Как узнать с какого номера SIM отправлять команду USSD *918*1*7XXXXXXXXXX#?

To determine from which SIM card to send the USSD command *918*1*7XXXXXXXXXX#, you need to know which mobile operator/connectivity provider the phone number belongs to. Each mobile operator may have different USSD codes and formats for specific services.

Here's a general way to find out which SIM card to use:

1. Check the phone settings: Open the settings menu on your device, and there should be an option related to SIM cards or mobile network settings. Here, you can find information about the SIM card's phone number associated with each slot. Match the phone number with the desired one you want to use.

2. Contact your mobile operator: Reach out to the customer support of the mobile operator of the SIM card you suspect to be the correct one. They can provide you with information about the phone number of that SIM card.

3. Use a different device: If you have access to another device, insert the SIM card you want to check, and then dial a known mobile number to identify which SIM card it is associated with.

Remember, it's essential to ensure that you have the correct USSD code and a valid reason for sending it, as USSD commands can trigger certain actions or services provided by your mobile operator.
