While most subscribers are moving to 5G network, the 4G network remain as one of the network that support most subscribers, be it local or even data roamers.
Lately, B38 is detected as a third component in 4G+ networks. It combines B3, B7 and B38 to form a 3 CA network. With 15 MHz of B38, it greatly boost the download speed.
If you use a Samsung smartphone, you will be able to check that with *#0011#. It is not known if B38 is enabled at all nodes but it is defintely a band that is largely under utilised. If your phone supports 3 CA or more, it will definitely benefit in the downlink speed.
