To enable VoLTE on your iPhone 11, open Settings > Cellular > Cellular Data Options > Enable LTE, then choose Voice & Data. This turns on Voice over LTE, which gives you clearer calls, faster call setup, and the ability to use data while you talk, plus access to the call's volume, mute and speaker controls without dropping your connection.
How to enable VoLTE on iPhone 11
- Open Settings.
- Tap Cellular (or Mobile Data in some regions).
- Tap Cellular Data Options (or Mobile Data Options).
- Tap Enable LTE.
- Select Voice & Data.
If your carrier supports VoLTE, you will see three choices: Off, Voice & Data, and Data Only. Voice & Data allows both voice calls and cellular data over LTE. Data Only lets data use LTE but keeps voice calls on older networks. Off turns LTE off entirely. On some carriers or in certain regions, the menu may appear as Mobile Data > Mobile Data Options > Voice & Data instead of the Cellular path.
What if you don't see the VoLTE option?
If Voice & Data or VoLTE does not appear, the most likely reason is that your carrier does not support VoLTE on your line or in your region. Apple states that the available options depend on the carrier, and if VoLTE is unsupported, the iPhone may show LTE/4G, 3G, or 2G options instead. On CDMA networks without VoLTE support, you may only see Enable LTE, which means LTE is used for data only. If the carrier is CDMA and does not support VoLTE, Apple says you may only see Enable LTE. On some carriers like AT&T, VoLTE is enabled by default on newer iPhone models, so the absence of a toggle does not mean VoLTE is unavailable, it may already be active. AT&T's iPhone 11 support page says on most newer models, VoLTE is enabled by default, so you may not see a separate VoLTE switch. Update Carrier Settings via Settings > General > About to address VoLTE-related issues. Reset Network Settings via Settings > General > Reset > Reset Network Settings to resolve persistent VoLTE connectivity problems.
Which iPhones and carriers support VoLTE?
Apple officially states that VoLTE is available on iPhone 6 or later, which includes the iPhone 11. However, Apple's iPhone 11 specifications note that Gigabit-class LTE, VoLTE, and Wi-Fi calling are available in select markets and through select carriers. Availability depends on both the carrier and the region, so you must confirm that your specific carrier and plan support VoLTE on your device. Carrier feature pages only confirm that VoLTE is available on iPhone 6 or later, with availability varying by country and carrier. To check carrier compatibility, visit your carrier's official website and navigate to the support or FAQ section for VoLTE compatibility and supported devices lists. To check carrier compatibility, contact your carrier's customer support by phone or in-store to verify if VoLTE is enabled for your account.
