Fwd: Re: 4G on Dell IoT Gateway

[Oriol Rius]

Hi Carlo, thanks for your feedback playing about that with Alfonso. We 
found problems detecting SIM with that modem. The strange thing is that 
SIM cards that I tested are working on other devices and connected with 
Dell both of them fail. The error is always 'sim-missing'.

I don't know how to solve that and I don't have feedback from Dell.

Regards.

Oriol
