| How to Check If Your Glo SIM Is 4G or 5G Ready (2025 Guide) |
Is your Glo SIM compatible with 4G or 5G? This 2025 guide explains how to check your Glo SIM readiness for faster networks and what to do if you need an upgrade.
Why Check If Your Glo SIM Is 4G/5G Ready?
Glo’s 4G LTE and expanding 5G coverage in Nigeria offer faster internet speeds, smoother streaming, and better call quality. However, not all SIMs or devices can access these networks.
Knowing whether your SIM is 4G or 5G compatible helps you:
- Avoid slow connections
- Upgrade in time
- Enjoy faster browsing and downloads
Method 1: Check Using Your Glo Phone Settings
Android:
- Go to Settings > Network & Internet > Mobile Network
- Tap on Preferred Network Type
- If you see options like 4G/5G, your phone supports it
- Insert your Glo SIM — if it doesn’t switch to 4G/5G, your SIM may not support it
iPhone:
- Go to Settings > Mobile Data > Voice & Data
- Options like 4G, LTE, or 5G Auto indicate your device is ready
- If Glo still shows 3G/EDGE, your SIM needs upgrading
Method 2: Use Glo USSD Code
Glo does not yet offer a universal code for SIM readiness, but you can try:
Dial *777#
Then select:
4 – Manage Plan > SIM Services (if available)
You may get a prompt like:
“Your SIM is already upgraded to 4G LTE.”
If not, you’ll be advised to visit a Glo outlet for upgrade.
Method 3: Visit a Glo Service Center
Take your SIM to the nearest Glo World Center and request a 4G/5G SIM check or upgrade.

Make sure your location supports 4G/5G before assuming your SIM is the issue.
