(ORDO NEWS) — Users can query the operator’s service application using MMI codes, often referred to as “secret” codes. To do this, it is necessary to form a USSD request, consisting of a set of numbers, an asterisk at the beginning and a pound sign at the end, the director of the Intellectual Reserve company Pavel Myasoedov told the Prime agency.
According to him, such codes allow you to find out the necessary information for subscribers: to clarify the balance of the account, the amount of debt, disconnect or connect services, change the tariff plan. Most of them are universal, but there are also special codes for users of devices on Android and iOS.
So, owners of smartphones on Android can find out information about the IMEI using the combination * # 06 #, the combination * ## 7594 ## will help to turn off the phone urgently, reset the phone to factory settings – ## 7780 ##, delete all SMS messages – # 5376 #.
Myasoedov advised iPhone users to remember the command * 3001 # 12345 #, which brings up a hidden menu with information about the SIM card, cellular operator’s network and signal strength, and * # 5005 * 7672 #, with which you can find out the service center number for your cellular operator …
These combinations can be useful for people in the absence of the Internet and a limited time. However, MMI codes have drawbacks – for example, frequent errors, device reboots, problems obtaining information when the SIM card is physically worn out. In addition, this system is losing popularity every year due to the fact that device owners need to memorize complex combinations.
