Best eSIM for Andorra

Andorra catches people out for one specific reason: it is not in the European Union, so EU roaming rules do not apply there. Travellers who drive up from Barcelona or Toulouse and expect their phone to keep behaving as it did in Spain or France can find themselves outside their allowance the moment they cross into the valleys. There is no airport — you arrive by road, through the border post, usually heading for Andorra la Vella for shopping or up to Grandvalira and Vallnord for skiing. A data plan that explicitly covers Andorra removes the surprise. It also keeps you online for lift status, mountain weather and the winding descent back down the N-145 or N-20.

Andorra has a single operator, the state-owned Andorra Telecom, which is why coverage here is a matter of terrain rather than competition. It is dense where the country is: Andorra la Vella, Escaldes-Engordany, Encamp, La Massana, Ordino and Pas de la Casa all have strong service, and the ski areas are well covered around lifts and pistes because the network was built for them. Deep in the side valleys, on hiking routes above the tree line and in road tunnels, signal drops out as you would expect in the Pyrenees.

Because EU roaming does not extend to Andorra, a European roaming allowance you already have almost certainly stops at the border, and out-of-bundle charges apply instead. Buying a local Andorra Telecom prepaid SIM works but is a shop errand for what is often a two- or three-day visit. A plan bought in advance that covers Andorra is the cleanest answer for skiers and weekend shoppers alike.
