How many devices can share my hotspot?
The maximum is set by your phone rather than the plan, and it varies by model. In practice, the more devices attached, the less speed each gets and the faster the battery drains. For long sharing sessions, keep the phone on charge.
This question tends to come up while planning a trip with friends or family, when someone suggests buying one eSIM and sharing its hotspot across everyone rather than buying a separate plan for each person. The follow-up questions are practical: how many devices can share it, how much does speed drop, and how much faster does the battery drain. This page explains what actually sets the number of devices that can share a hotspot, what happens to speed and battery once several devices attach, and the points where hotspot sharing commonly gets misunderstood.
It suits groups of friends or family deciding between one shared eSIM and separate plans for each person, anyone who has shared a hotspot before and found the connection dropped off far more than expected, and anyone wondering whether a tablet or laptop can attach normally to an eSIM phone's hotspot. Everything here covers general principles of mobile hotspots, not a fixed device count or speed figure, since those depend on the phone model, its operating system, and the network operator involved in each country.
Why the limit belongs to the phone, not the plan
The hotspot, or personal hotspot, feature is a function of the phone's own operating system, not something a data plan switches on or off. An eSIM plan only supplies data volume and a network connection — the number of devices that can attach at once is set by that specific phone's own hardware and software.
That means two phones running the exact same eSIM plan can support different numbers of shared devices if they're different models or different operating system versions, because the limit is tied to that individual phone rather than any entitlement the plan grants.
How to check your own phone's limit
We can't state a maximum device count that applies across every model, since each brand and each operating system version sets this differently. The reliable way to find out is opening the hotspot settings page on your own phone, since many models display the maximum supported count right alongside the hotspot on/off switch itself.
If no figure is shown on the settings page, try searching 'hotspot', 'personal hotspot', or 'tethering' in the settings app's search box, since on some models the menu sits under a general connections section rather than directly under mobile network settings.
How the number of connected devices affects speed
The data flowing through a hotspot at any moment is shared across every device using it at once, not multiplied for each additional one. The more devices attached and the harder they're being used at the same time, the less speed each one gets, particularly if several are streaming video or downloading large files simultaneously.
The phone broadcasting the hotspot keeps using its own internet connection as normal too, which means if its owner is running a heavy app at the same time as sharing with others, speed for everyone in the group is affected together, not just the devices that joined in.
Why battery drains faster with more devices sharing
Broadcasting a hotspot already keeps a phone's radio and Wi-Fi circuitry working harder than usual, since it has to keep sending and receiving data for other devices for as long as the connection stays open. The more devices connected and the heavier the data traffic, the harder the phone has to work, which drains the battery faster than simply using its own connection normally.
Does sharing draw from the same data as the host phone
The data other devices use through the hotspot draws from the exact same data allowance the eSIM plan gave that one phone — no separate quota gets created for hotspot sharing. So the more devices sharing and the harder they use it, the faster the plan's overall data allowance gets used up.
If planning to share a hotspot with several people across a whole trip, it's worth estimating everyone's combined data use in advance rather than just what the phone's owner alone would normally use, since actual consumption runs considerably higher once other people are attaching too.
Setting a hotspot password sensibly while travelling
Most phones set an automatic hotspot password from the start, but it's worth changing it to something you set yourself and haven't used elsewhere before, particularly when sharing in a public place such as a restaurant or a train station, to reduce the odds of a stranger guessing it and joining without permission.
If an unfamiliar device seems to be attached, open the connected-devices list on the hotspot settings page, since many phones show the names or count of devices currently joined, making it possible to disconnect an unrecognised one right away.
Sharing one phone versus each traveller having a separate eSIM
| Aspect | Sharing one hotspot | A separate eSIM for each traveller |
|---|---|---|
| Speed per person | Drops as more people attach at once | Each person uses their own signal, unshared |
| Battery | The broadcasting phone drains faster than normal | Each phone drains at its own normal rate |
| Need to stay close together | Must stay within that phone's Wi-Fi range | Each person connects to the mobile network independently |
Comparing the two approaches for a travelling group
How much distance from the broadcasting phone matters
A phone's hotspot broadcasts over short-range Wi-Fi, much like an ordinary Wi-Fi router. The further a connected device sits from the broadcasting phone, or the more obstacles such as thick walls sit in between, the weaker the signal and the slower the resulting speed, regardless of how much data the plan still has left.
For a group walking together, keeping the broadcasting phone in the bag or hand of whoever is walking roughly in the middle of the group tends to keep the signal reaching everyone more evenly, compared with leaving it with someone walking well ahead of or behind the rest.
What affects overall hotspot performance
| Factor | What it changes |
|---|---|
| Number of devices connected at once | More devices means less data throughput and speed for each one |
| Distance from the broadcasting phone | Further away or more obstacles weakens the Wi-Fi signal |
| Battery-saving mode on the broadcasting phone | Some models automatically cap mobile speed while this is active |
| The mobile signal the host phone itself receives at that spot | The hotspot can only pass on speed as good as what the host itself is receiving |
Worth checking before concluding the hotspot itself is at fault
Can a tablet or laptop connect through the hotspot normally
Any device that supports ordinary Wi-Fi, whether a tablet, a laptop, or even a camera with a Wi-Fi function, connects through a phone's hotspot on the same principle as another phone would, since the hotspot treats every connected device the same way as it shares out signal — it doesn't distinguish between device types.
