Traveller's guide

Staying connected in Sardinia

A weak connection does not just feel slow — it wastes your plan. Pages half-load and reload, uploads restart, apps retry in the background. Sitting on a solid network is part of what makes a fixed plan last the whole trip.

In Sardinia the biggest single draw is navigation on the interior and coastal roads, where villages are far apart. Download the offline map before you fly and let the eSIM handle live traffic only.

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

How it works

Connected in 3 simple steps

Whenever you like

On landing at CAG / OLB

Turn off flight mode.

Turn on data roaming

The step most people forget. Your home SIM stays in the phone for bank codes, with its data switched off.

FAQ

Questions, answered

Will the Sardinia eSIM work on my phone?

Any eSIM-capable, carrier-unlocked handset — iPhone XS and newer, Samsung Galaxy S20 and newer, Pixel 3 and newer. Dial *#06#; an EID number means yes.

How fast is the data in Sardinia?

4G and 5G where the local network provides it. Speed varies by area and time of day, as it does for everyone on the same network.

Do I need a passport or registration?

No. That requirement applies to physical SIM cards bought locally, not to this eSIM.

When does my plan start?

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

What happens when my data runs out?

Your connection simply pauses — no surprise bills, ever. To keep going, buy another package for the same destination. If that happens often, the unlimited plan is the cheaper answer.

Can I add data to an eSIM I already have?

No — we don't offer top-ups. If you need more data, buy another package for the same destination. It arrives by email and installs alongside the eSIM you already have.

Can I keep my normal number for calls and texts?

Yes. Keep the home line active for SMS codes with its data off, and let the eSIM carry the data.

Can I use it as a mobile hotspot in Sardinia?

Yes. Bear in mind a second device draws from the same plan.

Does it work outside Sardinia?

Yes — it is an Italy-wide plan.

Staying longer than a week?

Unlimited is billed per day and the daily rate falls the longer you stay — same networks, no counting.
