Follow this procedure to properly set up the configuration:
• Deregister the module from the network (perform a AT+CFUN=0 or AT+CFUN=4 cycle or issue the AT
+COPS=2 command)
• Issue AT+UMNOPROF=<MNO>
• To apply the new configuration reboot the module
o SARA-R4 / SARA-N4 - by means of the AT+CFUN=15 AT command. If <MNO>=1 (SIM ICCID select),
reboot the module twice to apply the MNO profile configuration.
After setting a new configuration the module reconfigures the PDP context settings (e.g. APN of the initial EPS
bearer).
SARA-R410M-02B / SARA-R410M-52B / SARA-R412M
On SARA-R410M-02B-00, SARA-R410M-52B-00, SARA-R412M-02B-00 and SARA-R412M-02B-01 if
<MNO>=1 (SIM ICCID select), it is not necessary to reboot the module the second time. Immediately after
issuing the AT+CFUN=15 command the proper MNO profile configuration is applied.
SARA-R4 / SARA-N4
Changing the Mobile Network Operator (MNO) profile with the +UMNOPROF AT command overwrites
some AT command settings and applies the default MNO profile values. For the list of AT commands
affected by +UMNOPROF AT command, see Mobile Network Operator profiles.
Follow this procedure to restore the profile factory-programmed configuration:
• SARA-R410M / SARA-R412M / SARA-N4 - Set a different profile than the current one and then set the the
profile back to the original. Reboot the module (AT+CFUN=15) to make the change effective.
SARA-R4 / SARA-N4
The version of the MNO profiles can be displayed by issuing the set command AT+UMNOPROF=,1 and
then the test command. The MNO profile version will be displayed after each profile in the list.
u-blox cellular modules are certified according to all the capabilities and options stated in the Protocol
Implementation Conformance Statement document (PICS) of the module. The PICS, according to 3GPP TS
51.010-2 [65], 3GPP TS 34.121-2 [66], 3GPP TS 36.521-2 [93] and 3GPP TS 36.523-2 [94], is a statement of the
implemented and supported capabilities and options of a device. If the user changes the command settings
during the certification process, the PICS of the application device integrating a u-blox cellular module must
be changed accordingly.
7.16.1.1SIM ICCID selection
If the <MNO> parameter is set to 1 (SIM ICCID select), the mobile network operator profile is selected according
to the recognized SIM Issuer Identifier Number (IIN). For more details on the recognized SIM IINs ranges, see
the SARA-R4 application development guide [177].
SARA-R410M-63B / SARA-R410M-73B
If a SoftBank or a NTT DoCoMo SIM is inserted the mobile network operator profile (<MNO>) is
automatically set according to the SIM. After that if the mobile network operator profile (<MNO>) is
modified to not match the SIM, the MT is set to minimum functionality (+CFUN: 0); it is not possible
to restore the MT to full functionality (+CFUN: 1), until the mobile network operator profile is not set
according to the SIM.
