Basic balance and Lyca package are checked separately
*131# refers to the funds of the main account, *137# is specified by the operator for information about the package. The name of the package should be taken from the cabinet or the purchase confirmation: similar national, international and long-term packages have different conditions. Here are the versions confirmed by the current page; the remaining generations still require comparison with documents.
How to send a command safely
- Find the exact name of the offer in the operator's app, contract, or purchase receipt. Select your service type and rate below.
- Open the "Phone" app, select the desired SIM with two numbers and enter the code in full. In the templates, replace TELEKOD, KOD or number with your values - you do not need to send words.
- Press the call and wait for the answer. For the connection command, first read the price, duration and renewal rules.
- Do not send the paid command again if the confirmation is delayed: check the active services in the cabinet.

If the command did not work
Check the selected SIM, the accuracy of the characters, the number registration and the network access. The error message does not prove that the service is not supported: the reason may be a different tariff generation, an unavailable package or a temporary failure. Save the text of the reply without personal data and check the terms of your offer in the cabinet. Do not replace the code with a random command from another operator.
Code 321 is a USSD?
No, no. It's a short phone number. USSD templates in this table have an asterisk and a grid; phone numbers do not send commands as such.
Completeness and official sources
Do not confuse the balance of the main account (*131#) with the packet and data check (*137#). Numbers 321 and the international support line are phone numbers, not USSD.
Public commands are documented; the complete historical matrix of all generations is not confirmed. No SIM check was performed.
Date of documentary verification: 11.10.2026. Lack of confirmation does not mean incompatibility. An archive document does not in itself prove the continued service of a tariff.
