BP Totty,
To send a text message from your email account, you need to find out the domain based on your cell phone provider. For example, a phone with Verizon may be [email protected], Sprint phones may be [email protected], etc.
You can easily find the address to use on the company’s website.
The reverse is even easier – send a text message from a phone to an email account simply by typing in a valid email address instead of a phone number as the text destination.
