Travel Data Explained (2026): Roaming vs Local SIM vs eSIM

Written by WayStaq Team · 7 min read

If you get travel data wrong, everything becomes harder. Maps lag, bookings fail, taxis don’t arrive, and suddenly you’re relying on patchy WiFi and guesswork.

Most people don’t plan this part. They land, turn data on, and deal with whatever happens.

That’s how you end up overpaying or under-connected.

Here’s what actually works in 2026 — with real trade-offs, not theory.

Option 1: Roaming (using your UK SIM abroad)

This is the easiest option. You land, your phone connects, and everything just works.

Typical cost: £5–£15 per day outside Europe

But the cost adds up fast — especially for families.

Four people roaming at £10/day = £40/day. Over two weeks, that’s £560 just for data.

💡 Roaming is convenient — but it’s rarely good value outside short trips.

Option 2: Local SIM cards (buying in-country)

This is still the cheapest option in most places.

Typical cost: £5–£15 for 10–30GB in countries like Thailand or Malaysia

Popular providers include:

But there’s friction:

After a long flight with kids, that friction matters more than you think.

💡 Best for: longer stays in one country where saving money matters.

Option 3: eSIMs (digital data plans)

eSIMs sit in the middle — more expensive than local SIMs, but far easier.

Typical cost: £15–£30 for 5–20GB

Popular providers:

The downside is price and choice overload — there are dozens of plans, and not all are good.

You also need a compatible phone (most modern iPhones and many Androids support eSIM).

💡 Best for: multi-country trips or travellers who want simplicity without roaming prices.

What we actually use as a travelling family

Here’s the honest answer — we don’t use one option. We combine them.
