Xiaomi 5G Not Working on EE After HyperOS Update

Xiaomi 5G Not Working on EE After HyperOS Update – UK Fix

This guide helps if your Xiaomi 5G stopped working on EE after a HyperOS update – you may have 4G only, no 5G icon, or 5G appears but speeds are slow. If your 5G disappeared without any software update, see our general Xiaomi 5G troubleshooting guide.

Quick Answer:
If 5G stopped working on EE after a HyperOS update, first go to Settings → SIM cards & mobile networks → EE SIM → Preferred network type → ensure it's set to 5G/4G/3G auto (not "4G only"). Then restart your phone. If that doesn't work, toggle Airplane mode ON for 30 seconds, then OFF. Also check APN settings and reset to default if needed. If 5G still doesn't appear, check EE's 5G coverage and confirm your plan includes 5G in the My EE app or by contacting EE support.

Applies to Redmi, POCO and Xiaomi Phones

This guide applies to Xiaomi, Redmi and POCO devices running MIUI or HyperOS on the EE UK network. Most Xiaomi, Redmi and POCO devices officially sold for the UK market support EE's required 5G bands, although imported models may miss one or more EE 5G bands, which can reduce coverage in certain areas.

Check These First

Before going through the detailed sections, check these basic items:

• Mobile data is turned on – Settings → SIM cards & mobile networks → EE SIM → Mobile data → ON.
• Airplane mode is off – Check the quick settings panel.
• Your SIM is inserted correctly – Power off → remove SIM → reinsert firmly.
• Your software update completed successfully – Check Settings → About phone → System update.
• You're in an EE 5G coverage area – Check EE's coverage map.

Before You Assume 5G Is Broken

• 5G is not displayed continuously on every Xiaomi device – The phone may switch to 4G automatically when idle.
• Xiaomi devices may switch between 4G and 5G automatically depending on network demand – Seeing 4G briefly doesn't always indicate a fault.
• Indoor coverage is often weaker than outdoor coverage – 5G signal may not reach inside buildings even if outdoor coverage is good.
• The phone may drop to 4G to save battery – This is normal behaviour during idle periods.

Section 1 – No 5G Icon After Update (Most Common)

If 5G worked before the update but now only shows 4G, the update likely reset your preferred network type to "4G only" or "3G only".

Try these in order:

1. Check preferred network type – Settings → SIM cards & mobile networks → EE SIM → Preferred network type → Select 5G/4G/3G auto (not "4G only" or "3G only").
2. Restart your phone – After changing, restart and wait 2-3 minutes for 5G to reconnect.
3. Check 5G icon – The 5G icon should now appear in the status bar.
4. Toggle Airplane mode – ON for 30 seconds, then OFF. This forces reconnection.
5. If still missing – Proceed to Section 5.

Section 2 – 5G Icon Shows but No Internet

If you see a 5G icon but websites won't load, the issue is APN or data allowance.

Try these in order:

1. Check data allowance – Open the EE app or My EE account. If you've exceeded your allowance, data may be blocked.
2. Reset APN to default – Settings → SIM cards & mobile networks → EE SIM → Access Point Names → three dots → Reset to default → Restart.
3. Check APN manually – In most cases, EE uses the APN everywhere with no username or password. If reset doesn't work, check and correct manually. Don't create duplicate APN profiles unless EE support specifically recommends it.
4. Toggle Airplane mode – ON for 30 seconds, then OFF. This forces reconnection.

Section 3 – 5G Icon Appears and Disappears (Coverage or SA Mode)

If 5G appears and disappears, the issue is usually coverage or 5G Standalone (SA) mode.

Try these in order:

1. Check EE 5G coverage – Visit EE's coverage map for your postcode. If coverage is patchy, this is expected.
2. Switch to 4G – Set Preferred network type to 4G/3G/2G auto. If 4G works consistently, 5G coverage in your area is weak.
3. Move to a different location – 5G coverage can vary significantly even within the same building.
4. If available, check 5G SA mode – Very few Xiaomi devices expose SA/NSA controls. Skip this step if you don't see the option. If your device provides advanced 5G mode options in Developer Options, you can temporarily switch from Standalone (SA) to Non-Standalone (NSA) mode for testing.

Section 4 – 5G Slow After Update (Congestion, Throttling, or Weak Signal)

If 5G appears but is very slow after the update, the issue is likely congestion, throttling, or weak signal causing frequent fallback to LTE.

