Xiaomi VoLTE Not Working on ice Norway

Xiaomi VoLTE Not Working on ice Norway (2026 Fix)

If your Xiaomi, Redmi, or POCO phone drops to 2G/3G during calls, shows "Can't use VoLTE", or the VoLTE option is missing or greyed out on ice Norway, this guide covers common troubleshooting steps. Even if your phone is connected to a 5G network for data, voice calls may still rely on VoLTE (4G) or fallback to older networks, depending on your device and network configuration.

Before You Start – Quick Checks

  • Check your device compatibility – ice requires phone manufacturers to prepare their models for 4G-Tale (VoLTE). Older or imported phones may not support the service.
  • Make sure the phone can connect to ice's 4G network in your location – VoLTE requires a 4G signal.
  • Toggle Airplane Mode – Turn on for 30 seconds, then off to refresh network registration.
  • Restart your phone – Clears temporary software glitches affecting IMS registration.

If these quick checks don't work, continue with the step-by-step guide below.

Quick Navigation

Diagnose the Issue First

Before making changes, determine the pattern of your VoLTE issue:

  • Is the option missing entirely? – The VoLTE toggle does not appear in your SIM settings.
  • Is the option visible but calls drop to 2G/3G? – The toggle is on, but during calls the network indicator changes from 4G/5G to 2G/3G. On ice, when 4G-Tale is active, you should see an ice+ or VoLTE symbol.
  • Does the phone have signal but no VoLTE? – The phone may still show 4G, but calls may not use VoLTE. ice states that when 4G-Tale is available, a "VoLTE symbol" should appear at the top of the screen.
  • When did the issue start? – If it began after a system update, the problem may be software-related. If it started after a SIM swap or traveling, network provisioning or carrier configuration might be the cause.

Why This Happens

  • Device compatibility with ice – ice requires that phone manufacturers prepare specific models for 4G-Tale. If your Xiaomi model is not on ice's compatibility list, VoLTE may not work.
  • IMS registration failure – VoLTE requires IMS (IP Multimedia Subsystem) registration. If IMS is not registered, VoLTE won't work. ice uses Mavenir's cloud-native IMS solution for VoLTE and 5G voice.
  • Xiaomi carrier check – Xiaomi's VoLTE carrier check may block the feature, even when the network supports it. The Xiaomi carrier check code can be used to toggle this, but it does not add compatibility to an unsupported phone.
  • Software or configuration issues – Incorrect network settings or outdated system software can prevent VoLTE from working.
  • Regional ROM variations – Some Xiaomi devices running regional or China-market firmware may have different carrier feature support, so VoLTE availability can differ even when the hardware supports it.

Quick Diagnostic Table

  • VoLTE option missing → Device compatibility, carrier provisioning, Xiaomi carrier check, or ROM variant
  • Option visible but not working → IMS registration, network coverage, or software configuration
  • Works on other phones but not on Xiaomi → Xiaomi-specific carrier check or device compatibility
  • VoLTE works temporarily but turns off after reboot → Possible registration, carrier-configuration, or device software issue

Check ice 4G-Tale Support

Before troubleshooting your device, verify that your ice plan and phone are compatible:

  • ice 4G-Tale (VoLTE) – ice's 4G-Tale service (also known as VoLTE) allows you to make calls over the 4G network. It provides HD voice, faster call setup, and the ability to surf while on a call.
  • Device compatibility list – ice maintains a list of phones that support 4G-Tale. If your Xiaomi model is not on the list, it may not support the service.
  • ice's network – ice has upgraded to Mavenir's end-to-end cloud-native IMS solution, enabling VoLTE and 5G voice (VoNR). The service is activated free of charge for subscriptions with a compatible phone.
  • ice's 2G shutdown context: ice is participating in Norway's 2G network phase-out, making 4G-Tale and VoLTE increasingly important for voice calls.

Important: Carrier Check

  • If your Xiaomi model is not on ice's compatibility list, VoLTE may not work even if you enable it in settings.
  • Contact ice directly to confirm whether your specific device model is supported for 4G-Tale.

Check Your Exact Xiaomi Model

Why this matters: Different Xiaomi models and regional variants can have vastly different support for carrier features like VoLTE. Simply knowing you have a "Xiaomi" is not enough.

  • Find your exact model number – Go to Settings → About phone and note the Model and MIUI/HyperOS version.
  • Check the region/ROM – The software version often indicates the region (e.g., Global, EEA, China, India).
  • Compare with ice's compatibility list – Check ice's official support page to see if your specific model is listed.
  • If your device is not on the list, it may still work, but this reduces the likelihood that VoLTE will function correctly.

Test SIM in Another Phone

Why this matters: This is the quickest way to determine if the issue is your Xiaomi device or your SIM/plan.

  • Insert your ice SIM into another phone that supports VoLTE
  • Check if VoLTE works on the other phone (look for 4G/LTE indicator during a call or a VoLTE symbol)
  • If VoLTE works normally on the other phone, the issue is more likely related to your Xiaomi device or its configuration – continue with the steps below
  • If VoLTE also doesn't work on the other phone, the problem is more likely related to your SIM, plan, or carrier provisioning – contact ice

Step 1: Enable VoLTE in Settings

Why this matters: If your Xiaomi exposes a VoLTE or 4G Calling setting, it must be enabled.

  • Settings → SIM cards & mobile networks
  • Tap your ice SIM
  • Look for VoLTE, Use VoLTE, or 4G Calling and toggle it ON

If the option is not visible:

  • Your Xiaomi model may not support VoLTE on ice, or the VoLTE carrier check may be blocking it.
  • Try the hidden diagnostic code in Step 2.

