How much mobile data does a family need on holiday: 2 adults and kids, worked out

Mykyta Dzhus · Updated 2026-11-13 · 18 min read · eSIM & mobile data

The hotel is booked, the tickets are bought and the kids' packing list is done. One question is usually left for the last evening: how much data to get for everyone. Your partner says the hotel Wi-Fi will do, the teenager wants unlimited, and the little one won't survive the transfer without cartoons. We worked out how many gigabytes a family with two adults and kids really uses, with four examples: Egypt with Wi-Fi in the room, Turkey with excursions, Thailand with a mum and a child, and a grandmother with her grandkids. The usage figures come from the official help pages of Netflix, Spotify, Apple and Google and from the norms of our «Family» calculator, where you can work out your own family in a minute.

In short

• Count per person, not «per family». Dad with messengers and maps uses 0.5 GB a day, mum with Instagram 1 GB, a child with cartoons 2 GB. That's a fourfold difference, so one figure for everyone is almost always wrong.
• A week for 2 adults and 2 kids: 7 GB for each adult, 14 GB for each child on YouTube, about 40 GB in all. If the room Wi-Fi is good and the kids watch cartoons on it in the evening, half of that will do.
• Video and video calls cost the most data. An hour of Netflix in standard quality is up to 0.7 GB, in HD up to 3 GB (Netflix's official help page). Messengers and maps cost almost nothing.
• Separate eSIMs or a hotspot? Adults with their own iPhones are better off with an eSIM each: you split up at the beach and on excursions. For little ones with a tablet, sharing from mum's phone is simpler.
• Work out your own family in our data calculator, «Family» mode: choose the country, the days and who's going, and it shows the GB per person, the plans and what's cheaper: an eSIM each or one shared.

How we worked it out

We didn't pull the numbers out of thin air. Data use has two parts.

Part one: how much each activity uses. Here we used official help pages wherever they exist. Netflix states how many gigabytes an hour each video quality takes. Spotify publishes the bitrate of each quality level, and we converted it to megabytes per hour. Apple explains what Low Data Mode turns off, and Google how offline maps work. YouTube, WhatsApp, Instagram and TikTok publish no usage figures, so for social media, video calls, messengers and maps we give our data calculator's averages and label them as such.

Part two: how people use their phone on holiday. Nobody counts minutes. So the «Family» mode puts people into four styles and gives each a daily norm. It's the same scale as in our roaming calculator and eSIM comparison, so the numbers match everywhere.

Why only 1 GB for games when kids play for hours? The online game itself sends little: tens of megabytes an hour. The data goes on updates, ads between rounds and other players' streams. Update the game at home over Wi-Fi and 1 GB a day is plenty.

We don't add a buffer on top: plans come in steps (5, 10, 20 GB), and you usually take a bigger one than the sum. We don't subtract hotel Wi-Fi in the main sum either, because there's none at the beach, in the transfer or on an excursion. But for each family below we show how much you can save if the room Wi-Fi works well.

How much data each activity uses

The table lists what people open most on holiday. Official figures are marked «official», our averages are marked as the calculator's estimate.

What's worth remembering. First, video costs tens of times more than anything else: an hour of cartoons in HD can cost as much as a week of messengers. Second, quality decides everything. According to Netflix, in the phone app on «Automatic» 1 GB lasts about 4 hours, and on «Maximum Data» only 20 minutes. That's a twelvefold difference, and on a small phone screen you hardly see it. Third, music and maps are almost free: even at Spotify's highest quality an hour of music is about 144 MB.

Netflix gives its figures as «up to», so they're the upper limit. YouTube and social apps work in a similar way: quality adapts to speed, and on good 4G or 5G the phone switches to higher quality by itself, which means more data. That's why the first tip in «How to save data» is to fix the video quality.

Family 1: mum, dad and two kids, a week in Egypt with Wi-Fi in the room

Who's going: mum with an iPhone (Instagram, photos, Viber with granny), dad (news, messengers, maps), a 12-year-old son with his own phone (YouTube, Brawl Stars) and a 6-year-old daughter without a phone who watches cartoons on mum's. An all-inclusive hotel in Hurghada with Wi-Fi in the room.

