Xiaomi Cannot Register on ice Norway

Xiaomi Cannot Register on ice Norway: 2026 Troubleshooting Guide

If your Xiaomi, Redmi, or POCO phone shows "Not Registered on Network", only allows emergency calls, or fails to connect to ice Norway entirely, this guide covers common troubleshooting steps. VoLTE primarily matters when the phone registers but voice service fails; it is not a universal explanation for failure to register on the network.

First, determine which scenario applies to you:

  • A. Cannot register on ice at all – No signal, or "Not Registered on Network" with no service.
  • B. Registers, but cannot make calls – Mobile data works, but calls fail or drop to 2G/3G.
  • C. Registers, but mobile data doesn't work – Calls work, but no internet access.

This guide will help you diagnose each scenario.

Before You Start – Quick Checks

  • Check ice network status – Visit ice's Driftstatus page for any outages in your area.
  • Test your SIM in another phone – This is the quickest way to determine if the issue is your Xiaomi device or your SIM/account.
  • Test another SIM in your Xiaomi – This helps identify if the problem is with your Xiaomi device or the ice SIM/account.
  • If your Xiaomi has mobile data but cannot make calls – Check VoLTE compatibility first.
  • If ice is visible but registration fails – Test SIM + verify device compatibility.
  • If another SIM also fails on your Xiaomi – Investigate device-specific issues.

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 network issue:

  • Does the phone show "Not Registered on Network"? – This error means your phone cannot complete the registration process with ice's network.
  • Can you make emergency calls only? – This usually means the phone is not normally registered on its home/selected mobile network.
  • Do you see signal bars but can't register? – Signal bars only mean your phone detects a radio signal. Registration and authentication with ice's network are separate processes.
  • Does the problem occur everywhere or only in specific areas? – Network performance can vary across Norway. Check ice's coverage map for your exact location.
  • Did it work before? – Did this issue start after a system update, SIM swap, or traveling abroad?

Why This Happens

  • Network operator selection issue – If your phone is set to manual network selection and cannot find ice, it may fail to register.
  • Device compatibility – Some Xiaomi models or regional variants may have compatibility issues with ice's current network configuration.
  • Network mode mismatch – If your phone is locked to a specific network mode in an area without coverage, it may fail to register.
  • SIM or account issues – Your SIM card may be faulty, not properly provisioned, or your account may have an issue.
  • 2G shutdown – Norway's 2G shutdown can affect phones that rely on 2G for voice service, particularly when 4G/VoLTE voice is unavailable.

Quick Diagnostic Table

  • No signal / no networks found → Coverage, network mode, radio/band compatibility, SIM/device configuration, or hardware
  • ice visible but registration fails – Seeing ice means the phone can detect the network, but it does not prove that the device is authorized or compatible for registration. This may indicate a SIM/account provisioning issue, authorization problem, or device compatibility/configuration issue. This has been reported with some Xiaomi models.
  • Registered but no mobile data → APN/data provisioning
  • Calls work but 5G doesn't → 5G provisioning/compatibility
  • SIM fails in every phone → SIM/account/carrier

Check Network Status (ice Norway)

Before troubleshooting your device, verify ice's network status:

  • Check ice's Driftstatus page for coverage and any planned maintenance or outages in your area.
  • Network change: ice has migrated to the Telenor network, and some Xiaomi/device combinations have been reported to have compatibility issues following network changes.
  • 2G network status: 2G has been shut down in many areas. Check with ice for the current 2G status in your area.
  • If ice reports an outage affecting your area, wait until the network issue is resolved before continuing with device troubleshooting.

ice Network Notes (Norway)

  • Network operator: ice Norway (formerly Ice.net).
  • Network migration: ice has migrated to the Telenor network, which has been associated with compatibility issues for some devices.
  • 2G network: 2G has been shut down in many areas. Do not rely on 2G as a fallback.
  • VoLTE/4G voice requirement: With the 2G shutdown, phones that do not support 4G/VoLTE may not be able to make calls on ice's network.

Step 1: 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/account.

  • Insert your ice SIM into another phone (preferably a recent model that supports 4G/VoLTE).
  • Check if the phone registers on the network and can make calls.
  • If the SIM works normally on the other phone, the issue is likely with your Xiaomi device or its configuration – continue with the steps below.
  • If the SIM also fails on the other phone, the problem is likely with your SIM or account – contact ice.

