This is the cause and easy way to overcome the Telegram Failure to Login!

On Monday, June 9, 2025, many telegram users in Indonesia complained about difficulties when trying to log in using a new number. Although the number is correct, the telegram application does not send a verification code, and the login screen looks unresponsive. This triggers many talks on social media, especially Twitter, where some users associate this problem with the presence of bugs or technical problems in the telegram system.

Constraints cannot login to telegram not only caused by a signal or poor network. There are several related technical factors that might be the cause, especially when users change their mobile numbers. Here are some of the factors that need to be considered:

1. Verification code is not sent
   Telegram uses a code delivery system via SMS or telephone. If the new number has not been recognized by the system or if the user too often asks for the code in a short time, code delivery can be blocked as a preventive measure to prevent spam.

2. Cooldown because you try to login too often
   Telegram applies a security system that limits repeated login experiments in a short time. If the login is tried too often, the system will impose a waiting time (cooldown) that can last between 24 to 48 hours.

3. The application has not been updated
   The use of the old version of the telegram application can also be a problem. Bugs in that version can interfere with the process of sending the verification code or even causing the application to be unstable when logging in.

4. The cellphone settings are not supportive
   Some settings in the cellphone, such as power saving modes or blocking background data, can hamper telegrams in receiving a verification code well.

To solve the login problem, users can take the following steps:

1. Update Telegram Applications
   Ensuring that the telegram application is always updated to the latest version is very important. Reform usually contains bug improvements that affect application functions.

2. Use the correct international number format
   To enter mobile number, use an international format. Users in Indonesia need to add a +62 prefix and eliminate zero in front of the new number.

3. Clean the cache and application data
   Through settings, users can delete cache and telegram application data. This helps to prevent the technical problems of the previous login session that may be left.

4. Check and re -set the application permit
   Make sure the telegram has the necessary permits, such as access to SMS, telephone, and background data. Also deactivate power saver to ensure the application can run smoothly.

5. Wait for cooldown time
   If you have tried to log in too often, patient is the key. Wait between 24 to 48 hours before trying to log in again.

6. Use an alternative device or platform
   If the login still fails on the cellphone, try accessing the telegram through the browser on the web.telegram.org or the desktop telegram application. However, remember that the verification code will only be sent to the previously connected device.

By following the steps above and waiting for the cooldown time, users can usually access their telegram accounts in 1-2 days. If the problem continues, it is important to re -check all the steps taken to ensure that there are no missed arrangements.

Login constraints to telegram with new numbers can cause concern, especially if the account stores important information. However, with the right understanding of the causes and following the recommended steps, the problem can be overcome. If all efforts have been made, but the problem remains, users can contact the Telegram Support Team through their official website or social media to get further assistance.