The norms for 7 days:

• mum, «Social media»: 1 GB × 7 = 7 GB;
• dad, «Messengers»: 0.5 GB × 7 = 3.5 GB;
• son, «Video»: 2 GB × 7 = 14 GB;
• daughter, «Video» on mum's hotspot: 2 GB × 7 = 14 GB.

That's 38.5 GB in all, 21 GB of it through mum's phone. This is without Wi-Fi.

Now, honestly, about the room Wi-Fi. In many hotels Wi-Fi works well in the room and the lobby and gets weaker at the pool and on the beach. If cartoons and games in the evening go over the room Wi-Fi, daytime video at the beach is about an hour a day for the kids. Then the daughter really uses about 1 GB a day, the son about 1 GB too, and mum and dad stay at their norms.

What to get:

• Mum (her own + the daughter's hotspot, 7 + 7 = 14 GB): 20 GB for 30 days, $25.99.
• Son (with room Wi-Fi about 7–10 GB): 10 GB, $16.49. If he watches YouTube all day at the beach too, take 20 GB as well.
• Dad (3.5 GB): 5 GB, $10.49. If he likes video too, 10 GB.

One more way to save: the 10% discount applies to identical eSIMs in one order. So if mum and the son both need 20 GB, buy two identical 20 GB eSIMs in one order and the second is 10% cheaper. Another option if you'd rather not count: a week of unlimited, $23.49. It gives 2 GB a day at full speed, then the speed drops. For mum, who also shares with her daughter, 2 GB a day may not be enough, but for the teenage son it's exactly his norm.

Check your exact mix in the «Family» calculator for Egypt: it works out all three options and shows the cheapest.

Family 2: a couple and a teenager, 2 weeks in Turkey with excursions

Who's going: mum and dad with their own iPhones and a 15-year-old daughter. The first week at a hotel in Kemer, the second on the move: Cappadocia, Pamukkale, a day in Istanbul. Hotel Wi-Fi doesn't help much here: half the time you're on a bus, on an excursion or looking for a restaurant in a new town.

The norms for 14 days:

• mum, «Social media» (photos, stories, Viber with family): 1 GB × 14 = 14 GB;
• dad, «Social media» (maps, taxis, bookings, news): 1 GB × 14 = 14 GB;
• daughter, «Video» (TikTok, YouTube, series on the bus): 2 GB × 14 = 28 GB.

56 GB in all. We put the parents on «Social media», not «Messengers», because on a trip with excursions you open maps, the translator and the camera far more often than on a beach holiday.

What to get:

• Mum and dad: 20 GB for 30 days each, $15.49 each, in one purchase with quantity 2: the second eSIM is 10% cheaper. 14 GB of norm plus room for photos and video calls.
• Daughter: 15 days of unlimited, $27.99. It gives 2 GB a day at full speed, exactly her norm, and she doesn't have to count gigabytes. For someone who watches even more: the big 50 GB plan for 180 days, $28.99, which will also last for the next trip.

Why not share from mum's phone? Because a teenager on an excursion doesn't stand next to mum, and a hotspot reaches only a few metres. An eSIM of her own also means peace of mind for the parents: she's always reachable, even if she gets lost in the Grand Bazaar.

Would it be cheaper to stay on roaming? Compare in the roaming cost calculator: choose Turkey, 14 days and 3 phones, and it shows your operator's price next to the eSIM. More on operator prices: “How much a week of roaming costs with Kyivstar, Vodafone and lifecell: 25 countries (2026)”.

Family 3: a mum and her child, 10 days in Thailand

Who's going: mum with an iPhone and a 7-year-old son with a tablet without a SIM. Phuket, then a few days on an island. A long flight with a connection, a transfer, ferries, Grab instead of taxis. Mum is on her own, so data isn't entertainment here, it's safety: maps, keeping in touch with the hotel, translation, payments.

