In Nigeria, airtime sharing is more than just a mobile feature, it's a lifeline. From helping family members stay connected during emergencies, to quickly bailing out a friend who's run out of data mid-Instagram reels or acebook chats, we've all had those moments where every second counts. That's where MTN's share and sell service comes in to save the day.

In this guide, you'll learn exactly how to share airtime on MTN step-by-step without any stress or guesswork. We'll walk you through all the updated airtime sharing methods available in 2025:

• The updated USSD code that works on any phone (even that small torchlight Nokia in your drawer)
• The SMS method for those who prefer typing over dialing
• The MyMTN App option for real-time transfers with a few taps

Plus, we'll share pro tips to avoid failed transactions, PIN issues, and network wahala. So, let's get you started on how to send airtime like a pro.

What Is MTN Share & Sell?

MTN Share & Sell is MTN's official airtime transfer service that lets you send airtime from your own MTN line to another MTN line instantly. Whether it's for family, friends, or that colleague who "just needs a small recharge to make one quick call," this service is your go-to way to share value.

Key Things You Need to Know:

• MTN to MTN only - You can't transfer airtime to Glo, Airtel, or 9mobile lines
• Works for both prepaid and postpaid MTN customers
• Requires a Transfer PIN for security reasons (The default pin for transfer is 0000, but you should change it ASAP)
• All transfers are final: Once sent, you can't reverse it
• Limits apply: There's a maximum amount you can send per transaction and per day

If you've got your PIN ready and your balance is loaded, you're good to go.

How to Share Airtime on MTN Using USSD Code

IMPORTANT UPDATE: MTN has changed their airtime sharing code in 2025. The old *777# code no longer works. The new official code is *321#.

Method 1: Direct Dial (Quick Transfer)

New 2025 Code:

*321*RecipientNumber*Amount*PIN#

Example:

*321*08030000000*100*1234#

You'll get an instant confirmation message.

Your recipient should receive the airtime immediately the confirmation message comes in.

Tip: If you're still using the default PIN 0000, change it first (see our PIN section below).

Method 2: Menu Navigation (Step-by-Step Prompts)

Dial *321# on your MTN line

Select Airtime Share & Sell from the menu

Enter the recipient's number, amount, and PIN when prompted

Wait for the confirmation SMS

Why Use USSD?

• Works on any phone ; from smartphones to old-school torchlight phones
• No internet required
• Quick and straightforward

Troubleshooting USSD Transfers

• "Invalid PIN": This means you need to reset your PIN before trying again
• "Transfer failed": Check if you have enough airtime and if the MTN network is stable from the network bar at the top of your phone

How to Share Airtime on MTN via SMS

If you prefer typing over using USSD codes, MTN's SMS method for airtime transfer is just as effective. All you need is your phone's messaging app and no internet is required for this.

How It Works

Open your phone's SMS app

Type your message in this format: Transfer RecipientNumber Amount PIN

Example:

Transfer 08030000000 100 1234

Send the SMS to 777

• Simple and easy to remember, just type: "Transfer, number, amount, PIN"

Tips for SMS Transfers

Common Issues & How to Fix Them

Even though MTN Share & Sell is straightforward, a few challenges can happen along the way. Here is how to quickly solve them so you don't get stuck.

1. "Invalid PIN" Error

Cause: You entered the wrong Transfer PIN, or you haven't changed the default PIN yet.

Fix:

• Double check your PIN entry and it must be exactly 4 digits
• If you're still using the default PIN (0000), change it first using: *600*0000*NewPIN*NewPIN#
• If you've forgotten your PIN, see Section 6 for reset methods.

2. "Transfer Failed" Message

Cause: Your airtime balance is too low or there's a temporary network problem.

Fix:

• Check your airtime balance by dialing *310# (updated 2025 code)
• Make sure you have enough balance plus the minimum leftover airtime required by MTN
• Try again when you have stronger network signal

3. "Recipient Not MTN"

Cause: You're trying to send airtime to a number on another network (Airtel, Glo, 9mobile).

Fix:

• MTN Share & Sell works only MTN-to-MTN
• Confirm the recipient's number really belongs to MTN before retrying

4. Network Delay (No Confirmation SMS)

Cause: Temporary congestion in MTN's system.

Fix:

• Wait a few minutes as the transaction might still go through
• Check your balance to see if the airtime was deducted
• If you still haven't received confirmation after 30 minutes, contact MTN Customer Care by dialing 300 or visiting the nearest MTN service centre

Pro Tip: Always double-check the recipient's number before pressing send. Transfers are instant and irreversible, once airtime lands in the wrong account, only the recipient can send it back.
