Is there any App that sends free international text messages on iphone?

Is there any appstore app guys, so that i can send free international text messages, or is there any free international text sending website?

Viber and tango

WhatsApp is the best for that!

If you speak spanish, you can use http://www.twinsms.com for send free sms

If you are talking real SMS (not messenger app over internet) - then there's no such thing as "free SMS" - it is a commercial service provided by network operators and you always pay for it one way or another - just sometimes not directly with money. By sending "free" SMS you provide the website with confirmed cell phone number of your friends or family - which is very valuable information for marketing etc. Apps can be worse - your whole address book is exposed and can be downloaded. Commercial sites usually have some privacy statement that at least promises your data will not be disclosed - but you will not find it on "free" websites. So in the end it is your choice of how to pay.

I personally use TimeClickr ( http://www.timeclickr.com ) for international messaging - they have good coverage, no contracts or plans, and turned out to be the cheapest for the countries I was searching. They give few free trial credits so you can check if it works for you before paying anything.
