Network & Coverage

Stay connected across every corner of Sardinia

Your eSIM connects to TIM, Iliad and Wind — all three with 5G — across Sardinia and on through Italy. The phone takes whichever network is strongest where you stand.

TIM

5G coverage across Sardinia and on through Italy.

Iliad

5G coverage across Sardinia and on through Italy.

Wind

5G coverage across Sardinia and on through Italy.

Where you will use it

the Costa Smeralda in the northCagliari and the souththe west coast beachesthe mountainous interior

Sardinia has two airports nearly three hours apart and almost no rail worth using — everything depends on driving, and the interior is genuinely empty.

Does the Sardinia eSIM work outside the city?+

Yes — it is an Italy-wide plan. This page exists because people search for the city, not the country.

Can I share it as a hotspot in Sardinia?+

Yes. Tethering is allowed, which is what makes one unlimited line practical for a couple or a family moving around together.

How it works

Connected in
3 simple steps

Before you fly

Scan the QR code over Wi-Fi. About a minute.

On landing at CAG / OLB

Turn off flight mode — the line registers by itself.

Turn on data roaming

The step most travellers miss. It is not roaming in the billing sense; it is how the phone lets the eSIM use a foreign network.

✈️

Ready before you land

A rental car at Cagliari or Olbia, at opposite ends of a very large island — and your eSIM is already working when you get there.

Frequently asked questions

Everything you need to know about your Sardinia eSIM

Is the data truly unlimited?+

There is a fair use policy, as with every unlimited plan on the market. We publish the details on our fair use page rather than bury them, so you can check before you buy.

When does my Sardinia eSIM activate?+

On its first connection to a local network — in practice when you switch off flight mode at CAG / OLB. Not when you pay.

Can I buy it weeks before the trip?+

Yes. It stays dormant until it first connects, so buying it together with the flight is fine.

Should I buy a SIM card at the airport instead?+

You can, but it means queueing after a flight and paying whatever the counter asks. An eSIM bought beforehand is already working before you reach passport control.

Which devices are compatible?+

Any eSIM-capable handset — iPhone XS and newer, recent Samsung Galaxy, Pixel 3 and newer. Dial *#06# — if an EID number appears, you are good to go.

Can I extend it if I stay longer?+

We do not extend a plan that is already running. For more days, buy another eSIM for the same destination — it arrives by email and installs alongside the one you already have.

Only staying a few days?

A short trip is usually cheaper on a fixed data plan — same networks, one price for the trip.
