As my post says: I have an old Motorola Razr, no data plan, no e-mail. It just makes/receives phone calls.
And as also posted I enter my address as mynumber@tmomail.net ("my number" is 10 numerals, without the 1 in front of the area code).
And also as posted, in fact, this is a bit less important to me than the reverse. I can't send a text message *out* of the Motorola to an e-mail address (with or without a picture).
