Quick Navigation

Xiaomi Not Registered on EE UK? Quick Fix

  • ✔ Select network manually – Settings → SIM cards & mobile networks → Network operators → Turn off "Choose automatically" → Select EE.
  • ✔ Check IMS registration – Dial *#*#4636#*#* and check if IMS shows "Registered".
  • ✔ Enable VoLTE first – Settings → SIM cards & mobile networks → Your SIM → Enable "Use VoLTE" or "4G Calling".
  • ✔ Check Preferred Network Type – Try 4G (LTE) preferred instead of 5G.

Understanding "Not Registered on Network" vs "No Service"

These two messages mean different things:

  • "No Service" – Your phone cannot detect any cellular network at all. The signal bar is empty with a cross.
  • "Not Registered on Network" – Your phone can detect the network but cannot register on it for normal service. The signal bar shows a network name or "Emergency Calls Only".

This guide is for "Not Registered on Network" – the phone sees EE but can't connect properly.

Why Xiaomi Won't Register on EE UK

Understanding why this happens helps you fix it correctly:

Network Selection Issues

  • Automatic network selection fails – Xiaomi devices sometimes struggle to automatically select the correct EE UK network. Manually selecting the network often resolves this.
  • Dual-SIM conflicts – If you have two SIMs, the EE SIM may not register unless it's set as the primary data SIM or the other SIM is disabled.

EE 5G Standalone (SA) Compatibility

  • EE 5G SA device whitelist – Multiple EE community threads have reported that EE maintains a device whitelist for 5G Standalone (SA) access. Some Xiaomi devices may not be on the approved list and may show no service when trying to connect to 5G SA.
  • 5G SA can be forced – Some users have reported that forcing 5G SA using network tools like Network Signal Guru can work, but voice calls (VoNR) may not function, making the phone unusable for calls.

IMS Registration Issues

  • IMS not registered – IMS (IP Multimedia Subsystem) registration is required for VoLTE, VoWiFi, and proper network registration on modern UK networks. If IMS shows "Not Registered," your phone won't register fully on EE UK.
  • VoLTE disabled – EE UK requires VoLTE to be enabled for proper network registration on most Xiaomi devices.
  • Carrier profile mismatch – System updates can introduce carrier configuration mismatches that prevent network registration.

APN and Configuration Issues

  • APN misconfiguration – EE UK requires specific APN settings for data access. However, APN misconfiguration usually causes data issues, not network registration failure. Only try this step if you have signal but no data.

Hardware and IMEI Issues

  • Blocked IMEI – If the IMEI number is blocked (e.g., from a stolen phone or unpaid bills), the device won't register on any network.
  • SIM card damage – A damaged or faulty SIM can cause registration failures.

Why EE Specifically?

If your Xiaomi works on O2, Vodafone or Three but not on EE UK, the issue is often related to one of these factors:

  • EE's device certification list – EE maintains a list of approved devices for WiFi Calling and other network features. If your Xiaomi model isn't on the list, some services may not work.
  • EE's restrictive 5G SA whitelist – EE appears to restrict 5G SA access to certain devices. Even if your Xiaomi supports 5G SA, EE may not allow it to connect.
  • Carrier firmware requirements – EE has historically required specific firmware versions for features like VoLTE. Some users have reported needing to flash EE's EVR firmware to get full network functionality.
  • VoLTE dependency – EE relies heavily on VoLTE and IMS for network services. If VoLTE is disabled or IMS registration fails, the phone may show "Not Registered on Network".

Multiple EE community threads have reported that manually selecting the network and checking IMS registration are the two most effective fixes for this issue.

Step-by-Step Fixes

Step 1: Select Network Manually

Why this matters: Xiaomi devices can struggle to automatically select the correct EE UK network. Manually selecting the network forces the phone to register with EE UK directly.

  1. Settings → SIM cards & mobile networks
  2. Tap your EE SIM
  3. Tap Network operators or Choose network
  4. Turn off Choose automatically
  5. Wait for the phone to scan for networks
  6. Select EE (if you see multiple, try each)
  7. If the selection fails, try again after a few seconds

When this won't help: If you still see "Not Registered on Network" after manual selection, move to Step 2.

Step 2: Check IMS Registration Status

Why this matters: IMS registration is required for network registration on modern UK networks. If IMS shows "Not Registered," your phone won't fully register on EE UK.

  1. Open the Phone app
  2. Dial *#*#4636#*#* – note that this code may not work on all Xiaomi models
  3. Tap Phone information
  4. Look for IMS Service Status or IMS Registration
  5. It should show Registered. If it shows Not Registered, your phone can't register properly
  6. If IMS is not registered, try the VoWiFi carrier check code: dial *#*#869434#*#* and restart your phone

When this won't help: If IMS is already registered but you still can't register on EE, move to Step 3.

