换ROM试试吧

For APN, you can check:
1/ check if you save new lte APN (most people forget it)
2/ Go to other places where LTE signal is strong

If not working for above, u can try install the app "LTE OnOFF" to your phone.
- after installation, force to lte. Open the app > select "LTE only". See if you can have LTE signal.
If OK, then change back to " LTE/GSM/WCDMA"

This checks your rom is OK for receiving LTE signal...

If all are not working, flash back to official stock rom

网络模式有没有选lte啊  没有你在弄apn都是白搭
