Net 4.5 G in Android 9 pie ?

[SL2121]

With the update to Android 9 foot to use the mobile data no longer appears the function of 4.5 G now only appears 4G. With the update the phone stopped being compatible?

Or is the function still there only that it is no longer visible?

If anyone knows what happened because in Android 8.0 I had the 4.5 G phone, I would appreciate it if you could explain

Well... it Depends witch telephone network you have. To me appears a plus simbol on the side of 4G
