Quick fix when hotspot is not working
First, restart the phone sharing data, not just the hotspot. If that doesn't solve anything, check in this order: mobile data activated, data plan with available balance, correct APN, and hotspot password correctly entered on the other device. In most cases, the problem is solved in one of these four steps.
This article follows the same order: from the most probable cause to the least probable. You don't need to read the whole thing, just scroll down until you find your case. If you are traveling and the problem is that your carrier blocks data roaming (something very common and that cannot be fixed from the phone settings), we explain it in section 8, with the alternative that does depend on you.
Step 1: Restart the hotspot and the connecting device
Turning the hotspot off and on resolves a significant portion of cases because it clears the radio connection between the phone and the carrier's network, which sometimes gets "stuck" without showing any visible errors. But restarting only the hotspot is not always enough: the device trying to connect (a laptop, a tablet, another phone) also caches the WiFi network you created, and if that cache is corrupted, it will continue to fail even if the hotspot works perfectly.
The order that avoids wasting time with partial attempts is this: completely turn off the phone that is sharing data (not just airplane mode), wait about 10 seconds, turn it back on, and reactivate the hotspot. Then, on the connecting device, forget the hotspot's WiFi network (don't just disconnect it) and search for it again from scratch. This forces both devices to negotiate the connection again instead of reusing saved data that might be corrupted.
If you use an iPhone, there's a detail that almost no one checks: the hotspot name only changes if you changed the phone name in Settings > General > About, and some older devices still look for the old name in the list of saved networks. If your hotspot "disappeared" from the list of available WiFi networks on another device, that's a common suspect before thinking something is broken.
Step 2: Check that mobile data and hotspot are activated
Why can't I activate the hotspot? Almost always because the phone's mobile data is turned off separately from the hotspot switch: these are two different settings, and one depends on the other. If mobile data is deactivated, the hotspot may appear "on" on the screen but it will not share anything at all, because it has no connection to draw from.
On Android, this is checked in Settings > Network & internet > Mobile network, and separately in Settings > Hotspot & tethering (the exact name varies by phone brand). On iPhone, it's in Settings > Mobile Data and, below that, Settings > Personal Hotspot. The most common trap is having the hotspot activated but mobile data turned off, something that often happens unintentionally after activating and deactivating airplane mode, because some phones do not reactivate data automatically.
Another cause within this same step: some "battery saver" or "low power mode" apps pause background connections, including the hotspot, when the phone has been idle for a while. If the hotspot cuts out only when you leave the phone still for a while but works fine as soon as you touch it, check that option before any other.
Step 3: Check if you have exhausted your data plan or fair usage limit
Because the Internet sharing option often doesn't work for a simple reason: there is no data balance left in the plan, or the plan has a specific hotspot limit that is lower than the phone's general data limit. This is different from losing signal: the phone can continue browsing fine on its own and, at the same time, not share a single megabyte via hotspot, because the operator separates both consumptions in the contracted plan.
Check data consumption from the phone settings (not from the operator's app, which sometimes takes hours to update) and compare how much you have spent against the total plan. If the plan is "unlimited," also verify if it has a fair usage policy: after a certain monthly consumption, some operators reduce the speed to levels that make the hotspot unusable, even if you are technically still "connected."
A hotspot that turns on, shows the available WiFi network, and allows the other device to connect, but doesn't load any page, is almost never a phone problem: it's a sign that the underlying data connection (exhausted balance, reduced speed due to fair use policy, or blocked roaming) is failing, not the hotspot itself.
Step 4: Check APN and mobile network settings
The APN (Access Point Name) is the setting that tells the phone how to connect to your specific carrier's data network. If the APN is wrong, empty, or corresponds to another carrier, the phone's mobile data may fail intermittently, and the hotspot with it, even if you have full signal on the screen. This happens more frequently after inserting a new SIM, factory resetting the phone, or changing carriers without restarting the device.
On Android, it's checked in Settings > Network & internet > Mobile network > Access Point Names. On iPhone, in Settings > Mobile Data > Mobile Data Options > Mobile Data Network. If you don't know the correct APN for your line, the most reliable way is to look it up directly in your carrier's app or official website, because each one uses different values and entering an incorrect one can leave you without data completely, not just without a hotspot.
