5G Not Working on Phone: Android and iPhone Fix

Quick Answer

When 5G is not working, first confirm that your exact phone model supports your carrier’s 5G network, your plan includes 5G, your SIM or eSIM is correctly activated, and you are inside a covered area.

Turn Wi-Fi off, toggle Airplane Mode, restart the phone, and check that the preferred network setting includes 5G. Temporarily disable Battery Saver or Low Power Mode because some phones may switch to LTE while a power-saving mode is active. A coverage limitation is possible, but plan provisioning, device compatibility, network settings, and SIM conditions can produce the same symptom.

Choose the Symptom That Matches

What you see	What it may suggest	Next safe step
The 5G icon never appears	Coverage, compatibility, plan, SIM, or network-mode issue	Start with Fix 1
5G works only in certain locations	Local coverage or signal conditions become more relevant	Test another known 5G area
5G disappeared after changing SIMs	The SIM, eSIM, data line, or account may need activation	Check the carrier account
One SIM receives 5G but the other does not	Wrong data SIM or different plan provisioning	Select the correct data SIM
The phone stays on LTE while Battery Saver is active	Power-saving behavior may be involved	Temporarily disable Battery Saver
The phone shows 5G but internet does not work	The phone is registered to 5G, but cellular data is failing	Use the no-internet guide
The phone shows 5G but speed is slow	Congestion, signal quality, or the type of 5G may be involved	Use the slow-data guide
5G repeatedly changes to LTE	Coverage, movement, power settings, or network conditions may be involved	Compare locations and settings
The 5G option is missing from Settings	The model, carrier configuration, SIM, or software may not expose it	Check compatibility and contact the carrier
No mobile signal appears at all	The problem is broader than 5G	Troubleshoot the SIM and cellular service

A 5G icon does not guarantee a particular speed. Apple states that its appearance depends partly on carrier-network configuration, while Google notes that mobile performance varies with the network type, traffic, signal conditions, and distance from antennas.

1-Minute Safe Checks

Complete these checks before resetting network settings:

1. Turn Wi-Fi off so you can see the cellular-network indicator.
2. Confirm that Mobile Data or Cellular Data is enabled.
3. Turn Airplane Mode on.
4. Wait about 10 seconds.
5. Turn Airplane Mode off.
6. Restart the phone.
7. Move outdoors or to another location where your carrier advertises 5G coverage.
8. Check that the correct SIM or eSIM is selected for mobile data.
9. Temporarily turn off Battery Saver or Low Power Mode.
10. Check for an Android, iOS, or manufacturer software update.
11. Ask another person using the same carrier whether 5G works in the same location.
12. Check the carrier’s official coverage and outage information.

Google, Apple, and Samsung all place carrier support, plan eligibility, coverage, network selection, and a restart among the main checks when 5G is unavailable.

Fix 1: Confirm That the Exact Phone Model Supports the Carrier’s 5G Network

DIAGNOSTIC TEST

Use This When

Use this fix when:

• The phone has never connected to 5G.
• The phone was imported from another country.
• It was originally sold by a different carrier.
• The 5G option is missing.
• The same SIM gets 5G in another phone.
• The phone’s product name includes “5G,” but it still connects only to LTE.

Why It May Help

A phone being marketed as 5G-capable does not mean every regional or carrier variant works with every 5G network. Google states that not every Pixel 4a (5G) or later model works on every 5G network. Apple similarly requires a supported iPhone, a compatible carrier, and a 5G plan.

Steps

1. Open Settings.
2. Open About phone, About device, or General → About.
3. Record the full model number, not only the marketing name.
4. Find the manufacturer’s official specification page for that exact model.
5. Confirm that the model supports 5G.
6. Ask your carrier whether that exact model or regional variant is approved for its 5G network.
7. Confirm whether the phone is carrier-locked.
8. Check whether the carrier requires a particular SIM, eSIM, firmware version, or device certification.

Expected Result

The comparison should establish whether the exact device variant is expected to work with the carrier’s 5G service.

What the Result Means

The exact model is supported:
Continue with coverage, plan, SIM, and network-mode checks.

The exact model is not supported:
Changing basic settings is unlikely to create reliable 5G compatibility.

