Hello @toria1981 and may I extend a Warm Welcome to the Samsung Community Forum 👋 

May I ask does this issue happen everywhere or in a particular area 🤔 

You could also reset the Network Connections via Settings > General Management > Reset > Reset Network Connections.

Also sometimes removing the sim card and wiping the chip and referring it and or even try it in the secondary sim slot if a phone is dual sim can help. 

To see if the issue is the sim can you try it in another phone. 

If i can be of any further help please don't hesitate to ask  😎

Hey there and welcome to the Samsung UK and EU Community Customer to Customer Forum

Have you spoken to your network to see what signal is available in your area?

Have you also tried to reset mobile network settings on your device?

Perform this and your network will automatically send you a fresh set of APNs behind the scenes, takes a few seconds.

Then restart your device and see if things are any better.
