Quick answer
For a family holiday, individual travel eSIMs work best when every person carries a modern, eSIM-compatible phone and wants their own connection. Portable WiFi works best for connecting several devices at once, including children’s tablets and older phones that cannot take an eSIM, all from one shared data allowance. Many families use both: eSIMs on the adults’ phones and a portable WiFi router for the kids and shared devices.
Keeping a whole family connected abroad is a different problem from keeping one phone online. You are juggling several devices, mixed ages, kids’ tablets, varying phone models, and a single holiday budget. The right answer depends on how many devices you need online and whether everyone’s phone even supports an eSIM. This guide compares the two options clearly, then shows the hybrid setup most families settle on.
eSIM vs. portable WiFi for families: Which is better?
Neither wins outright; they solve different problems. An eSIM gives each phone its own independent, always-on connection with no extra device to carry or charge. Portable WiFi creates one shared network that any device can join, which is ideal when several of those devices cannot take an eSIM. The table below shows where each pulls ahead.
| Factor | Travel eSIM (per phone) | Portable WiFi router |
| Devices covered | One phone per eSIM | 8–16 devices on one connection |
| Works with kids’ Wi-Fi-only tablets | No | Yes |
| Works with older / non-eSIM phones | No | Yes |
| An extra device to carry and charge | No | Yes (router + battery) |
| Everyone stays online if they split up | Yes, each phone is independent | No, must stay near the router |
| Cost for a large group | Adds up (one plan per phone) | One shared plan, cheaper per device |
| Price vs. a bare router from a retailer like Amazon.co.uk | N/A – no physical device to compare | Device prices are similar, but every WorldSIM MiFi & Wi-Fi is network unlocked and ships with a free international data SIM valid in 188 countries, so the all-in cost is often lower than buying a router on Amazon.co.uk and sourcing international data separately |
| Calls and SMS on a real number | Available on eSIM Pro plans | Data only |
When does a family eSIM setup make sense?
Choose individual eSIMs when every family member carries a modern, unlocked, eSIM-compatible phone and at least the adults want to stay reachable even when the group splits up, for example, one parent at the beach and another at the shops. Each phone keeps its own data and number, so no one loses connection by wandering off. It is the tidiest option for couples and families with teenagers.
Because most travel eSIMs are data-only, families who also want to make and receive calls should look at a plan that includes voice. A WorldSIM eSIM Pro includes call minutes, SMS, and a UK and USA number, which is useful when a parent needs to phone a restaurant, an excursion desk, or a teenager who has wandered off in a theme park.
When is portable WiFi the better choice for families?
Portable WiFi wins when you have several devices to connect, and some of them cannot take an eSIM. A typical family carries phones, two or three tablets, maybe a laptop, and an e-reader, and many of those tablets are Wi-Fi-only. One portable WiFi router connects them all to a single data plan, so you are not buying a connectivity device by device.
It is also the simpler mental model for younger children: there is one “holiday Wi-Fi” everyone joins, exactly like at home. The trade-offs are an extra gadget to charge and the need to stay roughly within range of whoever is carrying it.
On price, a WorldSIM router holds up well against buying a bare device from a general retailer like Amazon.co.uk. Device costs are similar, but every WorldSIM router comes with a free international data SIM valid in 188 countries, included in the price, so families are not paying again for global data once the router arrives. Bare routers bought elsewhere often need an international SIM sourced separately, which usually closes the gap or tips the total cost in WorldSIM’s favor.
How many devices can a portable WiFi router handle?
Most travel routers connect between 8 and 32 devices at once, which covers a large family with room to spare. They all share one data allowance, so performance is smoothest when not everyone streams high-definition video simultaneously. For a family of four to six, a single router is almost always enough. WorldSIM stocks routers from Huawei and ZTE with 4G and 5G options.
How much data does a family use on holiday?
Families use far more data than solo travellers, mainly because children stream video on tablets. Plan generously to avoid running out mid-trip. As a rough guide, allow 1 to 2GB per person per day when there is regular streaming.
| Family Scenario | Usage Pattern | Suggested Data for 1 Week |
| Family of 4, light | Maps, messaging, and hotel Wi-Fi most evenings | 15–20 GB |
| Family of 4, typical | Daily tablet streaming, social media, and photos | 30–50 GB |
| Family of 5–6, heavy | Multiple devices streaming, video calls at home | 60 GB+ or unlimited-style plan |
Streaming is the dominant cost: HD video can use over 1 GB per hour per device, while maps and messaging use only a few MB. A single child watching cartoons for two hours a day can account for most of a family’s usage.
The hybrid setup most families land on
In practice, many families combine both. The adults run eSIMs on their phones so they stay independently reachable, while a portable WiFi router covers the children’s tablets and any shared or older devices. This keeps parents contactable when the group splits, gives the kids a familiar single network, and spreads the children’s heavy streaming across one cost-effective shared plan rather than several individual ones.
Country-Specific Price Comparison: WorldSIM eSIM Pro vs. Vodafone, EE, Lyca and Lebara
Travellers heading abroad this summer are most likely to start with what they already know: their existing network or a familiar high-street name. Vodafone and EE are the default roaming options for millions of UK subscribers, while Lyca and Lebara are popular prepaid MVNOs with a strong UK base. But familiarity is not the same as value, and for a digital nomad who needs more than data, these providers fall short in one critical area.
None of them includes voice calls or SMS as standard on their international travel plans. That means no client calls, no OTP codes, and no local contact number, all handled over data or not at all. WorldSIM eSIM Pro is the only plan in this comparison that bundles calls, SMS, and data into a single line at a price that still undercuts the competition on comparable data allowances.
The table below compares WorldSIM eSIM Pro against these four UK providers on the features that matter most for working abroad.
| Provider | Starting Price | PAYG / Prepaid | Voice Calls / per min | SMS | OTP Supported | Data / per mb | Data Bundles | Validity | Network Supported | Activation |
| WorldSIM | £25.00 | Yes | Incoming

Frequently asked questions
Is an eSIM or portable WiFi better for a family holiday?
It depends on your devices. Individual eSIMs are best when each person has an eSIM-compatible phone and wants their own connection. Portable WiFi is best for connecting many devices at once, including kids’ tablets and older phones, from one shared allowance. Many families use both: eSIMs on the adults’ phones and a router for everyone else.
How many devices can a portable WiFi router connect at once?
Most travel routers connect 8 to 32 devices simultaneously, enough for a family of four to six with phones, tablets and a laptop. They share one allowance, so performance is best when not everyone streams heavy video at the same time.
How much mobile data does a family use on holiday?
Plan around 1 to 2 GB per person per day with regular streaming, so a family of four on a one-week trip might use 30 to 50 GB. Families relying mainly on hotel Wi-Fi in the evenings will use considerably less.
Do kids’ tablets work with a travel eSIM?
Only if the tablet has cellular support and is eSIM-compatible, which many Wi-Fi-only tablets are not. This is the main reason families choose portable WiFi: one router connects Wi-Fi-only tablets, e-readers and older phones without a separate plan for each.
What is the cheapest way to keep a whole family online abroad?
For larger families with several devices, a portable WiFi router sharing one allowance is usually cheaper per device than an eSIM for everyone. For a couple or small family where all have modern phones, individual eSIMs can be more cost-effective. Compare one shared plan against several individual plans for your exact group size.
Can a WorldSIM eSIM Pro receive OTPs from banks and government sites?
Yes. WorldSIM’s eSIM Pro is SMS-enabled and receives one-time passwords from UK banks (Barclays, Monzo, HSBC), HMRC, PayPal, Apple, and Google in 195+ countries, just like a physical SIM.
