Have you ever noticed that calls to your number go to answering machine too quickly or do not reach you at all, although the phone is turned on? This could be a sign of a forwarding setup that redirects incoming calls to another number. In the world of mobile technology, this feature is useful if you are roaming or busy, but it can also become a tool for scammers.
There are several ways how to find out if there is redirection on Android. You can use hidden USSD codes that work on most devices, or look into the depths of your smartphone's system menu. Sometimes the settings are hidden under different names depending on the version of the shell installed by the manufacturer.
In this article we will analyze in detail all the verification methods. We will look at standard paths in the settings menu, universal commands for dialing a number, and specific nuances for different telecom operators. Understanding how this feature works will help you protect your privacy and ensure that no one is reading your missed calls for you.
Using universal USSD codes for verification
The fastest and most reliable way to check the forwarding status is to use special service commands. These codes send a request directly to the operator's server, bypassing the settings of the phone itself. This means that you will receive up-to-date information even if the smartphone menu displays incorrect data due to a software glitch.
To check the general status of all types of forwarding (when busy, when not responding, when unavailable) use the universal code *#21#. After dialing this combination and pressing the call button, an information window will appear on the screen. It will clearly indicate whether forwarding is active and to which number it is currently configured.
If you want to check specific conditions, there are more detailed commands. For example, the code #61# will show forwarding settings only for cases when you do not answer the phone. And the combination #62# will tell you where calls go if your phone is turned off or out of network coverage.
⚠️ Attention: Some telecom operators may block certain USSD commands or require confirmation via SMS before displaying information. If the code does not work, try adding a one and a hash at the end, for example
*#21*1#.
Remember that these commands work at the GSM/UMTS/LTE network level. Therefore, the result will be the same regardless of whether you use Samsung Galaxy, Xiaomi or any other brand. The main thing is the presence of a SIM card and a network signal.
Checking through the Android system settings menu
If you prefer a visual interface instead of entering numbers, you can find the forwarding settings directly in the phone menu. However, the path to them may differ depending on the version of Android and the manufacturer’s proprietary shell. In “pure” Android, which is used in smartphones Google Pixel or Motorola, the menu logic is as simple and intuitive as possible.
You need to open the “Phone” application, click on the three dots in the corner of the screen and select the “Settings” section. Next, look for the item “Accounts for calls” or immediately “Call forwarding”. The system may take a few seconds to poll the network, after which it will display the current status.
On devices with a shell One UI ot Samsung or MIUI ot Xiaomi the path may be a little longer. Often these settings are hidden in the general menu “Settings” -> “Applications” -> “Phone” -> “Forwarding”. It is important not to confuse this with call blocking, as these are different functions with different purposes.
If the “Forwarding” item in the menu is active (not greyed out), but when you press it nothing happens or an error appears, try restarting the device. This often solves problems with communication between the phone module and the operator's network.
In the settings menu you usually see four main types of forwarding:
- 📞 Always forward - all calls go to another number immediately.
- 🚫 If busy - forwarding works only when you are talking to someone others.
- ⏳ If there is no answer, the call is transferred if you have not answered the phone for a certain time.
- ✈️ If unavailable, it works when the phone is turned off or there is no network.
The interface may change with each firmware update. If you cannot find the item you need, use the settings search by entering the word “forwarding” or “calls.” This will save time and allow you to immediately go to the desired screen.
Table: Comparison of methods for checking redirects
To make it easier for you to choose the appropriate diagnostic method, we have compiled a comparison table. It will help you understand the advantages and disadvantages of each method depending on your situation and device model.
| Verification method | Data acquisition speed | Information accuracy | Dependency on the model |
|---|---|---|---|
| USSD code *#21# | Instant | High (data from the operator) | No (works everywhere) |
| Android settings menu | 1-2 minutes | Medium (can cache old data) | Yes (the interface is different) |
| Operator's personal account | Depends on the Internet | High | No |
| Call support | 5-10 minutes | Maximum | No |
As can be seen from the table, USSD codes are the most universal tool. They do not require an Internet connection and work even when the battery level is low, when launching heavy applications may be difficult.
However, if you want to not only check, but also fine-tune the wait time before forwarding (for example, increase it from 15 to 30 seconds), then the phone settings menu will give you more options than simple service codes.
Why there may be in the menu error?
