Colorado-specific considerations
Skiing, 14ers, and backcountry have limited service — Verizon reaches furthest; download offline maps and don't rely on signal.
I-70 through the Rockies and the high passes drop signal — plan for gaps on mountain drives.
High-country weather makes coverage a safety issue on remote roads — carry the widest network (Verizon).
Denver's dense corridors and events congest — a high premium-data cap helps.
