Transfer Airtime on MTN: *321# Code, 0000 PIN and ₦10,000 Limit
Dial *321*number*amount*PIN# to send MTN airtime, after you change the default 0000 PIN. USSD and SMS steps, the ₦10,000 limit, and what to do if it fails.

To transfer airtime on MTN, dial *321*recipient's number*amount*PIN# from your own MTN line. First change the default 0000 PIN, because MTN refuses every transfer until you do.
Below you'll find the USSD route, the SMS route, how to change the PIN, MTN's limits as at 30 September 2026, and what to check when a transfer fails.
How to transfer airtime on MTN with the USSD code
MTN calls this service MTN Share. Some people still call it Share 'N' Sell, which was its old name.
These steps assume you've already changed your PIN. If you haven't, do the PIN section below first and come back here after.
- Dial
*310#to check your airtime balance. - Dial the transfer code with the receiver's full MTN number, the amount in whole naira and your PIN:
*321*0803XXXXXXX*1500*1234# - Press the call button.
- Dial
*310#again to confirm the airtime has left your line.
Swap 0803XXXXXXX for the real number and 1234 for your own PIN. Type all 11 digits with no spaces. The amount goes in as whole naira, which means no kobo, no commas and no ₦ sign, and your four-digit PIN sits right at the end, just before the #.
MTN charges no fee. Only the amount you send leaves your balance.
How to send MTN airtime by SMS
The SMS method does the same job. Use it when the USSD code keeps timing out on you.
On the MTN line that holds the airtime, type the word Transfer, then the receiver's number, the amount and your PIN, with a space between each part: Transfer 0803XXXXXXX 1500 1234. Send that message to 321.
MTN then texts back asking you to confirm, and you reply YES. Skip that reply and nothing gets sent, even though your first message went through, so keep the messages app open for a minute while the confirmation arrives.
Dual-SIM phones catch people out here. Check which SIM the text is leaving from, because it has to go out from the MTN line with the airtime on it, not your other SIM.
How to change your MTN transfer PIN from 0000
Every MTN line starts with the transfer PIN 0000. MTN's page says you must change it before you can transfer airtime on MTN. A new PIN also stops anyone who picks up your phone from sending your credit away.
- Choose four digits you will remember. This example uses 4821.
- From the line you want to protect, dial the old PIN, then the new PIN twice:
*321*0000*4821*4821# - Press the call button.
By SMS, text the old PIN followed by the new PIN twice, with spaces (0000 4821 4821), to 321. From then on, your new PIN goes at the end of every transfer code.

Avoid 1234 and your birth year. Those are the first numbers anyone would try.
MTN Share limits: ₦50 minimum, ₦10,000 per transfer, ₦100,000 a day
Here are MTN's airtime transfer limits as at 30 September 2026, taken from its own Share page.
| Rule | What MTN allows |
|---|---|
| Minimum per transfer | ₦50 |
| Maximum per transfer | ₦10,000 |
| Daily limit | ₦100,000 in total, across everyone you send to |
| Fee | None |
| Who cannot use it | Yafun-Yafun and BetaTalk prepaid plans, and postpaid accounts that are not in positive |
Sending one person more than ₦10,000 means splitting it into several transfers. Every transfer you make that day, whether to that person or to anyone else, adds to the ₦100,000 daily total, and once you reach it you have to wait until the next day.
Say you need to send ₦15,000 to one person. Make two transfers: ₦10,000 first, then ₦5,000. Both count towards today's total.
MTN airtime transfer failed? Check these 8 things
Start with the PIN, because that's where most transfers go wrong. Either the line still has 0000, or you changed it and then typed 0000 anyway out of habit.
Next, look at the amount. It must sit between ₦50 and ₦10,000, your balance has to cover it, and you can't have used up today's ₦100,000 total already. Then read the receiver's number again, digit by digit, and make sure it's on MTN.
By SMS, confirm you really replied YES. Last of all, lines on Yafun-Yafun or BetaTalk can't use MTN Share, and a postpaid account has to be in positive.
Dial *310# before you try again. If your balance has dropped, the airtime has already left your line, so ask the receiver to check their balance before you send the same amount twice.
MTN's Share page lists no way to reverse a transfer. Send to a wrong number and only that person can send it back.
The balance code and many more are on our list of other MTN USSD codes.
Can you send MTN airtime to Airtel, Glo or T2?
No. MTN Share only moves airtime from one MTN number to another MTN number, so *321# can't send credit to an Airtel, Glo or T2 line. It won't pull Airtel airtime onto an MTN line either.
Buy the airtime straight onto the other person's number instead. It lands on their line, and nobody has to set up or remember a transfer PIN.
