Mobile phone

With this service, official mobile phones can be requested from the HRZ with a contract tailored to requirements from the DFN framework contract of Vodafone GmbH.

Note on the changeover:

As soon as you have inserted your new SIM card, the porting is complete. No further action is required. This means that you do not need to activate the card as described in the enclosed letter from Vodafone.

The TU Darmstadt has joined the DFN (German Research Network) Mobilfungkrahmenvertrag. As of 01.06.2023, the contractual partner is therefore no longer Telekom, but Vodafone.

For all mobile phone contracts that were ordered and provided via the HRZ, the provider change from T-Mobile to Vodafone must therefore be carried out.

You can find out how to do this in the instructions for changing providers (opens in new tab) .
