If you’re searching for MTN unlimited data plan in Nigeria, the first thing to know is this: MTN does have unlimited broadband plans, but they are not the regular mobile data bundles most people buy on their phone line. They are tied mainly to MTN broadband router plans, especially eligible MTN 5G router setups, and they come with usage thresholds that can reduce your speed after heavy use.

So if you came here looking for a simple code for MTN unlimited data plan on your normal SIM, this is the honest answer: there is no regular all-purpose unlimited MTN phone data plan for every subscriber in the usual daily, weekly, or monthly mobile bundle list. What MTN currently offers instead are broadband unlimited plans for supported router devices, plus some large capped plans for heavy users.

That’s where many older articles get it wrong. They either mix up old HyNetflex information with MTN’s newer broadband plans, or they call every high-volume plan “unlimited” when it really is not.

This guide clears it up.

Does MTN have an unlimited data plan in Nigeria?

Yes, MTN Nigeria currently offers unlimited broadband plans, but they are not the same as the normal MTN data plans you buy on a phone with *312#.

At the time of writing, the main MTN unlimited plans are broadband router plans such as:

• Gold Unlimited – ₦40,000 for 30 days, with speeds up to 50Mbps, then reduced to 5Mbps after 400GB
• Diamond Unlimited – ₦65,000 for 30 days, with speeds up to 100Mbps, then reduced to 5Mbps after 800GB

MTN also lists router broadband plans like Silver and Ruby that still behave like “unlimited after FUP” style bundles on broadband devices, but the truly clear speed-based unlimited offers currently highlighted by MTN are the Gold and Diamond unlimited plans for eligible broadband customers.

So if your goal is simple:

• Want unlimited MTN data on your phone SIM? MTN does not currently advertise a standard mobile unlimited plan for everyone.
• Want unlimited MTN internet at home or office? You should be looking at MTN broadband router plans, not the regular phone bundle menu.

What most people mean when they search “MTN unlimited data plan”

In Nigeria, this search usually means one of four things:

1. A truly unlimited monthly MTN plan
2. An MTN MiFi or WiFi unlimited plan
3. A code to buy unlimited data on MTN
4. A big MTN plan that can handle streaming, downloads, gaming, CCTV, work calls, and multiple devices

These are not exactly the same thing.

That’s why it helps to separate MTN mobile data bundles from MTN broadband router plans.

MTN mobile data bundles

These are the usual plans you buy on your SIM for your phone. They include daily, weekly, monthly, bi-monthly and yearly bundles. MTN’s current standard mobile plans include options like 20GB, 25GB, 36GB, 65GB, 75GB, 165GB and 250GB, but they are capped bundles, not unlimited plans.

MTN broadband router plans

These are designed for MTN broadband devices such as supported 4G/5G routers and MiFi devices. This is where the unlimited plans live.

If you only read one part of this article, read that distinction carefully. It will save you from buying the wrong device or chasing the wrong code.

MTN unlimited data plan price in Nigeria right now

Below is the cleanest way to look at MTN’s current broadband unlimited options.

Current MTN unlimited broadband plans

MTN Plan	Price	Validity	What you get	Important limit
Gold Unlimited	₦40,000	30 days	Unlimited broadband plan, up to 50Mbps	Speed drops to 5Mbps after 400GB
Diamond Unlimited	₦65,000	30 days	Unlimited broadband plan, up to 100Mbps	Speed drops to 5Mbps after 800GB

These are the clearest MTN unlimited plans currently shown on MTN’s router broadband pages and unlimited plan terms.

---

Other MTN router plans people confuse with unlimited plans

You may also see these on MTN broadband router pages:

• Silver – ₦30,000 for 30 days, with 150GB FUP and then 2GB daily data drops after the main bundle is exhausted
• Ruby – ₦45,000 for 30 days, with 260GB FUP and then 2GB daily data drops after the main bundle is exhausted

These are still broadband plans and they are aimed at heavier users than normal phone bundles, but they are not the same as the speed-based Gold and Diamond unlimited plans.

This matters because many blog posts lump all of them together and just call everything “unlimited.” That creates confusion fast.

Does MTN have an unlimited monthly data plan for phones?

Not in the normal way most people mean it.

If by “monthly unlimited MTN data plan” you mean:

• buy it directly on your normal MTN line
• use it on your phone without a special router setup
• no cap, no threshold, no special device requirement

then MTN’s public mobile data bundle page does not currently show a standard phone-based unlimited monthly plan. Instead, it shows capped monthly bundles like:

• 7GB
• 10GB
• 12.5GB
• 16.5GB
• 20GB
• 25GB
• 36GB
• 65GB
• 75GB
• 165GB
• 250GB

Those are standard MTN data bundles, not unlimited phone plans.

