T Mobile US (TMUS) Customers by Type

Splits the customer base into postpaid, prepaid, wholesale, and IoT segments to show where growth and profitability originate. A rising share of postpaid and IoT customers tends to boost stable, higher‑margin revenue, while growing prepaid volume can lift subscriber counts but pressure ARPU and margins.

The abrupt fall in reported postpaid customers around 2025 looks like a reporting/reclassification change (accounts vs. lines), not a business collapse: management is simultaneously raising guidance for ~1M postpaid net account additions, ARPA, service revenue and EBITDA. Takeaway for investors is to prioritize account-level additions, ARPA and broadband traction (0.5M+ broadband adds) over raw headcount; also watch elevated account churn and widening equipment losses, which could erode the improved revenue per account trajectory if persistent.
