Cancel your mobile phone contract with Smartmobil in writing

If you want to be absolutely sure, you can also cancel your contract in writing by post:

• Send the signed letter of termination to: MS Mobile Services GmbH, Smartmobil customer service, Wilhelm-Röntgen-Straße 3, D-63477 Maintal
• The number of the service hotline is: 01805 669 010.