If the SIM works normally in another phone, continue with Step 2.

Step 2: Test Another SIM in Your Xiaomi

Why this matters: This helps isolate whether the problem is with your Xiaomi device or with the ice SIM/account.

  • Insert a working SIM from another carrier into your Xiaomi.
  • Check if the phone registers on the network with the other SIM.
  • If another SIM works on your Xiaomi, the problem is more likely specific to the ice SIM, ice account/provisioning, or compatibility/configuration between the Xiaomi and ice.
  • If another SIM also fails on your Xiaomi, the problem is more likely with your Xiaomi device itself.

If both SIMs fail on your Xiaomi, continue with Step 3.

Step 3: Check Network Operator Selection

Why this matters: If manual network selection is configured incorrectly, the phone may fail to register on the selected network. This step also helps you determine whether ice is visible.

  • Settings → SIM cards & mobile networks
  • Tap your ice SIM
  • Tap Network operators
  • First, try automatic selection: Select Choose automatically (if currently set to manual). Wait for the phone to register on ice's network.
  • If automatic selection fails: Tap Search networks and wait for the list of available networks.

Interpret the result:

  • If ice is not visible in the list – The phone cannot detect the network. This may indicate a coverage, radio compatibility, or hardware issue.
  • If ice is visible but registration fails – Seeing ice means the phone can detect the network, but it does not prove that the device is authorized or compatible for registration. This may indicate a SIM/account provisioning issue, authorization problem, or device compatibility/configuration issue.

If automatic selection fails, move to Step 4.

Step 4: Check Network Mode

Why this matters: If your phone is locked to a specific network mode in an area without coverage, it may fail to register. 2G has been shut down in many areas, so do not rely on 2G as a fallback.

  • Settings → SIM cards & mobile networks
  • Tap your ice SIM
  • Tap Preferred network type
  • Select the highest automatic network mode available, preferably one that includes 4G/LTE and 5G. Do not force 5G only.
  • Wait 30 seconds and check if the phone registers

Note: If the phone registers on 4G but not 5G, the issue is likely 5G-specific. You can continue using 4G while troubleshooting 5G separately.

If registration still fails, move to Step 5.

Step 5: Check IMEI and Baseband

Why this matters: This is a critical diagnostic step that is often overlooked in generic guides. A missing or unknown IMEI or baseband indicates a more serious modem or hardware issue that cannot be fixed by changing APN or network settings.

  1. Open the Phone app
  2. Dial *#06#
  3. Check if an IMEI number is displayed
  4. If IMEI is missing, null, or unknown, the phone has a device-level problem that may involve the modem, firmware, or hardware.
  5. To check baseband: Settings → About phone and look for Baseband version. If it shows "Unknown" or is missing, this also indicates a device-level issue.

If IMEI or baseband is missing/unknown:

  • This points to a device-level modem, firmware, or software problem and requires further diagnosis.
  • Contact Xiaomi support for further assistance.
  • Do not attempt to fix this with network resets or APN changes.

If IMEI and baseband are present, continue with Step 6.

Step 6: Reset Network Settings

Why this matters: This resets Wi-Fi, mobile data, and Bluetooth settings without deleting personal data. It clears corrupted network configurations that may be preventing 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. Give the phone a few minutes to reconnect to the network
  6. Check if the phone registers on ice

Note: You will need to reconnect to saved Wi-Fi networks after performing this reset.

If registration still fails, move to Step 7.

Step 7: Check for System Updates

Why this matters: A pending system update may contain modem or carrier-configuration fixes, so updating is worth checking if the problem started after a software change.

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

If you're already on the latest version and registration still fails, move to Step 8.

Step 8: Check VoLTE (If Registered but Calls Fail)

Why this matters: This step is specifically for Scenario B: the phone registers on the network, but you cannot make calls.

If mobile data works but voice calls fail, VoLTE/4G voice compatibility is one of the most likely issues.

