How to Change Network Mode on Xiaomi Phone (2G/3G/4G/5G Switch)
Changing network mode helps save battery, improve signal, or fix connectivity issues in specific areas.
Steps to Change Network Mode
On HyperOS:
1. Settings → SIM cards & mobile networks.
2. Tap the SIM you want to change.
3. Tap Preferred network type.
4. Choose your desired mode.
On MIUI 14 / 13:
1. Settings → SIM cards & mobile networks → [SIM name].
2. Tap Preferred network type.
Network Mode Options Explained
| Mode | Best Use Case |
|---|---|
| 5G/4G/3G/2G (Auto) | Default — phone chooses best available |
| 5G | Maximum speed; higher battery drain |
| 4G/3G/2G (Auto) | Good balance; use if no 5G SIM |
| LTE only | Force 4G; prevents drop to 3G/2G |
| 3G/2G | Very low signal areas; saving battery |
| 2G only | Extreme battery saving; calls/SMS only |
When to Use Each Mode
- Traveling abroad → set to 4G/3G/Auto to match local carrier.
- Battery dying fast → set to 3G or 2G to reduce radio power.
- Poor signal at home → try 4G only instead of Auto to prevent constant network switching.
- VoLTE calls cutting out → keep on 4G LTE mode.
Shortcut via Dialer (Hidden Menu)
On some Xiaomi models, you can access network settings faster:
1. Open the Phone app → Dial `*#*#4636#*#*`.
2. Tap Phone information.
3. Select Set Preferred Network Type from the dropdown.
Note: This shortcut may not work on all HyperOS builds.
Pro Tips
- Changing to 2G only is the most effective way to extend battery life in an emergency.
- In areas with 5G mmWave coverage, keeping 5G Auto on uses noticeably more battery than 4G-only.
- After a SIM swap or carrier change, always reset network mode to Auto to let the phone detect the best available signal.
