If you’ve bought a new 5G smartphone, particularly one of the latest iPhone models, you might’ve noticed that it sometimes switches between 4G and 5G automatically. That’s because iOS 17 shifts between the networks based on different factors, such as your phone’s needs and battery life, by default. Nonetheless, sometimes we want our iPhones to persistently stick to 4G or 5G instead of hopping between the two. Fortunately, you can control that. Whether you have an iPhone 15 Pro Max or an older model, you can follow the steps below to stop your device from switching between 4G and 5G automatically. However, if you’re running earlier versions of iOS, you may see “LTE” or “4G” used in place of each other.
