Best 3g router

Hi Everyone.
i need to improve my upload speed.
i need to try and get 10mb up from combined 3/4G.
i am a photographer who shoots fashionshows in lots of countries.
there is always 3g and sometimes wifi.

theres never any time to set anything up.
the other problem is that if i plug dongles into the back they will get snapped off in minutes.
if i have three or 4 phones setup on hotspot with or without usb connections will the 30 router see them as wifi networks and combine them.

or do i need to look 2000 bucks for the peplink max.

what would be great is a router with 6 sim slots that works on battery, 12 volt preferably.

is there anything like that…

thanks
Sean

i am maybe being a bit dense

Our Pepwave MAX HD2 supports 2x SIM card and allows you to connect to a battery using the terminal block power input. You will also need to add another Peplink Balance device at your destination site.
