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.
Does roaming make internet abroad free?
No, no. The command changes the availability of the service, and the cost and limits are determined by your offer and country. Check your roaming and data plans before you travel.
