Xiaomi Cannot Register on Telia Sweden

Xiaomi Cannot Register on Telia Sweden (2026 Fix)

If your Xiaomi, Redmi, or POCO phone shows "Not Registered on Network", only allows emergency calls, or fails to connect to Telia Sweden entirely, this guide covers common troubleshooting steps. This issue can occur across Sweden, from Stockholm and Gothenburg to Malmö, Uppsala, and Linköping, and may affect both 4G and 5G connections.

Before You Start – Quick Checks

  • Toggle Airplane Mode – Turn on for 30 seconds, then off to refresh network registration.
  • Restart your phone – Clears temporary software glitches that may prevent network registration.
  • Check Telia network status – Visit Telia's Driftinformation 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.

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 registration issue:

  • Does the phone show "Not Registered on Network"? – This error means your phone cannot complete the registration process with Telia's network.
  • Can you make emergency calls only? – If only emergency calls work, your phone is not properly registered with Telia's network.
  • Location-specific? – Does the issue occur everywhere or only in specific areas? This can indicate coverage gaps, network congestion, or regional network issues.
  • 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 Telia, 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.
  • Device compatibility – Some Xiaomi models, particularly imported China or India variants, may lack frequency bands required by Telia Sweden.
  • Network mode mismatch – If your phone is locked to a specific network mode (e.g., 5G only) in an area without coverage, it may fail to register.
  • Corrupted network settings – Network configurations can become corrupted and prevent registration.

Check Network Status (Telia Sweden)

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

  • Check Telia's Driftinformation page for planned maintenance or outages in your area.
  • Telia coverage maps show network availability across Sweden. Coverage is typically strongest in city centres like Stockholm, Gothenburg, and Malmö, but may be limited in rural areas.
  • If there is a confirmed outage, network registration may be restored automatically within a few hours.

Telia Network Notes (Sweden)

  • LTE (4G) bands: B3 (1800 MHz), B7 (2600 MHz), B20 (800 MHz). B20 is particularly important for rural and indoor coverage.
  • 5G NR bands: n78 (3500 MHz) – Primary 5G band in Sweden.
  • Legacy networks: GSM (900/1800 MHz) remains available for basic calls, but is being phased out. 3G/UMTS is being retired and should not be relied upon for primary connectivity.

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 Telia SIM into another phone (preferably a recent model, as older phones may not support Telia's current network configurations).
  • 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 – continue with the steps below.
  • If the SIM also fails on the other phone, the problem is likely with your SIM or account – contact Telia.

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

Step 2: Check Network Operator Selection

Why this matters: If manual network selection is configured incorrectly, the phone may fail to register on the selected network.

  • Settings → SIM cards & mobile networks
  • Tap your Telia SIM
  • Tap Network operators
  • Select Choose automatically (if currently set to manual)
  • Wait for the phone to register on Telia's network
  • Check if the "Not Registered on Network" error disappears

If the phone still cannot register, move to Step 3.

Step 3: Check Network Mode

Why this matters: If your phone is locked to a specific network mode (e.g., 5G only) in an area without coverage, it may fail to register.

  • Settings → SIM cards & mobile networks
  • Tap your Telia SIM
  • Tap Preferred network type
  • Select an automatic option like 5G/LTE/3G/2G Auto or 4G/LTE preferred
  • 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 4.

Step 4: Check Device Compatibility

Why this matters: Not all Xiaomi devices support all of Telia Sweden's frequency bands. This is particularly important for imported China or India variants.

Check your device model:

  • European/Global variants – Generally support Telia's bands, including B3 (1800 MHz), B7 (2600 MHz), and B20 (800 MHz).
  • China or India variants – May lack key LTE bands. For example, some imported variants may not support B20 (800 MHz), which is important for rural and indoor coverage.
  • Band 20 (800 MHz) is used by Telia for better coverage – If your device lacks B20, you may experience limited coverage in rural areas.

Important distinction:

  • No registration anywhere – This is more likely a SIM, account, or configuration issue, not a band compatibility issue.
  • Poor or limited coverage in some locations – This is more likely a band or coverage issue.