So if you’re asking, “Does MTN have unlimited data plan for Android or normal MTN SIM?” the safest answer right now is:

Not as a regular public phone bundle on the standard MTN data menu.

---

MTN unlimited data plan code

This is where older posts usually become misleading.

There is no single regular mobile USSD code that gives every MTN user a normal unlimited phone data bundle.

Instead, MTN currently separates things like this:

For normal MTN mobile data bundles

You can browse data options via:

• *312#
• *312*1#
• sometimes *904# for supported bundle access

These are for regular MTN data plans, not a general unlimited phone bundle.

For MTN router broadband plans

MTN says broadband router plans can be subscribed to via:

• *312*500#
• *461*1#
• myMTN App
• myMTN Web
• Zigi
• MTN TopIt/VTU

These are the channels relevant to router broadband plans, including the unlimited router offers.

So if someone asks, “What is the code for MTN unlimited data plan?” the better answer is:

There is no general MTN unlimited phone-data code for every SIM. MTN’s unlimited offers are currently tied to broadband router plans, which are managed through router broadband channels such as 312500# or 4611# depending on the device and plan type.

That answer is more accurate than pretending there’s a magic “unlimited code” for every MTN line.

---

Which devices can use MTN unlimited plans?

This is one of the most important parts of the whole topic.

According to MTN’s current unlimited plan help pages and terms, MTN Unlimited Plans are exclusively available for use with MTN 5G Routers.

That means if you are using:

• a normal smartphone SIM only
• a regular phone hotspot
• a random modem that is not eligible
• an old setup from years back

you should not assume you can simply dial a code and activate Gold or Diamond Unlimited on it.

In plain English

If you want the current MTN unlimited plan, think router broadband, not regular phone bundle.

That’s the biggest shift from older MTN “HyNetflex-style” blog posts.

How to subscribe to MTN unlimited data plan

If you want the current MTN unlimited broadband option, here is the practical route.

Option 1: Subscribe through MTN router broadband channels

MTN says router broadband plans can be bought through:

• USSD: *312*500#
• USSD: *461*1#
• myMTN App
• myMTN Web
• Zigi
• MTN TopIt / VTU

Basic step-by-step

1. Make sure you are using an eligible MTN broadband device.
2. Confirm that the line inside the device is the one registered for the broadband service.
3. Dial *312*500# or *461*1# from the associated line if supported.
4. Open the router broadband plan section.
5. Choose the unlimited plan you want, such as Gold or Diamond, if it is available on your device/account.
6. Pay using the supported payment option.
7. Wait for the activation confirmation.

If the unlimited option does not show up, that usually points to one of these:

• the device is not eligible
• the line is not on the correct broadband setup
• the account is seeing only capped broadband plans
• MTN has changed plan visibility for that device category

That last point matters. MTN can adjust plan menus and device eligibility over time, so I always advise readers to confirm from the current broadband page or support if the exact unlimited option doesn’t show.

---

Option 2: Use the myMTN app for broadband plan purchase

If you hate navigating USSD menus, the app is usually easier.

The general flow is simple:

1. Open myMTN NG App
2. Sign in with the broadband line or linked account
3. Go to bundles or broadband/router plans
4. Look for router broadband plans
5. Choose the plan you want
6. Pay and activate

One thing most users don’t realize is that the app experience for phone bundles and router bundles can look different. So don’t assume that because you can buy normal 7GB or 20GB phone data inside the app, the unlimited router plan will sit in the same place.

MTN unlimited data plan for MiFi and WiFi: what is actually available?

This is another area where search intent gets mixed up.

People search for:

• mtn mifi unlimited data plan
• mtn unlimited data plan for wifi
• mtn modem wifi data plan unlimited
• mtn mobile wifi data plan unlimited

The honest answer is this:

MTN does have broadband plans for WiFi devices

Yes. MTN’s broadband ecosystem covers routers and MiFi-type usage categories. It also sells broadband devices like:

• 5G Broadband Router
• 4G Broadband Router
• 5G MiFi
• Broadband MiFi

But the current unlimited plans are tied more specifically to eligible router broadband setups

MTN’s own unlimited plan help page says the unlimited plans are exclusively available for use with MTN 5G Routers.

