YOUR AUDIO DESERVES MORE PLACES TO BE HEARD
STOP OVERLOOKING
CALLERTUNE.
10 ways CallerTune can support your content, message or brand.
01AUDIENCE-POWERED DISCOVERY
Let your audience carry your message.
When someone activates your CallerTune, people calling that number hear your audio while waiting for an answer.
02EVERYDAY MOBILE USE
Go where people already connect.
People use mobile phones to keep in touch every day. Put your audio into a familiar moment: the wait before someone answers.
03BEYOND SMARTPHONES
Your next listener may use a basic phone.
Callers don’t need a smartphone, an app or mobile data to hear your audio when calling an MTN subscriber who has activated it.
04NEW LISTENERS
Reach beyond your followers.
Your next listener could be a supporter’s friend, customer or colleague - someone your social posts never reached.
05YOUR STRONGEST HOOK
Let your best 30 seconds introduce you.
Give callers the chorus, voice or message you want them to remember. A short clip can introduce a song, a poem, an inspiring message or a business.
06VOICE & BRAND RECOGNITION
Give your sound a chance to stick.
A caller may hear your hook across several calls. Each listen is another opportunity to recognise your voice and remember your message.
07CONTENT PROMOTION
Put a campaign behind your content.
Every package includes a USSD discovery campaign. Potential reach: up to 5,000, 10,000 or 25,000 people, depending on your package.
08PERSONAL CONNECTION
Make your own number a starting point.
Once your audio is approved and available, activate it on your own eligible MTN line. Callers can hear your message before you answer.
09ANOTHER INCOME CHANNEL
Make room for another royalty stream.
Receive 50% of what NovaClarius receives for your content after operator and aggregator deductions. Earnings depend on subscriptions and settlement.
10OWNERSHIP & SETUP

Is CallerTune only for musicians?
No. We welcome preachers, poets, motivational speakers, businesses and other audio creators alongside musicians and labels. Submit audio you own or are authorised to distribute. All content is subject to rights verification and operator approval.
Can a business or organisation submit audio?
Yes. An authorised representative can submit a brand jingle or business message with the necessary rights documents. Contact us if you need guidance on submitting for an organisation.
Which network will carry my audio?
Our current offering is MTN Nigeria CallerTunez. The activation examples on this page are for MTN Nigeria subscribers.
What should I have ready?
Your audio, cover artwork, and documents showing that you own or are authorised to distribute the content. The upload form guides you through the rights documents required for your role. Have your royalty account details ready too.
Do I upload before or after payment?
After payment. You will receive a secure link for your content and rights submission. If you have already paid, recover your upload link rather than paying again.
Do I still own my content?
Yes. You retain ownership and authorise distribution under the CallerTune Distribution Agreement.
Does the package guarantee listeners or income?
No. The fee covers the services listed in your package. Listener uptake and earnings vary; campaign reach is a potential audience estimate.
