At the moment, there’s been list of secret Apple iPhone codes that can unlock hidden features and settings circulating on the web.
These codes allow users to be able to do anything from enhancing their call quality to checking their mobile balance and more.
While Android phones have been particularly known for allowing a rabbit-hole their operating system to be tweaked and modified, Apple’s iOS has kept its menus and settings on lock down.
However, because of the release of this list, there is now a way for users to drill down find some hidden features generally not known to the public.
If you want to find out how many minutes you have left on your phone tariff, what your IMEI number (something you’ll need if you swap phone networks) or even find out a way to enhance your iPhone’s voice quality there’s a way to do it that you won’t find by going to your normal phone’s settings.
Redmond Pie revealed a full list of the codes and how to properly use them.
By typing in the following USSD codes on the dialpad and then pressing the call button, you can access the following features:
*3001#12345#*:Field Test mode
*#5005*7672#: SMS centre number*3370#: Turn on or off EFR (Enhanced Full Rate), a mode that improves your iPhone’s call quality
*#06#: Find out your iPhone’s IMEI number
*#31#: Hide your number on calls option
*#43#: Check if call waiting is on or off
*43#: Turn on call waiting
#43#: Turn off call waiting
*646#: Check minutes left on contract
*225#: Find out your current mobile account balance
*777#: Find out prepaid account balance
*#61#: Number of missed calls
*#21#: Call forwarding status
*#67#: Call forwarding number
*#33#: Find out what mobile services are disabled on your phone
One of the most interesting codes as feature don this list is the Field Test mode, which allows users to see their phone-signal strength measured in numbers rather than those five bars.
You’ll see something displaying such as ‘-90’, with the number going up and down depending on signal.
A value above -80 is a full-bar strength, but anything below -110 is very weak.
This is a more accurate way of seeing whether you have enough signal to make a call, rather than holding on to hope with one-bar.
NOTE: 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 be.
