A solo traveler has only one device to manage and, almost always, a single goal: staying connected to navigate, check maps, share a few photos. A traveling family, on the other hand, multiplies the variables: several smartphones of different ages and operating systems, tablets to entertain the kids during transfers, and often a laptop for whoever can never fully switch off from work.

On top of this comes a factor that's often overlooked: a family rarely moves as a single unit for the whole day. Kids may join separate activities, one parent might stay at the hotel while the other goes out with the children, and older kids want their own independence. Every split, even a brief one, is a moment when shared connectivity might not be enough.

Just take a quick inventory to see how many devices are involved: two parents' smartphones, one or more smartphones for older kids, one or two tablets for entertainment during long transfers, often a laptop for whoever works even on vacation, and sometimes a smartwatch to keep updated.

A family of four easily reaches 5-7 devices that, one way or another, will need mobile data during the stay abroad: for navigating, communicating, translating a menu, booking a table, or simply keeping the little ones occupied during a long flight.

It's not necessarily an "either/or" choice: most families get the best result by combining both strategies. One or two eSIMs with hotspot can cover secondary devices (kids' tablets, an occasional laptop), while smartphones that might move away from the group — a teenager's phone, or a parent's phone when going out alone with a child — benefit from their own independent connection.

The question to ask yourself isn't "which solution is best overall", but "which devices, on this specific trip, risk being left without a connection if they depend on someone else's hotspot".

Hotspot (or "tethering") is the feature that turns the smartphone with the eSIM installed into a small router: the phone shares its own data connection with other nearby devices via a local Wi-Fi network, exactly as you would already do at home with your regular SIM.

With a BLIVALE travel eSIM that includes hotspot, you simply turn on the option in the phone's settings, set a password for the shared network, and connect tablets, laptops, or other family members' smartphones to that network. No extra app, no extra physical device: the phone you already carry in your pocket becomes the access point for the whole family.

The most immediate benefit is financial: instead of buying an eSIM for every single device, one single data plan with hotspot can power several devices at once, noticeably reducing the overall connectivity cost for the whole family.

The second benefit is practical: the kids' tablet doesn't need its own eSIM (many budget tablets don't even support one), yet it can still access YouTube, maps, or online games during transfers, simply by connecting to a parent's phone hotspot.

The third benefit is about management: just one plan to monitor, one data usage to keep an eye on, instead of handling activations, QR codes, and different expiry dates for every family member.

On data usage, the answer is simple: hotspot doesn't "waste" data on its own — the data traffic generated by connected devices (video streaming, maps, messaging) simply adds up and is counted against the plan of the phone sharing the connection. That's why, if you expect heavy hotspot use from multiple devices at once, it's worth choosing a plan with generous or truly unlimited data.

On the battery side, keeping hotspot active does use more power than normal phone use, because the device has to manage both the mobile data connection and the local Wi-Fi network it generates. It's fully manageable with a power bank or by recharging the phone during downtime (car, hotel, restaurant), but it's something to factor in when planning a full day of excursions.

The good news is that hotspot isn't a feature reserved for a few premium plans: it's designed exactly for people traveling with multiple devices, like families.

For families with young children who almost always stay with the group, a single eSIM with hotspot activated on one parent's phone is often enough and represents the most cost-effective solution: one data plan powers tablets and secondary devices, while the second parent's smartphone can either join the same shared hotspot or have its own backup eSIM.

For families with teenagers or kids who move around independently — an afternoon in town without the parents, a separate excursion — it's better to equip every smartphone that might move away from the group with its own independent eSIM, so you never lose the ability to stay in touch.

Many budget tablets or handheld consoles don't support eSIM, but that's not a problem: they can still get online by connecting to a parent's smartphone hotspot, with no dedicated activation needed.

For newer tablets that do support eSIM, a dedicated eSIM is worth considering only if the device is often used on its own, away from the parent's phone generating the hotspot: for example, if a child brings their own tablet to a summer camp or a separate activity from the rest of the family.

Usage depends a lot on habits, but when several devices rely on the same hotspot, the total adds up quickly: maps and navigation use little data, while video streaming, video calls, and online games to entertain the kids during transfers can significantly increase daily usage.

That's exactly why, when hotspot needs to serve several people at once, it's worth choosing plans with high data thresholds or truly unlimited data with no FUP (Fair Usage Policy), to avoid ending up with a slowed-down connection right on the days of heaviest use, like during a long car or train transfer.

The process is identical for every family member: you buy an eSIM for each device that needs one, receive a dedicated QR code for each, and install it directly from the settings of the compatible phone, tablet, or laptop — even before departure, comfortably from home.

A practical tip for families: activate all the eSIMs a few days before the trip, so you can check that every device has installed them correctly, without having to troubleshoot technical issues on departure day itself, perhaps at the airport with luggage to handle and tired kids.

It's not a dealbreaker: simply connect that device to the hotspot of a smartphone that does have an active eSIM. This is exactly the scenario where hotspot proves its full value for a family with devices of different generations and ages.

Before departure, it's still worth checking eSIM compatibility for every smartphone (on most recent models it's found in settings, under the SIM section), so you know in advance which devices will have their own connection and which will need to rely on another family member's hotspot.

• Map out your devices before leaving: count how many smartphones, tablets, and laptops will travel with you, and decide together which ones will have their own eSIM and which will rely on hotspot.

• Activate everything in advance: install the eSIMs from home, not at the last minute at the airport.

• Choose plans with no FUP if you plan to use hotspot heavily with multiple devices connected for hours.

• Bring a power bank: hotspot uses more battery than normal, and within a family the phone with hotspot turned on is often the most precious device of all.

• Save the hotspot network password on all the kids' devices before departure, so you don't have to retype it every time on the go.
