Cancellation service #1 in Nigeria
Callertunez is MTN Nigeria's caller‑tune service that plays a selected song or tone to callers instead of the standard ringing tone.
The service is subscription‑based and can be managed by the subscriber via USSD, SMS, app or the Callertunez website.
Once subscribed, recurring or single‑period charges appear on your MTN airtime or data balance depending on the plan.
Some users report unsolicited activations; if this happens you should cancel and keep evidence for a complaint.
When you unsubscribe, the selected tune stops being played to new callers from the point the system processes the cancellation.
The exact timing can vary; in many cases the tune stops immediately but some systems may apply the change after processing.
Cancellation prevents future automatic renewals and recurring deductions for the service.
There is no reliable indication that cancelling generates pro‑rata credits for the remainder of a billing period.
Available sources indicate MTN does not offer refunds once a charge is made for CallerTunez services.
Cancelling mid‑period does not usually result in pro‑rata credits or refunds. source
Below are the commonly listed Callertunez plans with reported Euro prices and approximate NGN equivalents.
Exchange rate used: 1 NGN ≈ €0.00060 (2025 average). Conversions are approximate.
| Plan | Price (EUR) | Approx. Price (NGN) | Period | Features |
|---|---|---|---|---|
| Single Tune (7 days) | €0.03 | ≈ ₦50 | 7 Days | Single tune, valid for 7 days |
| Single Tune (30 days) | €0.06 | ≈ ₦100 | 30 Days | Single tune, valid for 30 days |
| Bundled Tunez (7 days) | €0.06 | ≈ ₦100 | 7 Days | Bundle of tunes (multiple), valid for 7 days |
| Bundled Tunez (30 days) | €0.12 | ≈ ₦200 | 30 Days | Bundle of tunes (multiple), valid for 30 days |
In December 2024 the Nigerian Court of Appeal fined MTN N15 million for imposing unsolicited callertunes and messages after a subscriber had activated Do Not Disturb (DND).
The ruling reinforces that telecom providers must respect customer consent and privacy. source
The judgment cited protection of privacy under Section 37 of the Nigerian Constitution and Regulation 28 of the Consumer Code of Practice Regulations.
These laws and regulations support complaints where services were applied without proper consent. source
Many user reports on forums say CallerTunez has been activated without clear consent, causing unwanted airtime deductions.
Longstanding threads describe recurring charges and characterise the service as problematic. source source
There are no widely available verified positive review aggregations for Callertunez on major review sites specific to Nigeria.
Some subscribers use and enjoy caller tunes, but public commentary is dominated by concerns about unsolicited activations.
Sending the wrong SMS keyword or dialing the incorrect USSD code can leave the subscription active.
Always double‑check the code before sending and save confirmation of the unsubscribe attempt.
Many users expect a refund when cancelling mid‑period; MTN typically does not provide pro‑rata refunds.
If you believe you were charged without consent, collect evidence and escalate rather than assuming automatic reimbursement.
The table below compares cancellation options by ease, speed and requirements to help you choose a method.
| Method | How to use | Speed | Internet required | Notes |

Check your airtime balance and itemised billing for at least two billing cycles after cancellation to ensure no further deductions occur.
Keep unsubscribe confirmations and SMS delivery receipts as proof in case of dispute.
