Take direct command of your cellular radio
5G VoNR Network Mode is a free Android utility that puts manual network selection back in your hands. Instead of relying on the manufacturer’s default or hidden automatic settings, this app lets you choose the radio mode that best matches your coverage and battery preferences so you can tailor connectivity to your needs.
Available radio modes you can force
- GSM Only — keep your device on legacy 2G networks when that’s the most reliable option.
- WCDMA Only — lock to 3G for more stable voice/data in areas where 4G/5G is unreliable.
- LTE Only (4G) — force use of 4G for consistent data throughput and broad compatibility.
- NR Only (5G Only) — connect exclusively to 5G cells where available to test speed or latency improvements.
How Voice over New Radio (VoNR) improves calls
Voice over New Radio (VoNR) is the native 5G voice technology that can deliver clearer audio and quicker call setup compared with older voice methods that rely on 4G/3G fallbacks. When your device and network both support VoNR, you may notice reduced call connection delay and better overall voice fidelity.
Compatibility, caveats, and safety notes
Not every handset will permit forced switching between radio modes. Several manufacturers and carriers restrict changes for stability or regulatory reasons, and some functions may require root access or specific firmware. If the app cannot impose a selected mode on your phone, it’s usually due to these built-in locks. Use caution when changing modes: forcing an incompatible setting can disrupt voice/data service or reduce battery efficiency.
A suggested substitute app
If you’re exploring alternatives, consider OmeTV (free) as a different kind of mobile communication app. It isn’t a network-mode tool, but it provides a free platform for voice/video chats if your goal is to test or use real-time voice services over whatever connection you have.
