I've had this issue across multiple phones now, and I'm not sure why. If I send an email to email@example.com it never gets to my phone. If I login to vtext.com I can see the message as it should be, but it never shows up on my phone. I can send to firstname.lastname@example.org and it works. But since I keep my mobile data off most of the time, I don't want to use mms. What can I do to hopefully get this feature to work?