  • Check if your Xiaomi model supports VoLTE on ice – Some Xiaomi models have been reported to have 4G voice/VoLTE compatibility problems on ice. The Xiaomi Mi 10 Pro is one example reported by a customer.
  • Try the VoLTE carrier-check toggle – For some Xiaomi phones, dialing *#*#86583#*#* may change the device's VoLTE carrier-check behavior. This code does not add VoLTE hardware or network compatibility; on supported models, it may only change the device's VoLTE carrier-check behavior.
  • Contact ice to verify compatibility – If VoLTE is not working, contact ice to confirm whether your specific Xiaomi model is supported on their current network.

If calls still don't work, move to Step 9.

Step 9: Check APN (Only if Data Fails After Registration)

Why this matters: APN settings affect mobile data connectivity after the phone has registered on the network. They normally do not determine whether the phone can register on ice's radio network. Only attempt this step if your phone can make calls but cannot access mobile data.

Do not change APN settings while the phone is not registered on the network.

ice Norway APN settings: Use the APN currently supplied automatically by your SIM. Only manually configure it if mobile data is not working after registration. For current official APN settings, check ice's support pages.

  1. Settings → SIM cards & mobile networks → Access Point Names
  2. Tap the menu icon (three dots) and select Reset to default
  3. Restart your phone and test data connectivity

Important: Some Xiaomi devices may not allow saving APNs with certain MNC settings, reverting to a different value instead. If you experience this, leave MNC as automatically provided by the device.

If registration still fails or data is still not working, contact ice or Xiaomi support.

Decision Box – What to Do Next?

Still not working? Let's narrow it down:

  • ✓ ice SIM fails in another phone? → Contact ice (SIM or account issue)
  • ✓ ice SIM works elsewhere, but fails on Xiaomi? → Device-specific issue (continue troubleshooting above)
  • ✓ Another SIM also fails on Xiaomi? → Xiaomi-specific issue (check IMEI/baseband, reset, update)
  • ✓ ice network is visible but registration fails? → The phone can detect the network, so investigate SIM/account provisioning, device compatibility, or network-side authorization – contact ice
  • ✓ Xiaomi registers but mobile data doesn't work? → Check APN settings (Step 9)
  • ✓ Your Xiaomi has mobile data but cannot make calls? → Check VoLTE/4G voice compatibility (Step 8) – this has been reported as an issue on ice with some Xiaomi models.

Contact Carrier (When Required)

Contact ice Norway if:

  • Your SIM fails to register on other phones as well (SIM or account issue)
  • ice is visible but registration is denied (authorization/provisioning issue)
  • You've tried all steps above and registration still fails
  • You need a new SIM card
  • You need to check your account status
  • You need to confirm whether your Xiaomi model is compatible with ice's current network configuration

ice Support (Norway)

  • Call 21 00 00 00
  • Customer service: +47 97 77 75 94
  • ice Help Centre: ice.no/kundeservice/
  • ice App: ice (available on Google Play Store)
  • Email: app@ice.net

Contact Xiaomi Support if:

  • You've tried all steps above and registration still fails
  • Other SIMs also fail on your Xiaomi
  • IMEI or baseband is missing/unknown
  • Your device is a European/Global variant but network registration fails
  • You suspect a hardware fault with the cellular antenna or modem

Final Verdict

If your Xiaomi cannot register on ice Norway, follow this diagnostic hierarchy:

  1. Test your SIM in another phone – to isolate SIM/account issues.
  2. Test another SIM in your Xiaomi – to isolate device issues.
  3. Check network selection – automatic mode first, then manual search to see if ice is visible.
  4. Check network mode – ensure a mode that includes 5G and 4G/LTE is selected (2G is shut down in many areas).
  5. Check IMEI and baseband – if missing, this points to a device-level modem, firmware, or software problem and requires further diagnosis.
  6. Reset network settings – clears corrupted configurations.
  7. Check for system updates – may contain modem fixes.
  8. Check VoLTE – only if the phone registers but cannot make calls.
  9. Check APN – only if the phone is registered but mobile data doesn't work.

Important note for ice users: ice has migrated to the Telenor network, and 2G is shut down in many areas. If your Xiaomi does not support 4G/VoLTE, it may no longer work on ice's network. Contact ice to verify compatibility or consider upgrading to a newer device that supports 4G voice.
