I don't have internet on my sim but I can make calls.

I have had a Samsung  S8 cell phone for a long time and I used it normally and without problems.

Now I changed its sim with another number and it doesn't get an internet signal but I can make calls.
Asked
Does anyone know what problem I have with my cell phone?

I await a response please.

@jnavv  You need to enter the correct APN settings on the device for that network.
