Limit mobile module to a specific FREQ or cell

This feature limits the mobile module to a specific FREQ or cell. The following information is required to execute this:

1. Enter the Type, Name, and AT commands shown in the table below to read current mobile info.

   Type	Name	AT command	Show Lines
   user-defined	nwscanmode	AT+QCFG=[nwscanmode]	2
   user-defined	serving_cell	AT+QENG=[servingcell]	2
   user-defined	lock_the_cell	AT+QNWLOCK=[common/lte]	2

2. The read command output table displays the newly added read commands as shown below:
   
   

3.  In the Query Command, set the Type to Advanced send command and enter AT+QCFG=[nwscanmode],3 in the AT command to Send.
   
   

   This should be done before locking the LTE cell.

4. To lock the mobile module to a specified FREQ or cell, in the Query Command, set the Type to Advanced send command, and enter AT+QNWLOCK= [common/lte],2,<EARFCN>,<PCI> in the AT command to Send.
   
   

   This approach locks the mobile interface only up to one cell. Insert the SIM card before the locking cell procedure.

5. Verify whether the "nwscanmode" and "lock the cell" are changed in the Read Commands Output table.
