The formula

MCC (mobile country code, 3 digits) and MNC (mobile network code, 2–3 digits) together identify a network — the same pair this site's import pipeline (README §3) uses to name operators. North American MCCs (3xx) use a 3-digit MNC; everywhere else uses 2 digits — e.g. 310-260 (T-Mobile US) vs 208-01 (Orange France).
