I had the same issue, my 3G and wifi works but when enable 4G no internet. I called my provider they confirmed, as I had sim only contract, and by default 4G is not enabled for iphone X. They have different 4G settings for iPhone. Hope that helps.
My iPhone se displays 3g when I make a phone call instead of the 4g it still displays the lte but not the 4g and the carrier is cicket comparable to at&t

Cricket is NOT AT&T. They may use AT&T's network in some areas, but they are not AT&T. Contact Cricket and ask them.
Because it's not connected to an HSPA+ network.
How do I connect to a HSPAT+ network I’m cricket which is also AT&T.
And they would b able to give me the network information?
Since they are your carrier, they are the ONLY ones who can do so.
my iphone se doesnt displaye the 4g it displayes the 3g why?
