(although I never saw many problems before with this).
I would still appreciate it if others could test and

working well (but will require firmware support
later). The ‘final’ list of hardware changes are as

certification will take 6 to 8 weeks and be complete
around the end of November. Once that is done, we
should be able to go to full production in time for
Christmas. Pricing will be confirmed early December,
but likely more expensive than v3.2 due to the extra
cost for SIM7600G and certification fees.</div>
