Glo 4G Network Settings and Compatibility
A phone can sit in a Glo coverage area, hold a perfectly good SIM and still refuse to show 4G. The reasons are usually simple: the phone does not support the right bands, a setting is limiting it to an older mode, or the area itself has no 4G signal at that spot.
This guide explains what 4G compatibility means, how to check your phone, which settings to look at and how to tell a phone problem from a network problem.
Band lists and network details change, so confirm what Glo uses in your area with Glo care, and check your phone’s specification sheet.
What 4G compatibility means
4G, also called LTE, runs on specific radio bands. For your phone to use Glo’s 4G, it must support at least one of the bands Glo uses where you are. A phone made for another region may support 4G in general yet miss the local bands, which leaves you on 3G or 2G even in a strong 4G area.
How to check your phone
| 1 | Find your exact phone model, in Settings under About phone. |
| 2 | Look up its specification sheet from the maker, which lists supported LTE bands. |
| 3 | Ask Glo care or a Glo centre which LTE bands the network uses in your area. |
| 4 | Compare the two lists and see whether at least one band matches. |
| 5 | Test the phone with a Glo SIM in a place known to have 4G. |
Settings that limit your phone
- Preferred network type set to 3G or 2G only.
- The wrong SIM selected for mobile data on a dual SIM phone.
- Power saving or data saver modes restricting the connection.
- Airplane mode toggled on by accident.
- Old or reset APN settings.
- A software update that changed the network mode.
How to set the preferred network mode
Open Settings, then Mobile network or SIM settings, choose the Glo SIM, and look for Preferred network type. Select the option that includes 4G or LTE, often labelled 4G, 3G, 2G auto. Restart the phone. On some phones the option is called Enable LTE or Voice and data.
Phone problem or network problem?
| Clue | Likely cause |
|---|---|
| Other phones on Glo show 4G in the same spot, yours does not | Phone compatibility or settings |
| No phone shows 4G there | No 4G coverage at that spot |
| 4G appears outside but not indoors | Indoor signal loss |
| 4G disappeared after an update | A setting changed |
| Your SIM shows 4G in another phone | Your phone is the problem |
Does an old SIM matter?
Very old SIM cards can sometimes limit what the phone can use. If your SIM is many years old and you never see 4G on any phone, ask Glo whether a replacement SIM would help. Replace it through an official channel and keep your number.
Tips to get the most from 4G
- Use the stronger spot in your home, near a window.
- Keep your phone software updated.
- Avoid cases with metal parts that block the antenna.
- Restart the phone after changing network settings.
- Check your data plan, since some plans slow down after the volume is used.
Questions people ask
No. It must support the bands used in your area, and the area must have 4G.
Signal type is only one factor. Congestion and your plan also matter.
No. Band support is built into the hardware.
Using a phone bought abroad
Phones bought from other regions are the most common cause of missing 4G. They may support 4G in general but lack the local bands, and some also lock features to the original market. Before you buy a second-hand or imported phone, ask the seller for the exact model number and check its band list against what Glo uses. Test it with a Glo SIM before you pay in full, if the seller allows.
Voice calls on 4G
Some phones need an extra setting to make calls while on 4G. If calls fail or your phone drops to 3G whenever you dial, check the VoLTE and HD call guide on this site, and look at your phone’s call settings.
Final word
Check your phone’s bands, set the right network mode, test in a known 4G spot and separate phone issues from coverage. If a compatible phone still never gets 4G in a covered area, report it to Glo with your model and test results.
What to tell Glo care
Call 121 and give your phone model, the place you tested, the label your phone shows, and what other Glo users nearby see. Ask for a ticket number. The more precise your details, the faster the agent can tell whether the problem is the phone, the settings or the area.
