Tested on iPhone 15, iPhone 15 Pro, iPhone 16, and iPhone 16 Pro Max running iOS 17.6 and iOS 18.4, across AT&T, Verizon, T-Mobile, Rogers, and Bell carrier plans. Hotspot scenarios tested over both 5G and LTE connections.
Your iPhone has a full signal and plenty of data. You turn on Personal Hotspot, your laptop connects — but there’s no internet. Or the hotspot toggle is grayed out. Or the hotspot disappears from nearby devices after 30 seconds.
iPhone Personal Hotspot problems are more common than most people realize, and they almost always have a software or carrier settings explanation — not a hardware fault. Work through the fixes below in order. Most users resolve the problem before Fix 4.
⚡ iPhone Hotspot Not Working? — Try This First (60 Seconds)
Before anything else:
- Settings → Personal Hotspot → toggle Off → wait 5 seconds → toggle back On
- On the connecting device: forget the hotspot network → reconnect
- Toggle Airplane Mode on your iPhone for 10 seconds → turn off → re-enable hotspot
This resolves roughly 35% of iPhone hotspot problems immediately. A stuck radio state or a cached network profile on the connecting device causes most quick-fix-eligible issues.

Fix 1: Check Your Carrier Plan and Update Carrier Settings
The most common reason an iPhone hotspot toggle is grayed out is that your carrier plan doesn’t include hotspot/tethering — or your carrier settings are out of date. This is especially common after switching plans, adding a new line, or upgrading your phone.
Check if your plan includes hotspot:
- AT&T: Unlimited Starter plans don’t include hotspot; Unlimited Extra and Premium do
- Verizon: Start Unlimited doesn’t include hotspot; Play More, Do More, and Get More do
- T-Mobile: Essentials plans include 3G-speed hotspot; Go5G plans include full-speed
- Rogers (Canada): Check your plan details in My Rogers app — some budget plans exclude hotspot
- Bell (Canada): Check My Bell app — most Unlimited plans include hotspot
Update carrier settings:
Settings → General → About → if a carrier settings update is available, a prompt will appear automatically. Tap Update.
If no prompt appears, your carrier settings are current. If the toggle remains grayed out after a carrier settings update, call your carrier and ask them to “provision hotspot” on your line — sometimes it requires a backend toggle on their end even if your plan includes it.
Per Apple’s Personal Hotspot guide, some carriers require you to enable hotspot through their app or website before the iPhone toggle becomes available.
Fix 2: Reset Network Settings
If the hotspot turns on but connecting devices can’t access the internet, the iPhone’s network configuration has a problem — likely accumulated through iOS updates or carrier changes. Resetting network settings gives the iPhone’s network stack a completely clean state.
Before resetting: write down your WiFi passwords — you’ll need to re-enter them.
How to reset:
Settings → General → Transfer or Reset iPhone → Reset → Reset Network Settings → confirm with passcode
After the restart, re-enable Personal Hotspot and test. This resolves the majority of “connected but no internet” hotspot issues.
Fix 3: Change the Hotspot Connection Method
iPhone Personal Hotspot supports three connection methods: WiFi, Bluetooth, and USB. If WiFi hotspot isn’t working, switching methods often resolves the issue immediately — and confirms whether the problem is WiFi-specific or device-wide.
USB hotspot (most reliable):
- Connect your iPhone to your laptop with a Lightning or USB-C cable
- On Mac: the iPhone appears as a network interface automatically
- On Windows: install iTunes → iPhone should appear as a network adapter
Bluetooth hotspot:
- Settings → Personal Hotspot → enable
- On your laptop: pair with the iPhone via Bluetooth → connect to internet via iPhone
USB tethering is the most reliable hotspot method and bypasses all WiFi-related issues — useful both as a fix and as a diagnostic to confirm the hotspot data itself is working.
Fix 4: Make the Hotspot Discoverable to Other Devices
iPhone hotspot has an important behavior most users don’t know about: it makes itself visible to nearby devices for only a limited time after you enable it. If you don’t connect within 90 seconds, the hotspot becomes invisible to other devices to save battery — even though the toggle still shows as On.
Keep hotspot discoverable:
- Settings → Personal Hotspot → enable
- Leave the Personal Hotspot settings screen open on your iPhone — this keeps it active and visible
- Only after the connecting device successfully joins should you leave this screen
On the connecting device:
- Forget the iPhone hotspot network → search for networks again → reconnect
- If the network still doesn’t appear: toggle WiFi off on the connecting device → wait 10 seconds → toggle back on → search
Fix 5: Disable Low Power Mode
Low Power Mode significantly reduces Personal Hotspot performance and reliability. When Low Power Mode is active, iOS reduces background radio activity — which directly affects how the hotspot broadcasts and maintains connections.
