There isnt always one. Talk to your friends and make sure you have their phone numbers. Nextel customer care can submit a ticket so another department can do a bit of research on who is smsing you, and that other department can stop unwanted spam, even if from a source unknown to you. However, if you have an idea of who is smsing you, just tell them to sign the messages, get their phone numbers, and use the phone numbers to reply via email.
