1. Restart your phone

The easiest and often the most effective way to resolve a no service or signal issue on an Android or Samsung phone is to restart it. Doing so will reset any processes that may be interfering with your device's performance. Here's how:

Turn off your device.

Once the phone is off, wait 30 seconds and turn it on.

Check to see if this fixed the issue once it reboots.

2. Turn Airplane Mode on and off

Still having problems? Try to manually connect to your service provider. All you need to do is to turn Airplane Mode on and then back off to re-establish a connection. This resets the device in case it lost connection to a signal tower. To do so, simply pull down from the top of your Home screen to reveal Quick Settings and tap Airplane mode to turn it on, then tap it again to turn it off.

3. Manually select your network providers

It's possible that your device is having trouble finding your network, and you have to select it yourself.

Go to Settings> Connections > Mobile networks > Network operators. A list of network providers should show up. Select yours and see if this fixes your problem.

Regards,

Will
