Traveling with a child who already has their own cell phone raises a very specific question: how to give them internet abroad without spending a fortune or signing contracts. An eSIM on the child's phone provides controlled data, allows you to locate them, and avoids roaming. Here's a practical guide designed for parents, not experts.
Can a minor use an eSIM?
Yes, without any technical or legal issue. An eSIM is just a data plan: it's not a line contract nor does it require the child to have one in their name. You buy and set it up yourself, as a mother or father, and install it on the minor's phone. They use it, you control it. It's the cleanest way to give them internet abroad.
The only requirement is that the child's phone is eSIM compatible, which is common in recent models. You can check in a minute with our list of eSIM compatible phones. If their phone is old and doesn't support it, you'll have to opt for a physical SIM.
Why an eSIM and not a local SIM or roaming
For a minor's phone, an eSIM wins for three clear reasons: you avoid roaming charges of €10-20/day that would inflate the bill, you don't have to give the child's passport at a foreign store to register a SIM, and you control spending because the plan has a fixed data limit. No surprise recharges.
In addition, you keep their Spanish line (if they have one) intact so they can continue to receive your calls. This is the same advantage of Dual SIM explained in how Dual SIM works. And compared to roaming, the price difference is clear in eSIM vs roaming.
| Option | Cost control | Registration with minor's details |
|---|---|---|
| Travel eSIM | High (fixed plan) | Not needed |
| Local foreign SIM | Medium | Usually requires ID |
| Operator roaming | Low (per day/MB) | No, but expensive |
How much data to give a child during the trip
Direct answer: for a minor on a family trip, 1 to 3 GB per week is usually enough, because families share hotel Wi-Fi a lot, and the child primarily uses their phone for messaging, music, and some games. If they watch a lot of videos on their phone, plan for more allowance.
As a guideline by age and usage:
- Basic use (messages, location, music): 1-2 GB per week.
- Medium use (social media, some videos): 3-5 GB per week.
- Intensive use (streaming, online games): better to get a larger plan or extend as needed.
Practical tip: give them a purposely adjusted plan. When the child sees that data is limited, they tend to use the accommodation's Wi-Fi more, and that way the phone doesn't become an unlimited screen during the holidays.

Parental control and data: how to combine them
The eSIM provides the connection, but you provide the control with the phone's own tools. On iPhone, you have Screen Time and Family Sharing; on Android, Family Link. With these, you limit apps, schedules, and purchases, and this configuration works the same with eSIM data as with Wi-Fi. The connection doesn't break your rules.
The ideal combination is simple: an eSIM with limited data so they don't browse endlessly, plus parental controls to decide which apps they can open and when. This gives them the autonomy to text you and use the map, but not an open bar for the internet. It's the balance most families seek when traveling.
Location and safety during the trip
For many parents, this is the number one reason. With active data on the child's phone, you can use real-time location (Find My on iPhone, Google Location) and know where they are in a theme park, on an excursion, or in a big city. Without data, this function becomes blind once they are out of Wi-Fi range.
It also allows them to message you instantly if they get separated from the group and use maps to return to the meeting point. It's the same peace of mind families seek in our guide to eSIM for family travel. Remember to teach them how to activate data and share their location before leaving.
How to prepare it yourself before leaving
It's best if you get everything ready from home, calmly, so the child only has to carry the phone. The process is the same as for any eSIM: you buy the plan, scan the QR code on their phone using your home Wi-Fi, and activate the data upon arrival at your destination. The full details are in how to install an eSIM.
- Check that their phone supports eSIM.
- Buy a suitable data plan for your travel destination.
- Scan the QR code on the minor's phone using home Wi-Fi.
- Set up parental controls and enable shared location.
- Upon arrival, activate the eSIM data and disable roaming.
Frequently asked questions
Is it legal to put an eSIM on my minor child's phone?
Yes. An eSIM is a prepaid data plan that you purchase and set up as an adult; it's not a line contract in the minor's name and does not require their documentation. You install it on their phone and control it from the purchase, just like you would pay for a top-up.
How many GB should I give a child for a week of travel?
For a minor on a family trip, 1 to 3 GB per week is usually enough, because they share the accommodation's Wi-Fi a lot and use their phone for messaging and music. If they watch a lot of videos, increase it to 5 GB. Giving them an adjusted plan also helps them not overuse the screen.
Can I control what they do online with the eSIM?
Yes. The eSIM only provides the connection; you enforce control with the phone's tools: Screen Time and Family Sharing on iPhone, or Family Link on Android. These limit apps, schedules, and purchases, and work the same with eSIM data as with Wi-Fi. Configure them before traveling.
Will I be able to locate my child if they have an eSIM?
Yes, and it's one of its great advantages. With active data, you can use real-time location (Find My on iPhone or Google's location) and know where they are on excursions or in large cities. Without data, this function stops updating once the child is out of Wi-Fi range.
Will they still receive my calls with the eSIM enabled?
Yes, if their phone keeps the Spanish SIM in Dual SIM mode. The eSIM provides data, and their usual number remains active for your calls and WhatsApp. To avoid roaming charges, only use the eSIM for data and the Spanish line solely for voice.
Conclusion
Giving your child's phone data abroad is easier, cheaper, and safer with an eSIM: you control it, avoid roaming, and can locate them. Combine it with the phone's parental controls, and you'll travel with greater peace of mind.
