iPhone users doesn’t have to ability to choose their desired maximum cellular data speed until the iOS 8.1 update. The option to switch between 2G, 3G or LTE mobile data vanished when Apple updated the iOS 7 to iOS 8. But with the October update of iOS 8.1 address the major annoyance for users in some countries where there is still a poor 3G of 4G LTE connection coverage.
The option to switch between mobile data networks also allows the iPhone user to extend the battery life of their devices. As mentioned before, users must be on iOS 8.1, and not all iPhones are going to have this option available within the Settings app. It will depend on cellular carriers to allow its users to toggle between the data speed.
- Switch between the 2G, 3G or 4G LTE Data Speed on iPhone or iPad
- Open the Settings app on the iPhone and go to “Cellular” or “Mobile”.
- Now tap on the Cellular or Mobile Data.
- Switch the Enable LTE toggle OFF to disable LTE data.
- Tap back onto Cellular, and exit out of Settings to apply the changes.
Note that switching OFF LTE will also disable the 3G , and you will be surfing on the 2G data. While for some carriers allows to switch between 2G, 3G or LTE by giving an extra option under the Cellular Data.
Users may want to connect your iPhone to a computer with iTunes 12 (or newer) before trying this to see if there is a carrier settings update available through iTunes that could enable it. If all else fails, you could always contact your cell plan provider directly and ask about the feature too.
Remember, whatever you choose is the maximum speed, which not necessarily a guarantee that your iPhone will always use that chosen cellular connection speed. Meaning, if you choose LTE, the mobile network may still cycle down to 3G or 2G, as the connected cell tower may only support those speeds. Though, on the other hand, choosing something like 3G might scale you down to 2G but will never scale up to LTE.
