Why 9mobile USSD Codes Matter

9mobile (formerly Etisalat Nigeria) has carved out its space in Nigeria’s telecom industry with innovative offers, clear tariffs, and strong focus on customer care. Although it has fewer subscribers compared to MTN, Airtel, and Glo, 9mobile remains popular, especially in urban areas, among younger users, and in niches like data-heavy plans and international call bundles.

For these customers, USSD codes remain a vital access point. USSD works without internet, on both feature phones and smartphones, and even in low-signal areas. In a country where not everyone has constant internet, USSD is the equalizer—ensuring subscribers can recharge, check balances, buy data, or borrow airtime instantly.

In 2023, the Nigerian Communications Commission (NCC) harmonized major codes across all networks, including 9mobile. That means the codes you learn here are the same you’ll use on MTN, Airtel, or Glo for key actions like:

  • Balance check: *310#

  • Recharge: *311*PIN#

  • Data menu: *312#

  • Borrow services: *303#

  • Data balance: *323#

  • Share services: *321#

  • VAS STOP menu: *305#

  • Help desk: *300#

  • NIN/SIM services: *996#

This uniform system helps subscribers with multiple SIMs and makes it easier to remember codes.

Key takeaways

  • Recharge: *311*PIN#.
  • Check airtime balance: *310#.
  • Buy/manage data: *312#.

How to Recharge on 9mobile (and Confirm It Worked)

Recharging is the most basic action every 9mobile subscriber must know. Even though there are online and app-based methods, USSD recharge with a physical card remains the most reliable—no internet, no app login, just a simple dial.

Steps to recharge your line:

  1. Buy a 9mobile recharge card from an authorized vendor.

  2. Scratch gently to reveal the 15-digit PIN.

  3. Dial *311*PIN# and press the call/send button.

  4. You’ll instantly receive an on-screen confirmation.

  5. An SMS will follow, confirming the amount credited.

To check your updated balance: Dial *310#.

Troubleshooting recharge issues

  • Invalid PIN error: Usually caused by a typing mistake. Re-enter carefully.

  • PIN already used: If you get this message, keep the recharge card and call customer care on *300. Provide the serial number for investigation.

  • Recharge deducted but not credited: Wait 1–2 minutes and dial *310#. If it still doesn’t reflect, contact support immediately.

  • Weak signal: If you’re in an area with poor network, move to a better coverage spot before retrying.

Real-life example

A businesswoman in Lagos recharged ₦1,000 but didn’t see it reflect. After calling *300 and providing the recharge card’s serial number, the issue was resolved, and her line was credited within 24 hours.

How to Check Airtime Balance on 9mobile

The universal balance check code is *310#. This shows your remaining airtime instantly.

Why checking balance matters

  • Prevents unexpected call disconnections.

  • Ensures you know when to recharge.

  • Determines eligibility for borrowing services.

Tip: Always check your balance before borrowing, sharing, or buying data.

Troubleshooting

  • Code not responding: Restart your phone or toggle Airplane Mode.

  • Balance not updating after recharge: Wait a few minutes; if it still doesn’t refresh, contact customer care.

How to Buy, Manage, and Cancel 9mobile Data Bundles

9mobile is known for data-driven offers—from night plans to social bundles. You can access all of them via *312#.

Steps to buy data

  1. Dial *312#.

  2. Select from categories like daily, weekly, monthly, mega, or social plans.

  3. Confirm your choice.

  4. You’ll get a confirmation SMS with the details of your bundle.

How to cancel auto-renewal

Many 9mobile bundles auto-renew by default. To stop this:

  • Dial *312# → choose “Manage Data” → select “Cancel Auto-renew.”

  • Or reply to the SMS confirmation with the stop code (usually “STOP” or “NO”).

Common issues with data

  • Airtime deducted without bundle activation: This happens if PAYG browsing is active. Always dial *312# before turning on mobile data.

  • Bundle not activated: Ensure you have enough airtime for the plan plus VAT. If deducted but not credited, contact support.

  • Bundle expires early: Most plans have strict validity periods. Always check expiry dates.

Real-life example

A student in Abuja subscribed to a ₦500 daily plan but got no data. After reporting with his session ID (from the SMS), the issue was resolved, and his bundle was reissued within 48 hours.

How to Check Data Balance on 9mobile

To monitor usage: dial *323#.

This shows:

  • Remaining data (in MB/GB).

  • Validity period.

  • Active bonuses (if available).

Alternative checks:

  • SMS: Some plans let you text “INFO” to 323.

  • My 9mobile app: Provides detailed usage reports if you’re online.
