Hello Friends Today I'm Posting Below The Sites To Send Free Sms Without Adds & They prove More Than 160 Characters To Send Your Message :

(1) Whozzat
You can send long SMS up to 470 characters using this survive. You can send free SMS without any ads. I do not know if this feature is for free users because they provide premium service too.
(2) SMSfame
SMSfame is another service that let you send ad free SMS unlimited, so you can use 160 characters with your SMS.
(3) Freesms8
Freesms8 is also in this list and let you send ads free SMS. You can send free group SMS. The site has some other features or services that you can use as ringtones, mp3 songs, games, classified etc.

(4) Total160
Yes you can use all 160 characters. And there will be no ads. You can send schedule SMS.
(5) Smsti
I have already discussed about this service in one of my previous posts, this site let you send free SMS of 160 characters without login or signup.
(6) Fullonsms
On this site there is nowhere mentioned that you can use full characters but its name is suggesting and I have found reference for this site so I have included this site in this post.
(7) Atrochatro
Atrochatro is already a popular name is SMS world but I just cant trust because site is known for sending SMS without login but you have to login so there is no surety you can send 160 characters , perhaps they will have limit. I have not tried this service yet. There is not mentioned about this.