So if you’re asking whether every MTN MiFi can use Gold or Diamond Unlimited, don’t assume that.

This is the safer way to think about it:

• Need ordinary data for MiFi? MTN has capped router/MiFi broadband plans.
• Need the current unlimited broadband plans? Check whether you have an eligible MTN 5G router, not just any MiFi or WiFi device.

What “unlimited” on MTN really means

This is the part many readers care about most.

When MTN says unlimited, it does not mean:

• endless full-speed browsing forever with no policy attached
• a secret no-throttle plan
• a plan that behaves the same after 50GB, 200GB and 900GB

Instead, MTN’s current unlimited plans come with a Usage Threshold Policy.

MTN Gold Unlimited

• Up to 50Mbps
• After 400GB, speed can reduce to 5Mbps

MTN Diamond Unlimited

• Up to 100Mbps
• After 800GB, speed can reduce to 5Mbps

So yes, it is still marketed as unlimited because your connection does not stop after 400GB or 800GB. But your speed changes after that threshold.

That is the key trade-off.

Is 5Mbps still usable?

Yes, for many things.

At 5Mbps, you can still usually handle:

• web browsing
• WhatsApp
• email
• some SD or moderate streaming
• light work calls, depending on network quality

But it will not feel the same as the pre-threshold speed if you are doing:

• heavy 4K streaming
• very large downloads
• multiple gamers in the house
• many smart devices online at once

So when you compare MTN unlimited plans, don’t just look at the word unlimited. Look at the threshold too.

---

Is MTN unlimited data plan worth it?

It depends on how you use data.

It may be worth it if:

• you run home WiFi for several people
• you stream heavily on TV, laptop and phones
• you work from home and use Zoom, Teams, uploads and cloud backups
• you have a shop, office, lodge or CCTV setup
• you routinely burn through 200GB to 500GB and normal mobile plans no longer make sense

It may not be worth it if:

• you only use data on one phone
• your monthly usage is around 10GB to 60GB
• you’re chasing a cheap “unlimited” code for ₦500 or ₦1,000
• you don’t own an eligible broadband device
• MTN’s 5G or strong 4G broadband coverage in your area is poor

This is where I think many people overspend. They hear “unlimited” and jump in, when a 75GB, 165GB, or 250GB capped plan may actually suit them better for less money.

---

Best alternative if you don’t have MTN unlimited plan access

If you don’t own an eligible MTN broadband router, the practical alternative is to compare MTN’s largest regular data plans instead of chasing fake “unlimited cheat codes.”

Here are some of the higher-volume standard MTN bundles currently listed:

MTN regular plan	Price	Validity
65GB	₦16,000	30 days
75GB	₦18,000	30 days
165GB	₦35,000	30 days
250GB	₦55,000	30 days
150GB	₦40,000	60 days
480GB	₦90,000	90 days
800GB	₦125,000	365 days

These are not unlimited, but for some users they are the smarter option because:

• you can use them without moving into a full router-unlimited setup
• they may cost less than buying a new 5G router plus an unlimited bundle
• they can still cover very heavy monthly usage if managed well

---

MTN unlimited data plan for one month

If your question is specifically “How much is MTN unlimited data plan for one month?”, the clean answer right now is:

Main one-month MTN unlimited options

• Gold Unlimited – ₦40,000 for 30 days
• Diamond Unlimited – ₦65,000 for 30 days

But again, these are broadband unlimited plans, not standard all-SIM phone bundles.

---

Is there an MTN 1-day unlimited data plan?

I couldn’t verify a current MTN 1-day unlimited data plan on MTN Nigeria’s public data and broadband pages.

MTN’s public mobile data list includes daily plans such as:

• 75MB
• 110MB
• 230MB
• 500MB
• 1GB smart bundle
• 1GB + 1.5 mins
• 2.5GB
• 3.5GB

But these are daily capped bundles, not daily unlimited plans.

So if you saw an old article talking about MTN daily unlimited plan, be careful. It may be outdated, promotional, or simply inaccurate.

---

Can you use MTN unlimited data plan on a normal phone?

Usually, this is where expectations and reality clash.

If you mean buy the plan and use it like normal mobile data directly on your phone, MTN’s current unlimited plan documentation points to broadband router usage, especially eligible 5G routers.

If you mean connect your phone to a router that has the unlimited broadband plan, then yes, that’s a different story. In that case, your phone is simply one of the devices using the router’s internet connection.

That distinction is important.

