The USSD and MMI codes usually hold an asterisk or a pound symbol/hashtag at their beginning. You can find the updates of codes daily because the latest android software versions are released. A few manufacturers contain their extra special codes.
You can easily enter the code. Hence, you have to bring up your dialer keypad merely. Just type the number correctly with the correct sequence. You should know that there are a few carrier-specific codes. It is the reason why you can’t apply them on all mobiles. Therefore, when you find your mobile not responding to a code, you don’t need to try twice. You can try another one then.
Unstructured Supplementary Service Data is the complete form of USSD. You can use the codes between your mobile and mobile network operator. It indicates that you must always be connected to your carrier so that the USSD codes work.

Enthusiasts use the USSD codes. However, carriers usually have their own app/website, due to which you can access the details quickly. The codes are carrier-specific. You can’t use the codes for all carriers. Contact the carrier that is relevant to you.
The codes belong to the Man-Machine Interface schema. You can use the codes for any particular brand or model. With the help of these codes, you can learn exciting things.
