Although public Wi-Fi networks are readily available in most places, there are times when people need to use mobile data. Often, we may not get a strong enough signal on a 4G or 5G network. You can get around this problem by manually switching your phone to a 2G or 3G bandwidth.
Android users can do this by entering “Network Settings,” then “SIM Card Settings,” followed by tapping “Preferred Network Type” and choosing the desired option. iPhone users will be able to change their bandwidth settings by going to “Settings” and then “Mobile Data,” followed by “Mobile Data Options” and “Voice & Data.”
