If you have multiple data bundles active, the bundle with the least validity is used first. For example, if you have a 30-day bundle and a 60-day bundle both active, the 30-day plan is used before the 60-day plan.

How to renew your expired data (and save unused MBs)

Data rollover on MTN Nigeria means that unused data from your current bundle can be carried forward to your next bundle, provided you renew within the permitted grace period.

Monthly plans have a 7-day grace period, weekly plans have 3 days, and daily plans have 1 day. This grace period lets you renew and retain your remaining balance.

You can only roll over unused data if you renew with a plan from the same category, for example, monthly bundles with monthly bundles.

To renew quickly:

• Dial *312*1# or *904# and select your preferred data plan via USSD.
• Send the bundle keyword to 312 via SMS.
• To set auto-renewal, send R + bundle code to 312.

What are the common issues you might encounter?

USSD code returns no response or times out

First, check your signal strength and restart your phone. If codes still fail, send "BAL" to 131 or call 300 for customer support.

Balance shows zero after buying a bundle

Wait 1–2 minutes for activation. If still zero, dial *323# to confirm the subscription was successful, or check the MyMTN app for the active bundle.

Data finishes faster than expected

Some apps use data in the background even when you are not actively using your phone — examples include WhatsApp auto-downloads, Google Photos syncing, email refresh, and social media preloading content.

Night data not showing in balance check

Check after 11 pm. Night data only appears in balance checks during its active hours.

Bonus data seems to be ignored

Data usage follows a priority system depending on the type of bundles you have. In some cases, the system may switch between bonus and main data based on usage rules, expiry dates, or bundle type.

FAQs

What is the expiry date for MTN data bundles?

Data plans have expiry dates because each bundle comes with a set validity period that defines how long you can use it. This helps ensure fair network usage, allows for flexible pricing (shorter plans cost less), and enables features like renewals and promotions. Daily plans last 24 hours, weekly plans last 7 days, and monthly plans last 30 days.

Why does my data plan expire before I finish it?

All data bundles come with a fixed validity period, and any unused data expires once that period ends. Background apps, updates, streaming, downloads, or hotspot usage can consume data shortly after activation, making your bundle appear to vanish faster than expected.

What is MTN XtraBuy? The unique payment feature and how to use it

Which MTN bundles don't expire?

Currently, no MTN Nigeria prepaid data bundle is truly non-expiring. All data bundles you purchase have unique expiry dates. However, the Always-On monthly plans allocate data on a daily basis, reducing waste. You can roll over unused data from an Always On plan, if you buy any Access data bundle of 30 days or more, or buy the same Always-On plan again.

How do I renew my expired data?

Any unused MB does not roll over to a new plan unless you renew before expiry. MTN's auto-renewal feature can be enabled in the MyMTN app to prevent this. If your bundle has just expired, act within the grace period: you must renew your data plan before it expires or within the allotted rollover grace period after expiry. Dial *312# to buy a new bundle from the same category.

Will bonus data and night data still expire?

Yes, always. You will NOT be able to roll over any unused bonus data even if the bundle auto-renews before expiry, upon expiry, or within the applicable rollover period. For night data specifically, the data is strictly for use between 11 pm and 6 am, and any unused night data expires at 6 am and cannot be rolled over."
