The good news is that sharing data on 9mobile is quick once you know the correct steps.
In this guide, you’ll learn how to transfer data on 9mobile, how to change your transfer PIN, common reasons data transfers fail, and the easiest way to top up your data whenever you need more.
Can You Share Data on 9mobile?
Yes.
9mobile allows eligible subscribers to transfer part of their active data bundle to another 9mobile user. The network also offers Data Gifting, which lets you purchase a brand-new data bundle for someone else instead of transferring from your existing balance.
This makes the service useful for:
- Helping family and friends stay connected.
- Sharing data between your own 9mobile SIM cards.
- Sending emergency data.
- Supporting students or remote workers who suddenly run out of internet.
Remember that data transfers only work between 9mobile numbers. You can’t send data to MTN, Airtel, or Glo subscribers.
9mobile Data Transfer vs Data Gifting
Many subscribers think they’re the same thing, but they aren’t.
Data Transfer
This allows you to send part of your existing data bundle to another 9mobile customer.
Your own remaining data balance reduces by the amount you transfer.
Data Gifting
Instead of using your own data, you purchase a completely new bundle for another 9mobile subscriber using your airtime.
Their bundle has its own validity period and doesn’t affect your current subscription.
What You’ll Need Before Sharing Data
Before starting the transfer, make sure you have:
- An active 9mobile SIM.
- An eligible data bundle.
- Enough remaining data.
- The recipient’s correct 9mobile phone number.
- Your data transfer PIN.
If you’re transferring data for the first time, you’ll usually need to change the default transfer PIN before the transaction can be completed.
How to Share Data on 9mobile (T2mobile) Using USSD
9mobile (now operating as T2mobile) allows you to transfer data from your existing data balance to another 9mobile/T2mobile number.
Method 1: Direct USSD Code (Fastest)
- Dial: *229*YourPIN*DataAmount*RecipientNumber# Example: To send 500MB to 08091234567 with PIN 1234 → *229*1234*500*08091234567#
- Press the call/send button.
- Confirm the transaction when prompted.
- Both you and the recipient will receive a confirmation SMS if successful.
Method 2: USSD Menu
- Dial *312*7# (or *321*2# / *301# on some lines) and follow the prompts.
- Select the Data Transfer / Share Data option.
- Enter your transfer PIN.
- Enter the amount of data you want to send (in MB).
- Enter the recipient’s 9mobile number.
- Confirm the transaction.
Important Limits (as currently applied):
- Maximum 200MB per transfer
- Maximum 1GB per day
Notes:
- You can only transfer to another 9mobile/T2mobile number.
- The data must be from an eligible (transferable) bundle — some promotional or bonus data may not be transferable.
- Nigerian networks occasionally update their USSD menus, so if the options look different, just follow the latest prompts on your phone.
How to Change Your 9mobile Data Transfer PIN
Your transfer PIN protects your data from unauthorized transfers. The default PIN is usually 0000. You should change it immediately.
To change your PIN:
- Dial: *247*CurrentPIN*NewPIN# Example: If your current PIN is 0000 and you want to change it to 5678 → *247*0000*5678#
- Press the call/send button.
- You will receive a confirmation SMS if the change is successful.
PIN Tips:
- Choose a 4-digit PIN that is easy for you to remember but hard for others to guess.
- Avoid simple combinations like 0000, 1234, 1111, or your birth year.
- Keep your PIN private — never share it with anyone.
