Enabling 4G or 5G on your SIM card allows you to enjoy faster internet speeds, better call quality (VoLTE), and smoother browsing. However, your SIM, phone, and location must all support the network type.
In Nigeria, major telecom providers such as MTN Nigeria, Airtel Nigeria, Globacom, and 9mobile offer 4G services, while 5G is available in selected locations and devices.
This guide explains how to activate 4G or 5G on your SIM step by step.
Requirements Before Enabling 4G or 5G
Make sure you have:
- A 4G/5G compatible smartphone
- A 4G/5G SIM card

Step 1: Check If Your SIM Supports 4G or 5G
Some older SIM cards only support 2G or 3G.
To check:
- Look for “4G LTE” or “5G” on your SIM pack
- Contact your network provider if unsure
You may need a SIM replacement if it’s not supported.
Step 2: Insert SIM Card Properly
- Turn off your phone
- Insert the SIM card correctly
- Turn the phone back on
- Wait for network signal
Step 3: Enable Mobile Data
- Go to Settings
- Tap Mobile Network
- Turn on Mobile Data
Without this, 4G/5G will not work.
Step 4: Select Preferred Network Type
On Android:

On iPhone:

Step 5: Confirm 4G or 5G Activation
Look at your signal bar:
