• AT&T's EF
RAT
mode contains the RAT mode setting, the RAT mode setting is the mode that the module
shall be set to. Thus this setting may override +URAT's <SelectedAcT> and <PreferredAct> loaded at
boot time.
SARA-R404M / SARA-R410M-01B
• <SelectedAcT>=0, 1, 2, 4, 5, 6, 7, 8, 9 are not supported. The factory-programmed value of <SelectedAcT>
is 3.
SARA-R410M-02B / SARA-R410M-52B
• <SelectedAcT> is the first AcT the module will search. In the case a suitable cell can't be found on this
AcT, the module will search the <PreferredAct> if defined.
• <PreferredAct> is the next AcT the module will search if no suitable cell can be found on the
<SelectedAcT>. In the case a suitable cell can't be found on this AcT, the module will search the
<2ndPreferredAct> if defined.
• <SelectedAcT>=0, 1, 2, 3, 4, 5, 6, 9 are not supported. The factory-programmed value of <SelectedAcT>
is 7.
• <PreferredAct>=0, 2, 3, 9 are not supported. The factory-programmed value of <PreferredAct> is 8.
• <2ndPreferredAct>=0, 2, 3, 9 are not supported. The factory-programmed value of <PreferredAct> is

Configures the network registration information. Depending on the <n> parameter value, a URC can be issued:
• +CREG: <stat> if <n>=1 and there is a change in the MT's circuit switched mode network registration status
in GERAN/UTRAN/E-UTRAN
• +CREG: <stat>[,<lac>,<ci>[,<AcTStatus>]] if <n>=2 and there is a change of the network cell in GERAN/
UTRAN/E-UTRAN
