Change MAC addresses On a smartphone, changing the MAC address is a procedure that may be necessary to bypass network restrictions, test security, or resolve connection issues. However, not everyone knows that this process has its own nuances depending on the operating system, device model, and even firmware version. Unlike on computers, where changing the MAC address often comes down to a few clicks in the network card settings, on mobile devices things are more complicated: manufacturers limit such options, and some methods require root rights or special utilities.
In this article, we will look at how to change the Wi-Fi MAC address on phones running Android And iOS, including workarounds for unrooted devices. You'll also learn why some networks block devices by MAC address, the risks of changing it, and how to restore the original address if something goes wrong. Important: On devices with Qualcomm chips (e.g., Snapdragon) and MediaTek, MAC address change algorithms may differ significantly, which affects the method you choose.
What is a MAC address and why should you change it on your phone?
MAC address (Media Access Control) is a unique identifier for a network interface that is assigned to a device during manufacturing. It consists of 6 bytes (48 bits) and is typically written in the format XX:XX:XX:XX:XX:XX, where the first three bytes identify the equipment manufacturer, and the last three are the unique device number. Unlike an IP address, which can change when connecting to different networks, a MAC address remains constant... until it is manually changed.
Reasons to change the MAC address on your phone:
- 🔒 Bypass MAC blocking — Some public Wi-Fi networks (hotels, airports, educational institutions) restrict access to a list of allowed addresses.
- 🛡️ Increasing anonymity — hiding the real device identifier from trackers in networks with traffic monitoring.
- 🔧 Testing network policies — checking how the network reacts to the connection of "new" devices.
- 📡 Troubleshooting connection issues - Some routers cache MAC addresses and may conflict when reconnecting.
However, there is a downside: changing the MAC can lead to unstable Wi-Fi operation, especially if the new address conflicts with another device on the network. Furthermore, some applications (such as banking apps) may interpret a MAC address change as a sign of hacking and block access.
⚠️ Attention: In networks with MAC authentication (for example, corporate or educational), frequent address changes can lead to automatic device lock security system. Before changing any of these, please check with your network administrator.
Is it possible to change the MAC address without rooting an Android device?
On most modern smartphones Android (version 8.0 and above) manufacturers block the ability to change the MAC address without root accessThis is due to security policy. Google, which limits modification of system parameters. However, there are several workarounds:
1. Temporary shift through the "Developer"
Some devices (eg Xiaomi, Samsung (with Exynos processors) allow you to change the MAC address through the developer menu. To do this:
- Activate
Developer mode(Click 7 times onBuild numberin the phone settings). - Go to
Settings → System → Developer Options. - Find the option
Non-persistent MAC address(non-persistent MAC) orWi-Fi MAC address.
2. Applications without root
There are utilities like Mac Changer or WiFi Mac Changer, which promise to change the MAC without root access. However, they only work on older versions of Android (up to 7.0) or on devices with certain Wi-Fi chips (e.g., Broadcom). On new smartphones, such apps most often simply display a random address without changing the real one.
⚠️ Attention: Applications requesting root access to change the MAC may contain malicious code. Before installing, check the developer's reviews and reputation on 4PDA or XDA Developers.
Step-by-step instructions: changing the MAC address on a rooted Android device
If your device has root access, the process of changing the MAC becomes easier, but still requires caution. Below is a universal method that works on most firmware (including LineageOS, MIUI, One UI).
Step 1: Install Terminal and Check Current MAC
Download the app Termux or any other Android terminal. Enter the command:
ip link show wlan0Or an alternative (if the first one didn’t work):
cat /sys/class/net/wlan0/addressIn the response you will see the current MAC address of the interface. wlan0 (or eth0 for Ethernet, if available).
Step 2: Disable Wi-Fi and Change MAC
Execute the commands in order:
suifconfig wlan0 down
busybox ifconfig wlan0 hw ether XX:XX:XX:XX:XX:XX
ifconfig wlan0 up
Where XX:XX:XX:XX:XX:XX — the new MAC address. For example, 00:1A:2B:3C:4D:5E. Important: the first 3 bytes (for example, 00:1A:2B) must correspond to the actual manufacturer (you can look in the database OUI on the IEEE website).
Step 3: Check the changes
Repeat the command from Step 1. If the address has changed, the procedure was successful. If not, try the alternative method using a file. /data/nvram/APCFG/APRDEB/WIFI (relevant for devices on MediaTek).

How to change MAC address on iPhone (iOS)
On devices Apple (iPhone, iPad) The situation with changing the MAC address is even stricter than on Android. The company completely blocks modification of the hardware address at the software level, and no app from App Store won't be able to change it. However, there are two nuances:
1. "Private MAC Address" in iOS 14+
Starting from iOS 14Apple added a feature Private Wi-Fi Address (Private Wi-Fi Address) which is automatically generated random MAC for each new network. This isn't a complete replacement for the original address, but it does allow you to hide the real identifier from the router. To enable:
- Go to
Settings → Wi-Fi. - Click the "i" icon next to the connected network.
- Activate the option
Private address.
2. Bypass via DNS spoofing
Some advanced users use DNS servers with MAC spoofing support (e.g. NextDNS), but this doesn't change the device's actual address; it only masks it for certain services. To completely change the MAC address on an iPhone, you'll need jailbreak (system hacking), which voids the warranty and creates security risks.
