Answer 2

Answer:

A mobile phone, through supports a 4G service, is receiving only 3G. "There should be two possible reasons.

Explanation:

• First of all, following the phase,” there is not a problem in the plant, the main problem should be in the root.”. Here the root is the Sim card, if the Sim card does not support 4G, then a phone has nothing to do.
• There is one solution for this, the user should change/upgrade his Sim card. Alternatively, every phone has a feature to set the Sim card default value to 4G/3G, but the user would not know about that. He should open the phones setting and change the preferred data speed to 4G."
