Family trips: how many eSIMs a family actually needs
Not everyone needs one, but leaning on a single hotspot has costs you do not see on the receipt.

Quick answer
- At least two plans for two adults, so the whole family does not go offline together if you get separated.
- Young children who stay with an adult can ride on a hotspot.
- Teenagers who split off should carry their own.
The question is not how many people are travelling but who might end up alone. Anyone who could need to find their own way back to the hotel should have their own connection.
Split by role, not by headcount
- Whoever navigates and holds the bookings needs the most data: maps and mail run all day
- The second adult should carry their own as the backup
- Children who mostly watch on the move should download in advance rather than stream
- Older travellers who dislike settings should have theirs installed and tested at home
Hotspot sharing drains the host phone quickly. If you rely on it, carry a power bank and agree who the host is.
Sizing the family's total
The simplest method is to size for the heaviest user and add a light allowance for everyone else. A family that uses maps, sends photos to a chat group and checks in for flights uses far less than expected; video and clip uploads are where the gigabytes go.
FAQ
Can we buy one big plan and share it with everyone?+
Yes, over a hotspot if the plan allows it, but everyone drops offline together when the host runs flat or walks away.
What if a child's phone is too old for eSIM?+
Use a hotspot from a parent's phone, or download content before leaving the accommodation.
