How to Switch from 3G to 4G on Glo Without Changing SIM (2025 Guide)

Learn how to upgrade your Glo line from 3G to 4G without changing your SIM card. Discover phone settings, USSD tips, and tricks to boost speed on Glo in 2025.

Why Switch from 3G to 4G on Glo?

Glo 4G LTE offers up to 10x faster browsing, improved video streaming, and stronger network stability than 3G. With Glo expanding its 4G and 5G coverage in Nigeria, switching to 4G can dramatically improve your mobile experience.

Step-by-Step Guide: Switch to 4G Without Changing Your Glo SIM

1. Check if Your Phone Supports 4G

Before upgrading your network:

• On Android:
  Go to Settings > Network & Internet > Mobile Network > Preferred Network Type
  Ensure options like 4G or LTE are available.

• On iPhone:
  Go to Settings > Mobile Data > Voice & Data, and select 4G or LTE.

If your phone doesn’t support 4G, you’ll need a compatible device.

2. Ensure Your Glo SIM Is 4G Ready

Some newer Glo SIMs already support 4G. Here’s how to check:

• Dial *777#
  Navigate to 4G SIM services if available.
  If no option shows, your SIM is likely old.

• Visit the nearest Glo World Store if unsure. If you have a 4G SIM, no need to swap.

3. Enable 4G on Your Phone

After confirming SIM and device readiness:

• Set Preferred Network Type to 4G/LTE
• Restart your phone
• Check the network bar — it should now display 4G or LTE

4. Use Glo 4G-Covered Locations

Make sure you’re in a location with Glo 4G coverage.

When You’ll Need to Change SIM

If your Glo SIM:

• Is older than 5 years
• Doesn’t support 4G after enabling settings
• Always shows 3G or EDGE

Then, visit a Glo center to upgrade to a 4G SIM for free.
