Inconsistent MCCMNC command

[Santiago De Renedo]

Hi all,

Not long ago I mentioned an issue I was having with setting the MCCMNC
using *--nas-set-system-selection-preference *where no matter what MCCMNC
was set, the modem would still connect to the sims network.

This seemed to be resolved at the time but I've been playing around with
that command and I believe that this problem actually occurs when also
using *--dms-set-operating-mode=reset *to reboot the modem. It takes about
a minute to lock back onto the sims network once the modem has been reset.

Here's the output of those commands including
*--nas-get-serving-system:*

I know this issue doesn't occur when setting the rate technology and I'm
wondering if this is a problem that is known about?

Thanks,

Santiago
