SIM Swap Procedure on LNA7 mPower 5.2

PROBLEM: When changing the MTR-LNA7 from one SIM card to another, cellular connection can be lost.

Switching SIM from AT&T to Verizon:
-----------------------------------
Step 1: Remove the AT&T SIM
Step 2: Insert the Verizon SIM
Step 3: Factory Default either using the UI ( Administration -> Save/Restore -> Reset to Factory Default Configuration) or press and hold the reset button for 30+ seconds. 

Steps you can try without factory default:
Step 1: Clear carrier settings. 
        For WWAN -> Remove APN. 
        For PPP -> Remove APN and change dial string to *99***3#. 
        After changing hit Save & Apply
Step 2: Pop the SIM out. 
Step 3: Go to Administration -> Debug options  -> Radio Terminal -> Show and type AT+QMBNCFG="Deactivate". Wait for "OK" response. ( Try again if you don't receive "OK" response)
Step 4: Unplug Power. 
Step 5: Pop the SIM in and power up. 


Switching SIM from AT&T to Verizon and then back to AT&T:
---------------------------------------------------------
Step 1: Remove the AT&T SIM
Step 2: Insert the Verizon SIM
Step 3: Factory Default either using the UI ( Administration -> Save/Restore -> Reset to Factory Default Configuration) or press and hold the reset button for 30+ seconds. 

Switching SIM from Verizon (APN1) to another Verizon SIM with a different APN (APN2) :
-------------------------------------------------------------------------------------------------------------------------
Step 1: Remove the APN1 Verizon SIM
Step 2: Insert the APN2 Verizon SIM
Step 3: Enable ssh ( Administration -> Access Configuration -> SSH settings ) 
Step 4: Using a Terminal tool like Putty ssh into the device and login with username and password that you used to login to the UI. 
Step 5: Elevate your privileges to root by running "sudo -s". ( password is the same as the admin password that you used to login to the UI). 
Step 6: Use the microcom tool to run AT commands on the device. 
        a. microcom /dev/modem_at1
        b. Type "ate1" and hit enter/return ( This is to enable echo of commands you type. when you type this you might not see this being typed on the terminal program)
        c. Type at+qodm="dme",2,"ui" ( You should see the output +QODM: "DME",0,DM Start  +QODM: "DME",0,DM End )
        e. CTRL+X to exit. 
        f. Type radio-cmd at+cgdcont? to verify your correct APN received by Over The Air(OTA) process by Verizon. ( You will be mainly focusing on +CGDCONT: 3 value)
Step 7: If you had SSh disabled previously go back to  Administration -> Access Configuration -> SSH settings and disable SSH to revert your SSH settings. 
Step 8: Restart device ( Commands -> Restart device ) After restart verify that you have a cellular connection. 


For all three scenarios once you have a cell connection you don't have to repeat this process if you are not swapping SIMs.
