Your eSIM automatically connects to the best available network — no manual switching.
Andorra has a single carrier: Andorra Telecom (STA service, historic state monopoly). 4G covers the entire principality (468 km²) including Andorra la Vella, Encamp, La Massana, and all ski resorts (Grandvalira, Vallnord). 5G in urban areas and main pistes. The eSIM Ahora connects via roaming with Andorra Telecom. Plugs are Type C and F (standard European, same as Spain and France), 230V — no adapter needed from the EU.
Andorra has no commercial airport — you arrive by car from Barcelona/Toulouse or direct bus from Madrid. The currency is the euro (Andorra isn't EU but uses the euro). Crèdit Andorrà, MoraBanc, and Andbank ATMs accept foreign cards. Tips are 10%. Andorra is a VAT-free tax haven — alcohol, perfumes, electronics are 20-30% cheaper than in Spain/France (customs limits when crossing). Catalan is official but Spanish works fine. Most tourism is skiing (December-April).
