An eSIM (embedded SIM) is a digital SIM card built into the phone or tablet: it's not a piece of plastic to insert into a tray, but a profile installed by scanning a QR code or through a dedicated app.

With BLIVALE the process takes just a few minutes, often from home before departure: you choose the data plan for your destination, receive the QR code, scan it, and the eSIM is ready to activate as soon as you land. No courier, no store to find abroad, no extra device to pack.

Pocket Wi-Fi, also called MiFi or a portable hotspot, is a small physical device — about the size of a deck of cards — that contains a SIM (physical or built-in eSIM inside the router) and turns a mobile data connection into a local Wi-Fi network.

You switch it on, connect your smartphone, tablet or laptop just as you would to your home Wi-Fi, and every device shares the same data connection. It needs to be rented (or bought) before departure, picked up at the airport or received by courier, charged every day, and returned once you're back.

With an eSIM, every device has its own independent connection: your phone gets online on its own, without depending on another device being switched on, charged and within Wi-Fi range.

With Pocket Wi-Fi, on the other hand, every device depends on a single "hub": if the router runs out of battery, gets switched off, or is left in the hotel room while you're out and about, every connected device loses signal at the same time.

It's the difference between an individual connection and a shared connection: the first is simpler to manage on your own, the second makes sense when the connection genuinely needs to be split between several people or devices.

Renting a Pocket Wi-Fi usually comes with a fixed daily cost, regardless of how much data you actually use, plus often a deposit (refunded on return, if the device comes back undamaged) and, in some cases, shipping costs.

The daily cost may look modest if split between several people in the group, but it always has to be multiplied by the entire length of the trip — including the days the router might just sit switched off in a bag.

With a BLIVALE eSIM you only pay for the data plan you need for yourself: no deposit, no shipping, no cost for managing a physical device.

For a solo traveler, the comparison is almost always in favor of the eSIM: similar budget, but without the financial risk tied to a deposit and without having to "spread" the cost of a router over just one user. For a larger group the math changes, since the Pocket Wi-Fi cost is split between more people — we'll look at that in detail further on.

Yes, and it's one of the aspects users often discover only after the trip is over. The most common items to watch out for are:

• Deposit: held on your card at rental time, refunded only if the device comes back working and within the agreed deadline.

• Shipping: some providers include it, others charge it separately for outbound and return.

• Late-return penalty: if your return flight is delayed and you hand the router back a day late, you'll almost always pay an extra penalty.

• Damage or loss penalty: if the router is broken, gets wet, or is never returned, the cost can reach the full commercial value of the device.

Pocket Wi-Fi is worth it when its daily cost is genuinely split between several people traveling together who share the same room or the same means of transport for most of the day: a group of friends in a van, a family that always moves as a unit, a work crew.

In these scenarios, the per-person cost of the router can be competitive compared to buying an eSIM for each member of the group. The economic advantage shrinks — or disappears — as soon as the group splits up during the day, because at that point only whoever is carrying the router stays connected.

An eSIM is designed for one device at a time: the phone or tablet it's installed on. Some data plans still let you share the connection with other devices via personal hotspot, exactly like you would with your home SIM.

A Pocket Wi-Fi, on the other hand, is designed precisely for sharing: on average it supports 5 to 10 devices connected at the same time, which makes it handy when an entire group needs to get online together without installing anything on individual phones.

This is one of the most concrete, and most underestimated, risks of renting: a physical device can fall, get wet, be stolen along with your bag, or simply get left behind in a nightstand drawer at your last hotel.

In all these cases the rental provider applies a penalty, which in most contracts corresponds to the full commercial value of the device — an unpleasant surprise on top of the stress already present at the end of a trip.

With an eSIM this risk simply doesn't exist: there's no physical object to return, so there's nothing to lose, break, or forget.

No: the eSIM lives inside the phone you already carry, so its battery life is simply your smartphone's. It adds no meaningful extra battery drain and requires no separate management.

Pocket Wi-Fi, on the other hand, has its own battery with a typical life of 8-12 hours of continuous use: it therefore needs charging every day, meaning you'll carry a cable and, often, a dedicated charger or power bank — one more thing to think about during the trip.

For a solo traveler, even with two devices in tow, the eSIM remains almost always the simpler and more cost-effective choice: activate the data plan on your phone and share the connection to your laptop via hotspot whenever needed, without carrying or managing any extra device.

Pocket Wi-Fi in this scenario adds one more object to charge, look after and return, with no real advantage in terms of connected devices: an eSIM with hotspot covers the same need with far less hassle.

Here the answer depends on how much the group actually stays together during the day. If a family or group always moves as one — same car, same itinerary, same room — a shared Pocket Wi-Fi can be economical, since its cost is split among everyone.

If the group splits up often — kids at school or on an excursion, partners in different meetings, friends visiting different places on the same day — each person needs their own independent connection: in this case an eSIM for every device removes the risk of being "cut off" every time you move away from whoever is carrying the router.

Ask yourself two quick questions:

• Are you traveling solo, as a couple, or does your group often split up during the day? → An eSIM for each device is simpler, requires no extra object to manage, and never leaves you dependent on another device being switched on.

• Are you traveling as a large group that always stays together and wants to split a single cost? → Pocket Wi-Fi can make sense, as long as you accept the deposit, return and daily charging involved.
