You can send an e-mail to a cell phone number within a matter of minutes. A cell phone that is capable of receiving an SMS can receive an e-mail. An SMS, or short messaging service, is a text message of 160 characters or less than can be sent from a mobile phone. Depending on the recipient's cell phone type, they may be able to receive attachments as well. You do not need special equipment or software to send an e-mail to a cell phone number. If you already use an e-mail account, you can send an e-mail to a cell phone number.
Determine the mobile service provider of the cell phone you want to e-mail.
Locate the mobile service provider's extension at the Outlook Express Versions and Updates website (www.oeupdates.com). The extension is the part following the @ in the mobile customer's e-mail address. It is similar to an e-mail account's domain name. For example, a Sprint customer's extension would be messaging.sprintpcs.com.
Access your e-mail account. If your e-mail is web-based, access the email's site. If you use an e-mail client such as Outlook or Thunderbird, open the program by clicking on the icon on the computer's desktop.
Log in to your e-mail account by entering the user name and password in the appropriate fields. Click "Sign In" or "Log In."
Click "Compose" or "New" to open a blank e-mail message.
Enter the email recipient's cell phone e-mail address. The email address will be the recipient's cell phone number + the mobile service provider's extension. For example, a Sprint's customer e-mail address would be email@example.com.
Enter a subject for the email in the appropriate field.
Compose the email message in the body of the email.
Click "Send" to send the email to the cell phone number.
If you do not know the mobile service provider of the phone you are e-mailing, use the search tool at Fone Finder (www.fonefinder.net). Enter the cell phone number, then click "Search by Number." The mobile carrier will be listed in the search results for the number.
