Added the ability to view the number of the SIM card hub in the application without entering the USSD code.
The functionality of this function directly depends on whether the information on the number was added by the SIM card manufacturer to the SIM card. If your application does not display the number of the hub's SIM card, there are two options:
- use USSD code, which you can find the number of the SIM card*;
- replace the SIM card of the hub with another SIM card.
* a similar USSD code may vary from country to country.
