Does turning off VoLTE also disable Wi-Fi Calling?

No, VoLTE and Wi-Fi Calling are separate settings. VoLTE controls calls over the mobile 4G network, while Wi-Fi Calling routes calls through your Wi-Fi connection. You can find and adjust Wi-Fi Calling separately if your carrier supports it.

What happens to a call if I have weak 4G coverage with VoLTE enabled?

If the 4G signal drops during a call, the phone typically falls back to 2G or 3G automatically to keep the call connected. Once you move back into 4G coverage, new calls will use VoLTE again as long as the setting under Enable or disable VoLTE Calls stays switched on.

Will enabling VoLTE change my data usage?

VoLTE affects how voice calls are routed, not general data browsing. Call setup becomes slightly faster and audio quality improves, but this does not meaningfully increase your monthly data usage.

Can I use VoLTE while roaming on Realme?

That depends entirely on whether your carrier has activated VoLTE roaming agreements with the network abroad. If not supported, calls will automatically use the older 2G or 3G network even with the VoLTE Calls toggle enabled.

Realme: Turn VoLTE Calls On or Off

If your Realme phone still connects calls over the 2G or 3G network, call setup feels slower and voice quality suffers. VoLTE routes voice calls through the 4G network instead, but only works when it is switched on for the SIM card you are actually using. On dual-SIM devices each SIM has its own VoLTE toggle, which is why one line can sound noticeably better than the other.

Turn On/Off VoLTE Calls auf Realme

By default, a Realme phone can fall back to the 2G or 3G network for voice calls, even if you have a strong 4G signal for data. That fallback is what causes slower call setup and weaker audio quality. VoLTE (Voice over LTE) keeps the call on the 4G network instead, which shortens connection time and improves clarity.

On Realme UI, VoLTE is controlled per SIM card, not for the whole device. This matters on dual-SIM phones: you can enable VoLTE for one SIM and leave it off for the other, so only one line benefits while the second still uses the older network for calls.

To check or change the setting, go to Settings ➔ SIM card & mobile data ➔ choose the SIM card you want to adjust ➔ then enable or disable VoLTE Calls for that SIM.

Turning VoLTE on also tends to lower battery drain during calls, since the phone does not need to switch radio modes between data and voice. If your carrier does not support VoLTE on that SIM, the toggle may have no visible effect even when switched on. Turn VoLTE off only if you have a specific reason, such as troubleshooting a call issue with your carrier.

Frequently asked questions

VoLTE depends on carrier support for that specific SIM. If the toggle is missing or grayed out for the second SIM, that carrier likely has not enabled VoLTE on the account, even though the setting path under SIM card & mobile data is the same for both SIMs.
