inserted into a mobile phone. Now the card can be unblocked according to the details of the network
providers.
5.5.1 Device types
Depending on the device type, the correct type has to be selected. The selection has an influence on the
configuration of the inputs and outputs. It is however possible to correct the selected type at any time.
5.5.2 Automatic provider search
The automatic provider selection depends on the SIM card inserted into the SMS Relay. The provider details
and access of the SIM card are adapted. Basically, the provider is preassigned when the SIM card is
purchased. With the “Automatic” setting, the network provider is automatically searched and logged. That is
useful if the card is used in the home network. Other GSM networks can be accessed abroad with the same
SIM card according to the roaming contracts.
5.5.3 Manual provider search
For manual provider searches, the available GSM networks are scanned several times. The results of this
search are displayed with a list of networks. A mouse click on “Search“, and then the available networks
would be shown. The desired network can now be chosen. The SMS service centre number can be taken from
the SIM card documentation. Normally this number is already saved on the SIM card. The number depends
on the GSM provider.
