Xiaomi Cannot Register on Telekom Germany

Xiaomi Cannot Register on Telekom Germany – Fix

If your Xiaomi, Redmi, or POCO device cannot register on the Telekom network in Germany, this guide explains why and how to fix it.

Quick Answer:
Xiaomi phones usually fail to register on Telekom Germany because of SIM activation issues, incorrect network selection, unsupported regional firmware, or carrier provisioning problems. Restart the phone, toggle Airplane mode, check your SIM activation, and manually select Telekom before contacting support.

Why Telekom May Reject Registration

Several factors can prevent your Xiaomi from registering on Telekom Germany's network:

  • SIM not activated – New or replacement SIMs may not be activated yet.
  • Wrong network selection – Manual network selection may be set to a different carrier.
  • Temporary network glitch – Your phone may have failed to register after losing signal.
  • Regional firmware limitations – Regional firmware may not include the carrier configuration or modem customisations required for some European carriers. A user with a Redmi K80 (Chinese version) reported being unable to connect to 5G on Telekom due to firmware limitations.
  • 5G SA compatibility issues – Some users have reported registration or connectivity issues after enabling Telekom's 5G Standalone (5G+) service on certain Xiaomi models. Switching temporarily to LTE can help determine whether 5G SA is the cause.
  • Account issues – Suspended account, unpaid bills, or provisioning errors.
  • Missing IMS provisioning – Some MVNOs using the Telekom network (like Lebara) may not provide complete carrier profiles for Xiaomi devices, causing registration issues.

Check Whether Telekom Can See Your Device

Before troubleshooting your phone, check if there's a network issue in your area:

  • Check Telekom's coverage map at telekom.de/netz.
  • Check if Telekom has reported any network outages or maintenance in your area.
  • Ask someone nearby using Telekom whether they have signal.

If another Telekom customer nearby also has no signal, the issue is likely network-related.

Check Your SIM

If you've just received a new SIM or switched to Telekom, the SIM may not be activated yet:

  • New SIMs can take up to a few hours to activate.
  • If you ported your number, activation may take longer.
  • Contact Telekom to confirm your SIM is active.

Quick Fixes to Test First

Try these quick actions in order. Check if the network registration issue resolves after each step.

1. Toggle Airplane Mode

Switching Airplane mode on and off forces your phone to disconnect and reconnect to nearby towers.

  1. Swipe down to open Quick Settings.
  2. Enable Airplane mode.
  3. Wait 30 seconds.
  4. Disable Airplane mode.
  5. Wait up to 2 minutes for network registration.

2. Restart Your Xiaomi

Restarting refreshes network registration and clears temporary software glitches.

  1. Hold the Power button.
  2. Select Restart.
  3. Wait for the phone to fully boot.
  4. Wait 2 minutes for network registration.

3. Reinsert Your SIM

SIM cards can become loose or dirty.

  1. Power off your phone.
  2. Remove the SIM card.
  3. Check for dirt or scratches on the gold contacts.
  4. Gently clean with a soft cloth if dirty.
  5. Reinsert the SIM firmly.
  6. Power on and wait 2 minutes.

4. Test Your SIM in Another Phone

This quick test helps determine whether the issue is with your Xiaomi or your Telekom SIM:

  • Insert your Telekom SIM into another phone.
  • If the other phone registers on the network, the issue is likely with your Xiaomi.
  • If the other phone also fails to register, the issue is likely with your Telekom account, SIM, or network coverage.

Check Network Selection Settings

If your phone is trying to connect to the wrong carrier, manually selecting Telekom can resolve the issue.

  1. Settings → SIM cards & mobile networks → [Telekom] SIM.
  2. Tap Network operators or Mobile networks.
  3. Turn off Select automatically.
  4. Wait for available networks to appear.
  5. Select Telekom.de or Telekom Germany from the list.
  6. Once connected, re-enable Select automatically if you prefer.

Check 5G+ (5G Standalone) Settings

Some users have reported registration or connectivity issues after enabling Telekom's 5G Standalone (5G+) service on certain Xiaomi models. Switching temporarily to LTE can help determine whether 5G SA is the cause.

