The experts carried a study that found that sending important information via SMS was not a good idea. The fact is that before the message reaches the final destination, it will go through several switches.
Initially, the message is sent to the nearest cell tower, then to a special SMS center, then to the tower closest to the recipient. Due to this multi-stage, cybercriminals can catch the message without difficulty.
Therefore, do not send important information via SMS messages, as there is a great risk of its interception. It is better to use messengers, one of the most protected is Telegram.
