Saving mobile data became serious for me the day my bundle disappeared before noon. I had bought a fresh plan the night before and felt safe. By the next morning, my apps weren’t working. I rechecked my data balance, hoping it was a mistake. It was not. My data had quietly slipped away.....TAP TO CONTINUE READING

That moment made me realise what was eating my bundle. I checked my settings, reviewed my apps, and even searched online groups where people shared hidden USSD codes and tricks. That was when it clicked. Data does not just vanish. Your phone, your habits, and the network you use all play a part.

This article shows you how to make your bundle last longer and how to get better value on MTN, Airtel, Glo, and 9mobile.
How to stop your phone from wasting data

Saving data starts with your phone settings. These controls work on MTN, Airtel, Glo, and 9mobile, and they give you the quickest results.
1. Use your phone’s built-in data saver

Your phone already has tools that help you cut down on background data.

On Android, you can turn on Data Saver in Settings > Network and internet > Data Saver.
On iPhone, the option is called Low Data Mode. Once it is on, your apps stop using data quietly in the background. This is typically found under Settings > Mobile Data/Cellular/Service > Mobile Data Options > Data Mode

Some apps still need steady access, so you can allow a few important ones, like WhatsApp or your bank app, to bypass Data Saver. This is found inside the same menu under Unrestricted data.

Battery Saver also helps because it forces many apps to slow down their background activity. So you save data and keep your phone on for longer.
2. Control how your apps behave

Many times, the apps on your phone use more data than you expect. You can check this in your Data Usage settings. Once you see the apps consuming the most data, turn off their background access if they are not important.

You can also reduce notifications from apps that constantly refresh. This small change helps your data last longer.

Another key step is making sure updates only happen on Wi-Fi. Set your Play Store or App Store to update apps on Wi-Fi only. Do the same for WhatsApp, Telegram, and similar apps so they do not auto-download large photos and videos on mobile data.
3. Reduce how much your browsing and streaming consume

Streaming uses plenty of data. Download content on Wi-Fi and watch it later. If you must stream, lower the quality inside each app.
You can also use browsers that compress data. Opera Mini is popular because it reduces the size of pages and images. Chrome has a data-saving mode too. For maps, download offline maps so you can navigate without using your bundle.

These simple fixes give you stronger control over your data and help your bundles last much longer.
How to save mobile data on MTN Nigeria

Saving data on MTN works best when you combine the right phone settings with the cheaper, personalised bundles MTN hides inside its menus and promotions.
1. Use MTN’s official tools and codes

MTN gives you different ways to monitor your data. You can check your usage through the myMTN NG app, the USSD code, or Zigi on WhatsApp and Telegram. The official code for buying data is *312#, and you can check your balance with *323#. MTN also advises you to use Lite versions of apps and turn off Background App Refresh to reduce how much your phone consumes in the background.
2. Take advantage of personalised and hidden bundles

MTN users save the most when they stop depending on the standard plans in the *312# menu. According to the YouTube channel, Kidkes, they point out that MTN reserves its best Naira to Gigabyte offers for personalised sections like Data4Me and Pulse. This is why many users visit social media groups and forums to exchange USSD codes that unlock cheaper bundles. MTN sets the segments, but the community spreads the codes that help people find the highest value plans.
Vetted promotional codes

Some of the widely shared MTN offers include:

4GB for N1000 (Monthly): Access via specialized codes, such as *312*65*3#
2GB for N200 (Weekly): Access via specialized codes, such as *312*65*2#

These codes depend on eligibility, region, and availability, but I have used them repeatedly.

Your best strategy is to keep checking “offers” inside the MTN app and test the popular codes circulating online until you find the ones your line accepts.
3. Pick targeted bundles that match your usage

If most of your data goes into social media, MTN has small, focused plans like the Ayoba Weekly Plan (40MB for N50) and the All Social Daily Plan (200MB for N100). These plans help you reduce how much of your main bundle gets consumed.

