Discover the 10 most useful USSD codes for Samsung, Xiaomi, and iPhone users. <\/h2>\n\n\n\n

The end of the year is approaching, bringing a moment of peace. And let\u2019s be honest\u2014it\u2019s a time we\u2019ll spend not only with loved ones but also\u2026 with our phones.
Beyond the advertised features and downloaded apps, your phone has its own secrets, which can be unlocked using specific USSD codes.
Let\u2019s dive in.<\/p>\n\n\n\n

What is USSD?<\/h3>\n\n\n\n

Do you recognize sequences of numbers preceded by # or *? These are USSD codes, or Unstructured Supplementary Service Data. To activate a code, simply type it in the same place where you usually enter a phone number, and then start a \u201ccall.\u201d
But that\u2019s where the similarities end. One of the biggest advantages of USSD codes is instant communication with your phone or mobile network operator, bypassing apps or websites. Think of it as a side gate you can use to \u201cskip the line.\u201d<\/p>\n\n\n\n

There are many USSD codes. Some unlock entirely new possibilities, while others may cause malfunctions or even erase all data from your phone. We\u2019ll cover those risky codes in a separate article.<\/strong><\/p>\n\n\n\n

It\u2019s also worth noting that some USSD codes are universal, while others work only on Android or iOS devices. Additionally, mobile operators and phone manufacturers often have their own USSD codes, which work exclusively on their devices. We\u2019ve compiled nearly 100 codes and categorized them, which we\u2019ll gradually publish on our portal.
Here, we present the 10 most useful ones.<\/p>\n\n\n\n

10 Most Useful USSD Codes for Your Phone<\/h2>\n\n\n\n

*#06# \u2013 IMEI Number<\/h3>\n\n\n\n

Our list begins with a code whose usefulness cannot be overstated, especially since it works on both Android and iOS phones. By using this code, you can instantly and\u2014most importantly\u2014reliably retrieve your phone\u2019s IMEI number. This is essential when purchasing a second-hand phone. Checking the IMEI number allows you to verify online whether the device you\u2019re buying might be stolen.<\/p>\n\n\n\n

*#07# \u2013 Device SAR Level<\/h3>\n\n\n\n

Typing this code into virtually any phone will display its SAR level. But what exactly is SAR?
All wireless devices, including smartphones that use radio waves (RF), emit electromagnetic radiation. Long-term exposure to strong RF waves may negatively affect human health. SAR (Specific Absorption Rate) is a globally accepted measure of the power absorbed per mass of human tissue.<\/p>\n\n\n\n

Different countries have different SAR limits. For example, the U.S. government uses FCC certification, which approves a SAR level of 1.6 W\/kg, while European countries adhere to CE certification, which allows up to 2.0 W\/kg.<\/p>\n\n\n\n

**04* \u2013 Quick PIN Change<\/h3>\n\n\n\n

A very handy code for quickly and easily changing your SIM card\u2019s PIN. Simply type the code according to the following sequence:<\/em>

<\/em>**04*oldPIN<\/em>*newPIN*newPIN<\/em><\/strong><\/p>\n\n\n\n

The new PIN must be entered twice, and each section of the sequence is separated by the * symbol.
This code works on both Android and iOS devices.<\/p>\n\n\n\n

#31# \u2013 Hide Your Phone Number<\/h3>\n\n\n\n

This code allows you to temporarily hide your phone number during a call. Just prefix the number you\u2019re dialing with #31#, and the recipient won\u2019t see your number\u2014even if they\u2019ve saved it in their contacts.

For example, to call 123 456 789 anonymously, type: #31#123456789.
<\/strong>
This is particularly useful when returning calls to unfamiliar numbers, suspecting they might belong to telemarketers. \ud83d\ude42<\/p>\n\n\n\n

*43# and #43# \u2013 Enable\/Disable Call Waiting<\/h3>\n\n\n\n

all waiting is one of the most essential features. It ensures you won\u2019t miss important calls, even while speaking with someone else. It notifies you of incoming calls with a beep sound, and the caller\u2019s number or name will appear on your screen.
While this feature can also be managed through your phone settings, entering *43# (to enable) or #43# (to disable) is much faster.<\/p>\n\n\n\n

*#21# \u2013 Check Call Forwarding Status<\/h3>\n\n\n\n

Every phone allows you to forward incoming calls to another number of your choice. This applies to voice calls, data, faxes, and even SMS.
Anyone with access to your phone can activate this without your authorization. So, if your phone is unusually quiet, it\u2019s worth typing this code to check if call forwarding has been enabled as a prank.<\/p>\n\n\n\n

And if it turns out call forwarding is active, here\u2019s how to resolve it.<\/p>\n\n\n\n

##002# \u2013 Remove Call Forwarding<\/h3>\n\n\n\n

Simply type this code into your phone, and all call forwarding settings will be erased.
Like the previous codes, this one works on both Android and iOS.<\/p>\n\n\n\n

#<\/em>#4636##<\/em> \u2013 Device Information (Android)<\/h3>\n\n\n\n

Typing this code reveals information such as the IMEI number, phone number, IMSI number, network region, roaming status, data network type, signal strength, and upload\/download speeds in KBPS. Additionally, this USSD code displays all user statistics.
Unfortunately, this code doesn\u2019t work on all Android devices. On some Xiaomi phones, for example, similar information can be accessed using the code #<\/em>#0000##<\/em><\/strong>.<\/p>\n\n\n\n

#<\/em>#225##<\/em> \u2013 Calendar Data (Android)<\/h3>\n\n\n\n

An interesting code that displays a summary of calendar data stored on your phone, including calendar groups and the number of events assigned to them.<\/p>\n\n\n\n

#<\/em>#4636##<\/em> (for Android) and 3001#12345#<\/em> (for iOS) \u2013 Field Mode<\/h3>\n\n\n\n

Our favorite code in this list.
It grants access to a hidden menu with detailed information about available networks and cell towers. This code provides in-depth insights into mobile networks, including RAT (Radio Access Technology), frequency bands, signal quality and strength, and other network-related metrics.<\/p>\n\n\n\n

With this USSD code, we conclude our list and begin preparing the next articles, which will be published soon.<\/p>\n","protected":false},"excerpt":{"rendered":"
