Roaming Charges in Andorra: Avoid an Unexpected Bill

NoveSIM | Last updated on: September 23, 2026 | 5 minute read

Roaming charges in Andorra can surprise travellers arriving from Spain or France. The principality is not automatically covered by the EU’s roam-like-at-home rules, and each mobile operator decides whether Andorra is included in a plan, pass or separate charging zone.

The safest approach is to check the carrier’s current Andorra entry before departure. Do not treat Schengen membership, the euro currency or the country’s position between EU states as evidence of included mobile roaming.

NoveSIM travel eSIMs are data-only and do not provide ordinary calls or SMS. They can keep apps online while the home SIM remains available for a normal number, provided its own roaming settings are controlled.

Quick answer: Check whether your exact home plan names Andorra. If it does not, disable Data Roaming and automatic data switching on the home SIM before the border. Use a plan that explicitly covers Andorra and select that line for Mobile Data.

Why Can Roaming Charges in Andorra Be Different?

EU roaming protections apply within their defined regulatory area; Andorra has historically sat outside the automatic coverage travellers expect in neighbouring countries. Some carriers voluntarily include it, while others sell a daily pass or apply a separate rate.

Only the home carrier can confirm the charge for your subscription. Check data, outgoing calls, incoming calls, voicemail and SMS separately, because one included service does not prove that all services are included.

What Can Trigger Roaming Charges?

  • Background app updates or cloud photo uploads.
  • Automatic switching from a travel eSIM to the home SIM.
  • Answering or making conventional calls through the home carrier.
  • Voicemail forwarding or retrieval under the carrier’s roaming rules.
  • A weak Spanish or French signal giving way to an Andorran network near the border.

A few seconds of background data can be enough to create a daily-pass charge on some plans. Current prices are carrier-specific and should be verified directly rather than copied from an older travel article.

How to Prevent Accidental Home-SIM Data Use

  1. Open the phone’s Cellular, Mobile Network or SIM Manager settings.
  2. Switch off Data Roaming for the home SIM.
  3. Choose the Andorra travel eSIM as the Mobile Data line.
  4. Disable automatic or cellular data switching.
  5. Confirm that personal hotspot and cloud backup are not using the wrong line.
  6. Check the displayed SIM label after crossing the border.

The detailed guide to checking which SIM handles mobile data helps prevent the home line from taking over silently.

Should Data Roaming Be On for a Travel eSIM?

Often yes. A travel eSIM may connect through a roaming partnership and therefore require Data Roaming on its own line. That is separate from the home SIM’s roaming switch.

Follow the plan instructions and use the travel eSIM roaming guide. Enable the setting only on the intended data line and keep the home line excluded from Mobile Data.

Are Calls and SMS Covered by a Travel eSIM?

NoveSIM plans supply mobile data, not a local Andorran number or conventional voice and SMS. WhatsApp, FaceTime, Signal and other internet services work when data is active. Calls and texts through the home SIM remain subject to the home carrier’s terms.

If you keep the primary number active for incoming messages, confirm whether receiving a call, accessing voicemail or sending an SMS creates a charge. The guide to keeping a number while using an eSIM for data explains the dual-SIM arrangement.

What to Do at the Border

Download maps and essential details while still connected in Spain or France. Shortly before crossing, verify the selected data line and take a screenshot of the settings. After the phone registers in Andorra, test a simple website with Wi-Fi switched off.

If data fails, use Airplane Mode briefly and leave network selection on Automatic for the first attempt. Do not delete the eSIM. Preserve it and confirm plan coverage, line selection, roaming and APN before contacting support.

FAQ

Is Andorra included in free EU roaming?

Not automatically. Some carriers include it voluntarily, but others charge separately. Check the country list for your exact plan.

Can my phone connect to Andorra Telecom automatically?

Yes, it may switch networks near the border. The charge depends on the SIM used for data and that provider’s roaming agreement.

Will turning off Data Roaming stop calls?

It stops roaming data on that line, not necessarily conventional calls or SMS. Control voice and messaging use separately according to the carrier’s terms.

Can I keep my home SIM switched on?

Yes, but keep it excluded from Mobile Data, disable its Data Roaming and understand any charges for calls, SMS and voicemail.

Final Recommendation

To avoid unexpected roaming charges in Andorra, do not cross the border with an unchecked EU roaming assumption. Verify the carrier’s Andorra policy and save the relevant terms before travelling.

Select a plan that explicitly covers Andorra, disable automatic data switching and keep roaming off on the home SIM. Enable it on the travel eSIM only when required.

These controls protect against background data and network changes at the border while keeping maps and messaging available.
