10.1.2 Travel SIM Number
If you select Activate SIM Card in the main menu, the AMC+ uses this number to communicate to
the AMCC that a new SIM card has been inserted. If the number of this SIM card is configured for
your User Account on the AMCC, your new SIM card will be activated and you will be able to take
advantage of the features of the AMC Solution.
Advantage of Travel SIM
All of the services offered by the AMC+ are exclusively available for configured users. However, some
users might have several SIM cards, mostly for taking advantage of lower tariffs in different countries.
It is possible to configure up to ten cell phone (SIM card) numbers per user, but only one at a time will
be "active".
How it works
A call to Travel SIM number is placed and hung up immediately. This guarantees that the call is free of
charge since it is never really established. If the Travel SIM request was unsuccessful, you will not be
able to make calls from now on, since the AMCC cannot authenticate you. Such a failure should not
happen, unless your new SIM number was configured incorrectly on the AMCC.
What to do if Travel SIM doesn’t work
Your previously used SIM card will continue to work, unless there is a problem on
theAMCC-side: Check if there is a temporary problem by reinserting the former SIM card.
If it does not work, the error is likely to be located at the AMCC.
If repeated attempts to Activate SIM Cards fail and if the configured number of the second
SIM card is correct, the reason could be an improper Caller ID sent from your new SIM
card. In those cases the switch has to be conducted manually on the AMCC.
