Spoofed SMS's are pretty useful in some cases, not just to play pranks on your friends but also to SMS others when you don't have enough balance on your phone.

Spoofed SMS? What does it mean?  

You can send an SMS from any phone number you like. That's what it means. No, really, you can send your friend an SMS and make it seem as if he sent the SMS to himself (i.e. you can make his number appear on the FROM field of the text message.) Pretty cool, huh?

Here I am going to list some of the sites that allow you to send Spoofed or Fake SMS without having to pay any money.

SMSGlobal

Sign up on the site and you will get 25 credits for free. Depending upon where you want to send your fake, spoofed SMS, you can send about 20 free SMS with those free credits. And once your free credit is all consumed up, you can re-register with a new phone number and get another 25 credits again.

After you sign up, you should receive an SMS on your phone with the password to login to SMSGlobal.

Login to SMSGlobal.

Click on Send SMS to Number on the right side bar.

On the new page, enter the receiver's number, the Sender ID you'd like to show for the SMS, both in international format (i.e. +Country code and then the phone number) and then fill up the Message field with your message and click on Send. If you select Sender ID under Reply To, your fake sender number will be displayed as the sender of the SMS, however if you select Email, the SMS will be sent from a different number (and if the receiver replies to that number, you'll receive it on your email.)

Lleida

I had to personally go through a huge list of SMS sites before I came across this awesome site. It is much better than SMSGlobal in the sense that it allows you to put a text on the SENDER ID. That means, you can send SMS from a text rather than a number. You can now send SMS to your friends and display your name as the sender!

You get 20 credits just for registering on the site, and with it, you can send about 20 free SMS's. As before, register again with a new phone number if you'd like to send more fake SMS's.

Register on the site. You'll receive a code on your mobile number.

Enter that code on Free account code text field and click on Send.

Now, check your email. You should have received an email from Lleida with your Client account username and password.

Go here and login with the client account username and password that you have received on your email.

Enter the message you'd like to send, the receiver's phone number in international format and fake sender ID (Both texts and number supported). Then click on Send.

SMSian

You can send one SMS after registering for free.

Register on the site, you'll receive a code on your mobile, enter the code on the site and validate your account.

Login to the site and you'll be able to send the SMS.

The site claims that you can complete FREE surveys and get more credits, but I haven't been able to get any surveys at all.

TxtSpoof

You get one SMS credit for free.

Register and Log in to the site. Then like them on Facebook.

Now go to the free credit application on their facebook page. You should see Click here to get one free credit written there.

Click on that link, and you'll be able to send one spoofed SMS for free (supports  numbers only).