If the option is enabled but VoLTE still doesn't work, move to Step 2.

Step 2: Check VoLTE with the Hidden Xiaomi Code

Why this matters: Xiaomi devices have a hidden diagnostic code that can toggle the VoLTE carrier check. ice's official support documentation recommends this code for Xiaomi phones from 2017-2019: *#*#86583#*#*. In some cases, this check blocks VoLTE even when the network supports it.

  1. Open the Phone app
  2. Dial *#*#86583#*#*
  3. If supported, the phone may display a message indicating that the VoLTE carrier check has been disabled.
  4. This may enable the VoLTE option if it was previously hidden.
  5. Restart your phone and check if VoLTE works

Important: This code toggles the carrier check on and off. Dialing it again will re-enable the check. The code may not work on all Xiaomi devices or HyperOS versions. It does not add ice support to an incompatible phone or provision VoLTE on your account.

If VoLTE still doesn't work, move to Step 3.

Step 3: Check IMS Registration Status (If Available)

Why this matters: VoLTE requires IMS registration. The IMS status can reveal whether the phone is successfully registered for VoLTE on ice's network. ice uses Mavenir's IMS solution, which supports VoLTE and 5G voice.

If your Xiaomi exposes the Android testing/IMS status menu:

  1. Open the Phone app
  2. Dial *#*#4636#*#*
  3. Select Phone information
  4. Tap the three dots in the top right corner
  5. Select IMS Service Status (if available)
  6. If IMS information is exposed, look for the VoLTE/IMS registration status.

If IMS shows "Not available" or "Not registered":

  • Try toggling Airplane Mode on and off to re-register
  • Try toggling VoLTE off and on in Settings while on LTE
  • If IMS registration fails consistently, carrier provisioning becomes one of the things to check.

Note: The exact menu and available IMS information vary by model and HyperOS/MIUI version. This menu is not available on every Xiaomi device. If the menu is not available, proceed to Step 4.

If IMS registration fails, move to Step 4.

Step 4: Reset Network Settings

Why this matters: This resets Wi-Fi, mobile data, and Bluetooth settings without deleting personal data. It can clear problematic network configurations that may be preventing IMS registration.

  1. Settings → Connection & sharing (HyperOS) or Settings → Additional settings → Backup & reset (MIUI)
  2. Select Reset Wi-Fi, mobile & Bluetooth or Reset network settings
  3. Confirm the reset
  4. Restart your phone
  5. Wait a few minutes for the phone to reconnect to the network
  6. Re-enable VoLTE in Settings
  7. Check if VoLTE works (look for 4G/LTE indicator or ice+ symbol during a call)

If VoLTE still doesn't work, move to Step 5.

Step 5: Check for System Updates

Why this matters: Software updates can include modem, carrier-configuration, or connectivity fixes that may affect VoLTE. ice recommends keeping your phone's software updated for 4G-Tale.

  1. Settings → About phone → Check for updates
  2. Install any available updates
  3. Restart your phone and check if VoLTE works

If you're already on the latest version and VoLTE still doesn't work, contact ice or Xiaomi support.

Decision Box – What to Do Next?

Still not working? Let's narrow it down:

  • ✓ SIM has no VoLTE in another phone? → Contact ice (plan or provisioning issue).
  • ✓ SIM works elsewhere but not on your Xiaomi? → Device-specific issue (continue troubleshooting above).
  • ✓ VoLTE option is missing? → Check device compatibility with ice, try the hidden diagnostic toggle (Step 2), or check if your device is an imported variant.
  • ✓ VoLTE turns off after reboot? → Toggle Airplane mode once after reboot. If VoLTE returns, this points to a registration/configuration issue that may need further investigation.
  • ✓ Nothing works? → Contact ice to check account provisioning and device compatibility.

Contact Carrier (When Required)

Contact ice Norway if:

  • Your SIM has no VoLTE in other phones as well (plan or provisioning issue).
  • You've tried all steps above and VoLTE still doesn't work.
  • You need to verify that your plan includes 4G-Tale.
  • You need to check whether your Xiaomi model is on ice's 4G-Tale compatibility list.

ice Support (Norway)

Contact Xiaomi Support if:

  • You've tried all steps above and VoLTE still doesn't work.
  • You've tested your SIM in another phone and it works normally.
  • Your device is a European/Global variant but VoLTE still fails.
  • You suspect a software or hardware issue with your device.

Xiaomi Support

Final Verdict

If your Xiaomi won't use VoLTE on ice Norway, follow this diagnostic flow:

  1. Check device compatibility – ice requires phones to be prepared for 4G-Tale. Check if your Xiaomi model is on ice's compatibility list.
  2. Check your exact model and ROM variant – Compatibility can vary by region and firmware.
  3. Check 4G coverage – VoLTE requires a 4G signal. Ensure you are in an area with ice's 4G network coverage.
  4. Test SIM in another phone – This isolates carrier vs. device issues.
  5. Enable VoLTE in Settings – Go to SIM settings and enable VoLTE.
  6. Try the Xiaomi diagnostic code – *#*#86583#*#* toggles the VoLTE carrier check on supported devices. It does not add compatibility to an unsupported phone.
  7. Check IMS status if available – *#*#4636#*#* can help diagnose registration.
  8. Reset network settings – As a last-resort device configuration step.
  9. Check for system updates – May contain modem or carrier fixes.

If none of these steps resolve the problem, contact ice to verify your account provisioning and device compatibility.