The norms for 10 days:

• mum, «Social media»: 1 GB × 10 = 10 GB;
• son on the tablet via mum's hotspot, «Video»: 2 GB × 10 = 20 GB.

30 GB in all, and all of it on mum's phone, because the tablet has neither a SIM nor an eSIM.

What to get: one big plan. Thailand has 50 GB for exactly 10 days, $14.99: with room for flights and rainy days when the cartoons run longer. If the hotel Wi-Fi is good and the son watches mostly in the evening in the room, 20 GB for 30 days will do, $17.99.

15 days of unlimited ($33.49) is a worse choice here than it looks. It gives 2 GB a day at full speed, and mum with a hotspot needs about 3 GB. After the allowance the speed drops, and cartoons on the tablet start to freeze at the worst moment, in the ferry queue.

Important for a mum travelling alone: download offline maps of Phuket and the island at home (“How to download Google Maps offline (plus Maps.me and Organic Maps): step by step on iPhone and Android, 2026”), and download cartoons to the tablet over home Wi-Fi in apps that allow it. Then everything works even with no signal on the road. Take a power bank: a phone that shares its connection drains much faster.

Family 4: a grandmother with her grandkids

Who's going: a 64-year-old grandmother with an Android phone and two grandkids, 8 and 10, with a tablet. Sharm El Sheikh, 10 days. The parents stay at home and want to see the kids on a video call every evening.

The sum for 10 days:

• grandmother, «Messengers»: 0.5 GB × 10 = 5 GB;
• a daily half-hour video call to the parents: by our calculator's estimate 0.3–0.8 GB an hour, so up to 0.4 GB a day, up to 4 GB in 10 days;
• the grandkids on the tablet via granny's hotspot: if cartoons are mostly in the evening on hotel Wi-Fi and an hour at the beach in the daytime, about 1 GB a day, 10 GB in 10 days.

About 19 GB in all, all through granny's phone.

What to get: one 20 GB eSIM for 30 days for the grandmother, $25.99. If the kids watch little or the hotel Wi-Fi is good, 10 GB will do, $16.49. If it runs out, she can top up with another plan in a minute.

The main thing here isn't gigabytes, it's the set-up. It will be hard for granny to find the eSIM and hotspot settings on the phone. So:

• check at home that her phone supports eSIM (“Compatible devices”); older and budget Android phones often don't;
• install the eSIM yourself, at home over Wi-Fi, with the installation guide;
• turn on the hotspot on her phone in advance, set a simple password and connect the tablet to it: after that the tablet will connect by itself;
• turn off data roaming on her main SIM so no bill arrives, and keep calls and texts on.

If granny's phone doesn't support eSIM, the easiest fix is to give her an old iPhone with an eSIM, or put the eSIM on the older grandchild's phone if it's a modern one.

One eSIM for everyone or one each

Let's start with something people often mix up: one eSIM works in one phone only. You can't buy one eSIM and install it on three iPhones. That's why checkout on our site has a «How many eSIMs?» line with the hint «One per phone». The only way to share data with others is a hotspot (on iPhone, «Personal Hotspot»).

Option 1. An eSIM each.

• Pros: everyone is independent. Dad has gone fishing, the teenager is at the other end of the beach, you're at the spa, and everyone has data. Each person sees their own balance and doesn't eat someone else's.
• Pros: phones don't drain from sharing.
• Cons: more expensive than one big eSIM. But the 2nd and later identical eSIMs in one order are 10% cheaper: at checkout you'll see a «2nd and later −10%» line and the total for the whole family.

Option 2. One big eSIM and a hotspot from one phone.

• Pros: the cheapest. One big plan costs less than several small ones.
• Cons: the sharing phone drains much faster, so you need a power bank.
• Cons: everyone has to stay close. A hotspot reaches a few metres, up to 10 metres from the phone.
• Cons: the speed is shared. Two videos in normal quality at once are usually fine, HD may stutter.
• Cons: how many devices can join, Apple says, depends on the iPhone model and the network. And some plans may limit sharing, so before buying a big plan for a hotspot, check with our support.

