In this post we will discuss about secret interrogation codes about your Apple iPhone 7. The codes can unlock a lot of cool features in your mobile, So read on and we’ll inform you about a series of hidden codes that unveil secret actions. These codes will work on Apple iPhone 7 and iPhone 7 Plus. These short codes will either uncover hidden menus or act as direct commands. They provide additional information about your device and tweak current settings.
Some codes might not work on the model which you may be using but don’t worry we have plenty of these codes for you to try on your phone.
These secret codes are combinations of numbers and the *(asterisk) and # (number sign) symbols. They are used with the help of your iPhone’s dial pad. Simply open the Phone app and tap on keypad. Now, input one of the below codes. Depending on the type of the combination, you’ll have to press the green call button or not.
The first step is to open the iPhone’s dialler application
Now you can enter any of the Hidden Codes shown below and may or may not press the dial key based on the operation of the code.
1. Â *3001#12345#*Â and tap Call.
By accessing the hidden iPhone Field Test mode you’re able to find out live updated information about your cell phone network. You can uncover the numerical value of your cell phone signal and read data about surrounding cell towers. If you tap on the numerical valued carrier signal, available in the top left corner of your screen, you can switch between graphic and numerical display.
2. Â *#06#
Shows your IMEI. No need to tap Call. IMEI is the unique identifier for your mobile phone hardware.
3. Â *#21#Â and tap Call.
4.  *#43# and tap Call.
Status:Â *#43#Â | Enable:Â *43#Â | Disable:Â #43#
This number will give you the status of the Call Waiting on your phone. You can activate or deactivate Call waiting on your phone from Settings apps as well but this neat trick also gives you the update on call waiting for your data packets as well as text messages.
5. Â *#33# and tap Call.
Status:Â *#33#Â | Turn ON:Â *33*pin#Â | Turn OFF:Â #33*pin#
These secret codes help you to check the restriction status of all your outgoing calls, data usage, texts and so on. Call barring is used to protect yourself from accidental calls when you allow your child to play with your iPhone, for example. iOS currently doesn’t offer a menu Setting for blocking outgoing calls. However, this can be turned back off easily by anyone. Instead use the above codes to block or unblock all outgoing calls. Replace ‘pin’ with your SIM card pin, NOT iPhone Passcode!
6. Â *#31#
Status: *#31# + | Current Call: #31#phone-number + ‘Call’
When initiating and outgoing call you have the option to make your phone number available for the receiving caller or to hide it. Anonymity status can be checked with the first of the first code provided above. To initiate an anonymous call you can either edit your contact or directly use your iPhone keypad to add the #31# code in front of the dialed phone number.
7. Â *3370# and tap Call.
EFR Mode –Â Enhanced Full Rate is a speech codding standard that improves voice quality for GSM conversations. It also burns a little more battery life. (not available on all networks.)
8. Â *#30#Â and tap Call.
Check the calling line presentation. This shows whether you have enabled or disabled the presentation of the calling line, presumably the number of the party placing the call.
9. Â *#5005*7672# and tap Call
Dial this code to get your carrier’s text message center number.
10. Check Balance
Prepaid:Â *777#Â | Postpaid:Â *225#
Use these codes to check balance of your iPhone.
It’s worth noting that you should only use these codes and play around with your settings at your own risk, if you’re not sure what something does better leave it. And as always Happy Interrogating.
