Alright, so you just got yourself an Ntel 4G LTE SIM card or any network’s (e.g GLO, MTN etc) 4G compatible SIM card and are looking forward to a pleasurable experience. You are very likely to experience some problems settings up on your 4G LTE enabled Android phone so I’ll highlight 3 common ones and how to resolve them.
1. No network / Emergency calls only
Before buying a 4G enabled phone, you need to be sure that your 4G SIM will actually work on the 4G phone ; in other words, the 4G band which your network supports needs to match what the phone supports. This is the most important factor when choosing a 4G phone to go with your new SIM card.
Even when you have a match, you might still run into no network issues or Emergency calls only (your SIM details gets detected but you don’t get signal).
This is likely as a result of you not setting the right network preference. You have two options (Option 2 is recommended):
1. Go to Settings > More > Mobile networks > Preferred network type > Set to 4G
2. Using Shortcut Master Lite to locate Engineer mode (root not required), navigate to Telephony > Network selecting > Select LTE only (you can select other options which include 4G if your network supports non-4G bands)
2. No internet / data connection
Now that you have signal, the next challenge would likely be no internet access even though you’ve purchased a data bundle. This is likely as a result of you not setting the right APN.
To resolve this, navigate to Settings > More > Mobile networks > Access point names > Tap the + icon > Fill in Ntel’s APN settings or your service provide’s APN settings (for non-Ntel users) > Tap the menu at the top (3 white vertical dots) and select Save > Back under APNs, ensure the newly created APN is ticked, checked or selected.
3. Still no 4G network or stuck with 2G / 3G network
Your phone now gets signal, you’ve purchased a data bundle, you have APN correctly setup, you’ve turned on mobile data (under Settings > Data usage) but still don’t get 4G. Instead, you only get 2G or 3G. This might either be as a result of your phone / service provider having 4G restrictions (I’ll address this in another article) or you not setting a primary SIM card.
You see, on some Android phones, only one particular slot (at a time) might support 4G. You could also experience this on some 3G Android phones where only one slot (at a time ) supports 3G.
To resolve this (If your phone is such), navigate to Settings > SIM cards > Select primary card > Select the SIM you want to use 4G on (in some cases, you’ll need to insert the SIM in that slot).
I’m unable to make or receive calls on my Ntel line
I experienced the same issue. I could get signal and surf the internet but could not make or receive calls. I also was unable to send out or receive SMS. What you need to do is install the Ntel VOXHD app at http://reserve.ntel.com.ng/ntel-vox-hd-app.apk and run it. You could set it to be your default dialer
