Activate contract (Postpaid)

You can order the activation of your SIM card in just a few steps on our User Portal.

Here is an example for Iridium GO! Postpaid:


  • Log in to sim-ticket.de. If you do not have access yet, you can subscribe via register now.
  • Click activation/reload in menu.
  • Select Iridium as the satellite system.
  • Select GO! Postpaid as the card type.


  • Here you select the tariff plan that you want to activate on your SIM card.


  • On this page you enter your SIMID and the requested activation date. You will find the SIMID in your documents or printed directly on the SIM card.
  • If you have several SIM cards, the field title of your choice is useful. This makes it easier for you to find tickets again.
  • The order confir­mation and also the confir­mation of the actual reload/activation will always be sent to you by e‑mail. On this page you can specify additional email addresses for these notifi­ca­tions and also specify that you will receive an SMS to your cell phone and/or satellite phone.


  • In the last step, you will see an overview of all data for the actual activation.


  • You will also receive the ticket data as an email for confir­mation.


  • Under my tickets you have the possi­bility to check your actual activation at any time.
  • Up to the date of activation, you can also make changes there: Select another tariff plan, change the activation date, etc.


  • On the activation date, the tickets are processed by us first in the morning. A reload is normally available at 9:30AM local time in Darmstadt latest.
  • When the SIM card is activated, the satellite phone number is assigned directly by the network operator. You will receive your phone number by email together with the security codes.
  • We will be happy to send this mail to up to three email addresses, which you can specify in step 3.
