For the best performance and user experience with SmartSIM, please ensure that the Cellular Module is configured correctly for the use case

Step-by-step guide

Ensure the BG95 is configured for the desired cellular technologies and band combinations. These AT commands should ideally be performed by the IoT device host application:

  1. It is recommended to disable NBIoT support at this time: AT+QCFG="iotopmode",0

  2. If you don't require 2G support (and the module supports 2G), disable 2G to reduce scan times: AT+QCFG="nwscanmode",3

  3. An additional option to reduce scan times is to disable the bands that are not needed for your geographical region. The fewer bands the device has to scan the quicker it can connect
    ​

    1. i.e. for an EU only deployment, use the following command to only enable bands 20, 3, and 1 for M1 and 20, 8, and 3 for NBIoT: AT+QCFG="band",3, 80005, 80084

    2. Please refer to Quectel documentation for details around setting your geographical band combinations.

  4. Avoid using "manual detach" functionality using the AT+COPS=2 command. It is not implemented correctly.

    1. As a work-around, Airplane mode can be used: AT+CFUN=4
      ​
      ​

Following these guidelines will ensure the best connectivity experience.
