Which modem to use with a sim.

Hi all. So we have moved into our new home only to find that Telcom's ADSL doesn't work as we are to far from the exchange.

So we now have to use a cell based network.
After some research I came across 153 Mobile who have a pretty good deal going for 100 gigs which suits our needs. Any one here using them?
I'm looking for a router that I can simply install the sim card and set it up as per normal.
Those small portable 3g routers aside.

Thanks in advance.
