Different generations of network technology, such as 3G, 4G, and 5G, have varying properties and coverage areas. In some cases, a phone may prioritize connecting to a weaker signal on a newer network just for the sake of displaying a "5G" status. This can result in weaker connections. Toggling between different available network modes can help, especially for Verizon customers. On iPhones, network modes can be adjusted under Cellular Data Options, while Android phones have them under Connections or SIM & Network settings.
