The prominence of SMS (Short Message Service) technology is evidence of a new era of communication. Imagine that you could send a question via SMS and, in just a few minutes, someone sends an SMS back with your answer. There are a number of companies that operate services like these. They pay people to research your question and reply with an answer. These services are free and they're growing more popular. If you feel comfortable doing a quick Internet search to answer someone's question, then you may be ready to earn money by sending SMS answers.
