Let's start with something you already know: a WiFi hotspot.
What You Already Know
A WiFi hotspot is a device (or your phone's personal hotspot feature) that creates a WiFi network using cellular data. You've used one. You understand it. It gives your devices internet access when there's no WiFi around.
What an eSIM Is
An eSIM does the same thing — but instead of a separate device or your existing plan, it's a separate data plan installed directly on your phone. Think of it as a second SIM card, but digital (no physical card required).
When your child is in Italy, their eSIM gives their phone Italian internet access. Their US phone number still works for calls and texts. The eSIM just handles the data.
The Hotspot vs. eSIM Comparison

Why This Matters for Your Child's Study Abroad
Without an eSIM (or local SIM), your child either:
a) Pays $10-15/day in carrier roaming fees ($300-450/month)
b) Relies entirely on WiFi (which isn't always available or reliable)
With an eSIM, they have reliable internet access for $0.30-$1.50/day — and you can reach them anytime.
The Bottom Line
If their phone supports eSIM (iPhone XR or newer), this is the obvious choice. It's cheaper, simpler, and more reliable than any alternative.
