You can use a 3G/4G Router take a look at http://www.3gstore.c
With a router you can then connect up to 30+ devices via wifi, ethernet etc. As an example I have the MBR95 and it has 4 etherent ports, You would connect the MBR95 via wifi as a WAN and then all traffic would be directed through the MBR95.
