Swisscom Support

If you have questions about your subscription or the corresponding invoice, please do not contact Swisscom directly.

Some of the call center staff are not informed about the promotion via Projekt Neptun and will refer you back to us.

Please klick the "Need Help?" button on the right and write us an email with the mobile number concerned and an email address where we can reach you. We will forward your request to the responsible team at Swisscom. Swisscom will then get back to you after processing your request. 

Please note that we have no influence on the processing time or Swisscom's systems and can only assist you, but cannot resolve your request personally. Thank you for your understanding.
