What is MTN Share and how does it work?
MTN Share — formerly known as Share ‘N’ Sell — is the feature that lets MTN prepaid and postpaid subscribers transfer part of their own airtime balance to another MTN number. It works via a simple USSD code or an SMS, it’s completely free of charge, and the airtime lands on the recipient’s line almost instantly. No app required, no internet connection needed — just your phone and your 4-digit transfer PIN.
It’s worth being clear about what MTN Share actually does: you’re moving airtime that already sits on your line to someone else’s MTN line. This is different from buying new airtime for another number — which you can also do, and which we cover at the end of this guide. Both options work in 2026; they just serve slightly different situations.
First things first: setting up your MTN transfer PIN
Before you can transfer airtime on MTN, you need a 4-digit transfer PIN. Without it, none of the methods below will work. Here’s everything you need to know about setting one up.
What is the default PIN for MTN Share?
The default PIN on every MTN line is 0000. You must change it before you can make your first transfer — MTN won’t let you use the default PIN for actual transactions. This is a one-time setup step and takes about 30 seconds.
How to create your MTN transfer PIN for the first time
You have two options. Via USSD: dial *321*0000*NewPIN*NewPIN# — replacing “NewPIN” with your chosen 4-digit code. For example, if you want your PIN to be 1234, dial *321*0000*1234*1234# and press the call button. Via SMS: send a message to 321 with the format 0000 NewPIN NewPIN — for example, 0000 1234 1234. Either way, you’ll receive a confirmation SMS from MTN once your PIN is set. Done — you’re ready to share.
How to transfer airtime on MTN using the USSD code
The USSD method is the fastest and most popular way to transfer airtime on MTN. No internet, no app — just dial and send.
What is the MTN airtime transfer USSD code?
The code is *321*RecipientNumber*Amount*PIN#. So if you want to send ₦500 to 08031234567 and your PIN is 1234, you dial: *321*08031234567*500*1234#. Press the call button and the transfer is processed in seconds.
Step-by-step guide to transfer airtime with the MTN USSD code
- Open your phone dialler and type *321*RecipientNumber*Amount*PIN#
- Replace RecipientNumber with the full 11-digit MTN number you want to send airtime to
- Replace Amount with how much airtime you want to transfer (minimum ₦50, maximum ₦10,000 per transaction)
- Replace PIN with your 4-digit transfer PIN
- Press the call button — not the SMS send button, the call button
- You’ll receive a confirmation SMS from MTN. The recipient gets their airtime almost instantly.
How to transfer airtime on MTN via SMS
If for any reason the USSD method isn’t working, the SMS route is a solid alternative. It’s slightly slower but just as straightforward.
How to format the SMS to transfer airtime
Send a text message to 321 with the following format: Transfer RecipientNumber Amount PIN. For example: Transfer 08031234567 500 1234. Use spaces between each element — no slashes, no commas, no colons. MTN will reply asking you to confirm the transfer — reply YES to 321 to complete it.
Step-by-step instructions for the SMS transfer
- Open your messaging app and create a new SMS
- In the To field, type 321
- In the message body, type: Transfer [RecipientNumber] [Amount] [PIN]
- Double-check the recipient number and amount before sending
- Hit send — MTN will reply asking you to confirm
- Reply YES to 321 to complete the transfer
PIN management: reset, change and troubleshooting
Can you transfer airtime on MTN without a PIN?
No. The PIN is mandatory for every MTN Share transfer and there’s no way around it — it’s there to protect your airtime balance from unauthorised transfers. If you haven’t set yours up yet, go back to the section above and do it now. It takes 30 seconds.
Forgot your PIN? Here’s how to reset your MTN transfer PIN
If you remember your current PIN but want to change it, dial *321*OldPIN*NewPIN*NewPIN#. If you’ve forgotten it completely, call MTN customer care on 180 (free from an MTN line) and request a PIN reset — you’ll need to verify your identity. You can also visit any MTN service centre with a valid ID.
How to change your existing MTN airtime transfer PIN
Dial *321*OldPIN*NewPIN*NewPIN#. Enter your current PIN where it says OldPIN, then type your new chosen 4-digit PIN twice. MTN will confirm the change by SMS straight away.
MTN airtime transfer limits, charges and key requirements
What are the limits for MTN airtime transfers?
According to MTN Nigeria’s official page, the minimum transfer per transaction is ₦50 and the maximum per transaction is ₦10,000. The daily cumulative cap is ₦100,000 — meaning you can make multiple transfers throughout the day as long as the total doesn’t exceed that figure. There is no limit to the number of individual transactions per day.
Is there a charge for transferring airtime on MTN?
MTN Nigeria states on its official website that MTN Share is free of charge — only the amount you transfer is deducted from your balance, with nothing added on top. Bear in mind you must have enough airtime on your line to cover the full transfer amount, and your account balance must be in positive (this applies to postpaid customers too).
Key requirements for transferring airtime on your MTN line
- ✅ Your MTN SIM must be registered and active
- ✅ You need a transfer PIN set up — the default 0000 must be changed before your first transfer
- ✅ You must have enough airtime on your line to cover the transfer amount
- ✅ The recipient must also be on the MTN network — transfers to other networks are not supported
- ✅ Yafun-Yafun and BetaTalk customers are excluded, as these are bonus-based plans
- ✅ Borrowed airtime (Xtratime) cannot be transferred — only purchased airtime
Can you transfer airtime from MTN to other networks?
No — MTN Share only works between MTN numbers. You cannot use it to send airtime to an Airtel, Glo, or 9mobile line. This is standard across all Nigerian networks: each operator runs its own closed transfer system. Airtel has its own Me2U service, Glo has its own transfer feature, and 9mobile has its own Share and Sell — but none of them cross over with MTN.
If you need to top up a number on a different network, the easiest option is a third-party recharge platform. doctorSIM lets you top up any Nigerian mobile network — MTN, Airtel, Glo or 9mobile — from anywhere in the world, without needing a local SIM or Nigerian bank account. And if you’re running low yourself and need someone to send you credit, the doctorSIM Request feature lets your family or friends top up your line in seconds — 100% online, no registration needed on their end either.
How to transfer airtime to money on MTN
This is a different feature from MTN Share, but it’s one of the most searched questions on the topic so it’s worth covering. Converting airtime to cash on MTN is possible through third-party platforms like Prestmit or Nosh, which buy your airtime at a set rate and pay you in cash to your bank account. MTN itself does not currently offer a direct native airtime-to-cash conversion via USSD — any code you’ve seen circulating online for this should be verified carefully before use, as many are outdated or inaccurate.
If you’ve received airtime you don’t need and want to convert it, your best bet is to check a reputable Nigerian fintech platform that offers airtime-to-cash services. Rates and availability vary, and the transaction is handled outside of MTN’s own systems.

And if it’s your own line that needs topping up, just share the doctorSIM Request link with someone abroad and they can send you credit in seconds, even if they’ve never used the platform before.
Bottom line: transferring airtime on MTN in 2026 is straightforward — dial *321*Number*Amount*PIN#, or text the same details to 321. Set your PIN once, keep it safe, and you’re sorted.