With a travel eSIM, this step is usually skipped, as the profile is installed with the network configuration already integrated. If you want to understand the complete technical difference between both systems, we explain it in more detail in what is an eSIM.
Step 5: Check password, WiFi band, and connected devices
Why isn't my hotspot working even though it appears in the list of networks? Here the problem is almost always on the side of the device trying to connect, not the one sharing data. The most common causes, in order of frequency: incorrectly typed password (check capital letters and the character "1" vs. lowercase "l", a classic error), the hotspot configured in the 5GHz band when the other device only supports 2.4GHz, or the maximum limit of simultaneously connected devices already reached.
The 5GHz band offers higher speed but has less range, and not all older devices recognize it; if your laptop sees other WiFi networks but not your hotspot, try changing the band to 2.4GHz from the hotspot settings. Regarding the device limit: most phones allow between 5 and 10 simultaneous connections per hotspot, and if you're traveling in a group sharing a single phone, it's easy to reach that limit without realizing it.
How to restart a hotspot on Android and iPhone, step by step
A complete restart (not just turning the hotspot switch off and on) is the step most often skipped because it seems redundant, and it's precisely the one that resolves cases where there are no misconfigured settings, just a stuck internal process.
| Step | Android | iPhone |
|---|---|---|
| 1. Deactivate hotspot | Settings > Hotspot & tethering > deactivate | Settings > Personal Hotspot > deactivate |
| 2. Activate airplane mode | Swipe down quick settings panel > airplane mode | Control Center > airplane mode |
| 3. Wait | 15-20 seconds | 15-20 seconds |
| 4. Deactivate airplane mode | Swipe down quick settings panel > airplane mode | Control Center > airplane mode |
| 5. Confirm mobile data is active | Settings > Network & internet > Mobile network | Settings > Mobile Data |
| 6. Activate hotspot again | Settings > Hotspot & tethering > activate | Settings > Personal Hotspot > activate |
| 7. Forget and search for the network again on the other device | WiFi Settings > forget network > search again | WiFi Settings > forget network > search again |
If after these seven steps the hotspot still doesn't share data but the phone browses fine on its own, the problem is no longer with the hotspot as a function: it's with the data plan, APN, or carrier. Go back to steps 3 and 5 before assuming the phone has a hardware failure.
When the problem is not your phone, but the provider's roaming
There's one case that no restart can fix: you travel to another country, your phone shows signal and even allows calls, but the hotspot (and sometimes mobile data in general) simply doesn't connect to the internet. This is usually the originating carrier blocking or limiting data roaming in that specific country, something decided by the carrier, not a setting you can change from your phone.
The way to distinguish it from a technical problem of your own is simple: if data works in your country but stops working only when you arrive in another (even if the APN, plan, and all settings are correct), it's blocked or restricted roaming, not a hotspot failure. We expand on this difference, with more specific cases, in eSIM vs roaming.
When the block comes from the carrier, the solution is not to keep trying phone settings: it's to have a second data path that doesn't depend on that carrier. A travel eSIM installs in minutes on the same phone, without removing the physical SIM, and provides local or international data without depending on roaming from your original line. You can see the available plans by destination in the international eSIM collection.
Summary table: probable cause, solution, and estimated time
To quickly refer back to this article without rereading everything, here is a summary of the nine most common causes in the order they should be checked.
| Probable cause | Solution | Estimated time |
|---|---|---|
| Stuck radio connection | Full phone restart (not just the hotspot) | 1-2 minutes |
| Mobile data turned off separately from hotspot | Activate mobile data and hotspot as two distinct settings | 30 seconds |
| Battery saver pausing the hotspot | Deactivate low power mode while using the hotspot | 30 seconds |
| Data plan exhausted | Check consumption from phone settings, not carrier app | 1 minute |
| Fair use limit reached | Confirm with carrier if "unlimited" plan reduces speed | Variable |
| APN misconfigured | Re-enter the correct carrier APN | 2-3 minutes |
| Incompatible password or WiFi band | Check password and try 2.4GHz band | 1 minute |
| Device connection limit reached | Disconnect unused devices | 30 seconds |
| Roaming blocked by carrier at destination | Use a travel eSIM independent of the originating carrier | Activation in ~1 minute |
If you've reached this table and none of the first eight points apply to your case, it's most likely the last one: a roaming block that doesn't depend on your phone or its settings.
