However, this could create issues where you have difficulty downloading data or making phone calls.
Additionally, being on an LTE network can indirectly cause you to use more data, simply because it downloads faster. if you are near your monthly data cap and are concerned about going over, then turning off LTE can help to reduce your data usage.
If you are no longer experiencing the issues that caused you to want to turn off LTE, then you can enable LTE on your iPhone by simply following these steps again and choosing the Voice and Data or Data Only option on the Enable LTE menu.
If your iPhone is using a lot of data after you updated to iOS 9, then you may want to look into a setting on your iPhone called Wi-Fi Assist. You can read here to learn how to turn off Wi-Fi Assist.
