If you send a long text message, the iPhone splits it to multiple SMS’s, which will be individually billed by your operator. TXT Saver counts the number of characters (typed and remaining) and the number of SMS’s while you edit a text message. Unlike other apps, TXT Saver understands the difference between 160 and 70 character long SMS’s. The Compress function helps you to convert your Unicode characters to standard GSM 7 bit characters and helps you to save your SMS bill!