The carrier cannot confirm compatibility:
Do not assume that a matching frequency alone guarantees service. Carrier certification, provisioning, and regional software may also matter.

Do not install unofficial firmware or use hidden dialer menus to force unsupported 5G modes.

Fix 2: Confirm 5G Coverage, Plan Eligibility, and SIM Provisioning

OFFICIALLY DOCUMENTED STEP

Use This When

Use this fix when 5G works in some locations, disappeared after changing plans or SIMs, or has never worked on the current account.

Why It May Help

A 5G-capable phone still needs:

• A carrier offering 5G
• An eligible mobile plan
• An activated SIM or eSIM
• 5G coverage in the current location
• Correct carrier provisioning

Apple lists a supported carrier and 5G plan as requirements. Samsung also advises checking the plan, SIM compatibility, and coverage before changing phone settings.

Steps

1. Open the carrier’s official coverage map.
2. Confirm that 5G is listed for your location.
3. Check whether the carrier reports an outage.
4. Sign in to your carrier account.
5. Confirm that the plan includes 5G access.
6. Confirm that the SIM or eSIM is active.
7. Ask whether the account requires 5G activation or reprovisioning.
8. Ask whether the existing physical SIM is compatible with 5G.
9. Confirm that the phone’s IMEI and exact model are supported.
10. Restart the phone after the carrier makes any account change.

Expected Result

The carrier should confirm whether the phone, plan, SIM, account, and location are eligible for 5G.

What the Result Means

5G works in another covered location:
The original location or local network conditions become more relevant.

Other users on the same carrier also lack 5G:
A local outage or coverage condition becomes more plausible.

The carrier says the SIM is not provisioned for 5G:
Phone-side resets are unlikely to help until the account or SIM is corrected.

The plan does not include 5G:
Changing Android or iPhone settings will not add plan eligibility.

Fix 3: Toggle Airplane Mode and Restart the Phone

SAFE FIRST CHECK

Use This When

Use this fix when 5G previously worked but suddenly disappeared.

Why It May Help

Airplane Mode disconnects the phone from the mobile network. Turning it off makes the device attempt a fresh network registration. Apple specifically includes toggling Airplane Mode when the 5G icon is missing, and Google recommends shutting down or toggling Airplane Mode during mobile-connectivity troubleshooting.

Steps

1. Turn Wi-Fi off.
2. Turn Airplane Mode on.
3. Wait about 10 seconds.
4. Turn Airplane Mode off.
5. Wait for the carrier name and signal bars to return.
6. Check whether the 5G indicator appears.
7. If it does not, power the phone off completely.
8. Wait about 30 seconds.
9. Turn the phone back on.
10. Test again.

Expected Result

The phone should perform a new registration attempt with the carrier.

What the Result Means

• If 5G returns, a temporary network-registration or phone-process issue was involved.
• This result does not identify whether the interruption originated from the phone or the carrier.

Fix 4: Check Mobile Data and the Active Data SIM

SAFE FIRST CHECK

Use This When

Use this fix on a Dual SIM phone or when calls work but mobile data remains on LTE or does not connect.

Android Steps

1. Open Settings.
2. Open Network & internet, Connections, SIM cards, or Mobile network.
3. Confirm that the intended SIM is enabled.
4. Turn on Mobile data.
5. Find the default SIM settings.
6. Select the 5G-enabled line for mobile data.
7. Turn Wi-Fi off.
8. Wait for the network indicator to update.

On supported Pixel phones, Google places these controls under:

Settings → Network & internet → SIMs

iPhone Steps

1. Open Settings.
2. Tap Cellular or Mobile Data.
3. Confirm that Cellular Data is on.
4. If using Dual SIM, tap Cellular Data.
5. Select the line that has the 5G plan.
6. Open that line’s data options.
7. Confirm that a 5G option is available.

Apple states that Dual SIM users must select the number they want to configure before changing 5G options.

Expected Result

The phone should use the SIM or eSIM that is correctly provisioned for 5G data.

What the Result Means

• If 5G appears after changing the data line, the previous SIM selection was involved.
• If the correct line was already selected, continue with the platform-specific network mode.

Fix 5: Enable a Network Mode That Includes 5G on Android

OFFICIALLY DOCUMENTED STEP

Use This When

Use this fix when an Android phone remains on LTE and its network mode was changed previously.