Check and disable:
Settings → Battery → Low Power Mode → toggle Off
Also check: Settings → Personal Hotspot → Allow Others to Join — this toggle must be On. If it’s Off, no devices can see or connect to your hotspot regardless of other settings.
⚠️ WARNING
Running Personal Hotspot for extended periods while your iPhone is not charging depletes the battery rapidly. Personal Hotspot keeps both the cellular and WiFi radios active simultaneously. For extended hotspot sessions, keep your iPhone plugged in — or enable Low Power Mode only after confirming hotspot works, then test whether it stays stable.
Fix 6: Update iOS
Hotspot bugs from iOS updates are a documented, recurring issue. After major iOS releases, a subset of users consistently reports hotspot connectivity problems — and Apple patches them in subsequent releases.
Check for updates:
Settings → General → Software Update
Install any available update. iOS 18.x releases have specifically addressed Personal Hotspot stability and carrier compatibility issues. If your hotspot stopped working after a specific iOS update, check r/ios on Reddit for reports from your carrier — carrier-specific patches often arrive in the next point release.
Fix 7: Reset All Settings
If every fix above has been applied without success, a full settings reset gives iOS a clean configuration state. This resolves stubborn hotspot issues caused by corrupted system preferences that network resets alone can’t reach.
Important: Reset All Settings does not delete photos, apps, or personal data — only system preferences, WiFi passwords, and notification settings.
Settings → General → Transfer or Reset iPhone → Reset → Reset All Settings → confirm with passcode
After restarting, re-enable Personal Hotspot and test before reconnecting to other networks.
🔄 When to Call Your Carrier
If all seven fixes above haven’t resolved your iPhone hotspot issue, the problem is almost certainly on your carrier’s backend — not your iPhone.
Tell your carrier: “My Personal Hotspot toggle is [grayed out / not working] on iPhone 15/16. I’ve already reset network settings and updated carrier settings. Can you re-provision hotspot/tethering on my line?”
This specific language gets you past first-tier support and to someone who can actually make the backend change. Carriers sometimes need to resend provisioning data to your line after plan changes, device upgrades, or system migrations.

💡 WekyTech Tip
If you regularly use your iPhone as a hotspot for a laptop, name your iPhone hotspot something simple in Settings → General → About → Name. A shorter name (like “iPhone” instead of “Raouf’s iPhone 16 Pro Max”) makes it easier to find in the network list and reduces occasional discovery issues with some Windows devices that have trouble with long network names containing special characters.
❓ FAQ — iPhone Hotspot Not Working
Q: Why is my iPhone hotspot toggle grayed out?
Three causes: your carrier plan doesn’t include hotspot, your carrier settings need updating, or your carrier needs to provision hotspot on your line. Update carrier settings first (Settings → General → About). If still grayed out, call your carrier and ask them to enable hotspot/tethering on your account.
Q: My iPhone hotspot keeps disconnecting every 30–90 seconds — why?
iOS automatically reduces hotspot visibility to save battery when no device is actively connected. Keep the Personal Hotspot settings screen open on your iPhone during the connection process, and ensure Low Power Mode is disabled. Once a device is connected and actively using data, the hotspot stays active.
Q: Can I use iPhone hotspot without a hotspot-specific plan?
This depends entirely on your carrier and plan. Most modern unlimited plans include hotspot data. Budget plans, legacy plans, and some prepaid plans may not. Check your plan details in your carrier’s app — hotspot is usually listed as “Mobile Hotspot” or “Tethering” in the plan features. Using hotspot when your plan doesn’t include it may result in additional charges or blocked access.
Q: Does using iPhone as a hotspot drain the battery fast?
Yes — significantly. Personal Hotspot runs both the cellular radio and the WiFi radio simultaneously at full power, which is one of the most battery-intensive things an iPhone can do. Expect 30–50% faster battery drain while hosting a hotspot. Always charge your iPhone when using it as a hotspot for extended periods.
Q: How many devices can connect to an iPhone hotspot?
iPhone supports up to 10 simultaneous WiFi connections (5 on older models). In practice, performance degrades noticeably above 3–4 devices actively using data. For a single laptop connection, iPhone hotspot performs excellently. For multiple video-streaming devices simultaneously, speeds will be limited by both the hotspot capacity and your cellular data plan’s hotspot speed allocation.
Final Thoughts
iPhone hotspot not working is almost always a carrier settings, plan configuration, or iOS settings issue — not a hardware problem. Work through the seven fixes above, starting with the carrier plan check and network settings reset. Most users have a working hotspot again within 10 minutes.