Step 3: Enable VoLTE (4G Calling) First

Why this matters: EE UK requires VoLTE to be enabled for proper network registration on most Xiaomi devices. Without VoLTE, the phone may not register on the network.

  • Settings → SIM cards & mobile networks
  • Tap your EE SIM
  • Look for "Use VoLTE" or "4G Calling"
  • Ensure it's toggled ON
  • Restart your phone and test

When this won't help: If VoLTE is already enabled or the option is greyed out, move to Step 4.

Step 4: Check Preferred Network Type

Why this matters: If your phone is set to 5G only, it may struggle to register in areas with poor 5G coverage. Additionally, EE's 5G Standalone (SA) network may not be supported on all Xiaomi devices.

  • Settings → SIM cards & mobile networks
  • Tap your EE SIM
  • Tap Preferred network type
  • Select 4G (LTE) preferred or 5G/LTE/3G/2G Auto
  • Restart your phone and test

5G SA note: If your Xiaomi supports 5G SA but shows no service, EE may be blocking it. Try using 4G LTE instead for reliable service. See the EE 5G SA Workaround below.

When this won't help: If you're in a strong 5G area and other 5G devices work, move to Step 5.

Step 5: Reset APN Settings

Why this matters: Incorrect APN settings can prevent data access. EE UK requires specific APN settings for data access. However, APN misconfiguration usually causes data issues, not network registration failure. Only try this step if you have signal but no data.

  1. Settings → SIM cards & mobile networks
  2. Tap your EE SIM
  3. Tap Access Point Names (APN)
  4. Tap the menu icon (three dots) and select Reset to default
  5. If you see "No APN configured," create a new APN with the settings below

EE UK APN Settings

Note: APN settings can vary by plan. The settings below are for EE's default consumer APN. Most consumer SIMs use no username/password. The eesecure/secure settings are for older or business accounts.

SettingValue
NameEE
APNeverywhere
UsernameLeave blank (or eesecure for business accounts)
PasswordLeave blank (or secure for business accounts)
MMSChttp://mms/
MMS Proxy149.254.201.135
MMS Port8080
MCC234
MNC30
Authentication TypePAP
APN typedefault,supl,mms
APN protocolIPv4/IPv6

Save the APN, select it, restart your phone, and test.

When this won't help: If APN settings are correct but registration still fails, move to Step 6.

Step 6: Clear SIM Toolkit Cache

Why this matters: Corrupted SIM Toolkit data can interfere with network registration.

  1. Settings → Apps → Manage apps
  2. Find SIM Toolkit or Stk
  3. Tap Clear data and Clear cache
  4. Restart your phone and test

When this won't help: If clearing the SIM Toolkit cache doesn't help, move to Step 7.

Step 7: Check IMEI Status

Why this matters: If your IMEI is blocked, the phone won't register on any network. This can happen with stolen devices or phones with unpaid bills.

  • Open the Phone app
  • Dial *#06#
  • Check that both IMEI numbers appear correctly
  • If IMEI shows as "Unknown" or "0", the phone has a software or hardware issue
  • If IMEI appears but you suspect it's blocked, contact EE UK to check

When this won't help: If IMEI is valid and shows correctly, move to Step 8.

Step 8: Reset Network Settings

Why this matters: This resets Wi-Fi, mobile data, and Bluetooth settings without deleting your personal data. It clears any corrupted network configurations that may be blocking registration.

  1. Settings → Connection & sharing (on HyperOS) or Settings → Additional settings → Backup & reset (on MIUI)
  2. Select Reset Wi-Fi, mobile & Bluetooth or Reset network settings
  3. Confirm the reset
  4. Restart your phone
  5. Reconnect to your mobile network

When this won't help: If resetting network settings doesn't work, move to Step 9.

Step 9: Check for HyperOS Updates

Why this matters: Software updates often include bug fixes and improvements that can address connectivity issues.

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

When this won't help: If you're already on the latest version, move to Step 10.

Step 10: Test SIM in Another Phone

Why this matters: This helps identify if the issue is your phone or your SIM/carrier.

  • Insert your EE SIM into another phone
  • If it works, the issue is with your Xiaomi device
  • If it doesn't work, the issue is with your SIM or carrier

EE 5G SA Workaround

If your Xiaomi supports 5G Standalone (SA) but shows no service on EE, this is likely a carrier whitelist restriction. Try these options:

  • Switch to 4G preferred – Settings → SIM → Preferred network type → 4G (LTE) preferred. This bypasses the 5G SA issue entirely.
  • Contact EE – Ask EE if your Xiaomi device is on their 5G SA approved list. If not, they may be able to add it.
  • Advanced users only – Apps like Network Signal Guru can force 5G SA. However, voice calls (VoNR) may not work, which can make the phone unusable for calls.

