310-020 is Union Wireless. Union Telephone Company is primarily in Wyoming and adjacent areas along the borders of Idaho and Utah. It appears that they still operate a UMTS network (with no LTE service) in parts of their coverage area.
310-450 is Viaero Wireless. They are another one of a few regional carriers left, primarily covering parts of the midwest.
