iphone secret codes

You would think the software engineers working at Apple must be so good they won’t have any need of amateur shortcuts to various kinds of tests during the whole product development. But even an Apple product can have an Achilles’ heel. That’s why, like android phones, they also have secret codes to help the product designers perform some quick tests on the iPhone under development. Here are some of these secret codes you can try on your own to test your iPhone’s performance any time.

Field Test Mode – 3001#12345#

When you dial this code, a screen pops open to give you iPhone’s technical information options. You must not proceed though if you are unaware of how the Field Test works because that is what it basically is – a field test. It gives you details about the signals on your phone.

Hide Caller ID – *31#mobilenumber

Once you enter the number along with the code on your dialer, your Caller ID will become hidden. However, the dial codes are different for every country. So, here is a list of these codes:

If you are unfamiliar with what an IMEI is, it is used to identify your phone’s hardware. To know this number, all you have to do is dial the given code *#06#.

Call Forwarding and Blocking

Every phone user has those days when they just want to avoid all the incoming calls either because they are in a meeting or just want to get some good sleep. Call forwarding lets you change the call’s destination and blocking, as the word implies, means blocking calls from a number. There are codes that allow you to do both.

Enable/disable Call Forwarding – *21#

Check Status of Call Forwarding – *#21#

Enable Call blocking – 33pin#

Check Status of Call Blocking – *#33#

Line Presentation – *#30#

This lets you in on the calling line presentation which is basically your identity that is shown on the person’s cell phone that you are calling. Through this code you can know whether your caller ID is working or not, and hence, fix the issue thereof.
