Note
Permanent storage of the SMSC number
If you configure an SMSC number, the CP no longer accesses the SMSC data of the
SIM card. This is also the case if you delete the SMSC number from the configuration
again.

service provider located on the SIM card. If you want to use it again later, you can
then use the SMSC of your provider again by configuring the SMSC number.
