I am wondering how expensive this would be for a pre-paid plan as a last resort to google information or fetch some mobile sites. I know it is 10c to send SMS and 25c to receive MMS, so can we assume that it would cost a minimum of 35c per each request? If the browser requests more resources when the JS is executed, would it automatically result in more requests to be sent? Can this be somehow controlled? I have unlimited data, so don't need this, but the wife uses a prepaid plan and T-Mobile has no viable data options, so would like to give this option in case of "emergency".