  1. Settings → SIM cards & mobile networks → [Telekom] SIM.
  2. Tap Preferred network type.
  3. Try switching between options (e.g., 5G/4G/3G/2G auto, 4G only).
  4. If 5G causes issues, select 4G (LTE) only temporarily.
  5. Wait 30 seconds after each change.

Imported Xiaomi Devices on German Networks

Xiaomi devices not intended for the European market may have network registration issues on Telekom Germany. A user with a Redmi K80 (Chinese version) reported being unable to connect to 5G on Telekom despite the device supporting all required bands.

Possible reasons:

  • China ROMs may lack carrier configuration for German networks.
  • Some imported devices may not support 5G NSA, which is more common in Europe.
  • Regional firmware may restrict certain network features.

What to check:

  • European ROMs (Global/EEA) typically include settings for German carriers.
  • If you've tried all the steps above and your imported Xiaomi still doesn't register, device compatibility may be the underlying issue.

If You're Using an MVNO on Telekom's Network

Some MVNOs using the Telekom network (such as Lebara) may not provide complete carrier profiles for Xiaomi devices, causing registration issues.

What to try:

  • Insert the SIM into a non-Xiaomi phone (Samsung, iPhone, Pixel) and leave it connected to the network for several minutes to allow IMS provisioning.
  • Move the SIM back to your Xiaomi and restart.
  • If the issue persists, contact your MVNO provider.

Why Can I See Telekom but Can't Register?

If Telekom appears in the available networks list but your phone can't register, possible reasons include:

  • Your SIM is not activated or is suspended.
  • Your account has billing or provisioning issues.
  • Carrier restrictions (e.g., plan not compatible with your device).
  • Unsupported firmware or regional ROM.

Check IMEI Status

A missing or invalid IMEI can prevent network registration.

  1. Open the dialler and enter *#06#.
  2. Verify that a valid IMEI number appears.
  3. If no IMEI appears, or it shows Null or Unknown, this usually indicates a hardware or firmware issue and may require professional repair.

Check for System Updates

Ensure your device is running the latest software version:

  1. Settings → About phone → Check for updates.
  2. Install any available updates.
  3. Restart your phone.

Reset Network Settings (Last Resort)

If nothing else works, reset network settings. This removes saved Wi-Fi passwords and Bluetooth pairings, and resets all mobile network settings.

  1. Settings → Additional settings → Backup & reset → Reset phone → Reset network settings.
  2. Confirm the reset.
  3. Restart your phone.
  4. Note: You'll need to reconnect to Wi-Fi networks afterwards.

If Mobile Data Still Doesn't Work After Registration

APN settings only affect mobile data after your phone has successfully registered on the network. If your phone connects to Telekom but mobile data doesn't work.

Contact Telekom

Contact Telekom if:

  • Network registration issues persist after completing all steps above.
  • Your SIM works fine in another phone but not in your Xiaomi.
  • You suspect a network provisioning issue with your account.
  • Your SIM may not be activated yet.

What to ask Telekom: Ask Telekom to verify that your SIM is correctly provisioned for voice, SMS and network services, confirm your SIM is activated, and check whether there are any local network issues in your area.

How to contact Telekom:

  • Call Telekom customer service
  • Visit a Telekom store
  • Use the MeinMagenta app

Final Verdict

If your Xiaomi still cannot register after checking the SIM, network selection, and software compatibility, the issue is commonly related to your Telekom account provisioning, SIM status, or device firmware compatibility. Telekom support can verify whether your SIM is correctly provisioned and confirm if your device is fully supported on the network. APN settings only affect mobile data after registration—if your phone registers but data doesn't work, check the APN separately.

Frequently Asked Questions

Do APN settings affect network registration?
No. APN settings only affect mobile data after your phone has successfully registered on the network.

Why does my Xiaomi say "Not registered on network" on Telekom?

Why can I see Telekom but can't register?
If Telekom appears in the available networks list but your phone can't register, possible reasons include: SIM not activated, account suspension, carrier restrictions, or unsupported firmware.
