General

  • Will I get a new SIM card?

    If you want to continue using the internal telephone number privately, you will receive your new private SIM card from your new private provider. We recommend visiting the shop of your new private provider because there you can, among other things, have private data stored on the previous SIM card transferred to the new private SIM card in a straightforward manner.

    A new business mobile phone SIM card will only be available if you change your provider.

  • Do I need a second smartphone?

    Current smartphone models often have dual SIM. This means that with these models you can use both your business mobile phone SIM card and your private SIM card with just one device.

  • How can I use two phone numbers with one device?

    A device with dual SIM function is ideal for this purpose. In dual SIM devices, two SIM cards and thus also two separate phone numbers can be used in the same network or in different networks.

  • How do I know if I have a device with dual SIM function?

    Android and other devices

    The function has been available on Android devices for some time and is already built into many models. The function of a second SIM card is always displayed in the settings of your device. Depending on the version of the operating system, you will find it under Settings under the following or similar category: Network, Network and Internet or Connections and there in the section SIM Cards, SIM Card Management or Mobile Communications.
