Cheapest MTN Data Plan in 2025

Are you still buying data using *312# and selecting regular bundles? You might be spending more than you should. In 2025, smarter, cheaper data options are available across MTN and other major networks in Nigeria—you just need to know the right codes.

This guide breaks down the best and most affordable data codes for MTN, categorized into 30-day, 14-day, and 7-day plans. Whether you're on a tight budget or just want better value for your money, you'll find options that work.

Let’s explore the top picks.

1. MTN’s Best Value Data Offer: 31288#

Code: *312*88#

Offer: 1GB + 500MB for ₦200

Validity: 30 days

How it works:

You can activate this multiple times to stack up your data. For example:

₦1,000 = 7.5GB

₦3,000 = 22.5GB

This is significantly cheaper than MTN’s standard data plans. It requires a bit more effort but offers great value in the long run.

2. All-in-One Bundle (Data, Calls & SMS): 31210*1#

Code: *312*10*1#

Includes: Data + voice minutes + SMS

Ideal for: Users who need a balance of browsing and calling

Plan options:

₦3,000: 10GB + 100 minutes + 100 SMS

₦5,000: 20GB + 300 minutes + 100 SMS

₦10,000: 50GB + 750 minutes + 100 SMS

Note: These offers are often reserved for users with active LTE SIMs. If your SIM is not 4G-enabled, you may not see this option.

*3. Personalized Smart Data Offers: 121# → Smart Data

Code: *121# → Select "Smart Data"

Plan type: Custom offers based on your usage

Plan duration: 7, 14, and 30 days

These deals are generated based on your SIM's call and data history. You might get offers like:

80GB for ₦14,000

110GB for ₦16,000

114GB for ₦25,000

Check back regularly as the offers change frequently.

*4. Top Deals for You: 121# → 1

Code: *121# → Press 1

Offer type: Time-sensitive deals and promos

MTN occasionally provides special promotions under this menu. Examples include:

4GB + 2 voice minutes for ₦2,000

Discounted bundles based on your recharge or browsing history

These deals vary from SIM to SIM and aren’t always available.

*5. More Data Offers: 121# → 2

Code: *121# → Press 2

Offer type: Additional personalized data plans

Possible plans may include:

14GB for ₦3,000

Again, these offers are dependent on your SIM’s usage pattern, so not everyone will see the same options.
