Xiaomi Stuck on Emergency Calls Only in the UK

Xiaomi Stuck on "Emergency Calls Only" in the UK – Fix

If your Xiaomi, Redmi, or POCO device shows "Emergency Calls Only" and won't connect to your UK network for calls, texts, or mobile data, this guide explains why and how to fix it.

Quick Answer:
"Emergency Calls Only" means your Xiaomi can't register on your carrier's network. This is usually caused by temporary network glitches, SIM issues, weak signal, or incorrect network settings. Start by toggling Airplane mode, restarting your phone, and reinserting your SIM. Only check network settings or contact your carrier if basic steps don't work.

What "Emergency Calls Only" Means

When your Xiaomi displays "Emergency Calls Only," your phone cannot establish a proper connection with your mobile network provider. Your device still allows emergency calls because emergency systems remain accessible even when standard network registration fails.

This is different from having a weak signal. Even with signal bars, the phone may still fail to register on the network.

When this problem appears, you may notice:

  • No normal phone calls
  • Mobile data not working
  • SMS messages failing to send
  • Signal disappearing completely
  • SIM card errors

Why This Happens

  • Temporary network glitch – Your phone may have failed to register with the network after losing signal.
  • Weak mobile network coverage – Poor signal inside buildings, underground, or in remote areas.
  • SIM card problems – Damaged, loose, or dirty SIM contacts.
  • Wrong network configuration – Incorrect preferred network type or manual network selection.
  • Software bugs – After a HyperOS or system update.
  • Hardware problems – Broken SIM slot or damaged antenna.

Check Network Status – UK Carrier

Before troubleshooting your phone, check if the issue is network-wide.

  • EE – Check coverage at ee.co.uk/coverage or call 150.
  • O2 – Check coverage at o2.co.uk/coverage or call 202.
  • Vodafone – Check coverage at vodafone.co.uk/coverage or call 191.
  • Three – Check coverage at three.co.uk/coverage or call 333.
  • Giffgaff – Check network status at giffgaff.com/network-status.
  • SMARTY – Check coverage at smarty.co.uk/coverage.

If outages are reported in your area, wait for your carrier to resolve the issue.

Quick Fixes to Test First

Try these quick actions in order. Check if the "Emergency Calls Only" message disappears 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. Check IMEI

A missing or invalid IMEI can prevent network registration.

  1. Open the dialler and enter *#06#.
  2. Check if an IMEI number appears.
  3. If no IMEI appears, or it shows Null or Unknown, the phone may be unable to register on mobile networks. This usually requires professional repair or manufacturer support.

Check Signal Strength

Weak signal is a common cause of network registration failure.

  1. Settings → About phone → Status → SIM status → Signal strength.
  2. Good: -50 to -80 dBm. Should register.
  3. Weak: -100 to -120 dBm. May fail to register.

If signal is weak, try moving to a different location or near a window.

Test Your SIM

First test: Insert your SIM into another phone. If the other phone registers on the network, the issue is device-related. If both phones show "Emergency Calls Only," the issue is network coverage or your account.

Second test: Insert another working SIM into your Xiaomi. If the other SIM registers on your phone, your original SIM may be faulty. Contact your carrier for a replacement.

If neither SIM works in your Xiaomi, the issue is more likely to be with the phone than the SIM card.

Check Network Selection Settings

Your phone may have been set to a different network operator.

  1. Settings → SIM cards & mobile networks → [Your carrier] SIM.
  2. Tap Network operators or Network selection.
  3. Ensure Select automatically is enabled.
  4. If not, turn it on and wait for registration.

If You Recently Travelled Abroad

If the issue started after travelling abroad, your phone may still be trying to connect to a foreign network. Make sure Automatic network selection is enabled (see the section above).

Check Preferred Network Type

Sometimes the wrong preferred network type can cause registration failure.

  1. Settings → SIM cards & mobile networks → [Your carrier] SIM.
  2. Tap Preferred network type.
  3. Try switching between options (e.g., 4G only, 5G recommended, 3G).
  4. Wait 30 seconds after each change.

Note: Some Xiaomi models hide this option. If unavailable, check Settings → Mobile networks.

