eSIM Hotspot: Share Your Travel Data Without Extra Fees
5 min read
Your laptop is running off your phone, so is your travel partner's tablet, and all of it comes out of one prepaid data package. That's what an eSIM hotspot is for. And almost no travel eSIM provider charges you a cent for it.
Why the eSIM hotspot usually costs nothing extra
On home phone contracts, tethering was a paid add-on for years, and on cheap tariffs it was blocked outright. Plenty of travellers still carry that expectation with them.
It doesn't hold for travel eSIMs. Airalo says in its help centre that Personal Hotspot works with the eSIM as long as your device and the network support it. Saily describes tethering as a standard feature across every plan tier.
One misconception is stubborn, though. The EU's "Roam Like At Home" rule (European Parliament) governs your home carrier's contract while you travel inside the EU. A travel eSIM is a separately purchased data product and sits outside it. Any hotspot limit you run into comes from the provider, not from Brussels. We cover the right data roaming setting for your travel eSIM in a separate guide.
Setting up the eSIM hotspot: iPhone and Android
Setting your phone up as a wifi hotspot with a travel eSIM takes less than two minutes.
On iPhone it's Settings > Personal Hotspot > "Allow Others to Join". Worth checking first under Settings > Cellular that the travel eSIM is the selected data line.
On Android: Settings > Network & Internet > Hotspot & Tethering > Wi-Fi Hotspot. Samsung calls the menu "Mobile Hotspot and Tethering".
Set a password, connect, done.
Who caps what
Here's how the eSIM hotspot works with the four biggest providers:
| Provider | Tethering allowed | Known limit |
|---|---|---|
| Airalo | yes | no hotspot cap; unlimited plans throttle to 1 Mbps after 3 GB per day |
| Saily | yes | no hotspot cap stated |
| Ubigi | yes | no hotspot cap stated |
| Holafly | yes | daily shared-data cap, amount depends on destination |
Hotspot not working? Check the data line first
According to Apple Support, Personal Hotspot on a dual-SIM iPhone only ever shares the line currently set as your cellular data connection. If your home SIM is still installed and still active, the phone dutifully shares a connection that isn't running abroad.
Two minutes in Settings > Cellular fix this more often than any restart does. Still no connection? Our guide to eSIM not working abroad covers the rest.
Is a portable Wi-Fi router worth it instead?
Four people on one trip, or a phone you'd rather not run as a transmitter all day? Then probably yes. Honestly? For two devices and a week away, a separate router is wasted money, the hotspot in your pocket does the same job without needing its own charge overnight. For when a router does pay off, see our full mobile hotspot vs. eSIM comparison. Whether it's your own eSIM hotspot or a separate device, the hotspot built into your phone covers most trips.
Frequently Asked Questions
Is an eSIM hotspot even possible?
Yes. Tethering is a normal device feature on almost every travel eSIM, not an add-on. The per-provider exceptions and daily caps are covered earlier in the article.
Does hotspot use cost extra on a travel eSIM?
No, not with any of the four providers we checked. There's no separate "hotspot allowance" billed on its own, shared data just comes out of your regular balance. Burn through your whole plan over hotspot and you're offline yourself too.
Do EU roaming rules apply to my travel eSIM?
No. "Roam Like At Home" only protects the contract you signed at home, not a separate data package you buy for the trip. That's why Holafly can set a daily cap without breaking EU law: it's simply a different product.
Why is my eSIM hotspot not working?
Usually the phone is sharing the wrong line. Under Settings > Cellular, check that the travel eSIM really is your cellular data connection. Airplane mode, a restart or APN settings come after that.
Which provider allows unlimited tethering?
Airalo, Saily and Ubigi name no hotspot cap. Airalo's unlimited plans do throttle after 3 GB per day, which hits hotspot traffic too. Holafly caps shared data per day, depending on the destination.
