Some straight talk phones use verizon towers & some use at&t towers. My son's phone uses at&t towers. I sent a pic from gmail to his phone like this ( for The ones that use at&t towers ) YOURNUMBER@mms.att.net To send as just a text message ( NO PIC ) use YOURNUMBER@txt.att.net I found this by sending a picture text from his phone to my email. And it showed up like this YOURNUMBER@mms.att.net . Then I just sent a text from his phone & it show up like this YOURNUMBER@txt.att.net . So just have them send a pic to your email then you got it.