When to Contact EE UK or Xiaomi UK Support

Contact EE UK if:

  • The SIM works in another phone but not yours
  • You've tried all steps above and still can't register
  • You suspect your IMEI is blocked
  • There's a known network issue in your area
  • You need a SIM replacement
  • You believe your Xiaomi should support 5G SA but it's not connecting
  • Your account is inactive or unpaid

Contact Xiaomi UK Support if:

  • You've tried all steps above and still can't register
  • You've tested your SIM in another phone and it works
  • The issue persists across multiple SIM cards
  • You suspect a hardware fault with the cellular antenna or modem chip
  • IMEI shows as Unknown

  • EE UK Support: Call 150 from your EE phone or 07953 966 250 from any phone | EE Help Centre
  • Xiaomi UK Support: Xiaomi UK Support Portal
  • Feedback app: Settings → Services & feedback

Final Verdict

If your Xiaomi won't register on EE UK, the most common cause is incorrect network selection, IMS registration failure, or EE's 5G SA whitelist restrictions. Start by manually selecting EE UK in Network operators, then check IMS registration using *#*#4636#*#*. If IMS shows "Not Registered," enable VoLTE and try the VoWiFi carrier check code *#*#869434#*#*.

If you're trying to connect to 5G SA and your Xiaomi supports it but shows no service, EE may be blocking it. Use 4G LTE preferred for reliable service.

Quick summary:

  • "Not Registered on Network" → Select network manually; check IMS registration
  • Signal but no data → Reset APN settings; check APN type
  • No signal at all → Re-seat SIM; test in another phone; check IMEI
  • Dual SIM issues → Set EE SIM as primary; remove second SIM temporarily
  • 5G SA not connecting → Switch to 4G preferred; check EE device whitelist

Frequently Asked Questions

Why does my Xiaomi say "Not Registered on Network" on EE UK?

This usually means the phone can detect the network but cannot register on it for normal service. Common causes include: incorrect network selection, IMS registration failure, VoLTE disabled, or a blocked IMEI.

How do I manually select EE UK on Xiaomi?

Go to Settings → SIM cards & mobile networks → Tap your SIM → Network operators → Turn off "Choose automatically" → Select EE.

What is IMS registration on Xiaomi?

IMS (IP Multimedia Subsystem) registration is required for VoLTE, VoWiFi, and proper network registration on modern UK networks. Dial *#*#4636#*#* and check IMS Service Status – it should show "Registered".

Does EE UK work on imported Xiaomi phones?

Yes, but you may need to manually configure APN settings and network selection. Some EE services like 5G SA may not work on imported devices due to EE's whitelist.

Can a factory reset fix "Not Registered on Network"?

Factory reset can help if the issue is caused by corrupted system files or network profiles. However, it should be used as a last resort. Before trying a factory reset, try the steps in this guide first.

Does replacing the SIM card fix this?

Yes, if the issue is caused by a damaged or faulty SIM card. If you've tried all steps and your SIM works in another phone but not yours, the issue is with your Xiaomi device.

Why does my Xiaomi work on other networks but not EE?

EE uses a different network configuration and may have stricter device certification requirements. EE's 5G SA whitelist is a notable example. Also, EE relies heavily on VoLTE and IMS for network services.

Does EE support 5G SA on Xiaomi?

EE has a device whitelist for 5G SA. Some Xiaomi devices may not be on the approved list, even if they technically support 5G SA. This is a carrier restriction, not a device issue. Multiple EE community threads have reported this limitation.

Do these fixes work on UK Xiaomi devices?

Yes. This guide applies to Xiaomi, Redmi, and POCO devices sold in the UK. The steps are identical across UK models.

Xiaomi Equalizer Settings: Best Sound for Headphones & Earbuds (UK 2026)

How to Boost Headphone Bass on Xiaomi Phones (MIUI Guide for UK Users) Music is closely tied to emotions, and for many UK users, headphones are a constant companion throughout the day—whether commuting in London , relaxing in a Manchester flat, or catching up on podcasts in Birmingham . Naturally, everyone wants the best possible sound quality from their Xiaomi device, without relying on third-party apps that take up storage space. Why Bass Matters Before boosting headphone bass, it’s worth understanding the basics. Humans can hear frequencies from 20Hz to 20kHz. The lower end, below 250Hz, represents bass sounds. Within this range, the lowest frequencies contribute to deep bass, while slightly higher frequencies provide “punchy” bass. MIUI’s equaliser allows you to tweak these frequencies, regardless of the headphone model—be it Mi AirDots , Redmi AirDots S, or higher-end wired headphones. Setting up the equaliser properly is crucial for achieving the richest sound experience...