---

How to check MTN unlimited broadband balance

For MTN router broadband balance checks, MTN lists these channels:

• *461*4#
• *312*500#
• myMTN App
• Zigi

If you’re on a broadband plan, use those broadband balance channels rather than the normal phone-data mindset.

Common mistakes people make with MTN unlimited plans

1) Assuming every “unlimited” MTN plan is for phones

It isn’t.

A lot of the current unlimited language sits inside MTN’s broadband/router ecosystem, not the ordinary phone bundle menu.

2) Ignoring the usage threshold

Unlimited doesn’t mean “same speed forever.”

Gold and Diamond both have thresholds. That matters if you are a very heavy user.

3) Buying a big plan without checking device eligibility

This one is expensive. You don’t want to buy a router hoping it will support an unlimited plan, only to find out you misunderstood the plan category.

4) Chasing fake “MTN unlimited cheat” offers

If a post promises:

• unlimited MTN data for ₦100
• unlimited MTN data for ₦150
• secret cheat code
• free unlimited browsing

be careful. Most of those posts are either outdated, misleading, or built around temporary loopholes that no longer work.

5) Ignoring coverage in your area

Even a good unlimited plan will frustrate you if the signal where you live is poor. A router plan makes more sense when MTN’s 4G/5G coverage in your home or office is actually solid.

---

My honest recommendation if you’re choosing between MTN unlimited and regular big bundles

If your usage is below 150GB a month, I would not rush into the unlimited broadband setup unless you already own the right router and you genuinely need home WiFi for several devices.

If your usage is consistently around:

• 200GB
• 300GB
• 400GB
• multiple people streaming and downloading every day

then MTN’s router-based unlimited plans start making much more sense.

That’s really the dividing line.

For one person on one phone, “unlimited” often sounds more necessary than it actually is.

For a family, shared apartment, office, gaming house, or business location, it can be a very different conversation.

FAQs About MTN Unlimited Data Plan

Does MTN have unlimited data plan in Nigeria?

Yes. MTN Nigeria currently has broadband unlimited plans such as Gold Unlimited and Diamond Unlimited, but they are tied to eligible broadband/router usage rather than the normal public mobile data bundle list for every phone line.

What is the code for MTN unlimited data plan?

There is no single general phone-data code that gives every MTN user a standard unlimited mobile plan. MTN’s broadband/router plans can be managed through channels such as *312*500# or *461*1#, depending on the plan and device setup.

How much is MTN unlimited data plan monthly?

The main monthly MTN unlimited broadband plans currently shown publicly are:

• Gold Unlimited – ₦40,000 for 30 days
• Diamond Unlimited – ₦65,000 for 30 days

Is MTN unlimited data really unlimited?

Can I use MTN unlimited data plan on my phone?

Not as a normal standard phone bundle in the way most people expect. MTN’s current unlimited plan terms point mainly to eligible broadband router usage, especially MTN 5G routers.

Does MTN have unlimited data plan for MiFi?

MTN has broadband plans for MiFi and router categories, but the current public unlimited-plan wording is specifically tied to eligible MTN 5G routers. So don’t assume every MiFi device can use the same unlimited plan.

Is there an MTN unlimited night plan?

I couldn’t verify a current public MTN unlimited night data plan on MTN Nigeria’s official data and broadband pages. MTN does have night-related data benefits on some regular bundles, but that is different from a standalone unlimited night plan.

Can I buy MTN unlimited data plan with airtime?

Broadband plan purchase channels depend on the specific device and channel being used. MTN lists router broadband subscription channels such as USSD, app, web and partner channels, but payment flow can vary by plan and setup. The safest move is to confirm within the active broadband purchase channel shown for your device.

How do I check my MTN broadband balance?

MTN lists broadband balance channels such as:

• *461*4#
• *312*500#
• myMTN App
• Zigi

What is the cheapest MTN unlimited plan?

Among the current clearly listed unlimited broadband options, Gold Unlimited at ₦40,000 is the cheaper one compared to Diamond Unlimited at ₦65,000.

Is MTN unlimited plan good for office use?

Yes, it can be, especially if you need stable internet for multiple users, meetings, uploads, downloads, CCTV, cloud tools, and daily heavy use. But it makes more sense when you have the right router setup and good MTN broadband coverage in your location.

What should I buy if I don’t need full unlimited data?

If you don’t need router-based unlimited broadband, consider MTN’s bigger capped plans such as 75GB, 165GB, 250GB, 150GB for 60 days, or 480GB for 90 days. They may be a better value depending on how much data you actually use.
