Hi,

As for the models, we sell them as OEM. You may contact me offlist if
interested. Better priced and more powerful than existing devises out there.

Quescomm, are good but have drawback. 12 SIMs model you need to unscrew to
change the SIMs. This is not very practical. I recommand other brands like
Vierling, who are more practical in everyday life of a corporate grade carrier
devise.

The idea is brilliant. I haven't seen such product on market. Tellular have
something similar, but you still need some workout. I have other solution for
this functionality: In europe you can have two SIMs for same phone number. In
Belgium for instance (proxi-Duo).

Then, you plug one SIM in the GSM Gateway and another one in the GSM devise.
When you get home you switch your GSM and automatically the other sIM becomes
active, when you walk away you switch your GSM phone on and it will
automatically become active.

Some GSM network operators do this. Last SIM registered is one to be considered
and others become inactive.

Hmm. What is added value of customers using their cell phone in callshops? They
have walked all the way long to reach the place. You may explain further
