Why do I send one message, and the amount debited from the account as for two?

One long message can be broken into several SMS, for each of which a separate fee is charged. One SMS can contain 70 characters with non-Latin letters (for example, in Russian) or 160 characters with only Latin letters. To send a longer message, it is divided into several SMS, and a special header (UDH) is added to each SMS, allowing the phone to combine the received parts into one long message, and the maximum length of each SMS in this case becomes 67 characters for non-Latin and 153 for Latin letters Part of the characters, for example, "№`" do not belong to Latin, therefore, messages containing similar characters are encoded as messages with non-Latin characters. There are also some special characters for which 2 characters are always used to encode - this is "{} [] ^ ~ \ | €".
