You're paying too much for data relative to what you're getting, but you don't want to lose a number your contacts know, your bank accounts are tied to, your WhatsApp is registered on, and every OTP in your life is sent to. The good news is that you have several options — from switching your tariff plan within the same network, to buying cheaper SME data from resellers — none of which affect your SIM or number in any way. This guide covers all of them, network by network, with the exact codes to use and what to check before confirming any change.

Quick Answer

The fastest way to reduce your data cost without changing your number is to switch to a cheaper tariff profile on your current network using its USSD migration code, or to buy SME data from a trusted third-party reseller rather than directly from the network at full retail price. Both methods keep your number intact, your contacts reachable, and your bank OTPs unaffected. If the problem is the network itself rather than the plan, number portability (MNP) lets you move to a completely different network while keeping the same phone number — covered in a dedicated guide in this series.

What "Migrating a Data Plan" Actually Means

In Nigerian telecom, "migration" has two distinct meanings and it's worth separating them clearly before doing anything, since acting on the wrong definition can cost you bonuses or result in no change at all:

Tariff plan migration — changing your underlying account profile, which determines how you're charged for calls, SMS, and data subscriptions. For example, moving from MTN Pulse to MTN XtraTime, or from Airtel SmartCONNECT to Airtel Flexi. This is a one-time profile change that affects all future charges on your line until you migrate again.

Bundle migration — simply buying a different size or type of data bundle next time you subscribe. This isn't actually a migration in the technical sense — you just buy a different bundle next month. No USSD migration code is needed; you just select a different option when subscribing.

Most people who want "cheaper data" don't need to change their tariff plan — they need to either buy a better-value bundle or switch to SME data. The sections below cover both.

MTN — How to Check and Change Your Tariff Plan

Check your current MTN tariff plan: Dial 1231# and the response will show your current plan and options available for migration.

MTN tariff migration codes:

Target Plan Migration Code
MTN Pulse *406#
MTN XtraTime *408#
MTN TruTalk+ *420#
MTN BetaTalk *402#
MTN Family & Friends *310#

After dialling the migration code, confirm the switch when prompted. Most MTN tariff migrations take effect immediately.

Important MTN migration rules:

  • You can only migrate once every 24 hours
  • Some promotional bonuses attached to your current plan may be forfeited when you migrate — check what you'll lose before confirming
  • Airtime balance and data bundles already purchased carry over after migration

The cheaper data route on MTN — SME bundles: For most users, the bigger saving comes from buying MTN SME data through a reseller rather than changing tariff plans. SME data costs significantly less per GB than direct MTN purchases, uses the same MTN network, and doesn't require any plan migration. Ask a trusted data reseller or check platforms like VTpass or Gsubz for current SME data rates. The tradeoff: validity periods and customer support go through the reseller rather than MTN directly.

Airtel — How to Check and Change Your Tariff Plan

Check your current Airtel plan: Dial *141# and select the option to view your current tariff or manage your account.

Airtel migration: Dial *123# to access Airtel's full self-service menu, then navigate to "My Account" or "Change Plan." Airtel's migration options vary by account type and region — the menu will show which plans are available to your specific number.

Common Airtel plans and their general positioning:

  • Airtel SmartCONNECT — entry-level, best for calls and basic data
  • Airtel Flexi — flexible pay-as-you-go
  • Airtel Biz — business users, bulk data focus

Important Airtel migration rules:

  • Airtel sometimes enforces a 30-day waiting period before allowing re-migration to a previously held plan
  • Check if your current plan carries a loyalty bonus or special data reward before migrating away from it
  • Data bundles purchased on your current plan remain valid after migration

Cheaper Airtel data via SME: SME data on Airtel follows the same reseller model as MTN — same network coverage, cheaper per-GB rate, different delivery and support channel. Ask your data vendor specifically for Airtel SME rather than direct Airtel bundles.

Glo — How to Check and Change Your Tariff Plan

Check your current Glo plan: Dial *100# to see your current tariff plan, or dial *777# for the full Glo self-service menu.

Glo migration:

Target Plan Migration Code
Glo BetterMe 1001#
Glo Per Second Billing 1002#
Glo Jollific8 1008#

Glo's migration menu is accessible through *100# — select the plan you want to switch to and confirm. The new plan typically activates within a few minutes.

Important Glo migration rules:

  • Glo is known for aggressive promotional data bonuses tied to specific tariff plans — migrating away from a plan can forfeit accumulated bonuses that aren't clearly displayed at migration time
  • Confirm your bonus balance via 1245# before migrating, since forfeited bonuses cannot be recovered
  • Glo's per-GB rates vary significantly between tariff plans and can make a meaningful difference to your effective data cost

Cheaper Glo data: Glo's SME reseller market is less developed than MTN's, but data resellers do offer Glo bundles. Glo itself also runs aggressive promotional bundles tied to specific recharge amounts — recharging ₦500 or ₦1,000 during promo periods often attracts double or triple data bonuses that standard monthly subscriptions don't include. Checking 1270# after every recharge to see if a bonus was applied is worthwhile on Glo specifically.