Try these in order:

1. Check data allowance – If you've exceeded your limit, speeds may be reduced.
2. Test at different times – If speeds improve at quiet hours (e.g., 6am), congestion is the cause. No phone setting will fix this.
3. Test video speed specifically – Use Fast.com. If Speedtest.net shows fast but Fast.com is slow, your carrier may be managing certain types of traffic.
4. Test outdoors – Indoor 5G coverage is often weaker. Test outdoors to see if speeds improve.
5. Disable VPN temporarily – Some VPNs can limit 5G speeds.
6. Disable Private DNS temporarily – Settings → Connection & sharing → Private DNS → Off.
7. Disable Battery Saver – Settings → Battery → Battery saver → OFF. Battery Saver may restrict background network activity and, on some devices, may reduce 5G usage to improve battery life.

Section 5 – 5G Disappeared Entirely (Carrier Provisioning)

If 5G is completely gone after the update and none of the above work, the issue may be carrier provisioning.

Try these in order:

1. Check your plan includes 5G – Check your plan in the My EE app or contact EE customer support to confirm that 5G is enabled on your account. Some older plans or PAYG may not include 5G.
2. Call EE – 150 or 0800 956 6000 – ask them to check "5G access is enabled on your account" and send a new SIM profile.
3. Check SIM age – If your SIM is older than 3-4 years, it may not support 5G. Request a replacement.
4. Check device compatibility – Imported models may miss one or more EE 5G bands, which can reduce coverage in certain areas.
5. Reset network settings – Settings → Connection & sharing → Reset Wi-Fi, mobile networks, and Bluetooth (last resort – removes saved Wi-Fi passwords).

Why Did 5G Stop Working on EE After HyperOS Update?

• Preferred network type reset (most common) – The update may have set it to "4G only".
• APN settings reset – The update may have changed or cleared APN settings.
• Carrier provisioning issue – The update may have triggered a carrier profile refresh that affected 5G.
• 5G SA mode enabled – Some updates enable SA mode, which can be less stable.
• Network congestion – More users on 5G in your area.
• Data allowance exceeded – You may have run out of data.
• Weak signal causing frequent fallback to LTE – The phone may constantly switch between 5G and 4G.
• Carrier settings updated after HyperOS installation – The update may have introduced new carrier configuration that takes time to settle.
• Temporary network registration failure after the update – The phone may not have re-registered for 5G services.

⚠️ What NOT to Do

• Don't factory reset your phone – This is rarely needed for 5G issues.
• Don't assume your phone is broken – Test your SIM in another 5G phone first.
• Don't ignore your plan – Check that your EE plan includes 5G.

Quick Questions

Why did my 5G disappear after HyperOS update on EE?
Most commonly the preferred network type reset to "4G only". Go to Settings → SIM cards & mobile networks → EE SIM → Preferred network type → select 5G/4G/3G auto.

How do I fix 5G on EE after update?
1. Check preferred network type
2. Check APN settings
3. Check data allowance
4. Toggle Airplane mode
5. Restart your phone

Does EE support 5G on Xiaomi?
Yes, EE supports 5G on most recent UK Xiaomi models that officially support EE's 5G bands.

Will resetting network settings fix 5G?
It can help if settings are corrupted. Try the preferred network type and APN reset first.

How do I check my EE 5G coverage?
Visit EE's coverage map or check in the My EE app. If coverage is weak, 5G won't work regardless of settings.

Why does my Xiaomi switch between 5G and 4G after the update?
This is often normal network behaviour. Xiaomi devices automatically switch between 5G and 4G depending on signal quality, battery optimisation, and network conditions. If the phone quickly returns to 5G in areas with good coverage, this is usually not a fault.

Why does my Xiaomi show 4G in areas where it used to show 5G?
This can happen due to network optimisation, carrier maintenance, preferred network reset, or temporary congestion. If 5G returns later in the same location, it's likely a temporary network condition rather than a permanent fault.

Why is my Xiaomi connected to 5G but speeds are the same as 4G?
Because the phone may be connected to a low-band 5G cell, the network may be congested, or your connection may be using Non-Standalone (NSA) 5G where performance is similar to LTE in some locations.

Xiaomi 5G disappeared after HyperOS update – what should I do?
Check preferred network type first. If that's correct, check APN settings and data allowance. If still not working, contact EE to confirm 5G is enabled on your account.
