Yes, that's why there is a 3G module in there 
I have not yet tested it myself, the NAT your telco will do should not be a problem as my Kerlinks work fine behind residential and office NAT. However, as your telco most likely will assign a private space IP address, there is no way for you to ssh into the box without special measures. Others on the forum already have asked wether the box is capable of setting up an VPN. It should be possible, but not out of the box.
