Mobile hotspot not working? Walk through this troubleshooting tree

Mobile hotspot fails in four different ways, and each one has a different fix. “Mobile hotspot not working” is the umbrella term, but until you know which specific failure you’re hitting, you can’t actually solve it.

This piece is a decision tree. Read the first question, pick the answer that matches your situation, and jump to that section. The fix should take five minutes or less.

Which problem are you having?

1. The hotspot option is missing or greyed out, won’t even turn on. → Jump to section A.
2. The hotspot turns on, but your laptop or tablet can’t see it in the Wi-Fi list. → Section B.
3. Connected devices see the hotspot and join, but there’s no internet. → Section C.
4. Everything works for a few minutes, then the connection drops. → Section D.

Pick one and skip the rest.

A. The hotspot won’t turn on at all

If the toggle in Settings does nothing, is greyed out, or the entire Personal Hotspot menu is missing, you’re hitting one of seven common causes. Quick checklist:

• Cellular Data is off. Turn it on in Settings → Cellular. Without cellular data, there’s nothing to share.
• Your carrier plan doesn’t include tethering. Check your account online. Some prepaid and MVNO plans exclude it.
• eSIM glitch after switching lines. Toggle the line off and on in Settings → Cellular.
• Recent iOS update broke it. Update to the latest point release.
• Restrictions or Screen Time are blocking it. Check Settings → Screen Time → Content & Privacy Restrictions → Cellular Data Changes.
• Network settings corrupt. Run Settings → General → Transfer or Reset iPhone → Reset → Reset Network Settings. You’ll need to re-enter Wi-Fi passwords after.

We wrote a full piece on the seven greyed-out hotspot causes with detailed fixes for each.

On Android, the equivalent paths are Settings → Network & internet → Hotspot & tethering → Wi-Fi hotspot. If it’s greyed out, the cause is usually the same as iPhone: data is off, the carrier doesn’t include tethering, or restrictions are on at the carrier level.

B. The hotspot is on, but no device sees it

Your iPhone says the hotspot is active, but your laptop doesn’t see it in the Wi-Fi list. This is almost always one of three things.

Maximize Compatibility is off and your device only supports 2.4 GHz

By default, iOS broadcasts the hotspot on 5 GHz. Older laptops, most game consoles, smart TVs, and some IoT devices only see 2.4 GHz networks.

Fix: Settings → Personal Hotspot → Maximize Compatibility → On. This switches the hotspot to 2.4 GHz. Connected devices may need to forget the network and reconnect after the switch.

You’re out of range

Personal Hotspot has a much shorter Wi-Fi range than a normal router. Inside a coffee shop with a laptop in the same backpack, fine. Across a hotel room, sometimes. Across two rooms, almost never.

Fix: bring the phone within a meter or so of the device you’re tethering. Once connected, you usually have a couple of meters of slack before signal degrades, but the initial pairing wants short range.

The “Personal Hotspot” name shows up on iOS, but Wi-Fi is off on the connecting device

Sometimes a Mac will detect Personal Hotspot via Bluetooth (Instant Hotspot) without showing it in the Wi-Fi list at all. Open the Wi-Fi menu and look under “Personal Hotspot” rather than the regular network list.

C. Connected, but no internet

The most frustrating failure: your laptop says it’s on the network, but pages won’t load. Three causes account for nearly all of these.

Cellular signal is weak where you are

Personal Hotspot needs an actual cellular connection to share. If your iPhone has one or two bars of LTE, the hotspot will technically “work” but everything you load through it will time out.

Fix: check the cellular signal indicator on your iPhone. If it’s weak, move closer to a window, step outside, or accept that the hotspot speed is going to be slow. No app or setting fixes a weak cellular signal.

Your iPhone is on Wi-Fi instead of cellular

If your iPhone is connected to a Wi-Fi network (a café, an airport, your home Wi-Fi), the hotspot may try to share that Wi-Fi connection instead of cellular. Wi-Fi-to-Wi-Fi tethering has poor reliability and is often the actual root cause when “Personal Hotspot says connected but nothing loads.”

