How to Check if Someone is Sharing Your Data on Glo in Nigeria (2025 Guide)

With the rising cost of living and the increasing need for mobile data in Nigeria, keeping tabs on your data usage has never been more important. Whether you’re streaming movies, working remotely, or attending online classes, data runs everything. But imagine loading your phone with 10GB only to see it vanish in a matter of days. If you’re using Glo, there’s a chance someone might be sharing your data without your consent. Don’t worry, this post will walk you through how to check if someone is sharing your Glo data, how to remove them, and how to secure your line moving forward.

Why You Should Monitor Your Glo Data Usage

Nigeria’s economic challenges in 2025, coupled with increasing data demands for work, school, and entertainment, mean that every MB counts. The days when you could carelessly burn through data are long gone. Unauthorized data sharing can:

Deplete your bundle quickly
Interrupt essential online tasks like Zoom meetings or job applications
Lead to unexpected expenses when you need to buy more data

Understanding and controlling who is sharing your data ensures you’re getting full value for your money and not footing the bill for someone else’s YouTube binge.

Step-by-Step Guide: How to Check if Someone is Sharing Your Data on Glo

Glo provides several ways to manage and monitor data-sharing activities. Whether you’re a smartphone user or prefer USSD codes, you have options.

1. Use USSD Code to Check Who Is Sharing Your Data

USSD is the quickest and most accessible way to check.

Steps:

Dial *127*00# on your Glo line
A message will be displayed and sent to you listing all the numbers sharing your data
Review the list carefully. If you see a number you didn’t authorize, that’s your red flag

This method works on all types of phones and doesn’t require an internet connection.

2. Check via the Glo Café Mobile App

For those who want a more visual experience with better control:

Steps:

Download the Glo Café App from Google Play Store or Apple App Store
Launch the app and sign in with your Glo number
Tap on “Data” > “Manage Data Sharing” or “Shared Users”
You’ll see a complete list of all the phone numbers currently linked to your data
From here, you can remove or block any number with just a few taps

The app is user-friendly and provides additional features like data usage tracking, subscriptions, and customer support.

3. Monitor Your Data Balance for Unusual Activity

Even if you don’t suspect unauthorized sharing, it’s good practice to monitor your usage.

Steps:

Dial *127*0# to check your current data balance
Compare it to your actual usage habits

If your data is depleting faster than normal and you haven’t been downloading movies or running software updates, it could mean someone is sharing your plan.

What to Do If Someone Is Using Your Glo Data Without Permission

Discovering unauthorized usage can be annoying, but the fix is easy.

1. Remove the Number Using USSD

If you identify a suspicious number:

Steps:

Dial *127*02*[number]#
Replace [number] with the full phone number (e.g., 12702*08051234567#)
You will get a confirmation that the number has been removed

2. Remove via Glo Café App

Steps:

Open the Glo Café app
Go to Data Sharing Settings
Tap on the number you want to remove
Confirm to unlink or block the number

3. Contact Glo Customer Support

Still having issues? Then it’s time to bring in Glo support.

Call 121 from your Glo line
Explain the issue and request a full reset of data-sharing settings
You may be required to verify your identity

Alternatively, visit a nearby GloWorld Center for physical assistance.
