buy any extra airtime I might need online? Has anyone tried this company before? I want to find some customer reviews so I can see if there are any issues I should know about before I make a final decision. They seem to be pretty reasonably priced from what I have seen so far.
