Fix Galaxy S7 Edge can’t connect to 4G LTE

These are the best possible fixed for the 4G LTE connectivity on your Galaxy S7 Edge. You are supposed to apply these solutions one by one. If one solution doesn’t work for you, the other will eventually work. Go ahead and fix Galaxy S7 Edge that cannot establish a 4G LTE connection.

Flight Mode must be turned off

First of all, you have to check the basic things on the phone. Pull down the notifications panel and check the Quick Toggles for Flight Mode. If the Flight Mode is turned on, turn it off immediately. If there is no Flight Mode icon in the quick toggles, open Settings > Connections > Flight Mode to check it.

Right SIM card should be selected for Mobile Data

If you are using a Dual SIM Galaxy S7 Edge having one SIM with Mobile Data and the other SIM without Mobile Data, it can cause a conflict. If the SIM without Mobile Data is selected as the preferred SIM card for Mobile Data, it will not let you use the 4G LTE. Follow these steps to fix this.

Open Settings > Connections > SIM Card Manager > Preferred SIM Card > Mobile Data > Select the right SIM card here.

Check the APN Settings

If the APN Settings are misconfigured, they can cause an issue. You can reset the APN Settings to see if this solution works.

1. Open Settings.
2. In Settings, go to Connections.
3. In Connections, go to the SIM Card Manager.
4. Click on the Network that you are currently using.
5. Now click on Access Point Names.

6. Restart the S7 Edge now.

Your SIM card must have 4G Data

Are you trying to connect to 4G without having Data? If that’s the case, it is absolutely not going to work. Check the Data Bucket first. If it’s empty, buy a good Data package and start using 4G after that.

The SIM card should not be damaged, it should be rightly inserted in the phone

Using a SIM Eject Tool, pull the SIM out of the phone and check it. The SIM should not be damaged. Place it carefully in the SIM tray and insert it back into the phone. Restart the phone after doing this. Check the 4G LTE connectivity now if it’s working fine or not.

If you are using an application to manage Data or Network on your phone, it can cause a conflict with the Mobile Data/4G. You can try disabling all the applications on your phone to check this. To do so, you will have to boot into the Safe Mode. Here is how to do this.

1. Turn off the Galaxy S7 Edge completely.
2. Power on the phone now.
3. As soon as you see the Samsung Logo, press the Volume Down button.
