I was looking for a program to send free SMS but all I was finding was to send free text messages within the app such as WhatsApp. They require both sender and receiver to have the app and be online which is not what I wanted. Then after some digging I found JaxtrSMS which allows you to send free SMS to anyone even if he doesn’t have the app. The other benefit is that as sender you declare your phone number and receiver knows that you are the sender. Other apps show a strange number even from another country. JaxtrSMS is available for almost any mobile OS including iOS, Android and Symbian. You can find more and download it from the source link, it is completely free.
