When your iphone hotspot not working, you lose the ability to share your cellular connection with laptops, tablets, and other devices. This problem affects every iPhone model and can appear suddenly after an iOS update, a carrier change, or seemingly without any trigger at all. Personal Hotspot failures range from the feature being completely missing from Settings to the hotspot broadcasting but refusing to connect any device.
The fixes below are organized from quickest to most thorough. Most users solve the problem within the first four steps. If you have already tried the obvious things like toggling the hotspot off and on, skip ahead to the network reset and carrier configuration sections where the real solutions live.
Why iPhone Hotspot Stops Working
Personal Hotspot relies on three systems working together: your cellular data connection, the WiFi or Bluetooth radio broadcasting the hotspot signal, and the software layer that manages tethering permissions. A failure in any one of these breaks the entire chain.
The most common cause is a conflict between iOS settings and carrier provisioning. When you update iOS or change your carrier settings, the tethering configuration can get corrupted. The second most common cause is the WiFi radio getting stuck in a state where it cannot simultaneously maintain a hotspot and other connections. The third cause is carrier restrictions, where your mobile plan either does not include tethering or has reached a tethering data limit.
Fix 1: Toggle Personal Hotspot Off and On
Open Settings, tap Personal Hotspot, and turn off Allow Others to Join. Wait 10 seconds, then turn it back on. This simple reset clears temporary connection states that prevent devices from discovering the hotspot. If the toggle was already off, turn it on and verify your hotspot name and password appear below the toggle.
Fix 2: Restart Your iPhone
A restart clears all cached network states and reinitializes the cellular and WiFi radios. On iPhone X and newer, press and hold the Side button and either Volume button until the power off slider appears. Drag to shut down, wait 30 seconds, then press the Side button to turn it back on. After the restart, check if Personal Hotspot appears in Settings and functions correctly.
Fix 3: Toggle Airplane Mode
Turning Airplane Mode on disconnects all wireless radios simultaneously, then turning it off forces a fresh connection to your carrier network. This is more effective than toggling individual radios because it resets the cellular registration, which can fix provisioning glitches.
Open Settings and enable Airplane Mode. Wait 15 seconds. Disable Airplane Mode and wait for your cellular connection to restore (you will see signal bars return). Then try enabling Personal Hotspot again.
Fix 4: Check Cellular Data Is Active
Personal Hotspot cannot work without an active cellular data connection. Go to Settings, then Cellular, and confirm that Cellular Data is turned on. If you are using dual SIM or eSIM, make sure the correct line is set as the data line. Tap Cellular Data under the Cellular section to select which SIM provides the data connection for hotspot.
Fix 5: Update Carrier Settings
Carrier settings updates contain configuration data that enables features like Personal Hotspot, VoLTE, and WiFi Calling. An outdated carrier profile can prevent tethering from working even when your plan supports it.
Go to Settings, then General, then About. Wait on this screen for 15 to 30 seconds. If a carrier settings update is available, a popup will appear asking you to install it. Tap Update. After the update installs, check Personal Hotspot again.
Fix 6: Reset Network Settings
This is the most effective single fix for persistent hotspot problems. It clears all WiFi passwords, Bluetooth pairings, VPN configurations, and cellular settings, forcing iOS to rebuild the entire network stack from scratch.
Go to Settings, then General, then Transfer or Reset iPhone, then Reset, and tap Reset Network Settings. Enter your passcode when prompted. Your iPhone will restart. After it boots, you will need to reconnect to WiFi networks and re-pair Bluetooth devices. Personal Hotspot should now appear and function correctly.
Fix 7: Re-Insert SIM Card or Reset eSIM
For physical SIM users, power off your iPhone, remove the SIM card using a SIM eject tool, wait 30 seconds, reinsert the SIM, and power on. This forces a fresh carrier registration that can resolve tethering authorization issues.
For eSIM users, the equivalent step is to go to Settings, then Cellular, select your eSIM line, and look for an option to update or refresh the eSIM profile. If the problem persists, you may need to remove and re-add the eSIM, which requires contacting your carrier for a new QR code or activation.
Fix 8: Update iOS
Apple frequently patches hotspot bugs in iOS updates. Go to Settings, then General, then Software Update. Install any available update and test the hotspot after the restart. If you started experiencing the problem after a specific iOS update, check Apple’s support forums and the Apple Community discussions to see if others report the same issue and whether a newer version addresses it.
Fix 9: Maximize Compatibility Mode
On iPhone 12 and newer, there is a Maximize Compatibility toggle in Personal Hotspot settings. When enabled, this forces the hotspot to broadcast on the 2.4 GHz band instead of 5 GHz. Older laptops and some devices cannot connect to 5 GHz hotspots, so enabling this option can fix connection failures with specific devices even though the hotspot itself is working.
Fix 10: Change Hotspot Password
Corrupted hotspot passwords can prevent connections silently. Go to Settings, then Personal Hotspot, tap the WiFi Password field, delete the current password, and type a new one using only letters and numbers (avoid special characters). Tap Done and try connecting your other device with the new password.
Fix 11: Contact Your Carrier
If none of the above fixes work, the problem may be on your carrier’s side. Some mobile plans do not include tethering, and others have separate tethering data caps. Call your carrier’s support number and specifically ask them to verify that personal hotspot and tethering are provisioned on your account. Ask them to send a fresh carrier configuration to your device.
Fix 12: DFU Restore as Last Resort
A DFU (Device Firmware Update) restore erases everything on your iPhone and reinstalls iOS at the firmware level. This eliminates any deep software corruption that survived a normal reset. Back up your iPhone to iCloud or your computer before proceeding. Connect to your Mac or PC, put your iPhone into DFU mode using the button sequence for your specific model, and restore through Finder or iTunes. After restoring and setting up your iPhone, test Personal Hotspot before restoring your backup to confirm the issue is software-related.
Frequently Asked Questions
Why did Personal Hotspot disappear from my Settings?
Personal Hotspot disappears when iOS cannot detect tethering authorization from your carrier. This happens after SIM changes, carrier setting resets, or plan downgrades. Updating carrier settings through Settings, General, About usually brings it back. If not, contact your carrier to re-provision tethering on your account.
Can I use iPhone hotspot while connected to WiFi?
On iPhone models supporting WiFi 6E or later, iOS can share a WiFi connection through the hotspot rather than cellular data. However, on most models, enabling Personal Hotspot disconnects you from WiFi and shares your cellular data connection instead. You cannot simultaneously use WiFi for internet and broadcast a WiFi hotspot on the same radio.
How many devices can connect to iPhone hotspot at once?
Apple officially supports up to 5 simultaneous connections via WiFi to an iPhone hotspot. You can also connect devices via Bluetooth (1 device) or USB (1 device) alongside the WiFi connections. Performance degrades as more devices share the cellular bandwidth.
Does iPhone hotspot use a lot of battery?
Yes, running a personal hotspot is one of the most battery-intensive activities because it keeps both the cellular radio and WiFi transmitter active simultaneously. Expect approximately 10 to 15 percent battery drain per hour of active hotspot use. Connecting devices via USB instead of WiFi reduces battery consumption because the USB connection can simultaneously charge the iPhone.
