HowStuffWorks explains that sending a text message from a computer requires opening an email program or Web email and creating a new email message. In the “To” box, the sender must enter the recipient’s mobile phone number followed by @teleflip.com.
When sending a text message from a computer, the user can enter the suffix provided by the recipient’s service provider. Every provider has a distinct email suffix that guarantees the message is properly routed. According to HowStuffWorks, some provider suffixes include: @messaging.sprintpcs.com for Sprint, @tmomail.net for T-Mobile and @vtext.com for Verizon. When sending a text message to an unknown service provider, substitute the service provider suffix for @teleflip.com.
