 Current note

30.04.2024: The porting of SIM cards, additional SIM cards and eSIM is complete. The business phone team of the ZID and the provider Drei are currently finalising the last technical adjustments to the system. The business phone service will be available as usual shortly. 

Provider, schedule

  • The University of Vienna's new business phone provider is Hutchison Drei Austria GmbH (Drei for short).
  • For technical reasons, business phone contracts can only be registered or changed again from 2 May 2024. The ZID asks for your understanding.

Service

  • Reception and coverage are of course guaranteed at all locations of the University of Vienna, even at exposed or remote locations.
  • All SIM cards will have access to the 5G network in the future.
  • Voice-over-Wi-Fi and Voice-over-LTE also work with an additional SIM
  • All SIM cards from the new provider allow up to 300 Mbit/s download and 50 Mbit/s upload. The previous contract allowed a maximum of 40 Mbit/s download and 10 Mbit/s upload for most SIM cards. 

Phone numbers

  • The business mobile phone numbers in the format +43-664-817xxxx have been ported.
  • The university's internal speed dialling numbers remain unchanged:

    • Business mobile phone to business mobile phone or u:phone device to u:phone device: dial desired u:phone extension.
    • Business mobile phone to u:phone device and vice versa: dial 90 + u:phone extension.

  • The old business phone numbers of the University of Vienna in the format +43-664-60277-u:phone extension can still be reached by phone, but not anymore by SMS.

Kundenzone (customer zone)

Die Drei Kundenzone (Drei customer zone) was primarily developed for private customers. You can set up call forwarding or activate voicemail there. User guide Using Drei Kundenzone (in German)

Specific adjustments have been made to the Kundenzone for the University of Vienna. For example, all paid additional functions are deactivated

Some of the information displayed relates to the contract that the University of Vienna has signed with Drei, and is not related to your individually selected basic tariff. This includes, for example, the Tarif (tariff) and Produkt (product) details mentioned in the Kundenzone.

All functions that require to enter the Kundenkennwort (customer password) are reserved for the ZID business phone team.

Fair-use principle

The new basic tariffs are designed as package prices based on a fair-use principle, regardless of usage.

This means that there is a reference value for users, but no fixed upper limit for usage. Even if you exceed the fair-use reference value occasionally, you will not incur any additional costs in Austria and when travelling throughout the EU. The ZID will only contact you if you exceed the reference value for 3 consecutive months in order to find a more suitable tariff together.

 Note

Tariffs based on the fair-use principle are more convenient for users than billing for unit prices or packages. However, fair-use tariffs only work in the long term if the tariff also matches the usage behaviour. Use the Drei Kundenzone app (download from the Play Store or App Store) or the Drei Kundenzone on the web to keep track of your usage. 
 

Tariffs

All new basic tariffs include 3,000 free minutes for voice calls and 1,000 SMS/MMS. 4 tariffs also include a monthly data volume depending on the price. Free minutes, SMS/MMS and data can be used in Austria and when travelling throughout the EU: EU roaming (voice calls, data, text messages) is included as standard in the new basic tariffs.

Additional costs only arise

These additional costs are charged according to usage. In future, the tariffs for this will be significantly cheaper than before. 

For long calls abroad, the ZID recommends u:phone as the cheapest alternative. 

Billing

Your tariff has been automatically transferred by the ZID to one of the new basic tariffs from Drei based on the packages formerly booked with A1. In short time you can see which tariff has been assigned to you in the Servicedesk and change the tariff if desired. 

For cost centre managers, only the amount charged will change. You do not have to do anything. 

  • For April 2024 cost centre managers will receive 2 separate invoices: one from the previous provider A1 and one from the new provider Drei.
  • For technical reasons, the first invoice from the new provider will probably arrive a little later than usual. The ZID asks for your understanding.

Porting

The porting of the business phone numbers to the new provider is complete.

eSIM

If your device supports eSIM, you can use your business phone with eSIM. User guide Using a business phone with eSIM
