In light of recent SIM disconnections due to the National Identification Number (NIN) – SIM harmonisation exercise, Nigerian telecom companies have released detailed instructions to help subscribers restore their service.

The harmonisation initiative, designed to enhance the integrity of the national SIM registration database, has caused temporary service disruptions for many users. To assist those affected, the following step-by-step guide outlines how to unblock your SIM card:

1. Airtel: Dial *121# and enter your eleven-digit NIN. A confirmation message will notify you that your Airtel SIM card has been successfully unbarred.
2. 9mobile (EMTS): Dial 2008# and follow the prompts.
3. Glo: Dial 109 followed by your NIN number (e.g., 10912345678901#) and follow the instructions to submit your NIN.
4. MTN: Visit nin.mtn.ng to check your NIN status. If not linked, proceed to link it. An OTP and NIN will be required. Once linked, your line will be automatically unbarred.
5. Smile: Send your NIN to customercare@smile.com.ng or call 07020444444. After providing consent and verifying your NIN, your line will be unbarred.
6. Spectranet: Call 8002345678 or email care@spectranet.com.ng to submit your NIN. KYC verification at a Spectranet store is required. You can also submit your NIN online but must complete KYC at a Spectranet store.
7. Ntel: Visit any Ntel store with your NIN. Your fingerprint will be used to verify your existing KYC profile. Upon verification and consent, your line will be updated and unbarred.
