How many eSIMs
does a family actually need?
Not one per person. Every page ranking for this today is an eSIM vendor's own blog, which means it is written to sell you more data plans, not to answer the question honestly. Here is what we actually run across two adults and two kids.
Kids do not need their own plan.
Kids traveling with parents do not need their own eSIM. They use a parent's phone directly, or connect to a personal hotspot when they need a device of their own for a show or a game. What actually matters is which phone or phones hold a working data plan, not how many people are on the trip.
Usually one eSIM is enough.
If the family stays together for most of the day, one phone with a working data plan can cover navigation, translation and messaging for the whole group, with the second adult's phone left on WiFi-only or airplane mode to save the cost of a second plan. The exception is any day the family splits up, one adult with the kids at a playground while the other runs an errand, for example. On those days, a second eSIM is worth it so both adults have maps and messaging independently rather than relying on being back in range of each other.
A physical SIM card, entirely.
Switching to an eSIM through Airalo replaced buying and swapping physical SIM cards for us completely. The advantage is timing: it gets set up at home, before the trip even starts, so it switches on the moment the plane lands instead of leaving you hunting for a SIM kiosk at an unfamiliar airport with jet-lagged kids in tow. Airports generally have WiFi. The taxi rank and the walk to your apartment usually do not, and that gap is exactly where an eSIM set up in advance earns its cost.
Set it up before you leave so it switches on the moment you land. This has replaced physical SIMs for us entirely and it is the cheapest peace of mind on our packing list.

What families ask us.
Does every family member need their own eSIM in Europe?
No. Kids traveling with parents generally do not need their own data plan; they use the parents' phones or connect to a personal hotspot. What matters is which phone or phones actually hold a working data plan, not how many people are in the group.
How many eSIMs do two parents need?
In most cases, one is enough if the family stays together most of the day, with the second adult's phone on airplane mode or WiFi-only to save cost. If the family splits up for part of a trip, a second eSIM on the other adult's phone is worth it so both of you have maps and messaging independently.
What did an eSIM replace for your family?
A physical SIM card. Switching to Airalo replaced buying and swapping physical SIM cards entirely for us. It is set up before you leave home so it switches on the moment you land, rather than hunting for a SIM kiosk at an unfamiliar airport.
Should you set up the eSIM before or after landing?
Before you leave home. Airports have WiFi, but the taxi rank, the train platform and the walk to your apartment usually do not. Getting the eSIM installed and ready before departure means it switches on the moment you land instead of leaving you without maps or messaging for the first stretch of the trip.
