Andorra

The Blikst Andorra eSIM runs on Andorra Telecom, also known by its consumer brand Som. Andorra is a single-carrier market, so it is the only mobile operator in the country. The plan offers 2G and 3G speeds rather than LTE. In practice that comfortably handles WhatsApp, email, Google Maps navigation, ski-resort apps, mobile banking and light browsing. HD video streaming, big uploads and bandwidth-heavy remote work will be slow, so lean on lodge or cafe Wi-Fi for those.

Coverage follows the valleys, with consistent 3G across Andorra la Vella, Escaldes-Engordany, Encamp and Canillo, plus La Massana, Ordino and Pas de la Casa. The CG-2 over the Port d'Envalira and the CG-3 up to Ordino and Arcalis are covered along the valley floor. Honest weak spots exist: higher ridges and lift tops drop to 2G or nothing in places, and hiking passes above 2,500m like Estany de l'Illa and Coma Pedrosa have long offline stretches.

Right after purchase you get a confirmation email with your eSIM details, then you scan the QR code to install it. Do this over your home Wi-Fi before you travel. Activation is automatic: the plan switches on when you arrive in Andorra and the eSIM sees an Andorran tower. When you cross the border at La Farga de Moles on the Spanish side or Pas de la Casa on the French side, switch off airplane mode and the Andorra Telecom line registers itself.

Most modern smartphones work fully with Blikst eSIMs, though a few exceptions exist, so check our detailed compatibility list to confirm your device. Your phone also needs to be carrier-unlocked. To check eSIM support, on an iPhone look under Settings, General, About for an EID number, and on Android check the network or SIM settings. If you are unsure, that EID line is the quickest confirmation that your handset can hold a digital SIM.

It depends on your trip, and the 2G/3G ceiling keeps usage modest. A shopping-weekend day trip from Barcelona or Toulouse needs around 1 GB. A long ski weekend suits 1 to 3 GB. A week-long ski holiday in Soldeu or El Tarter with apartment Wi-Fi for streaming is usually fine on 3 GB. Two-week stays or summer hiking weeks are better on 5 GB, while extended property visits or seasonal workers rarely exceed 10 GB on this network tier.

Yes, tethering and hotspot use are supported, so you can share your connection with a laptop, tablet or a travelling companion's phone. Keep in mind the plan tops out at 2G/3G speeds, so a shared connection is best for messaging, maps, email and light browsing rather than HD streaming or large uploads. For data-heavy work or video, plan around lodge, apartment and cafe Wi-Fi instead, which is plenty for the ski apps and navigation most visitors actually rely on.

This is a data-only plan, so it does not include a local Andorran phone number for traditional calls or SMS. You can still call and message over the internet using apps like WhatsApp, FaceTime, Messenger or Telegram, which is exactly how ski instructors, cabin rentals and mountain guides in Andorra tend to communicate anyway. Because an eSIM is a separate digital line, you can leave your physical home SIM in the phone and keep your usual number for any essential texts or calls.

Almost certainly, because Andorra is the catch most visitors miss. It is neither in the EU nor the EEA, so roam-like-home does not apply and every traveller hits international rates at the border. Spanish and French domestic plans either block Andorra or charge premium roaming, and UK, US and Australian carriers do the same. Installing a Blikst eSIM before you cross means you land on local rates straight away and skip the sudden roaming-rate SMS shock.
