From *1400# to *320#, here are all the 9mobile USSD codes you need in 2025—prepaid, postpaid and hybrid—plus fresh tariff rates, FAQs and top‑up tricks that guard your naira after the NCC‑approved 50 % hike.

When the Nigerian Communications Commission (NCC) authorised a 50 % increase in telecom tariffs on 20 January 2025 , every operator—including 9mobile—lifted call, SMS and data prices by the 31 March deadline.

With inflation still north of 30 % and the naira struggling, the old “set‑and‑forget” approach to voice plans can torch your budget. Luckily, 9mobile offers half‑a‑dozen packages—each with a unique USSD migration code—that can still slice your monthly spend if you pick wisely.

But here’s the kicker: many codes changed or were re‑mapped after the tariff hike as legacy bundles were retired. This guide compiles the latest, working USSD codes for every live 9mobile voice plan —prepaid, postpaid and hybrid—plus balance checks, opt‑out commands and real‑world savings tips.

Why Migration Codes Matter More After March 2025

• Higher baseline cost: Default prepaid calls on 9mobile now cost 42 k/sec (VAT incl.). Migrate to a discount plan or bleed naira.
• Auto‑migration triggers: Some plans (e.g., 9Konfam) push you back to default after bonus expiry (180 days). Knowing the right USSD prevents bill shock.
• Bonus ratios changed: 900 % and 1400 % headline numbers stayed, but underlying call/data splits shifted—USSD is your entry ticket to those perks.

Daily Access Charge: ₦7.50 (VAT excl.) hits your first call of the day—budget ₦8.06 VAT‑in.

Hybrid lines hold two wallets: a prepaid balance and a monthly credit limit.

Balance Check: *310# returns credit limit, usage and outstanding amount.

Frequently Asked Questions

Q1. Can I dial migration codes while roaming?
Yes, but you’ll be billed at roaming USSD rates (≈ ₦23/session); better to switch while on home network.

Q2. How do I confirm my current voice plan?
Dial *244*3# . The response SMS shows plan name and migration date.

Q3. Why does620 1# sometimes fail?
Insufficient balance for the ₦7.50 daily fee at point of migration triggers failure. Top up first.

Q4. Is there a universal opt‑out code?
*344*0# cancels most value‑added bundles; for tariff plans, you must migrate to another plan instead.

Q5. Can I combine Combopak with 9Konfam bonuses?
No—Combopak is SME‑tagged; you’ll be moved off 9Konfam upon purchase.
