Sprint chooses the best delivery method based on the capability of the recipient's phone. This is the most reliable way to send your message. Messages will be delivered as either a Sprint PCS Short Mail or an SMS Text Message (previously referred to as One-Way Messaging). Messages may be sent to customers of other wireless carriers using this method.
This option only delivers messages to Sprint PCS Phones. Your message is sent as an SMS Text Message. SMS Text Messages pop up on the recipient's phone; the recipient does not have to access the Web from their phone to get the message. Sprint PCS Short Mail users will not be able to reply to messages sent via this method. Some Sprint plans do not support the receipt of SMS Text Messages.
