OnePlus How to select preferred network type (2G/3G/4G)

The network mode or preferred network type is set by default to automatically search for 2G/3G/4G to achieve the best possible data connection and voice quality.

For example, if we have poor to moderate 4G reception area by area with the OnePlus smartphone, we can set the network mode ourselves to use the full width of the 3G network.

Note: If you experience reception problems during calls or phone calls, you can try setting the network mode to 2G to see if the problem is with network coverage.
