8.1.5 National Roaming – Preferred Network Operator
If the SIM card used supports "National Roaming", the modem usually first tries to connect to its
own mobile network. If there is no coverage (i.e. sufficient reception field strength) at the
measuring point, the modem books itself into a "foreign" mobile network, which is permitted by
the "National Roaming" option of the SIM card.
i
For information on which "foreign" mobile networks are supported for National
Roaming, please contact your mobile network operator / provider. Only he can tell you
bindingly which foreign networks he allows via "National Roaming".
If "National Roaming" is not to be used automatically, but a specific network operator is preferred,
the preferred network operator must first be entered and then the "Network provider selection"
mode must be specified.
8.1.5.1 Input „Preferred Network Operator"
To enter or change the information for the preferred network operator, navigate in the enSuite under
online" > "Parameters" > "Interfaces" >
"Parameterize
Name of the preferred operator "Oper.".
The entry itself can be made either by the plain text name of the network (e.g. "t-online.de") or by its
"Mobile Country & Network Code" (e.g. "26201"). If this parameter is deleted, the network provider selection
mode is selected automatically, regardless of whether another mode is selected.
i
The entry in plain text must exactly match the provider's name specified on the SIM
card. For example, "T-Mobile" is not identical to "telekom" or "T-D1". We therefore
recommend that you enter the unique Mobile Country & Network code.
i
Lists of the possible "Mobile Country & Network Code" can be found on the Internet at
https://www.mcc-mnc.com/, for example. However, the specifications of your mobile
phone provider whose SIM cards you are using are binding.

during selection.