⚠️ Attention: Enabling the function Private address This may cause problems on networks where authentication is tied to the MAC address (for example, some hotels or corporate Wi-Fi networks). In this case, disable it before connecting.
Risks and consequences of changing the MAC address
Before changing your MAC, consider the potential negative consequences:
| Risk | Consequences | How to minimize |
|---|---|---|
| Network blocking | The network administrator can ban a new MAC if he deems it suspicious. | Use addresses from reputable manufacturers (eg. Apple, Samsung). |
| Unstable Wi-Fi | Conflicts with other devices on the network or connection errors. | Reboot your router after changing MAC. |
| Loss of warranty | Damage to system files (for example, due to root) may be grounds for denial of warranty repairs. | Use non-root methods or restore the original MAC before contacting service. |
| Problems with banking apps | Some banks block access if a modified MAC is detected (considered a sign of hacking). | Please return to the original MAC before using financial services. |
Owners of devices with Knox (For example, Samsung Galaxy With Samsung Knox). Changing system parameters may trigger a trigger Knox Void, which will make it impossible to use secure containers and some corporate functions.
How to restore the original MAC address
If you encounter problems after changing your MAC address (for example, your device stops connecting to the network or is blocked by an administrator), you can restore the original address in several ways:
On Android with root:
- 🔄 Reboot your phone - on some devices, the MAC resets to the original after a reboot.
- 📝 Enter the following command in the terminal:
suifconfig wlan0 down
ifconfig wlan0 hw ether [ORIGINAL_MAC]
ifconfig wlan0 up - 🔧 If your MAC is stuck, delete the file
/data/nvram/APCFG/APRDEB/WIFI(only for MediaTek!) and reboot your device.
On Android without root:
- ⚙️ Reset network settings in
Settings → System → Reset → Reset Wi-Fi settings. - 📱 Update your firmware - sometimes updates reset temporary MAC changes.
On iPhone:
- 🔄 Turn the feature off and on again
Private addressin the Wi-Fi settings. - 📵 Forget the network (
Settings → Wi-Fi → "i" → "Forget this network") and reconnect.
If none of the methods worked, there is a last resort - factory resetPlease note that this will delete all data from your device, so make a backup beforehand.
Alternative ways to bypass MAC blocking
If changing your MAC address fails or is too risky, consider alternative methods:
1. Using a VPN
VPN services (eg ProtonVPN, NordVPN) mask your real IP and some network data, which can help bypass some restrictions. However, this is no substitute for changing your MAC address in networks where blocking occurs at the router level.
2. Connecting via another device
If your phone is locked, connect to Wi-Fi via a laptop or tablet, and then share the Internet with your phone via USB or Bluetooth (modem mode).
3. Changing IMEI (extreme case)
On some Android devices you can change IMEI (unique identifier of the communication module), which sometimes resets network restrictions. However, this is illegal in many countries and can lead to serious problems with your carrier.
4. Contacting the network administrator
If the blocking occurred on a corporate or educational network, it's easier to contact the IT department and ask them to add your MAC address to the whitelist. This often resolves the issue without any technical intervention.
What happens if I use an incorrect MAC address?
If the new MAC address is in an invalid format (e.g., contains invalid characters) or the first 3 bytes do not match any manufacturer, the device may lose connection to the network. In the worst case, this will lead to hardware failure of the Wi-Fi module, requiring reflashing or repair. This is especially relevant for devices with chips. Qualcomm (For example, Snapdragon 8xx), where incorrect settings can damage the module's configuration files.
FAQ: Frequently asked questions about changing your phone's MAC address
Is it possible to change the MAC address on a phone without root or a computer?
On most modern Android devices (version 10+) - no. Some models are an exception. Xiaomi And Samsung With Exynos processors, there's an option to change the MAC address in the developer menu. On iPhones, changing the MAC address is impossible without jailbreaking.
Why doesn't my phone connect to Wi-Fi after changing my MAC?
Possible reasons:
- The new MAC conflicts with another device on the network.
- The address is not in the correct format (e.g. contains letters outside the AF range).
- The router blocks "unknown" MAC addresses.
Try to return the original MAC or use the address from another known device (eg. 78:31:C1:XX:XX:XX For Apple).
How do I find out what the original MAC address was?
The original MAC is usually listed:
- On the device box (on the sticker with the serial number).
- In the phone settings:
Settings → About phone → General information → Wi-Fi MAC address(before change). - In the router menu, if the phone has previously connected to the network (section
DHCP Clients ListorConnected Devices).
Is it legal to change your MAC address?
Technically, yes, it's not illegal. However, if you use MAC address changer to bypass internet charges (for example, at a hotel or on a plane) or gain unauthorized access to the network, it could be considered fraud or illegal entry (Depending on jurisdiction). In corporate networks, such actions may result in disciplinary action.
Is it possible to change MAC on phones with eSIM?
Availability eSIM does not affect the ability to change the Wi-Fi MAC address. These technologies relate to different modules: eSIM The MAC address is responsible for mobile communications (3G/4G/5G), while the MAC address is responsible for identification in local networks (Wi-Fi, Bluetooth). The methods for changing the MAC address remain the same as described above.
