The twin cities is 15x15 so it's possible they could be using sprints A block to widen to 15x15 in rush City. Duluth itself will be more complicated as the two combined don't have contiguous spectrum,vzw holds the 5x5 D block, so sprints was the 15x15 A block and TMO 15x15 B block in Duluth Sent from my SM-G975U1 using Tapatalk
