It has long been sitting in my head the idea that it is time to get rid of it with his GSM billing depending on the destination of the call or text message. You just want a smartphone and unlimited internet. Mobile Skype has already decided the issue of free calls anywhere in the world, and the application JaxtrSMS It allows to send free sms to any mobile number anywhere in the world no matter whether the recipient uses this program or not.
An application requires only the presence of the Internet on your mobile device. JaxtrSMS just clings to the address book and all. There is no limit to the number of messages. The most important thing - the recipient will see your real mobile number, while sending messages through site operator or other services do not display the sender's number, forcing it to enter into the text posts.
Now cons: does not support Cyrillic, but JaxtrSMS is still in beta status, so it is necessary to expect the addition of support for Cyrillic fonts in later versions. besides
AndroidThere are versions of the application for iOS, Blackberry, SymbianAnd soon perhaps for WPM.