Fix: turn off Wi-Fi on your iPhone temporarily and force the hotspot to share cellular data instead.

Carrier is throttling hotspot traffic

Some carriers cap hotspot speed dramatically once you’ve used your monthly tethering allowance. Visible (US) drops to 5 Mbps after 5 GB. T-Mobile postpaid throttles to 2G speeds after the hotspot cap. AT&T behaves similarly.

Fix: check your plan’s hotspot cap and current usage in the carrier app. If you’ve hit the cap, the only real options are to upgrade the plan or wait for the next billing cycle.

D. Works for a few minutes, then drops

This is the most-reported and least-understood hotspot failure on iPhone. You connect, everything works, you set the phone down to grab coffee, and 30 seconds later your laptop loses the network.

The cause: iOS aggressively powers down the cellular radio when the phone goes idle, to save battery. The hotspot drops within seconds of the iPhone screen turning off.

Things that don’t fix it:

• Toggling the hotspot off and on (works for 30 seconds, then drops again)
• Resetting network settings (changes nothing about the radio sleep behavior)
• Updating iOS (the behavior has been in place since iOS 14)
• Turning off Low Power Mode (helps marginally but doesn’t solve it)
• Maximizing Compatibility (changes the Wi-Fi band, not the radio sleep)

Things that do fix it:

• Setting Auto-Lock to Never: works as long as your screen stays on. Costs your battery and burns in the OLED panel. Workable for short sessions, painful for long ones.
• Keeping Settings → Personal Hotspot open in the foreground: works while it’s the active screen. The moment you switch apps, you’re back to dropping.
• An app that uses background location updates to keep the radio awake. This is the only fix that lets you lock the phone and walk away. We built Hotspot Hero around exactly this mechanism.

The full technical breakdown of why settings tweaks all hit a ceiling is in our piece on the disconnection problem. The short version: the cellular radio sleep happens at a layer below user-visible settings, and Location: Always is the only Apple-sanctioned API that keeps it awake.

Frequently asked questions

Why does my mobile hotspot say connected but no internet?

Three causes account for almost all of these. Your iPhone has weak cellular signal (the hotspot is “on” but has nothing to share), your iPhone is tethering from a Wi-Fi network rather than cellular (unreliable), or your carrier has throttled your hotspot speed because you exceeded the monthly cap. Check cellular signal first, turn off Wi-Fi on the phone if needed, then check your plan’s hotspot usage in the carrier app.

How do I fix mobile hotspot on iPhone?

The fix depends on the specific failure. If it won’t turn on, work through the seven causes in our greyed-out guide. If it connects but drops, that’s a different problem with a different fix, covered in our disconnection piece. If devices can’t see it, toggle Maximize Compatibility on. If it connects but no internet loads, check cellular signal.

Why does my mobile hotspot keep turning off?

Because iOS powers down the cellular radio when the phone is idle, to save battery. The hotspot drops within seconds of the screen turning off. The only reliable fix is an app that uses background location updates to keep the radio responsive. Auto-Lock to Never works too, but burns through battery and risks display burn-in.

Will resetting network settings fix mobile hotspot?

Sometimes. Reset Network Settings clears a class of network configuration glitches that can keep Personal Hotspot from turning on, especially after a botched iOS update or eSIM transfer. It does not fix the radio sleep that causes hotspots to drop every few minutes. It will erase saved Wi-Fi passwords, so have them ready.

Is mobile hotspot different from tethering?

In practice, no. “Personal Hotspot” is Apple’s name, “Mobile Hotspot” is Android’s name, and “tethering” is the generic term that includes both. Tethering can be Wi-Fi (most common), Bluetooth, or USB. The underlying behavior and most of the failure modes are the same across all three.

When to stop troubleshooting {.no-faq}

If you’ve worked through the relevant section above and your hotspot still won’t work, the cause is almost certainly carrier-side: a plan that doesn’t include tethering, a corrupted carrier profile, or local network conditions. Call your carrier, tell them what you’ve already tried, and ask them to push a refreshed carrier profile. If the issue is specifically the connection dropping after a few minutes, you’ve hit the radio sleep and that’s a different problem with a specific fix.