What's different is that laptops and tablets tend to use more data during ordinary background activity, such as operating system updates or syncing large files. If connecting this kind of device through a hotspot, it's worth turning off automatic updates or background syncing beforehand, so the plan's data isn't used up on something unintended.
If the broadcasting phone needs restarting mid-trip
Restarting the phone, whether to fix a glitch or after a software update, switches the hotspot off automatically along with it, and every other device that was connected drops off immediately. Once the phone comes back on, the hotspot has to be switched back on manually again — the system won't turn it back on by itself even though it had been left running before.
If relying on the hotspot for something continuous, such as navigation while driving, it's worth telling the rest of the group in advance that the phone might need restarting occasionally, so nobody is caught off guard if the connection drops suddenly with no obvious network-side reason.
Does airplane mode work alongside the hotspot
Airplane mode switches off all mobile network and Wi-Fi connections by default, including the hotspot. Some phones let Wi-Fi be turned back on separately after airplane mode is on, but the mobile network connection the hotspot needs to pull internet from in the first place stays off, which means the hotspot genuinely won't work in that state.
If a hotspot is needed while on transport that requires airplane mode, always follow that carrier's own instructions first, since safety rules set by each airline or operator take priority over any wish to keep a hotspot connection running continuously.
Planning charging across several consecutive days of sharing
If a trip involves several consecutive days of hotspot sharing, it's worth setting a clear charging window for the broadcasting phone each day, such as charging it fully during a hotel stop before heading out, rather than waiting until the battery is nearly gone before hunting for somewhere to charge, since sustained sharing drains the battery much faster than usual.
Rotating who carries the broadcasting phone each day is another way to spread the battery burden rather than it always falling on the same device throughout the trip, particularly if everyone in the group already has their own eSIM line and just wants to take turns sharing occasionally, rather than relying on one phone the whole time.
How the hotspot relates to the eSIM line's own roaming
The hotspot's only job is passing along whatever internet connection the phone already has to other devices — it doesn't create a new connection of its own. So if the eSIM line in use has no signal, or its data plan has already run out, the hotspot has nothing left to pass on, no matter how correctly it's been set up.
Before suspecting the hotspot itself, it's worth checking whether the phone can use the internet normally on its own, for instance by opening a web page directly on that device. If the host phone itself has no working connection, the problem sits with the signal at the source, not with the sharing feature itself.
Setting expectations with the group beforehand
If the decision is to share one hotspot across the group rather than buying separate plans, it helps to explain to everyone up front that speed will drop when several people use it heavily at once, and that the broadcasting phone will need charging more often than usual, so nobody's expectations end up mismatched with what actually happens mid-trip.
Agreeing in advance who carries the broadcasting phone during each part of the day, and who's responsible for bringing a spare charging cable, also cuts down on confusion mid-trip considerably, especially in a larger group that often splits up while out and about.
Common reasons a device won't connect even under the limit
Many phones automatically switch off the hotspot after a period with no device connected, to save battery. If another device drops off without anyone noticing, the hotspot may already have switched itself off with nobody having deliberately turned it off, so nothing else can rejoin until it's manually switched back on.
Another frequent cause is a mistyped password, especially when the password contains similar-looking characters, such as a zero versus the letter O, or a one versus a lowercase l. It's worth double-checking the password carefully before concluding the hotspot or the device limit itself is the problem.
- 1Turn on the hotspot from the eSIM line you want to shareGo to the hotspot settings page and select the eSIM line carrying the active plan, not a line with no data plan switched on.
- 2Set a password that hasn't been used elsewhereChange the hotspot password to one you set yourself before sharing it with anyone, especially if sharing happens in a public place.
- 3Connect only the devices you actually needAttach only the devices actually needed at that time, rather than leaving every device in the group connected all day.
- 4Keep the broadcasting phone on charge for long sessionsIf a long sharing session is expected, keep the cable plugged in from the start rather than waiting until the battery is nearly gone.
- 5Disconnect devices that are finished using itDisconnect devices once they're done, or check how many are currently attached if the connection suddenly feels much slower than expected.
- A hotspot password set fresh, not reused from elsewhere
- A charging cable and backup charger for the broadcasting phone
- Knowing which eSIM line actually has an active data plan
- Understanding that more devices means less speed and faster battery drain
- Knowing where the hotspot menu sits on your own phone in advance

Does eSIMonline set a maximum number of devices for sharing?+
No. The limit comes from the phone broadcasting the hotspot itself, not from the data plan.
Does connecting more devices slow down the host phone's own browsing too?+
It can, since the available data is shared across everything using it at once, including the phone doing the broadcasting.
Does sharing a hotspot use extra data beyond what the plan already includes?+
No separate allowance is created. Sharing draws from the same data pool the plan already gives that phone.
A device won't connect even though the group hasn't reached the phone's supported count — what to check first?+
Double-check the password first, then see whether the hotspot switched itself off after sitting with nothing connected for a while, or because a battery saver is active.
Is it better to share one phone, or should everyone in the group have their own eSIM?+
It depends on the group's needs. Separate eSIMs give each person their own unshared signal, while sharing one phone saves on the number of plans bought but requires staying close together and accepting reduced speed as more devices attach.
Can a data cap be set for each individual device connected to a hotspot?+
That depends on the broadcasting phone's own features and operating system, not something an eSIM plan controls. Check that specific phone's own settings for whether such a feature exists.
