Samrtphones and tablet devices have a variety of settings and apps as well, so the changes are that you can revert everything you want to, monitor anything you need to, but that is not always the case. Nevertheless, there are plenty of hidden settings like Apple’s iPhone has, with secret dialpad USSD codes help user enable to unlock their phone settings.
How that? There have been some settings that require a little tricky way in order to find, with phone software keeping some settings hidden from most users with technicians and tinkerers able to delve more deeply into the software and it works. Accessing these settings, or something, even simple status displays requires the entry of what have become known as secret USSD codes.
You have already know by now how to get into some of the deeper and darker settings hidden within some Android phones, but this time around talking about the iPhone. Are there some that are specific to Apple’s smartphone, and more importantly, how do you access them? Check this out.
All of these USSD codes need to be entered via the Phone app, and the input required of a handful of digits and characters followed by a tap on the call button. Simple and not difficult, but do be careful; sometimes, messing with these things can cause serious damage to your iPhone. You’ve been warned.
Now, with that out of the way, here are the codes you’re going to need!
*3001#12345#* – Activate Field Mode, which contains all of your iPhone’s more technical settings. It also converts the signal bars into an actual number.
*#5005*7672# – Check SMS center
*646# (Postpaid only) – Display your available minutes
*225# (Postpaid only) – Check your current bill’s balance
*#31# – Choose whether to hide your number
*3370# – Enable or disable EFR (Enhanced Full Rate), which improves your iPhone’s voice quality, but will quite likely reduce battery life
*#21# – Check call forwarding status
*777# (Prepaid only) – To check the account balance
*#62# – Check which number calls will be forwarded to if no service is available
*#76# – Check connecting line presentation
*#67# – Check the number to be used for call forwarding
*#33# – Check whether anything is barred, such as international calling etc.
*#61# – Check number of missed calls
*#06# – Displays your iPhone’s IMEI number

#43# – Deactivate call waiting
Don’t go changing settings unless you know what you are doing, though.