General Android Steps

1. Open Settings.
2. Open Network & internet, Connections, or Mobile network.
3. Select the active data SIM.
4. Open Preferred network type or Network mode.
5. Choose an automatic option that includes 5G, such as:
   • 5G recommended
   • 5G/LTE/3G/2G automatic
   • 5G/LTE automatic
6. Wait for the phone to reconnect.
7. Turn Wi-Fi off.
8. Check the status bar.

Available options depend on the phone, software version, SIM, carrier, and region. Google documents a 5G preferred-network option on supported Pixel phones, while Samsung instructs Galaxy users to select a Network mode containing 5G.

Samsung Galaxy Path

Settings → Connections → Mobile networks → Network mode

Select an option containing 5G.

Google Pixel Path

Settings → Network & internet → SIMs → [carrier] → Preferred network type

Select 5G when the carrier exposes that option.

Expected Result

The phone should be allowed to connect to 5G when the service is supported and available.

What the Result Means

5G returns:
The previous network-mode setting was involved.

No 5G option appears:
The carrier, device model, SIM, software, or region may be controlling the available options.

Do not force 5G-only mode with an unofficial app. Automatic modes allow the phone to fall back to LTE when 5G coverage is unavailable.

Fix 6: Check 5G Auto and 5G On on iPhone

OFFICIALLY DOCUMENTED STEP

Use This When

Use this fix on an iPhone 12 or later when the phone stays on LTE in a covered area.

Steps

1. Open Settings.
2. Tap Cellular or Mobile Data.
3. Tap Cellular Data Options or Mobile Data Options.
4. If using Dual SIM, choose the correct line.
5. Tap Voice & Data.
6. Select:
   • 5G Auto for automatic switching between 5G and LTE
   • 5G On to use 5G whenever it is available
7. Avoid selecting LTE when you are trying to connect to 5G.
8. Return to the Home Screen.
9. Turn Wi-Fi off.
10. Check the cellular indicator.

Apple explains that 5G Auto may switch to LTE when 5G does not provide a noticeably better experience. Selecting 5G On keeps 5G enabled whenever it is available, but it may use more battery.

Expected Result

The iPhone should be permitted to use the carrier’s available 5G network.

What the Result Means

• If 5G appears after changing from LTE to 5G Auto or 5G On, the previous Voice & Data selection was involved.
• If the entire 5G menu is unavailable, confirm the exact iPhone model, SIM, plan, carrier support, and region.

Fix 7: Temporarily Disable Battery Saver or Low Power Mode

DIAGNOSTIC TEST

Use This When

Use this fix when the phone switches to LTE as the battery level falls or while a power-saving mode is active.

Google Pixel

Google states that a 5G-capable Pixel may use 4G while Battery Saver is enabled, depending on the carrier network.

1. Swipe down from the top of the screen.
2. Turn Battery Saver off temporarily.
3. Wait for the phone to reconnect.
4. Check whether 5G appears.

iPhone

Apple states that Low Power Mode turns off 5G on most supported devices, with stated exceptions for some activities on iPhone 12 and iPhone 13 models.

1. Open Settings.
2. Tap Battery.
3. Turn Low Power Mode off temporarily.
4. Wait for the network indicator to update.
5. Test again.

Other Android Phones

Manufacturers may manage 5G differently in power-saving modes. Search the phone’s Settings app for:

• Battery Saver
• Power saving
• Ultra power saving
• Performance mode

Use the manufacturer’s official guidance for the exact model.

Expected Result

5G may return if the power-saving mode was causing the phone to prefer LTE.

What the Result Means

• If disabling power saving restores 5G, the behavior may be intentional rather than a fault.
• Restore your preferred power setting after testing when continuous 5G is not necessary.

Fix 8: Install Phone Software Updates

SAFE FIRST CHECK

Use This When

Use this fix when 5G stopped after an operating-system change, a new SIM activation, or a carrier-network update.

Android Steps

1. Connect to reliable Wi-Fi.
2. Charge the phone sufficiently.
3. Open Settings.
4. Open System update or Software update.
5. Install available updates.
6. Restart the phone.
7. Turn Wi-Fi off.
8. Test 5G.

