What does *# 21# do? There are a lot of USSD codes or secret codes as most people would refer to it that are used to easily access certain information about your phone. These codes may only be known by the privileged. In this article, we’ll talk about one of such codes and what it does.
What does *# 21# do?
There has been information circulating on the internet that dialing the code, *#21# gives you information on whether or not your cell phone has been tapped or not. This may not be entirely true.
The code *#21# is used to find out whether your cell phone calls are being forwarded unconditionally to a separate device. Basically, if your phone is able to ring when someone calls you then this code is not relevant to you.
This code comes in handy when you suspect that your phone call has been going to another user instead of you. This code can be used on both Android and IOS devices without any setbacks. All you’ll need to do is to open your phone app on either your iPhone or your Android phone and dial *#21# and hit call. This will return the information about your unconditional call forwarding settings.