You can also choose MTN monthly plans that come with a large All Night Streaming allowance, such as 2GB of night data. Using this night window for heavy tasks like big downloads, system updates, and long streaming sessions lets you stretch your main data during the day and get more value from what you paid for.
How to save mobile data on Airtel

You can save a lot of data on Airtel by choosing bundles that match what you actually use and by looking for non-standard promotional codes shared online.
1. Use Airtel’s standard plans the right way

The main code for buying Airtel data is *312#. Through this menu, you will see daily, weekly, and monthly plans. Airtel’s biggest savings feature sits inside its Smart Data Plans. These plans split your data into different parts so your heavy activities do not drain your main balance.

For example, one Smart Data Plan can give you 1GB of main data, 1GB for YouTube Night, and 200MB for Spotify. This setup helps you stretch your data by moving high-consumption activities into the dedicated sections of the bundle.

The best way to save on Airtel is to look at how you actually use your phone. If you stream a lot of video, a plan with a large YouTube allowance, even if it is timed, will save you more money than a regular volume-based plan. Airtel designed these plans to match different habits, so your savings depend on how well you choose.
How to save mobile data on Glo Nigeria

Glo helps you save money by buying larger bundles and making full use of the bonus data that comes with them. The network encourages you to control your usage through your phone settings and through smart scheduling of heavy activities.
1. Follow Glo’s advice on control and capping

Glo recommends using universal technical steps and setting firm limits on your device. You can manually cap your data by going to Settings > Network and Internet > Data Usage > Billing Cycle. This hard limit protects you from overspending, especially since Glo focuses on high-volume plans. You should also turn on data alerts so your phone warns you before you reach your limit.

To buy Glo data, the standard USSD code is *312#. To check your balance, you can dial *323#or send INFO to 127. Glo also advises you to turn off auto updates, stop multimedia auto downloads, and follow the Download It, Don’t Stream It approach to reduce waste.
2. Make the most of Glo’s volume and night bonuses

Glo offers its best unit prices when you buy in bulk. Daily and weekly bundles usually have a higher cost per MB than larger monthly or Mega Data Bundles. For example, a 30-day plan that gives you 10.5GB for N3,000 offers a better rate than smaller short-term plans. Because of this, bulk buying is usually more reliable than searching for secret codes that may not work for everyone.

Many Glo plans also include strong night bonuses. These bonuses usually work between 12 am and 5 am. The N2,000 monthly plan, for example, gives you 3.25GB of core data plus a 3GB night bonus. You get the best savings when you move system backups, large app updates, and video downloads to this night window. This lets you use bonus data that does not cost you extra.

Glo users who stay disciplined with night bonuses and bulk bundles get the most stable and consistent savings on the network.
How to save mobile data on 9mobile (now T2)

9mobile users save the most by staying strict with device settings and by using the strong night data that comes with many of the monthly plans.
1. Stay consistent with technical controls

Since 9mobile does not offer many widely shared hidden codes compared to the bigger networks, your main savings come from how well you manage your phone. You need to keep Data Saver on, limit background sync, and monitor your usage often. These universal technical fixes help you catch apps that consume too much data. Your phone’s built-in tools make it easy to check which apps are draining your bundle so you can stop the issue early.
2 Use 9mobile’s night data and mega packs

The biggest savings on 9mobile appear in the monthly plans that give a large part of the total data as night data. These night data ratios help you cut costs when you move heavy activity to off-peak hours.

Favorable night bonus ratios: Some 9mobile plans offer strong value when you use the night component properly. For example, certain monthly plans give you 6.2GB total data, with 4GB dedicated to night use, for ₦1,176. This breakdown makes it easy for you to plan how much cheap night data you can spend on downloads and updates.
Bulk and long-term value: If you use a lot of data, the 9mobile Mega Packs give even more savings. These bundles can be accessed using *452#, such as the offer of 10GB for N5,000 with 30 days validity. These larger bundles reduce the unit cost and provide predictable value.

To buy data on 9mobile, use the standard code *312#. To check your data balance, dial *323#. Since 9mobile focuses on structured plans instead of secret promotional codes, your savings remain stable and are less affected by sudden changes or regional limitations.