Samsung recommends checking for current phone software before following its 5G troubleshooting steps. Google also includes system updates in its mobile-connectivity guidance.

iPhone Steps

1. Connect to reliable Wi-Fi.
2. Open Settings.
3. Tap General.
4. Tap Software Update.
5. Install an available update.
6. Restart the iPhone.
7. Check the 5G settings again.
8. Test with Wi-Fi turned off.

Expected Result

The phone should use its current manufacturer and carrier configuration.

What the Result Means

• If 5G returns after updating, the previous phone software or carrier configuration may have contributed.
• An update cannot add hardware support to an incompatible regional phone model.

Fix 9: Reset Mobile Network Settings

CONDITIONAL STEP

Use This When

Use this only after confirming:

• The phone supports the carrier’s 5G network.
• The plan and SIM are eligible.
• 5G coverage exists.
• The correct SIM is selected.
• The network mode includes 5G.
• Restarting and updating did not help.

Before You Reset

A network reset does not normally erase photos or personal files, but it can remove saved network information.

Depending on the phone, it may reset:

• Cellular settings
• Saved Wi-Fi networks
• Wi-Fi passwords
• Bluetooth pairings
• VPN settings
• APN changes
• Data-roaming preferences

Read the phone’s warning before confirming.

Google Pixel Steps

1. Open Settings.
2. Tap System.
3. Tap Reset options.
4. Tap Reset mobile network settings.
5. Confirm the reset.
6. Restart the phone.
7. Test 5G.

Google documents a separate mobile-network reset on supported Pixel phones.

iPhone Steps

1. Open Settings.
2. Tap General.
3. Tap Transfer or Reset iPhone.
4. Tap Reset.
5. Tap Reset Network Settings.
6. Enter the passcode if requested.
7. Allow the iPhone to restart.
8. Reconnect to Wi-Fi when needed.
9. Test 5G.

Apple states that Reset Network Settings removes network configurations, including previously used Wi-Fi networks and certain VPN, cellular, and certificate settings, without using the full erase option.

Expected Result

The phone should reconnect using default network settings.

What the Result Means

• If 5G returns, a stored network configuration may have contributed.
• If nothing changes, do not repeatedly reset the phone. Contact the carrier for provisioning and compatibility checks.

Fix 10: Compare the SIM, Phone, and Location

DIAGNOSTIC TEST

Use This When

Use this test when the carrier says the account and coverage are correct but 5G remains unavailable.

Tests

1. Place the SIM in another compatible 5G phone when the carrier permits it.
2. Test another active 5G SIM in the affected phone.
3. Test both phones in the same location.
4. Turn Wi-Fi off on both devices.
5. Use the same carrier and plan type where possible.
6. Compare the status-bar indicators.
7. Repeat the comparison in another covered location.

What the Result Means

Your SIM gets 5G in another compatible phone:
The original phone’s model, settings, software, or cellular hardware becomes more relevant.

Another eligible SIM gets 5G in your phone:
The original SIM, account, or provisioning becomes more relevant.

Neither phone gets 5G in the same location:
Coverage, outage, or local carrier conditions become more plausible.

The phone receives 5G in another location:
The original location is the stronger lead.

These comparisons narrow down the affected side, but they do not confirm a specific hardware component or carrier fault.

When 5G Coverage Limitation Is More Likely

Coverage limitation becomes more plausible when:

• 5G works in other locations.
• Other people using the same carrier also lose 5G in the area.
• The phone falls back to LTE indoors but receives 5G outdoors.
• The carrier’s map shows partial or outdoor-only coverage.
• 5G changes to LTE while traveling.
• The carrier confirms maintenance or an outage.
• The phone, SIM, plan, and network mode are already verified.

Samsung states that Galaxy phones automatically fall back to LTE or another supported network when 5G is unavailable. Apple’s 5G Auto setting can also move an iPhone to LTE when 5G does not provide a noticeably better experience.

Falling back to LTE is not, by itself, proof that the phone is faulty.

When the Problem Is Probably Not Coverage

Coverage is less likely to be the main issue when:

• The same SIM receives 5G in another phone at the same location.
• Other phones on the same carrier receive 5G beside you.
• Your phone has never supported the carrier’s required 5G network.
• The account does not include 5G.
• The carrier says the SIM or eSIM is not provisioned.
• The active data SIM is incorrect.
• The preferred network mode is set to LTE.
• Battery Saver or Low Power Mode is forcing a lower network type.
• The phone has a SIM or cellular hardware error.

