Searching for a free international texting app

ever heard of whatsapp,viber,line,bbm? other than that there are no free sms apps,you have to pay if you want to send texts abroad,your only solution would be messengers mentioned above or a network plan that includes international messages

Nik is right, international SMS is generally handled by your wireless carrier at an extra fee and is not generally possible without paying somebody. With Skype (and I think certain Google apps) you can SMS any number worldwide, but Skype charges a pretty hefty fee for it and I've rarely found it to be worthwhile. Your wireless provider may have an international SMS plan that will give you international texting options, but it will be limited to a certain number of texts and may not be cheap.

Why can't you use a Wi-Fi messaging application like Kakao Talk or Whats app?
