FIRST TIP: DO NOT REPLY TO THE MESSAGE! Note the picture below, they say "Write NO to end" - yeah, right. I bet you anything that is a scam to get you to send them a message, which they can legitimately charge your cellular account any amount they deem. Plus, it confirms to them that your number is valid, and they can now sell your number to other spammers.
If you have AT&T, Verizon, or Sprint, you can "forward" the message to them. Here are the steps:
- Select the message they sent to you - on an iPhone, hold your finger down on the message, and tap the "Copy" balloon that pops up.
- Create a new message to 7726 and paste the message. (Double-tap in the text area, and tap the "Paste" balloon that pops up.)
- Hit send. You will get a reply message that asks you to send them the number from which the message was sent.
- Send the phone number.
(Since no other carriers have an iPhone, I didn't check - I mean, come on, just get an iPhone!! ;-) [Seriously, call 611 or your carrier's support line and ask.]
