The State Of Postpaid In Nigeria (2025 Snapshot)

9mobile doesn’t lead on raw local tariff, but it beats rivals on credit duration and VIP call management—two levers that matter more than ever amid soaring interest rates.

Perk #1 — VIP Caller Lists & Custom Whitelisting

• What It Is: Classic Postpaid lets you create up to 50 VIP numbers whose calls always ring through—even in Do‑Not‑Disturb hours—or block entire ranges (blacklist).
• Why It Matters: Reduces spam, prioritises CXO calls and eliminates missed‑deal anxiety.
• 2025 Upgrade: Web portal now supports real‑time edits ; no account‑manager ticket needed.

Dual‑SIM Tactic: Keep Classic Postpaid in SIM 1 and a prepaid data SIM in SIM 2. Allow VIP numbers to route to SIM 1; all other calls can ring SIM 2 where cheaper plans or call‑filter apps manage noise.
