Here's the short version: for family and group travel, choose your connectivity around one question — "can everyone use it with confidence?" If everyone is comfortable with their phone and you stick together, sharing one plan via tethering can save money. But if you're traveling with kids, splitting up often, or have companions who feel unsure about settings, one eSIM per person is usually the easier path — it helps avoid the dreaded "I can't get online" and "we got separated and can't reach each other" moments. If you're torn, decide based on two things: "Will we always move together, or will we split up?" and "Does the person doing the tethering have a phone and battery to spare?" Below, we'll walk through how to think about data per person, what to watch for with tethering, and how to get everyone set up smoothly.
- One eSIM each suits splitting up; sharing suits saving money
- For anyone unsure about setup, or kids, one each is simpler in the end
- When sharing, allow extra data and mind the host phone's battery
- Rough guide: about 0.5–3GB per person per day — multiply by people × days
- No phone-number calls or SMS, but app-based calls work fine
Two things to decide first for family & group connectivity
Before you start preparing, settling these two points narrows your options fast. Leave them vague and you risk running short on the road — or buying far more than you'll ever use.
- Share or carry your own: split one plan via tethering, or give everyone their own eSIM.
- How much data you'll use: mostly maps, social media and quick searches, or plenty of video and video calls too?
The answers depend on who's traveling and how. For a short trip where the whole group stays together, sharing works well. But if you'll sightsee separately, meet up and part ways on the spot, or coordinate meeting points with kids or older family members, individual plans bring more peace of mind. The larger the group, the more one person's connection dropping can throw off everyone's plans — so confirm up front whether you'll be splitting up. If you'd like to scan prices and data guides by destination first, the eSIM comparison page lets you browse plans by destination, data and number of days, which makes it easier to picture.
"One eSIM each" vs. "sharing one": what each is good for
There's no single right answer — it comes down to your travel style. Start with the table below for the big picture.
| Factor | One eSIM each | Sharing one (tethering) |
|---|---|---|
| Splitting up | ◎ Everyone stays connected | △ No connection once away from the host phone |
| Cost | Adds up per person | Easier to keep down |
| Setup effort | Each person sets up their own | One host phone + connection settings |
| Battery | Spread across devices | Host phone drains faster |
| Data | Each person manages their own | Shared across the group |
One eSIM each suits you if: you'll split up, you want to stay in close contact, or you have family who feel unsure about settings and want everything to "just work on my own phone." Sharing suits you if: you'll always move together, you want to keep the budget down, or there's someone reliable to run the host phone. And it doesn't have to be all-or-nothing. If one family member isn't comfortable with phones, you might give just that person their own eSIM and share the rest, or give an independent teen who tends to wander off their own plan — these mix-and-match setups are practical and strike a good balance between cost and reassurance.
An honest look at tethering pitfalls
Tethering is handy, but a few things can trip you up if you're not expecting them. This isn't to alarm you — it's so you can stay relaxed on the day.
- Whether tethering is allowed depends on the plan and device. Even with unlimited-style plans, tethering (sharing) conditions can vary by plan, so check the latest details before you buy.
- Everyone shares the same data pool. One person streaming video can eat through the group's allowance fast. If you're sharing, it's wise to allow extra data.
- The host phone's battery drains quickly. The device doing the tethering takes a real hit, so a power bank is a good idea.
- Connected devices stop working once they're away from the host phone. If you plan to split up, sharing isn't a good fit.
It's tempting to assume "if it's unlimited, tethering covers everything," but even unlimited plans may come with a fair-use policy, speed management after a certain amount of use, or tethering conditions. Speeds also depend on the local network, area and congestion. If you're counting on heavy, long-running sharing, it's reassuring to confirm the conditions in advance.
For how to think about unlimited plans and when they fit, see the unlimited plan page as well.
How much data per person should you plan for?
Data use varies a lot, but a rough guide makes choosing easier. The figures below are an approximate per-person, per-day guide (a reference only — actual use varies with how you travel and the local network; as of June 2026).
| How you use it | Rough guide per person per day |
|---|---|
| Mostly maps, search and messaging | About 0.5–1GB |
| Plus posting to social media and photos | About 1–2GB |
| Plenty of video and video calls too | About 2–3GB or more |
If you're covering the whole group by sharing (tethering), roughly add up people × days × the per-day guide, then build in a little buffer. For example, a family of four using 1GB each per day over 5 days comes to 20GB as a floor — and more if you'll be watching video. Family use tends to spike unevenly — kids streaming video on the move, everyone piling onto a video call back at the hotel in the evening — so sizing up from the start lets you travel without watching the meter. If you're unsure whether your data will hold out, an unlimited-style plan is one option worth considering. To compare specifically by data, days and country, the comparison page is the clearest place to look, and for choosing among connectivity options overall, see comparing ways to stay connected abroad. If sharing is your plan and tethering conditions matter to you, things to know about tethering and unlimited eSIMs is also worth a read.
What to know about data-only plans, phone numbers and SMS
On family trips, people often ask "can I make a regular phone call there?" or worry "will my bank or booking site's SMS code come through?" Here's the honest answer.
Bloomy's eSIM is data-only by design. It doesn't replace calls or SMS tied to a regular phone number. The only things that won't work are phone-number calls (voice) and SMS — meanwhile, app-based calls and messages that run over data, like WhatsApp, Messenger and FaceTime, work as usual. For keeping in touch as a family and regrouping when you get separated, these app calls are more than enough — and even when sharing (tethering), as long as the connected device can use app calls, staying in touch is no problem. On the other hand, if anyone needs phone-number calls or SMS verification codes, it's worth lining up an alternative too (a local SIM or a plan that includes a number). Taking stock before you leave of who needs which kind of verification will save trouble on the trip.
Setting up as a family or group without the usual snags
The more people involved, the easier it is to stumble over "whose device is compatible?" and "when do we set this up?" Working through the steps below together before departure keeps things smooth.
- Check each device supports eSIM. Check everyone's phones before you leave — you can do so from checking eSIM-compatible devices. Older devices, or certain carrier states, may not be supported, so checking early is reassuring.
- Install before departure. For most plans, the safest flow is to add the eSIM at home and activate the line once you arrive (activation timing varies by plan, so follow the instructions).
- Help anyone unsure about settings ahead of time. Setting up together before you leave avoids a scramble on arrival. Having one family "setup person" makes the day go smoothly.
- Share the connection details with anyone who'll be sharing. Agreeing in advance on how to turn the host phone's tethering on and off, and the connection password, saves confusion abroad.
You can follow the specific steps in the setup guide. If you can't get online on arrival, check things in order — toggling airplane mode, activating the line, and the APN settings. Fixes are gathered in what to do when you can't connect, so it's worth a quick read before you leave, so that if anyone in the family runs into trouble you can calmly work through it.
