Activation of the 1Unibox
To use your 1Unibox as the default voicemail, please copy the displayed GSM code in your phone app and press dial. You can find the GSM code in the settings (top left icon) in the menu item Voiceboxnumber.
You will receive a confirmation if the operation was successful.
Please note that the use of the 1Unibox, depending on the provider or tariff, may incur additional call charges. This is especially important during active roaming outside the EU.
Since the message length is automatically limited to 3 minutes, no high additional costs may occure.
