Has your LTE connection lately failed you? Or stopped working all together? Do not worry! There are several solutions you can try before you blow up your carrier's customer support line.
However, the first thing you should know is that 4G and LTE are two different things, though vendors often bundle them together. LTE actually achieves lower top speeds than "true 4G". So if you only see the 4G icon instead of 4G LTE in your status bar, this does not indicate a worse connection. But on the contrary. If you're in or out of a big city, your network may have real 4G features and speeds, so there's no need for a fix.
If you fall down to 3G or LTE disappears in familiar locations, the problem may be in your phone or network. You can do the following if LTE does not work on your phone.
Turning Airplane Mode On and Off
Sometimes the most obvious solution is the most reliable one. If your mobile data is causing problems, the first thing you should do is turn airplane mode on and off. You can do this simply by dragging the notification bar down and tapping the airplane icon, or by tapping Settings.
The paths may vary slightly depending on your version of Android. However, you can usually enable airplane mode by going to Settings> Wireless & networks> Airplane mode , Turn it on for at least a few seconds and then turn it off. In many cases, your LTE connection problems will be lost.
Restart your device.
If switching the airplane mode did not solve your problem, it's time for another proven move – restarting your device. Just press and hold the on / off button on your smartphone, and then tap Restart. Wait a few seconds and turn it back on. Check your status icon, but also test the speed of your LTE connection by opening some websites or downloading smaller apps.
Make sure the correct network mode is enabled.
Depending on your smartphone and carrier, there should be at least three types of connections – 2G, 3G and 4G LTE or just LTE. Usually, your device will attempt to connect to the fastest option, if available. However, if you have worked on your settings or have recently installed an update, it may need to be manually adjusted. Proceed as follows:
- Go to Settings and then tap Mobile Network .
- Select Network Mode . A pop-up list of preferred modes is displayed.
- Tap the Auto or LTE option.
Remove and re-adjust your SIM card If you did the trick, the problem could be in a poorly positioned SIM card. Throw it out and put it back in the drawer carefully. Be careful when inserting it back into your device. Once you're done, your LTE connection should be back to normal.
Verify that you are using the correct SIM slot.
Certain dual-SIM phones only support LTE in one of the two available SIM slots. If you insert the wrong SIM card without realizing it, LTE may not work. Try to slide the SIM card into the other slot.
Reset Network Settings
When you've done all of the above, but nothing has changed, it's time to take a slightly more drastic step. Reset your network settings. Do the following:
- Go to Settings and search for either Reset or Backup and Reset. Touch it.
- Tap Reset Network Settings in the list. Note that this step deletes all network settings, including stored Wi-Fi networks, paired Bluetooth devices, and so on. If you are sure you want to continue, tap Reset Settings .
- You will be asked to enter your PIN if you have one. Do this and confirm resetting your network settings.
After doing this, wait a few minutes – new network settings should be automatically applied from your phone. If nothing happens, a good old restart is always an option, but in the end, your LTE connection should be back to normal. Resetting to factory defaults is always an option, but do not resort to it if you have not done anything else before.