Frequently asked questions
How to restart a mobile hotspot?
Deactivate the hotspot, activate airplane mode for about 15-20 seconds, deactivate it, confirm that mobile data is on, and reactivate the hotspot. On the connecting device, forget the WiFi network and search for it again instead of just reconnecting. This complete restart resolves most cases where there are no misconfigured settings.
Why isn't the Internet sharing option working even though I have a signal?
Because having a signal and having available data balance for a hotspot are two different things. Some plans specifically limit hotspot consumption even if the rest of the phone's data works normally, and "unlimited" plans can reduce speed after a certain consumption due to a fair use policy, leaving the hotspot technically connected but unusable.
Why can't I activate the hotspot from the settings?
The most common cause is having mobile data deactivated: the hotspot and mobile data are two separate switches, and the hotspot needs mobile data to be turned on first. It can also happen if the carrier restricts the hotspot in your specific plan; in that case, the setting may appear blocked or simply not share data even if activated.
Why isn't my hotspot working even though it appears in the WiFi network list?
It's almost always due to an incorrectly typed password, an incompatible WiFi band (5GHz on a device that only reads 2.4GHz), or the maximum limit of simultaneously connected devices already reached. The fact that the network is visible only confirms that the hotspot is on, not that the data connection behind it is working.
Does the hotspot consume more battery than using data normally?
Yes, because the phone keeps the WiFi radio active in addition to the mobile data connection, and transmits that signal constantly while the hotspot is on. If you're going to use it for an extended period, it's advisable to have the phone connected to a charger or a power bank on hand.
Can I use the hotspot with a travel eSIM instead of my carrier's SIM?
Yes. A data eSIM works just like any other data line for hotspot purposes: you activate the eSIM profile, activate mobile data on that line, and activate the hotspot as usual. It's the most direct way to avoid blocked roaming from the originating carrier without changing phones or numbers.
Why does the hotspot disconnect itself after a few minutes?
Many Android phones automatically turn off the hotspot if a period passes without any connected devices, as a battery-saving measure. If it fails again right after a period of inactivity, check that timer option in the hotspot settings before looking for a more complex cause.
Do I need to restart my home router if the problem is my cell phone's hotspot?
No, these are two different systems. Your cell phone's hotspot uses your mobile carrier's data network, not your home Wi-Fi connection, so restarting your router will have no effect on a failing hotspot. If you confuse the two systems when diagnosing, you'll end up checking something unrelated to the actual problem.
Conclusion and what to do if none of this works
In order: perform a full restart, confirm mobile data is activated, check your plan and fair usage policy, correct the APN if applicable, and verify the password and Wi-Fi band on the other device. These five steps will resolve the vast majority of cases where the hotspot stops sharing data.
If after checking all of this the problem persists only when you travel to another country, it's not your cell phone: it's the carrier blocking or limiting data roaming in that destination, and no phone adjustment will fix it. For these cases, a travel eSIM gives you an independent data line that activates in approximately 1 minute and doesn't rely on your home carrier's roaming; you have 180 days from purchase to activate it, so you can have it ready before your trip without rush. If the problem appears in the middle of a trip, 24/7 support via email and WhatsApp in all languages is available to review the specific case, something that doesn't always exist with traditional carriers.
You can see the available destinations, among more than 200, in the international eSIM collection. If your cell phone is a Samsung and you've already gone through all these steps without results, there are specific causes for that brand that we cover separately in Samsung mobile hotspot not working. And if you've never used an eSIM and want to understand how it's installed before deciding, start with how to install an eSIM or check if your phone is compatible in eSIM compatible phones.
