I used to be able to send text from my email to my phone by entering the firstname.lastname@example.org.
But not anymore. According to Verizon's vtext.com page, you should be able to do this:
Text to mobile phone from E-mail, send and receive text messages from any email address in the world by addressing the email to your 10 digit mobile number, email@example.com, or your firstname.lastname@example.org.
You haven't added a block to your line regarding texting from the web, have you? That's the only thing I can think of. I just tried it since it had been awhile since I'd sent one, and I had no trouble sending a text to myself from my e-mail.
If you don't know how to check about the block, then I doubt that you've set it up. Here's how, if you need it:
log into your on-line MyVerizon account
click on the blue More Actions (under I Want To)
click on the blue Block Internet Spam (under Safety & Security)
at the top of the page, choose line/phone, if applicable
at the bottom of the page, ensure that both check boxes are unchecked under Message Blocking Preferences
I may be misunderstanding you ... you send a picture message to vzwpix.com and it goes through? Wahoo, it's working as it should!
If you send a picture message to vtext.com, it doesn't go through? Well, it's not supposed to ... you can't send picture messages to vtext.com
Or are you saying that you still cannot send a text message (with no attachments) to vtext.com?
