VoLTE Check: Enable 4G Calling

VoLTE not working, or the VoLTE option not showing in settings? Check VoLTE in one tap: see if your phone, SIM and operator support VoLTE (4G LTE calling with HD voice, also called HD calling), and find out exactly what to fix.

VoLTE Check runs a full check of your phone, SIM, network and settings. When something blocks VoLTE, it says so plainly, like "Airplane mode is on", "4G turned off" or "VoLTE is turned off", and one button opens the right setting. Change it, come back, and it shows as fixed.

✅ Full VoLTE check
• Does my phone support VoLTE?
• Does my operator allow VoLTE on this SIM? Each SIM checked on dual-SIM phones
• Is VoLTE enabled in settings?
• Is the network mode set to 2G/3G only, or to 4G only?
• Airplane mode, mobile data, roaming and SIM lock checked too

🛠️ Enable VoLTE and fix what's wrong
• Each VoLTE problem in plain words, the most important first
• One tap to the right settings screen
• How to turn VoLTE on or off on Samsung, Xiaomi, Redmi, POCO, OnePlus, Realme, Vivo, iQOO, Oppo and Motorola, plus Pixel and other stock Android phones
• Opens the hidden phone info screen (*#*#4636#*#*) on phones that have it, and says when your phone has it locked

💬 Your calls, explained
VoLTE Check notes the network each call used: VoLTE, VoNR (5G calling), Wi-Fi calling (VoWiFi) or 2G/3G. Rate your calls and it tells you what they mean, like "VoLTE works", "Weak-signal calls" or "Calls never use 4G" with the reason, and what to do next.

📈 VoLTE Watch: one short report a week
Your phone notes its network every 30 minutes. Once a week you get a short report: how much of the week was on 5G, 4G or 3G, when it dropped, and one fix. The readings stay on your phone.

📨 Ask your operator, in one tap
When only your operator can turn VoLTE on, VoLTE Check writes the request for you, ready to send.

📡 Looking for "Force LTE only" or "4G LTE only mode"?
Android does not let a normal app lock your phone to a network mode, not this app and not the apps that say they do. VoLTE Check opens the network mode settings where that choice lives and tells you which options are safe. It warns when the network mode is set to 2G/3G only, or to 4G only, which leaves calls with nothing to fall back to.

📶 What is VoLTE?
VoLTE (Voice over LTE) carries calls over 4G LTE instead of older 2G/3G networks: faster call setup, HD voice, and mobile data that keeps working during calls.

❓ VoLTE questions

How do I enable VoLTE on Android?
Open your mobile network settings and turn on VoLTE, which may be called VoLTE calls, 4G calling, HD calls or Enhanced 4G LTE mode. VoLTE Check opens the right screen for you.

VoLTE option not showing on Samsung, Vivo or Redmi?
Usually your operator has not enabled VoLTE for your SIM, or your phone's software does not include it. VoLTE Check shows which of the two it is.

Phone shows 4G, but calls go to 3G or H+?
Data can run on 4G LTE while calls fall back to 2G/3G when VoLTE is not active. Check whether your operator allows VoLTE on your SIM.

How do I turn off VoLTE?
Switch it off in the same mobile network settings. Calls then use 3G or 2G where your operator still has them; on 4G-only networks, calls need VoLTE.

What is VoNR (5G calling)?
Voice over New Radio, the 5G version of VoLTE. VoLTE Check shows when a call used it.

🌍 Works with operators worldwide
Works with Jio, Airtel, Vi, BSNL and VoLTE operators around the world, on most Android phones from Android 6. Not affiliated with any operator.

🔒 Private by design
No account and no location permission. Every check runs on your phone and nothing is uploaded. Phone access is used only to read your operator's VoLTE setting, your SIM slots and the network a call used. It never reads your phone number, contacts or messages.

ℹ️ Honest about limits
On most phones Android does not let apps read live IMS registration. Where it won't say, VoLTE Check says "Not sure" instead of guessing. VoLTE also depends on your operator, your SIM plan and your region.
