Hackers can track your location through your phone. Press *#*#4636#*#* or *#*#197328640#*#* to see if anyone is watching your movements. These are Utility Net Monitor Codes. Dialing these codes can tell you if you're being tracked or monitored through your mobile phone.
You can find out if your phone has been tapped using unconditional data forwarding with the help of MMI codes. On GSM networks, dial *#21# to list, and ##21# to clear your unconditional data forwarding settings. CDMA network customers can view and modify these settings too by dialing **21*.
Call *#21# or *#62#
Did you know that there are two numbers you can call to find out if your phone is tapped? They may not work for every type of spyware, but you can learn a lot by dialing *#21# or *#62#.
##002# - If your voice call or data call, or SMS call has been forwarded, dialling this USSD code will erase them. *#21# - By dialling this USSD code, you would get to know if your calls have been diverted somewhere else or not.
*#21# tells you the status of your unconditional (all calls) call forwarding feature. Basically, if your cell phone rings when someone calls you — this code will return no information to you (or tell you that call forwarding is off). That's it. Is it good to switch off your Android phone whole night?
iPhone code: *3370#
If you ever find yourself somewhere getting poor cellphone reception, type in this code to turn on “enhanced full rate” mode. EFR mode improves your cell reception, but your battery life might be compromised.
*31# (Disable Caller ID)
If you want to keep your privacy and prevent others from knowing when you call them, you can disable caller ID by using this code. If you want to re-enable caller ID, just add the code again.
Call “##004#”
No one will answer when you call it, but it will turn off conditional forwarding on your phone. It will reset your phone to its default phone settings.
When you enter *#0*# into the phone's dialer, the device enters service mode and brings up a diagnostics menu. From this screen, you can view and run multiple diagnostics to test device hardware like buttons, sensors, and cameras.
Accessing Field Test Mode on an iPhone can be quite straightforward: simply go to your phone's dialer, type in *3001#12345#* and hit the dial button.
