With the availability of different data plans on iPhone you now have the option to choose between them and thereby choose between varying data speeds. You have the freedom to set the maximum data speed that you wish for. This facility to switch between data speeds is available with iOS 8.1 though not yet on all network carriers. If your carrier does support this feature, then making use of it is extremely easy and useful.
Firstly, your iPhone must be running iOS 8.1 and also keep in mind that not every iPhone would contain this choice in the Settings app as it depends on the network carrier to let users change their data speed at will. Prior to trying this switch, you can try connecting your iPhone to a system with iTunes 12 or higher to check whether you get any carrier settings update that could enable this option. If your iPhone has the latest carrier settings, then you will receive a message informing you that your phone is already running on the latest software version. If this option doesn’t seem to be present, despite the above attempts then you can certainly contact your network provider and inquire about this feature.
Another important point to keep in your mind is that choosing the highest possible speed (LTE) will not always give you that cellular connection speed. This is because the connect cell tower may not support those high speeds and you may be pegged down to 3G from LTE or to 2G from 3G. This is dependent on your geographical location and connected cell tower’s capacity. The reverse process does not occur, i.e. choosing the 3G speed will never automatically cycle you up to LTE speed.
How to Change Cellular Data Speed on iPhone in iOS 8.x
Step #1. Tap the Settings app on your iPhone.

Step #3. Tap on Voice & Data option.
Step #4. Pick your desired cellular data speed from the following choices:
Step #5. Tap on Cellular once again and exit out of Settings to save the switched option.
- LTE gives you the highest data speed and is the quickest data service available, but adversely impacts your iPhone’s battery performance.
- 3G offers moderate speed cellular data transmission.
- 2G (Edge), comparatively quite slower cellular data and is at most times unusable for any major activity other than transferring miniscule amounts of text and data.
