The set command sets country-specific data. The command configuration is
stored to Non-volatile Memory (NVM) approximately every 48 hours and when the modem is
powered off with the +CFUN=0
command.
Syntax:
%XCOUNTRYDATA= <oper>,[<country_1>][,country_2>]…|,country_70]
where <country_x> contains <act>,<mcc>,<band>,<earfcn>[,band_2,earfcn_2]..[,band_5,earfcn_5].
The set command parameters and their defined values are the following:
The following command example writes two country elements. In the first country element, <act> is LTE-M, <mcc> is 244, <band> is 3, and <earfcn> is 1207. In the second country element, <act> is Narrowband Internet of Things (NB-IoT), <mcc> is 212, <band> is 20, and <earfcn> is 6150, <band> is 13, without specific <earfcn>:
AT%XCOUNTRYDATA=1,”4,244,3,1207”, “5,242,20,6175,13,0”
OK
The following command example deletes existing country data from the modem:
AT%XCOUNTRYDATA=0
OK
