Note 1: +CPSMS
Note 2: +CEDRXS
Note 3: +URAT
Note 4: +UBANDMASK
If your carrier network is not on the supported list of MNOs, you must set to Cat M1 mode and follow the
instructions per that scenario below.
The MNG3 model has regulatory approval to operate in the EU/UK. We continue to work for approval on other
networks. Refer to the Sara-R4/N4 series AT Commands Manual for the list of supported MNOs and other details.
Note: If your device is on +UMNOPROF: 0 (SW default), you do not have a network defined yet and must
set one.
To set or switch carrier networks:
1. Deregister the module from the network or perform an AT+CFUN=0 cycle:
AT+CFUN=0
2. Set the carrier network (refer to the list of +UMNOPROF values):
To Vodafone:
AT+UMNOPROF=19
To Standard Europe:
AT+UMNOPROF=100
3. Reboot the module in order to apply the new configuration:
AT+CFUN=15
If the APN is known and will not change: We recommend hard-coding the MNO and setting the PDP context
manually. The following example of an AT command sequence is for Vodafone.
AT+CFUN=0
AT+UMNOPROF=19
AT+CGDCONT=1, "IPV4V6", "phone"
AT+CFUN=15
If the MNO is not listed: the following command sequence is recommended.
NOTE: We recommend changing +UMNOPROF separately before +UBANDMASK.
