It baffles me how few people realize you can send a text message from your cell phone directly to your email address. Instead of typing in a phone number, just enter the email address. I use this nifty little feature all the time to send myself reminders or to get photos off of my phone. In the address book on my phone I have contacts specifically created for Flickr, Gmail, my SVSU email, and maybe a few others.
Verizon even lets you send something from an email address directly to your phone using vzwpix.com. The service creates an email address of xxxxxxxxxx@vzwpix.com where you can send the email to. Their service then converts it and sends it on to your phone as a text message. I don’t know if other cell phone service providers have something similar, but I’d imagine they would. If you know of something, leave a comment.
