Should sending picutre messages to an email address incur data charges? My son sent a bunch of pictures from his phone to his yahoo email address and the bill shows no data charges assigned to his phone. I sent a bunch of pictures from my phone, first to a pop3 email address and then to a yahoo address and all of them incurred data charges. We have an unlimited text messaging plan that includes picture and video messaging. It seems to be working as expected for text messages to other phones, but I don't understand how it works for sending to email addresses. Can anyone explain it for me? Thanks.
