For an iPhone Personal Hotspot not working, first confirm that the iPhone itself loads pages on cellular data alone. A hotspot only shares that connection, so a device that joins but has no internet usually points back to the iPhone's data, plan, or selected Dual SIM line. Then name the exact failure (the Personal Hotspot option is missing or dimmed, the network is not visible, the password is rejected, the connection drops, a VPN fails only over the hotspot, or the computer does not see the iPhone over USB) and verify carrier support before changing Wi-Fi settings. Enable Allow Others to Join, keep the hotspot page open during discovery, restart and update both devices, and use Maximize Compatibility only when the client needs it.

Key Takeaways

Personal Hotspot depends on carrier and plan support plus working cellular data.

Missing, invisible, rejected-password, connected-no-internet, dropping, and USB failures are different branches.

On Dual SIM, verify which line supplies cellular data before troubleshooting the client.

Maximize Compatibility can help older clients but may reduce performance and Wi-Fi security for connected devices.

Reset Network Settings is a last resort after recovery planning, not an early hotspot step.

For broad diagnosis, use the device and app troubleshooting guide. A hotspot shares the iPhone's cellular connection; it does not turn a broken cellular service into working internet.

Which symptom should you diagnose first with iPhone Personal Hotspot not working?

Use the symptom to choose the next check:

Symptom	First branch
Personal Hotspot is missing, dimmed, or will not turn on	Cellular Data switch, carrier, plan, provisioning, or management
Hotspot exists but the client cannot see it	Allow Others to Join, discovery screen, distance, compatibility
Client sees it but rejects the password	Exact password, keyboard layout, saved network state
Client connects but has no internet	iPhone cellular data, selected line, carrier, destination
Connection drops repeatedly	Signal, power, distance, interference, compatibility, client sleep
USB connection fails	Cable/data capability, trust prompt, Finder/iTunes/device software

Do not change the hotspot password, reset the phone, disable a VPN, and forget the network all at once. Make one reversible change, repeat the same test, and record what changed.

Check carrier, plan, cellular data, and Dual SIM

Apple says to confirm that Personal Hotspot is enabled and supported by the wireless carrier and plan.［1］ If the setting is missing, contact the carrier rather than assuming the iPhone menu is broken. Availability, device limits, throttling, and roaming behavior are carrier- and plan-dependent, so this guide does not promise a particular capability, number of clients, or speed.

Before testing another device:

Turn off Wi-Fi temporarily on the iPhone only if necessary to verify that cellular data itself loads two unrelated destinations.
Check signal and whether a carrier outage or account restriction is reported.
On Dual SIM, open cellular settings and confirm the intended line is selected for cellular data.
Check whether Allow Cellular Data Switching matches the user's intended Dual SIM behavior.
If roaming, verify that the plan permits it and that the appropriate roaming setting is enabled.
If Personal Hotspot is dimmed and will not turn on, turn on cellular data for the line you intend to share, then reopen the setting.

If cellular data fails on the iPhone, stop hotspot troubleshooting and use the iPhone cellular data guide. The client cannot receive internet through a source connection that is not working.

1. Make the hotspot discoverable

On the iPhone providing the connection:

Open Settings > Personal Hotspot or Settings > Cellular > Personal Hotspot.
Turn on Allow Others to Join.
Keep this screen open while the other device searches.
Place the devices close together for the first connection.
Confirm Wi-Fi and Bluetooth are enabled when prompted.

Apple's connection guide documents Wi-Fi, Bluetooth, and USB methods, says a dimmed Personal Hotspot setting calls for turning on cellular data, and asks Windows users to install the latest Apple Devices app or iTunes for Windows before connecting by USB.［2］ For an ordinary Wi-Fi client, open its Wi-Fi list and select the iPhone name shown on the hotspot screen. The iPhone's device name helps identify the network, so confirm you are not selecting a similarly named phone.

On a Dual SIM iPhone, Apple explains how the selected cellular-data number and Allow Cellular Data Switching affect which line supplies data.［3］ Keep that choice aligned with the line and roaming behavior you actually intend to use.

If Family Sharing or Instant Hotspot is involved, first establish whether the client uses that Apple ecosystem path or the ordinary Allow Others to Join password path. Do not mix their expectations during one test.

2. Verify the name and password exactly

On the iPhone, review Wi-Fi Password under Personal Hotspot. On the client:

Select the exact iPhone network name.
Enter the password with the correct capitalization and characters.
Check the client's keyboard layout and avoid copying an accidental trailing space.
If the client saved an older password for this iPhone, forget only that saved hotspot network and reconnect.

Do not post the password in screenshots or support messages. If you change it, every client using the previous password must reconnect. A password rejection is not evidence that cellular service, DNS, or a VPN is broken.

3. Fix “connected but no internet” at the source

When the client joins but cannot reach the internet, look at the iPhone first:

Confirm the iPhone itself can use cellular data with Wi-Fi disconnected.
Confirm the intended Dual SIM line still supplies data.
Test two unrelated destinations to avoid confusing one service outage with a hotspot outage.
Check the carrier account, plan, data allowance, and roaming conditions.
Disconnect and reconnect the client after the iPhone's source connection is healthy.