9mobile — How to Check and Change Your Tariff Plan

Check your current 9mobile plan: Dial *200# or *244# to access 9mobile's self-service menu and view your current tariff.

9mobile migration: 9mobile's tariff plans include EasyStarter, EasyCliq, EasyLife, and EasyBliss, among others. To migrate, dial *200# and navigate to the "Change Plan" or "Manage Account" option.

Important 9mobile rules:

  • 9mobile has the smallest subscriber base among Nigeria's four networks, which sometimes affects network coverage in less-dense areas — if you're primarily in a major city, 9mobile's urban coverage is competitive; outside major cities it's worth confirming signal quality before committing
  • SME data resellers for 9mobile exist but are less common than MTN or Airtel — check availability with your vendor specifically
  • 9mobile's "Social Bundles" (dedicated WhatsApp, Facebook, or streaming data at low rates) can be a cost-effective supplement to your main data bundle if the majority of your daily usage is social media rather than general browsing or downloads
  • 9mobile offers daily, weekly, and monthly bundles — if your data usage is inconsistent month to month, the weekly subscription option lets you pay only for the weeks you actually need heavy data, which can be significantly cheaper for low-use months

Before You Migrate — A Quick Checklist

Run through this before confirming any tariff plan migration, since some of these checks take under a minute and can save you from forfeiting value you've already paid for:

  1. Check your current bonus data balance — use 1245# on Glo, 1314# on MTN (look for "bonus" entries), or *123# on Airtel. If you're sitting on a significant bonus balance that will be forfeited, it may be worth waiting until it's consumed before migrating.
  2. Check your data bundle expiry — if your current bundle expires in three days and you're migrating to a plan with different bundle pricing, waiting three days means you switch with a clean slate rather than mid-bundle.
  3. Confirm whether your new plan's data rates are actually cheaper per GB — some plan migrations look attractive but only offer cheaper rates on specific bundle sizes. Run the per-GB maths before confirming: divide the bundle price by the GB size and compare.
  4. Confirm bank OTP will still work — bank OTPs go to your phone number, not your plan. Migrating your tariff plan has no effect on OTP delivery whatsoever.
  5. Save a record of what you're migrating from — dial your current tariff check code and screenshot or note the plan name before migrating. If you're not happy with the new plan, you'll need the old name to migrate back.

The SME Data Option — The Fastest Way to Reduce Your Bill

Regardless of which network you're on, buying SME data from a reseller rather than directly from the network is often the single biggest lever for reducing your monthly data cost, without changing your number or your plan.

How it works:

  • Licensed data resellers buy bulk data from the networks at wholesale rates
  • They sell it to consumers at prices lower than the networks' own retail bundles
  • The data uses exactly the same network coverage, speed, and reliability as directly purchased data
  • You subscribe to a bundle from the reseller's platform (WhatsApp, app, or USSD) and the bundle is credited to your SIM

What to watch for:

  • Only buy from established resellers — your payment should clear and your data should arrive within minutes. If a reseller can't provide proof of delivery or disputes a failed transaction, treat that as a red flag.
  • SME data may not stack with all direct-network bundles — confirm how your existing bundle and the SME data will interact before buying
  • Some resellers' bundles have different validity periods from the network's own standard bundles for the same size

What You Keep and What You Might Lose When Migrating

Tariff Plan Migration Switching to SME Data Number Portability (MNP)
Phone number Kept Kept Kept
Existing data balance Usually kept Kept Lost — ported account is clean
Airtime balance Kept Kept Lost
Loyalty bonuses/rewards Often forfeited Kept Lost
Promotional data bonuses Often forfeited Kept Lost
Bank account linkages Unaffected Unaffected Unaffected after update
WhatsApp registration Unaffected Unaffected Unaffected

The bank account point is worth spelling out: your phone number is linked to your bank account for OTP and transaction alerts. When you change tariff plans within the same network, or switch to SME data, your number stays the same and nothing about your banking setup changes. Even with MNP (porting to a different network), your number stays the same — you simply need to update the new network's details if your bank requires the network operator name rather than just the number.

When to Just Port Instead (MNP)

If your problem is network quality — poor signal, frequent drops, consistently slow speeds in your specific area — switching tariff plans or buying SME data won't fix it because both still use the same network infrastructure and transmission towers. In that case, the right move is number portability (MNP), which lets you move to a completely different network while keeping your exact phone number, your contacts, your bank OTPs, and your WhatsApp — everything tied to that number continues working. Article 30 in this series covers the MNP process step by step.