When 5G Appears but Internet Does Not Work

When the 5G icon is visible but webpages and apps cannot connect, the dominant problem is no longer simply missing 5G.

Check:

• Mobile-data allowance
• Carrier provisioning
• APN settings
• VPN or Private DNS
• Data restrictions
• Carrier outage

Use the dedicated Mobile Data Connected but No Internet Fix instead of repeating the missing-5G steps. Do not edit the APN merely because the 5G icon is absent. Use only the carrier’s official APN values.

When 5G Is Connected but Slow

A slow connection requires a different troubleshooting path. Possible factors include congestion, distance from the tower, indoor obstruction, signal quality, and the type of 5G deployed by the carrier.

Use the Slow Mobile Internet on Phone Fix Guide when 5G is already connected but performance is poor.

When to Contact the Carrier

Contact the carrier when:

• The plan may not include 5G.
• The SIM or eSIM needs activation.
• 5G disappeared after changing plans or devices.
• The exact phone model needs compatibility confirmation.
• The carrier controls the available network-mode options.
• Other users on the carrier also lack 5G.
• The carrier may have an outage.
• The SIM receives LTE but never 5G in covered locations.
• Network resets and updates made no difference.

The carrier can confirm coverage, plan eligibility, SIM provisioning, account restrictions, outages, and device certification. Phone settings cannot correct a carrier-side coverage or provisioning problem.

When the Problem May Be Phone-Related

A device-specific problem becomes more plausible when:

• The SIM receives 5G in another compatible phone.
• Another working 5G SIM cannot receive 5G in the affected phone.
• The exact model is carrier-compatible.
• The problem continues in several covered locations.
• Cellular service became unreliable after a drop or liquid exposure.
• The phone repeatedly reports SIM or modem errors.
• The problem began after unofficial firmware modification.

Do not open the phone, probe antenna contacts, or install generic modem firmware.

Use manufacturer-specific diagnostics or professional inspection when controlled SIM comparisons consistently point to the phone.

Common Mistakes

• Assuming every phone labeled “5G” works with every carrier.
• Checking for the 5G icon while Wi-Fi is connected.
• Treating LTE fallback as automatic proof of a fault.
• Ignoring the active data SIM on a Dual SIM phone.
• Selecting LTE in the preferred-network menu.
• Testing in only one location.
• Assuming full signal bars guarantee 5G coverage.
• Editing APN settings before confirming the symptom.
• Forcing 5G-only mode through an unofficial app.
• Installing another region’s firmware.
• Replacing the SIM before asking the carrier to check provisioning.
• Factory-resetting the phone before checking coverage and compatibility.

How This Guide Was Verified

Last technically checked:
July 26, 2026

Research method:
The website’s Network Fix archive and its existing LTE, weak-signal, slow-data, and connected-without-internet articles were checked for overlapping intent. Current Google Pixel, Apple, and Samsung support pages were opened directly, their visible titles were checked, and their instructions were matched to the relevant procedures.

Physically tested:
No documentation reviewed.

Applies to:
5G-capable Android phones and iPhones using a compatible carrier, mobile plan, SIM or eSIM, and covered location.

Important limitation:
5G coverage, network types, frequency support, plan eligibility, SIM requirements, network-mode choices, roaming, and menu paths vary by country, carrier, phone model, regional variant, and software version.

Data-loss risk:
Conditional. Coverage checks, Airplane Mode, restarting, SIM selection, network-mode changes, and power-mode testing are non-destructive. Resetting network settings removes saved connection information but should not erase personal photos or media. Factory reset is not included.

Final Steps

• First confirm that the exact phone model, plan, SIM, carrier, and location support 5G. Then check the active data SIM and select an automatic network mode that includes 5G.
• Temporarily disable Battery Saver or Low Power Mode, toggle Airplane Mode, restart the phone, and install available updates.
• Use a network reset only after the carrier confirms eligibility and coverage. When the SIM receives 5G in another compatible phone but the affected phone does not, contact the manufacturer or a qualified service provider instead of forcing unsupported settings or installing unofficial firmware.
