Xiaomi Stuck on Emergency Calls Only in the UK

Quick Answer:
If your Xiaomi is stuck on "Emergency Calls Only," first toggle Airplane mode on/off for 30 seconds, then restart. If that doesn't work, go to Settings → SIM cards & mobile networks → [Your carrier] SIM → Network operators → Search networks → Select your carrier manually. These steps resolve most cases.

Applies to Redmi, POCO and Xiaomi Phones

This guide applies to Xiaomi, Redmi and POCO devices running MIUI or HyperOS, covering UK carriers including EE, O2, Vodafone, Three, Giffgaff, SMARTY, and others.

What Does "Emergency Calls Only" Mean?

"Emergency Calls Only" means your phone can see a mobile network but cannot register for standard service. This is different from "No Service" (no network detected at all).

🔍 Decision Gate – Find Your Path

Use this decision flow. Do not skip steps:

CheckIf YesIf No
Is the SIM detected? (Settings → About phone → SIM status)Continue to next checkReinsert SIM → restart → if still not detected, Section 2
Is the IMEI visible? (*#*#4636#*#* → Phone information → IMEI)Continue to next checkSTOP: Baseband/modem issue – Section 5
Is there signal? (signal bars visible)Continue to next checkManual network selection → Section 3
Does the phone show "Emergency Calls Only"?GO TO Section 1No issue – your phone is working

Section 1 – Temporary Network Registration Failure (Highest Priority)

If your SIM is detected, IMEI is visible, signal is present, but "Emergency Calls Only" appears, the issue is almost always network registration failure. This is the most common scenario (~70% of cases).

Try these in strict order:

  1. Toggle Airplane mode – ON for 30 seconds, then OFF. This forces the phone to restart the registration process.
  2. Restart your phone – A full reboot often clears temporary network registration glitches.
  3. Manual network selection – Settings → SIM cards & mobile networks → [Your carrier] SIM → Network operators → Turn off "Choose automatically" → Search → Select your carrier manually.
  4. Check preferred network type – Settings → SIM cards & mobile networks → [Your carrier] SIM → Preferred network type → If set to 5G only in a weak 5G area, switch to 4G/3G/2G auto.

Decision: If Section 1 fails → proceed to Section 2.

Section 2 – SIM, Account, or Provisioning Issue

If Section 1 fails, the issue is likely with the SIM profile, carrier provisioning, or account status. The priority order is:

  • Priority 1 – Network attach failure (SIM not attaching to the network): Test your SIM in another phone. If it also fails, proceed below.
  • Priority 2 – SIM provisioning: Your carrier may not have provisioned the SIM correctly for standard service.
  • Priority 3 – Account issue: Unpaid bill, expired PAYG credit, or suspended account.

Try these in order:

  1. Test your SIM in another phone – If it works there, the problem is your Xiaomi → go to Section 4. If it also shows "Emergency Calls Only" there, continue below.
  2. Call your carrier – EE (150), O2 (202), Vodafone (191), Three (333). Ask: "Is my account active? Is there any bar on my SIM? Can you send a fresh SIM profile?"
  3. Request a new SIM profile – Over-the-air (OTA) refresh.
  4. If all else fails: Request a replacement SIM – older SIMs may lack modern provisioning profiles.

Section 3 – No Signal / Network Not Visible

If your phone shows no signal at all, the issue is network visibility – not registration.

  1. Manual network selection – Settings → SIM cards & mobile networks → [Your carrier] SIM → Network operators → Turn off "Choose automatically" → Search → Select your carrier manually.
  2. Check preferred network type – Switch to 4G/3G/2G auto.
  3. Check for carrier outage – Ask others nearby or check your carrier's status page.
  4. If still no signal: Proceed to Section 4.

Section 4 – Device-Specific Issues (Layered Approach)

If your SIM works in another phone but not in yours, the problem is your Xiaomi. The causes are layered:

  • Layer 1 – UI/Region layer (easiest to fix): Region setting, system language, or carrier visibility.
    • Check region: Settings → Additional settings → Region → set to United Kingdom.
    • Clear Phone app cache: Settings → Apps → Manage apps → Phone → Storage → Clear cache.
  • Layer 2 – System layer: System app restrictions or background services.
    • Boot into Safe Mode: Press and hold Power → long-press Restart → tap Safe Mode. If signal returns, a third-party app is interfering.
    • Check SIM Activation Service permissions: Settings → Apps → Manage apps → search for "SIM Activation Service" → Permissions → ensure SMS is allowed.
    • Reset network settings: Settings → Connection & sharing → Reset Wi-Fi, mobile networks, and Bluetooth (last resort).
  • Layer 3 – Modem layer (rare): Baseband/modem firmware issue. Proceed to Section 5.

Section 5 – IMEI Missing or Baseband Issue (Stop Condition)

If the IMEI number is missing (shows "Unknown" or "Null") in *#*#4636#*#*, this is a critical hardware/firmware issue. Do not continue with standard troubleshooting.

Diagnostic decision:

  • Stop: This is not a settings issue. Standard fixes will not work.
  • Try restarting your phone – sometimes the modem fails to load on boot. If IMEI returns, proceed back to Section 1.
  • Check for system updates – Settings → About phone → System update – a newer version may restore the modem.
  • If IMEI is still missing: This requires reflashing the modem firmware or restoring the device via Mi Flash Tool. This is an advanced step – contact Xiaomi support or a technician.
  • Check if your IMEI is blocked: Call your carrier and ask if your IMEI is blacklisted (lost/stolen). If it is, the phone will never register.

⚠️ What NOT to Do

  • Don't factory reset as a first step – network registration issues are rarely solved by a factory reset.
  • Don't assume the phone is broken – test your SIM in another phone first.
  • Don't ignore carrier account status – if your account is suspended, no setting will help.
  • Don't skip the IMEI check – if IMEI is missing, standard fixes will not work.

Quick Questions

What's the difference between "Emergency Calls Only" and "No Service"?
"Emergency Calls Only" means your phone can see a network but can't register for service. "No Service" means your phone can't find any network at all.

Why does my phone show Emergency Calls Only after a HyperOS update?
Updates can reset network settings or preferred network type. Try manual network selection (Section 1) or reset network settings.

Will resetting network settings delete my photos?
No. Only saved Wi-Fi passwords and Bluetooth pairings are removed.

How do I know if the problem is my phone or my carrier?
Test your SIM in another phone. If it works there, the problem is your Xiaomi. If it also shows Emergency Calls Only, the problem is your SIM or carrier account.

What if my IMEI is missing?
This is a serious baseband/modem issue. This is a stop condition – standard troubleshooting will not work. Contact Xiaomi support or a technician.

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...
