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

Please perform a Reset MOBILE Network Settings

You won't lose any data by doing this and your network(s) will automatically update your APNs.

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

I can appreciate how frustrating this must be for you. 

Good troubleshooting step provided by @Piper123  👍

As well as this you could try >

Run the diagnostic tool in your Samsung Members App to see if that highlights anything. 

Can you test your sim in another phone as a process of elimination. 

And if possible try another Sim card in your own phone. 

Clear Cache Files from the phone's System Partition Section  > https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ You may need to insert your earphones or hook upto a powered On Laptop or use a Tv's USB Port to access the Clear Partition Section. This may help with lag or stutters as this clears the phone of old/unused or broken cache files.There is also a Repair Apps option in the Menu System too { Possibly excluding the s²⁴ Series of phone's } 

If you perform a forum search you may find existing threads with some further help or guidence within.  

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