Checking SMS app settings and spam filters
The first thing you need to do is look into the standard messaging app. Modern shells Android (MIUI, One UI, EMUI) have built-in anti-spam algorithms, which sometimes work too aggressively. They can automatically place short codes in a separate folder without notifying the owner.
Open the application Messages and find the settings menu. It is usually hidden under an icon with three dots or a gear. Find the section called Spam protection or Blocking numbers. Inside this menu you will see a list of blocked contacts. If there is a number 900there, just remove it from the list.
⚠️ Attention: In some firmware (for example, Xiaomi) The spam filter works at the system level. If you do not find the number in the messages application, check the Security application → Blacklist.
It is also worth checking the notification settings for a specific conversation. Go to correspondence with the bank (if there is one) and click on the three dots in the corner of the screen. Select item Chat settings or Notifications. Make sure the switch Show notifications is active. Sometimes users accidentally mute or hide the content of notifications on the lock screen.
If you have a third-party messenger installed (for example, Textra or Handcent), check the settings in it, as system settings may not apply to third-party software.
Working with the black list in the phone settings
In addition to the settings of the SMS application itself, the number can be blocked at the system level or through third-party antiviruses. If you use security software like Dr.Web or Kaspersky, their built-in modules could recognize the short code as suspicious.
To check, go to the general settings of your smartphone. The path often looks like this: Settings → Applications → Application management → Messages → Permissions. Make sure the app has permission to read and send SMS. Without this functionality receiving messages is impossible.
If you use the services of an operator to block spam (for example, "Antispam" from MTS or Beeline), check the operator’s personal account. Sometimes short bank numbers fall under operator security filters. To exclude this option, temporarily disable the spam filtering service in your personal account mobile provider.
- 📱 Check the "Blocked numbers" section in the call settings.
- 🛡️ Open your antivirus and look at the message blocking log.
- 📞 Make sure that number 900 is not added to contacts marked as "Spam".
Resetting network settings and re-registering on the network
Sometimes the problem is of a technical nature and is associated with freezing of network services on the device. The phone may “think” it is roaming or in an area with poor coverage, even if you are at home. In this case, messages from short numbers may be lost along the way.
The easiest way is to switch the network mode. Go to Settings → Connections → Mobile networks. Change the mode from 4G/3G/2G to 2G only, wait a minute, and then return it back. This will force the modem to reconnect to the tower and update the SMS delivery settings.
If this does not help, try removing the SIM card. Turn off the phone, remove the tray, wipe the SIM card contacts with a soft cloth and insert it back. After turning on the phone, wait until the network is fully loaded. This method often solves problems with the delivery of service messages from Sberbank.
Settings → System → Reset settings → Reset Wi-Fi, mobile data and Bluetooth settingsThis command (or a similar item in the menu) will clear the network settings cache without affecting your personal data. This is a secure procedure that eliminates access point APN configuration conflicts that sometimes affect SMS delivery gateways.

Interaction with the telecom operator and Sberbank
If the phone settings are in order, the problem may be on the operator’s side. The Mobile Banking service may be disabled by your telecom operator if you run out of money in your account or if you recently changed your tariff to one that does not support short numbers.
Call your operator's support line. Ask to check whether there is a ban on receiving messages from short numbers. Also check whether the service is active SMS informing. The operator can see the delivery status of the latest messages, which will help to understand whether they are blocked at the entrance or simply not sent by the bank.

| Beeline | *110*181# | 0611 |
| MegaFon | *105*005# | 0500 |
| Tele2 | *155*611# | 611 |

Specifics of working with Dual SIM and eSIM
Owners of phones with two SIM cards often encounter confusion. Messages from the bank may arrive on one SIM card, and you are checking another. Or, in the default settings for SMS, the card on which the Mobile Bank is connected is not selected Mobile bank.
Go to the SIM card settings. Make sure you select the correct line to send and receive messages. In some versions of Android, you can assign a specific SIM card to a specific contact. Try saving the number 900 to your contacts and linking it to the desired SIM card manually.

Radical methods: resetting and replacing SIM
If all else fails, the SIM card itself may be damaged. Over time, the chip can degrade, especially if the card is old and hand-cut from Mini/Micro to Nano format. In this case, the phone sees the network, but cannot correctly process service SMS.
The solution is to replace the SIM card with the operator. It's free and takes 10 minutes in the salon. The number and tariff will remain the same, but you will receive a new chip. After replacing, be sure to restart your phone and check for messages.
As a last resort, you can completely reset your phone to factory settings. This will delete all data, so be sure to make a backup. Go to Settings → System → Reset → Delete all data. This will eliminate the influence of any hidden system errors or malware blocking messages.
⚠️ Attention: Before replacing the SIM card, make sure that you remember the security word or have access to Sberbank Online to confirm the number. Linking a new chip may require re-authorization in the bank application.
When replacing a SIM card, ask the operator to immediately check the delivery of a test SMS from the bank in the salon. This will save you time if the problem was in the chip.