A VPN can affect routing for some configurations, but it is not the default cause. Record whether a managed or personal VPN is active and follow its owner's supported test procedure. Do not delete VPN profiles, certificates, or management controls merely because the hotspot has no internet.

If the iPhone has internet but only one client does not, compare another client. That separates the hotspot from the original client's Wi-Fi, firewall, account, or software state.

What if a VPN works on Wi-Fi but not over the iPhone hotspot?

If the client browses normally through the hotspot but its VPN will not connect, the hotspot itself is working and the failure sits in the VPN path. Disconnect the VPN and confirm two sites load on the client, then connect the VPN on the client only, not on the iPhone and the client at the same time, so you test one tunnel at a time. If the same VPN works on that client over ordinary Wi-Fi but fails on every hotspot attempt, try the VPN app's alternative protocol setting where its owner allows it, and ask the carrier whether the plan applies tethering limits. Test a work or school VPN only with its IT team's procedure.

4. Handle an invisible or unstable hotspot

Apple recommends restarting both the hotspot provider and the connecting device and installing current software. Also keep the Personal Hotspot page open during discovery, move the devices closer, and retest away from heavy interference.

For recurring drops, record whether the client slept, changed networks, moved out of range, or lost the iPhone name from its Wi-Fi list. Disable automatic joining of an unrelated nearby network on the client only for the controlled test, then restore the preferred behavior.

On supported iPhone models, try Maximize Compatibility when an older or incompatible Wi-Fi client cannot discover or maintain the connection. Apple warns that enabling it can reduce internet performance and Wi-Fi security for devices connected to the hotspot. Treat it as a compatibility tradeoff, not a universal speed fix. Turn it back off if it does not help or if the normal mode is preferred.

5. Troubleshoot USB separately

USB tethering removes Wi-Fi discovery from the path, but it adds cable, trust, and host-software requirements.

Use a cable and adapter that support data, not charge only.
Unlock the iPhone and respond to the trusted-computer prompt only for a computer you control.
On a Mac, confirm the iPhone appears in Finder and in the available network services as documented by Apple.
On Windows, install the latest Apple Devices app or iTunes for Windows and confirm the iPhone is recognized before diagnosing tethering.
Try another known-good data cable or port.

Do not accept a trust prompt on a public or shared computer. Do not install an unknown driver package from a download site. If the phone is recognized for charging but never as a data device, solve the cable, port, trust, or host-software branch before changing hotspot credentials.

6. Restart, update, then consider a network reset

Restart the iPhone and client, install available iOS and client operating-system updates, and repeat the smallest relevant test. Carrier settings may also be updated through supported iPhone prompts. Preserve exact errors and whether the failure affects Wi-Fi, USB, or both.

Only after the problem follows this iPhone, cellular data works, carrier support is confirmed, and the lower-risk checks fail should you consider Reset Network Settings. Read its recovery requirements first: saved networks, unmanaged VPN settings, manual certificate trust, device name, and roaming-related state can need restoration. Do not choose Delete All eSIMs, Reset All Settings, or Erase All Content and Settings as a hotspot shortcut.

Summary

Treat Personal Hotspot as a chain: carrier and plan, working cellular data, the selected Dual SIM line, hotspot visibility and credentials, then the client's Wi-Fi or USB path. Diagnose the exact symptom, make one reversible change, and use Maximize Compatibility only for a demonstrated client-compatibility issue. Reset network settings only after planning recovery and exhausting the narrower branches.

FAQ

Why is Personal Hotspot missing on my iPhone?

The carrier, plan, provisioning, region, or device management may not make it available. If the switch appears but is dimmed, turn on cellular data first; otherwise confirm support with the carrier.

Why can another device not see my iPhone hotspot?

Enable Allow Others to Join, keep the hotspot screen open, move the devices closer, and test Maximize Compatibility if the client needs it.

Why does the hotspot connect but have no internet?

First verify that cellular data works on the iPhone and that the intended Dual SIM line, carrier plan, and roaming state permit data.

Does Personal Hotspot use Wi-Fi or cellular data?

The iPhone shares its cellular internet connection; clients can connect by Wi-Fi, Bluetooth, or USB.

Does Maximize Compatibility make hotspot faster?

Not necessarily. It is a compatibility option and can reduce performance and Wi-Fi security for connected devices.

Why is my hotspot password rejected?

Confirm the exact network name, capitalization, keyboard layout, and current password. Forget only the saved hotspot network if it holds an old password.

Why does USB hotspot charge but not connect?

The cable may be charge-only, the computer may not be trusted, or the required Apple device software may not recognize the iPhone.

Should I reset network settings for a hotspot problem?

Only as a last resort after carrier, cellular, Dual SIM, visibility, password, restart, update, compatibility, and client checks. AethoVPN cannot turn on iPhone tethering when the carrier plan disallows it or cellular data is down; compare without VPN only when you control that configuration and its owner permits the test, then restore it.
