Changing a phone or losing a SIM card often causes a temporary lack of access to financial instruments, which creates discomfort in everyday life.

However, modern technologies make it possible to solve this issue remotely, using only mobile application a new smartphone.
The procedure for changing a number in the Sber ecosystem is as automated as possible, but requires the fulfillment of a number of security conditions to protect your funds. It is important to understand that simply entering new numbers in the profile settings will not be enough - the system will require confirmation of ownership of the new device and SIM card. In this article, we will analyze in detail the algorithm of actions, possible pitfalls and ways to bypass typical errors when transferring access.
Before taking active steps, make sure that your new SIM card has already been activated and installed in the smartphone from which you will log in.

If you have forgotten your access code, restoring it will take longer and require additional steps. SberBank Online, since in some scenarios the system may require it for identity verification. If you forget your passcode, recovering it will take longer and require additional steps.
Preparation for changing your number and necessary conditions
Successful completion of the procedure directly depends on preliminary preparation, which minimizes the risk of technical failures. The first thing you will need is a stable Internet connection, as the application will exchange encrypted data with the bank server in real time. An unstable signal can interrupt the authorization process, and the procedure will have to start again.
The second key point is having valid access to your personal account or knowing your credentials. If you have the ability to log into the application using your old number (for example, via Wi-Fi), this will greatly simplify the task. Otherwise, the system will use biometrics or passport data for identification, which requires having the document itself on hand.
Make sure that the new phone has the latest version of the application from the official Google Play store or AppGallery, as older versions may not support new security protocols.
The third aspect is the state of the account itself. Make sure that there are no temporary blocks or restrictions imposed by the security service on your profile. It is also worth checking whether your passport has expired in the bank database, as this may become a formal obstacle to changing contact information.
Step-by-step guide: logging in and navigating the application
We begin the process directly by launching the software on your device running the operating system Android. Open the application icon and click the “Login by password” or “Login by fingerprint/face” button if biometrics have already been configured previously. The system may report that the phone number does not match the registered one - this is a normal reaction that we will correct.
If you are logging in for the first time from a new device, the application will prompt you to enter a phone number. Enter the new number to which you want to transfer access. After this, SMS confirmation codewill be sent to the screen. Enter the resulting numbers in the appropriate field. At this stage, the device is initially linked to the SIM card.
- 📱 Open the application and select the password login option.
- 🔢 Enter a new phone number in the authorization field.
- 📨 Wait and enter the code from the SMS message.
- 🔐 Enter the password for your personal account or use biometrics.
After successfully entering the password, the system may request login confirmation via push notification to another trusted device, if available. If you don’t have another device or don’t have access to it, select the “Verify with code from SMS” or “Verify at ATM” option if the system offers such a choice. To completely change the number in the settings, you will need to go to your profile.
☑️ Check before entering
Changing the number in the user profile
After you have successfully logged into the application from a new number, you need to officially update the contact information in your profile so that all notifications and codes are received correctly. To do this, go to the main menu, usually indicated by a profile icon or your photo in the top or bottom left corner of the screen. Select “Profile” or “Settings.”
In the menu that opens, find the “Contact Information” section or just a line with your current phone number. Click on the edit icon (pencil) or on the number itself. The system will prompt you to change your phone number. Enter the new number again for verification and click the “Save” or “Change” button.
⚠️ Attention: Changing the number in your profile may take from a few minutes to 24 hours, depending on the load on the bank’s servers. During this period, confirmation codes may arrive on both numbers or not at all.
It is important to note that after changing the number in your profile, old phone number will no longer be linked to your account. This means that whoever gains access to your old SIM card will not be able to log into your client bank. This is an important security measure to prevent fraud.
What to do if the edit button is inactive?
If the phone number field is gray and not clickable, this means that the change is only possible through a bank employee or ATM. This often happens when there are special conditions of service or security restrictions.
Confirmation of a transaction through an ATM or terminal
In some cases, especially when changing the region or suspicious activity, the security system will require additional confirmation through a physical Sber device. This could be an ATM or a self-service terminal. Find the nearest device that supports card processing and facial recognition.
Go to the ATM and select the “Login by QR code” or “Login by card” option on the screen. If you have a card, insert it and enter your PIN. If you don’t have a card with you, many modern models support login using facial biometrics. After entering the menu, select “Mobile bank, Internet and television.”
| Action | Description | Required tool |
|---|---|---|
| Authorization | Entering the service menu | Card or Face |
| Selecting a service | Searching for a number change point | Touch screen |
| Entering data | Dialing a new phone number | ATM keyboard |
| Receiving a code | Entering a code from SMS | New phone |
Follow the instructions on the device screen. You will be prompted to enter a new phone number. After entering, an SMS with a confirmation code will be sent to the specified number. Enter the code in the terminal. After a successful operation, the ATM will issue a receipt confirming the number change, which is recommended to be kept until the mobile application is fully tested.
Solving common problems and errors
Users often encounter technical difficulties when changing their number. One of the most common errors is “Invalid verification code.” This can happen if your phone has a third-party spam blocking application that hides SMS from the bank. Check your Spam folder or temporarily disable the blocker.
Another common problem is an error connecting to the server. This often happens when using Wi-Fi networks that require authorization through a browser. Try switching to mobile data (4G/5G) and try again. Also make sure that the date and time settings on your smartphone are set to “Auto” mode, since time desynchronization disrupts the operation of SSL certificates.
If the application writes that “The number is already registered to another client,” this means that you previously issued a SIM card with your data, but did not unlink it from the old account, or the SIM card was re-issued by the operator and went to another person. In this case, you will need to call the contact center or visit the office.
⚠️ Attention: The application interface and menu layout may vary slightly depending on the version of the Android operating system and the model of your smartphone.
Security measures after changing the number
After successfully changing the number, it is extremely important to check the security settings so that make sure that only you have access to the account. Go to the "Security" section in the application profile and view the list of devices from which you are logged in. If you see unfamiliar gadgets, immediately click “Exit.”
It is recommended to set or update the PIN code to enter the application itself if you use quick login. Also check the limits on transfers and payments - after changing the number, they may be temporarily reduced by the security system until the new usage habits are fully verified.
Changing a number in the application automatically unlinks the old number from all bank services, making it impossible to log in through it without additional recovery procedures.
Do not forget that mobile banking is the key to your finances. Never share SMS codes with third parties, even if the caller introduces himself as a bank employee. Real employees never ask for confirmation codes or full card details.