Check for PIN Lock

If your SIM is PIN-locked and you haven't entered the PIN after restarting, your phone may show "Emergency Calls Only."

  1. Check if your phone is asking for the SIM PIN.
  2. Enter your SIM PIN if prompted.
  3. If you've entered the wrong PIN multiple times, you may need the PUK code. Contact your carrier to unlock the SIM.

Update HyperOS / MIUI

Software bugs can sometimes break network registration after updates.

  • Settings → About phone → Check for updates. Install any available updates.
  • If the issue started after a recent update, restart your phone again.

Advanced / Rare: Check Fixed Dialling Numbers (FDN)

Some Vodafone UK users have reported this issue when Fixed Dialling Numbers (FDN) is enabled. This is a very rare cause and should only be checked if other steps don't resolve the issue.

Check and disable FDN if needed:

  1. Open the Phone app.
  2. Tap the menu icon (three dots).
  3. Settings → Calling accounts → Advanced settings.
  4. Tap Fixed dialling numbers.
  5. Select your SIM.
  6. Toggle the switch to turn FDN OFF.

Note: The default PIN2 is 1111. If you've changed your PIN2, use that instead.

Reset Network Settings (Last Resort)

If nothing else works, reset network settings. This removes saved WiFi passwords and Bluetooth pairings.

  1. Settings → Additional settings → Backup & reset → Reset phone → Reset network settings.
  2. Confirm the reset.
  3. Restart your phone.
  4. Wait 2 minutes for network registration.

Contact Your Carrier

Contact your carrier if:

  • The issue persists 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 has been blocked or needs a PUK code.

UK carrier contact numbers:

  • EE: 150
  • O2: 202
  • Vodafone: 191
  • Three: 333
  • Giffgaff: 0330 123 0002
  • SMARTY: 0333 202 0033

Final Verdict

"Emergency Calls Only" on your Xiaomi is usually a temporary network glitch, SIM issue, or signal problem. Start by toggling Airplane mode, restarting your phone, and reinserting your SIM. Check IMEI and signal strength. Test your SIM in another phone and try another SIM in your Xiaomi. Ensure automatic network selection is enabled. Only check FDN or reset network settings if basic steps don't resolve the issue. If all fails, contact your carrier to check your account and local network coverage.

Frequently Asked Questions

What does "Emergency Calls Only" mean on my Xiaomi?
It means your phone cannot register on your carrier's network. You can only make emergency calls until the issue is resolved.

Why does my Xiaomi say Emergency Calls Only after restarting?
Your phone may take 1–2 minutes to register on the network after restarting. Wait 2 minutes before troubleshooting. If it persists, try toggling Airplane mode.

Why does Emergency Calls Only appear after a HyperOS update?
HyperOS updates can occasionally reset network preferences or affect modem behaviour. Try restarting your phone, toggling Airplane mode, and checking network selection settings. If the problem started immediately after a HyperOS update and other troubleshooting doesn't help, check for another system update over the next few days or contact Xiaomi Support.

Can eSIM cause Emergency Calls Only?
Yes. eSIM profiles can sometimes fail to activate or become corrupted. Try restarting your phone. Removing and re-adding the eSIM profile may help, but only if your carrier recommends it.

Does Fixed Dialling Numbers (FDN) cause Emergency Calls Only?
In very rare cases, yes. If FDN is enabled on Vodafone UK, your phone may show "Emergency Calls Only." Check and disable FDN only if other steps don't work.

Can a bad SIM cause Emergency Calls Only?
Yes. A damaged, dirty, or loose SIM can prevent network registration. Try reinserting your SIM or testing it in another phone.

Will resetting network settings fix Emergency Calls Only?
It can help if settings are corrupted, but try Airplane mode, restarting, and SIM reinsertion first. Reset network settings only as a last resort.

Why does my Xiaomi say Emergency Calls Only with full signal?
Signal bars show signal strength, not network registration. You may have full signal but still fail to register on the network due to a software glitch, SIM issue, or account problem.

Should I contact my carrier if my phone says Emergency Calls Only?
Yes, if basic troubleshooting doesn't work. Your carrier can check for network issues, account status, or SIM problems.

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...
