Powershell - Get computers IMEI, and SIM card number ~ Remote PC

I just went through a marathon session, setting up several Dell 7212 Rugged tablets, that came with their SIM card already inserted...

In order to activate the cellular capabilities with a carrier, the following two details are required...
     But these are kind of a hassle to get to. And to work with...

•      The IMEI number (device ID)
•      The SIM card number

I found it MUCH easier to get to this info from my own computer, than from the tablet, as follows:
   ~ Note - About the Test-WSMan, PsExec, and the winrm config...
    ~ These just make sure WinRM is enabled. 
     ~ 'Invoke-Command' requires WinRM

$Target = "HOSTNAME"

$TestCommand = $null
$TestCommand = Test-WSMan -ComputerName $Target
If (!($TestCommand)){C:\SysInternals\PsExec.exe -s -nobanner \\$Target /accepteula cmd /c "c:\windows\system32\winrm.cmd quickconfig -quiet"}

$Network_IMEI = Invoke-Command -ComputerName $Target -ScriptBlock { netsh mbn show interfaces }
$Network_SIM = Invoke-Command -ComputerName $Target -ScriptBlock { netsh mbn show read interface=* }
$IMEI = ((($Network_IMEI | select-string "device id").ToString()).Trim()).replace('              ','')
$SIM = ((($Network_SIM | select-string "SIM ICC Id").ToString()).Trim()).replace('       ','')
Write-Host "Cellular device info:" -ForegroundColor Cyan -BackgroundColor DarkGreen
$IMEI
$SIM

There's plenty of extra lines in there, to make it look pretty, but you should get the point, pretty easily.
The two pieces (from what I could see), are in different parts of the mnb. So... Two commands.

It took me a while to figure this all out... To get BOTH the IMEI number, and the SIM card number.

Hope it helps someone else!