Sometimes the phone displays the status “Not forwarded”, although in fact forwarding is active. This occurs due to desynchronization of the local settings cache and data on the operator’s side. Always double-check your doubts using the USSD code.
Specific settings for different telecom operators
Although GSM standards are the same for everyone, each telecom operator (MTS, Beeline, MegaFon, Tele2) may have its own characteristics in the implementation of services. Some tariff plans may include automatic forwarding to voicemail as part of the service package, and it can be difficult to disable it through the phone menu.
For example, for some providers, voicemail activation automatically includes forwarding “if no answer” or “if unavailable.” In this case, even if you disable this function on your phone, the call will still go to an answering machine, since the rule is set on the network side.
⚠️ Attention: The terms of service and the cost of call forwarding (especially in roaming) may change. Before activating or changing settings, check the tariffs in your operator’s official application or website to avoid unexpected charges.
To manage services through the operator’s website, you will need to log into your personal account. There, in the “Services” or “Call Settings” section, you will see a complete list of active redirects. This is the most transparent way of control, since you see exactly what is configured in your subscriber profile.
If you find an unknown number in the forwarding settings that you did not set, immediately disable this feature. This may be a sign that scammers are trying to use your number to intercept confirmation codes from banks or instant messengers.
☑️ Actions when someone else's forwarding is detected
How to disable forwarding once and for all
If the scan shows the presence of unwanted redirects, it must be disabled. The easiest way to do this globally is to use code ##002#. This command will cancel all types of voice, SMS and data call forwarding, returning the settings to factory defaults.
After entering the command and pressing the call button, you will receive a message indicating that all forwarding rules have been successfully deleted. This action is safe and will not affect other settings on your phone, such as contacts or installed applications.
You can also disable forwarding selectively through the settings menu. Go to the call control section, select the type of forwarding (for example, “If busy”) and click the “Disconnect” or “Turn off” button. The system will send a request to the operator, and after a few seconds the function will be deactivated.
It is important to understand the difference between disabling call forwarding and blocking incoming calls. Blocking prevents calls from certain or all numbers, while disabling call forwarding simply forces the phone to call you directly rather than forwarding the call to another subscriber.
The code ##002# is a universal “reset” for all forwarding settings. Use it if you are not sure which rules are currently active on your number.
Common problems and ways to solve them
Sometimes users are faced with a situation where the phone writes “Request error” or “Connection failed” when trying to change forwarding settings. Most often, this is due to a lack of network signal at the time the request was sent or temporary problems on the operator’s side.
Another common problem is the inability to disable forwarding to voicemail. In this case, standard codes may not work, since the service is strictly tied to the tariff. The solution is to contact the operator's support service with a request to completely disable the Voicemail service.
It is also worth mentioning the influence of third-party applications. Some call apps (Truecaller, Call Recorder and analogues) may have their own forwarding or blocking settings that conflict with the system ones. If you cannot find the reason, try temporarily disabling such applications.
Do not forget that in Do Not Disturb mode the phone may not ring, creating the illusion of forwarding. Check the settings of this mode to make sure that calls are not blocked programmatically by the device itself.
Can I find out who set up forwarding to my number?
Technically, you can only see the number that is being forwarded to, but not the name of the owner of this number or the person who entered it. If the number is not familiar to you, this is a cause for concern. The telecom operator can provide additional information only at the request of law enforcement agencies.
Is there a fee for checking with *#21# and other codes?
In most cases, checking the status of services via USSD codes is free. However, if the code initiates some action (for example, a trial subscription), you may receive an SMS confirmation. Always read the text on the screen carefully before confirming.
Do these codes work if the phone is locked?
Yes, USSD codes can be entered from the lock screen by pressing the "Emergency Call" button. To complete the request, you do not need to unlock the device by entering a password or fingerprint; a SIM card and a network are sufficient.
What to do if the code ##002# does not disable forwarding?
If the universal code does not work, it means that the service is activated on the operator’s side as a mandatory part of the tariff or an additional option. In this case, only a call to the support service or a visit to a communication salon will help.
Does forwarding affect Internet speed?
No, forwarding voice calls does not affect the speed of mobile data or the operation of applications. These are different data transmission channels. However, SMS forwarding may affect the receipt of confirmation codes, which is critical for the security of banking applications.