Option 3, often the best: mixed. Adults on their own eSIMs, little ones without phones on mum's hotspot. You don't pay for an eSIM for the tablet, and dad doesn't depend on mum's phone.

Our advice: adults and teenagers with their own phones get an eSIM each. Kids under 12 with a tablet or an old phone without eSIM use a parent's hotspot. That's honest, and simpler than buying a child a new phone for the trip. On iPhone the hotspot is in Settings → Personal Hotspot → Allow Others to Join. If the tablet is on the same Apple Account or in Family Sharing, Apple lets it connect even faster via Instant Hotspot.

Work out all three options for your family in the «Family» mode: it shows the price of each and marks the cheapest.

How to save data

Five settings that take 10 minutes at home and save half a plan.

1. Offline maps. In Google Maps on iPhone, search for the town, tap its name, then More → Download offline map. Driving navigation works offline if the whole route is inside the downloaded map; walking and transit directions don't work offline. Maps expire, and Google updates them by itself when you're on Wi-Fi. Step by step: “How to download Google Maps offline (plus Maps.me and Organic Maps): step by step on iPhone and Android, 2026”.

2. Video quality. In YouTube: profile picture → Settings → Video quality preferences, and choose Data saver for mobile networks. In the Netflix app choose Save Data for mobile data: according to Netflix, that's about 6 hours of viewing per GB. For a child watching cartoons on a phone, you hardly see the difference.

3. Auto-download in messengers. Family chats on holiday mean hundreds of photos and videos a day. In Telegram, Viber and WhatsApp, in the data and storage settings, turn off auto-download of videos over mobile data; photos can stay on. Open what you need by hand.

4. Updates and cloud photos. On iPhone, turn on Low Data Mode for the eSIM: Settings → Cellular → your eSIM → Data Mode. According to Apple, it turns off Background App Refresh, automatic downloads and backups, pauses iCloud Photos and lowers streaming quality. Photos will sync in the evening over Wi-Fi.

5. Block the greedy apps. At the bottom of Settings → Cellular there's a list of apps and how much each has used. Turn off mobile data for what you don't need on holiday: games with big updates, cloud drives, streaming apps you don't use. According to Apple, those apps then work over Wi-Fi only.

A bonus for kids: download cartoons to the tablet at home in apps that allow offline viewing. On the plane and in the transfer it saves both nerves and data.

Traps that empty a plan in one evening

We see these three most often when a customer writes to support saying «my plan vanished in a day».

Background updates. After landing, the iPhone is glad to have data and starts updating everything: apps, podcasts, sometimes iOS itself if downloads over cellular are allowed in settings. The fix: Low Data Mode on the eSIM and automatic App Store updates over cellular turned off.

iCloud and cloud photos. The first day at the sea means hundreds of photos and a few 4K videos. If iCloud Photos or Google Photos upload them over mobile data, several gigabytes disappear unnoticed. The same goes for WhatsApp and Viber backups. The fix: allow syncing over Wi-Fi only.

Video autoplay. Instagram, TikTok, Facebook and YouTube start videos as soon as you scroll, at the highest quality the network allows. 20 minutes of Reels before bed can easily equal a day's norm. The fix: turn on the data saver in Instagram's and TikTok's settings, and Data saver in YouTube.

And one quieter trap. The Apple feature that props up weak Wi-Fi with mobile data (called Connectivity Assist in recent iOS) may, according to Apple, use extra mobile data. On weak hotel Wi-Fi the phone quietly pulls data from the eSIM. If your plan is small, turn it off in Settings → Cellular.

And don't forget to turn off data roaming on your main SIM: otherwise the phone may use it for data and your operator will send a bill. The roaming cost calculator shows how much that costs. If the eSIM has no data after landing: “Mobile Data Not Working Abroad? Roaming Limits + 12 Fixes (2026)”.
