How to Upgrade Your MTN SIM from 3G/4G to 5G

The demand for faster internet speed has grown massively in Nigeria. With the arrival of 5G technology, MTN customers now have the chance to enjoy better connectivity, smoother streaming, faster downloads, and stronger network reliability. Many people still use 3G or 4G SIM cards and wonder how they can make the switch to 5G without stress.

Upgrading your MTN SIM is not complicated, but it requires certain steps. This article explains the process in detail, including how to confirm if your SIM and phone support 5G, the benefits of upgrading, the cost involved, and how to troubleshoot common issues after activation.

What is 5G and Why Upgrade?

5G is the fifth generation of mobile network technology. It is much faster than 4G and allows better performance for online activities like video calls, gaming, streaming, and downloading large files.

Benefits of upgrading include:

• Faster browsing and download speeds.
• Improved network stability in crowded areas.
• Low latency, making gaming and video calls smoother.
• Better support for smart devices and online businesses.

MTN is one of the first telecom companies in Nigeria to roll out 5G, making it accessible to customers in selected locations.

How to Check if Your MTN SIM is 5G Ready

Before starting the upgrade, you need to confirm if your SIM card is compatible.

Steps to check:

1. Dial *123# on your phone.
2. Select SIM Services.
3. Choose SIM Upgrade Check.
4. MTN will send you a message confirming if your SIM is 5G ready or not.

If your SIM is already 4G enabled, it is likely compatible with 5G, but in some cases, an upgrade may still be required.

How to Confirm if Your Phone Supports 5G

Not every smartphone supports 5G. Even if you upgrade your SIM, you won’t enjoy 5G services unless your phone can handle the network.

Steps to confirm:

• Check the phone specifications in the settings menu.
• Visit the official website of your phone brand and search for your model.
• If you are unsure, dial *123# on MTN and follow the prompts for 5G compatibility check.

Popular brands like Samsung, iPhone (iPhone 12 and above), Xiaomi, and some Tecno and Infinix models now support 5G.

Steps to Upgrade Your MTN SIM to 5G

Step 1: Visit an MTN Service Centre

Take your current SIM card and a valid means of identification (e.g., National ID, Voter’s card, or International Passport) to any MTN service centre or authorized partner store.

Step 2: Request for a SIM Swap/Upgrade

Inform the customer service agent that you want to upgrade your SIM to 5G. They will verify your identity and process the request.

Step 3: Collect Your New SIM Card

You will be given a new SIM card that supports 5G. In most cases, the phone number remains the same.

Step 4: Activate the SIM

Insert the new SIM into your phone. Dial *123# or restart your phone to activate it.

Step 5: Configure Your Phone Settings

Ensure your mobile data settings are switched to 5G. You can do this by going to Settings > Mobile Network > Preferred Network Type > 5G.

Cost of Upgrading to 5G SIM

MTN does not charge extra for SIM upgrades. The process is usually free, although some outlets may require a token (₦100–₦500) for administrative purposes.

How to Subscribe to MTN 5G Data Plans

After upgrading your SIM, you need an active data plan to enjoy 5G services. MTN provides different packages, including daily, weekly, and monthly options.

Examples of data bundles:

• 1.5GB for ₦1,000 (monthly plan).
• 2GB for ₦1,200 (monthly plan).
• 10GB for ₦3,000 (monthly plan).
• 40GB for ₦10,000 (monthly plan).

Dial *312# to subscribe to any of these plans.

How to Confirm 5G Coverage in Your Area

Even after upgrading your SIM and using a 5G phone, you need to be in an area where MTN has 5G coverage.

Steps:

1. Dial *123# and select Network Coverage Check.
2. Visit MTN’s official website to check updated coverage maps.
3. You will also see a 5G icon on your phone when connected.

Currently, MTN has rolled out 5G in major cities like Lagos, Abuja, Port Harcourt, and a few others. Expansion is ongoing across Nigeria.

Troubleshooting Common Issues After Upgrade

1. SIM Not Working:
   Restart your phone or visit an MTN centre if the SIM is not recognized.
2. No 5G Signal:
   Ensure you are in a 5G coverage area and that your phone supports 5G.
3. Slow Internet:
   Switch between airplane mode on and off to refresh the connection. You may also need to select 5G in network settings.
4. Activation Delay:
   Sometimes it takes a few hours for the new SIM to activate. Contact MTN customer care on 180 if it persists.

• Use 5G phones with strong battery capacity since the network consumes more power.