If your device is a European/Global variant and registration still fails, move to Step 5.

Step 5: Check SIM Toolkit (Secondary Diagnostic)

Why this matters: In some cases, the SIM Toolkit app may interfere with network registration. This is a secondary diagnostic step, not a primary cause.

  1. Open Settings → Apps
  2. Search for SIM Toolkit (or "Stk" or "SIS")
  3. Tap Force Stop
  4. Tap Storage → Clear cache and Clear data
  5. Restart your phone and check if registration works

If registration still fails, move to 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 Telia

If registration still fails, move to Step 7.

Step 7: Check for System Updates

Why this matters: Software updates often include modem firmware improvements that can resolve network registration issues.

  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 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 Telia's radio network. Only attempt this step if your phone can make calls but cannot access mobile data.

Standard Telia Sweden APN settings:

  • APN: online.telia.se
  • Username: (leave blank)
  • Password: (leave blank)
  1. Settings → SIM cards & mobile networks → Access Point Names
  2. Tap the menu icon (three dots) and select Reset to default
  3. If that doesn't work, manually create a new APN with online.telia.se
  4. Restart your phone and test data connectivity

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

Contact Carrier (When Required)

Contact Telia Sweden if:

  • Your SIM fails to register on other phones as well (SIM or account issue)
  • You've tried all steps above and registration still fails
  • You need a new SIM card
  • You need to check your account status

Telia Support (Sweden)

  • Call 90 222 from your Telia phone or 0771-90 222 from any phone
  • Telia Help Centre: telia.se/hjalp
  • Telia Driftinformation: telia.se/driftinformation
  • Telia App: Mitt Telia (available on Google Play Store)

Contact Xiaomi EU Support if:

  • You've tried all steps above and registration still fails
  • You've tested your SIM in another phone and it works normally
  • 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 Telia Sweden, start by testing your SIM in another phone – this is the quickest way to determine if the issue is your device or your SIM/account. If the SIM works elsewhere, check that your phone is set to automatic network selection and that the network mode is set to an automatic option like 5G/LTE/3G/2G Auto. Consider whether your device is an imported variant that may lack Telia's frequency bands, particularly B20 (800 MHz) for rural and indoor coverage – but note that band compatibility primarily affects coverage quality, not complete registration failure. If the issue persists, try restarting the SIM Toolkit app as a secondary diagnostic step, reset network settings, or check for system updates. APN configuration is relevant only after the phone has registered on the network – it does not cause registration failure. Contact Telia to verify your account and SIM provisioning if none of these steps resolve the problem.

Frequently Asked Questions

Why does my Xiaomi show "Not Registered on Network" on Telia Sweden?

This error is commonly caused by manual network selection misconfiguration, SIM/account issues, or device compatibility problems with Telia's frequency bands. In some cases, a stuck SIM Toolkit app may also be a factor.

What frequency bands does Telia Sweden use?

Telia Sweden uses LTE B3 (1800), B7 (2600), and B20 (800) for 4G. B20 (800 MHz) is particularly important for rural and indoor coverage. 5G is on n78 (3500 MHz).

Why does my Telia SIM work in another phone but not my Xiaomi?

This indicates a device-specific issue. It could be due to network mode settings, a stuck SIM Toolkit app, or device compatibility with Telia's frequency bands.

Why does my Xiaomi have signal but still show "Not Registered"?

Having signal bars means your phone can detect the network, but it cannot complete the registration process. This is usually due to manual network selection or a SIM/account issue.

Does Xiaomi work with Telia Sweden?

Most European/Global Xiaomi models work with Telia Sweden. However, imported China or India variants may lack frequency bands like B20 (800 MHz), which is important for rural and indoor coverage.

What APN settings does Telia Sweden use?

Telia Sweden uses APN online.telia.se with no username or password. APN only affects mobile data after registration, not the registration process itself.

Note: This guide is updated for 2026. Menu names may vary slightly between HyperOS and MIUI versions. Network registration issues can be caused by multiple factors; try the steps in order until the problem is resolved.
