On a family holiday, internet access isn't a luxury but a necessity: navigation, communicating with the hotel, keeping the children entertained on long journeys, and of course staying in touch with home. But how do you sort it out economically when 4–5 devices all need internet?
The one-eSIM + hotspot strategy
The most economical solution is simple:
- Install an eSIM on one phone for the destination (or region)
- Turn on the Wi-Fi hotspot on that phone
- The rest of the family connects to the hotspot — tablet, phone, laptop
This gets the whole family online from the price of a single eSIM data plan.
How big a data plan do you need?
| Use | Daily use (family of four) | For 7 days |
|---|---|---|
| Basic (maps, messages, occasional photo) | 0.5–1 GB | 3.5–7 GB |
| Medium (social media, photos, search) | 1–2 GB | 7–14 GB |
| Heavy (video, streaming, gaming) | 3–5 GB | 21–35 GB |
Our recommendation: For a one-week family holiday, a 10–15 GB plan is usually more than enough if you follow the data-saving tips.
Child-friendly settings
Turn off automatic downloads
- YouTube: Settings → Data saving → Wi-Fi only (this means hotel Wi-Fi, not the hotspot)
- App Store / Google Play: Disable automatic updates on mobile data
- Games: Download offline content in advance (Spotify music, Netflix episodes)
Prepare offline content
- Netflix/Disney+: Most streaming services allow offline downloads — do this over Wi-Fi at home
- Storybooks, games: Install apps that work offline
- Music: You can download favourite playlists on Spotify and YouTube Music too
Cost savings: eSIM vs. family roaming
| Solution | Family of four, 1 week, outside the EU |
|---|---|
| Roaming for everyone (4 × daily bundle) | Very expensive |
| 4 separate eSIMs | Moderate |
| 1 eSIM + hotspot | Cheapest |
The saving can be as much as 90% compared with roaming!
Practical tips
- Power bank: Running a hotspot drains the battery — bring a 10,000–20,000 mAh power bank
- Hotspot password: Set a strong password so strangers can't connect
- Backup: If one parent's phone runs out of battery, you can set up the other parent's phone with an eSIM too (as a backup)
- Hotel Wi-Fi: Use the hotel Wi-Fi in the room, and save the hotspot for excursions
Summary
On a family holiday, the best strategy is: one eSIM data plan + a Wi-Fi hotspot. Every family member can stay online while the eSIM provides internet at a fixed, prepaid price. The saving compared with roaming is significant, and setup takes just a few minutes.
