This guide explains how to manually select whether your iPhone uses 4G or 5G for mobile data. This can be useful if you want to save battery life, improve connection stability, or ensure higher speeds in certain areas.
Why choosing 4G or 5G matters
Your mobile network selection affects:
- Data speeds
- Battery usage
- Connection stability
In some locations, 4G may be more stable, while 5G can offer higher speeds where coverage is strong.
What you need
- An iPhone that supports 4G and/or 5G
- An updated version of iOS
- Active mobile data
Step 1: Open Settings
- Open Settings on your iPhone.
- Tap Mobile Service (or Cellular).
Step 2: Go to mobile data options
- Tap Mobile Data Options.
- Select Voice & Data.
Step 3: Choose 4G or 5G
You will see one or more of the following options (depending on your iPhone model and iOS version):
- 5G Auto – Uses 5G only when it won’t significantly reduce battery life.
- 5G On – Always uses 5G when available.
- 4G (LTE) – Uses 4G only.
Choose the option that best fits your needs.
Summary
By following these steps, you can manually control whether your iPhone uses 4G or 5G for mobile data.
