Paris: the visa file, the EU data plan, and the tickets that are gone by March.

France has four main operators — Orange, SFR, Bouygues Telecom and Free Mobile — and a competitive prepaid market. But the reason connectivity works differently here has nothing to do with which one you pick. Under the European Union's roaming framework, a plan from an EU operator is usable across EU member states on broadly the same terms as at home. For an Indian traveller doing Paris plus Amsterdam plus Rome, that means one plan rather than a SIM in every country.

That makes an EU-wide eSIM the natural purchase for a European trip. Buy it in India, activate before boarding, and you land at Charles de Gaulle with data live — which matters because everything you need in the first hour is app-based. The rail app, the transport app, the ride-hailing app and the museum tickets you already booked all assume you are online, and the free airport wifi is functional rather than pleasant.

The alternative is a French prepaid SIM, which is straightforward to buy in the city but less convenient at the airport, where retail hours and queues do not always align with an early-morning arrival. Roaming on an Indian carrier is the third option and typically the most expensive per day in Europe of anywhere on this list, so check the pack rate carefully before defaulting to it.

Two practical notes. Coverage in Paris and along the TGV corridors is excellent, but signal drops on long tunnel sections and in parts of the Metro. And if your itinerary includes Switzerland or the United Kingdom, check them explicitly — neither is inside the EU roaming framework, and plans that say 'Europe' do not always include them.

This is the section that separates France from every other destination on this list. Applicants for a Schengen short-stay visa are required to provide travel medical insurance as part of the application. The criteria are defined at Schengen level rather than by an individual insurer: the cover must be valid throughout the Schengen area, it must cover the entire period of the intended stay, and it must cover emergency medical treatment, urgent hospitalisation and repatriation — including repatriation for medical reasons and repatriation of remains — to at least the minimum level the rules specify.

Two cautions matter more than the requirement itself. First, insurers market 'Schengen-compliant' policies, and a policy meeting the published criteria is still assessed by the consulate along with the rest of your file. Buying one does not mean the consulate will accept it, and it certainly does not mean the visa will be granted. Second, the required minimum cover level, the accepted documentation format and the list of insurers recognised by a given consulate are all set by the authorities and change. Confirm the current requirement on France-Visas and with the visa application centre handling your file, before you pay for a policy.

Separately from the paperwork, the cover is genuinely useful. Healthcare in France is excellent and, for a visitor, billed. Winter sports in the Alps sit outside standard cover unless you add them. Rail strikes and weather disruption are ordinary features of European travel and are exactly what curtailment and delay cover is for. And because Schengen trips are usually multi-country, a policy that names the whole area rather than one country is the correct shape anyway.

One more thing to know about the wider process: the European Union is phasing in new entry-exit and travel authorisation systems, which affect procedures at the border and for some travellers' pre-travel formalities. What applies to an Indian passport holder with a Schengen visa is a question for the official source, not an article.

From Charles de Gaulle, the RER B suburban train runs directly to Gare du Nord, Châtelet–Les Halles and on through the centre. It is usually the quickest way in and the least expensive of the three, and it is also the one most likely to involve stairs, crowding and opportunistic pickpocketing — travelling with large cases at rush hour is genuinely unpleasant on it. The Roissybus coach to Opéra is slower but simpler with luggage. Taxis from Paris airports operate on regulated flat fares to defined halves of the city, which removes the meter argument entirely; take them from the official rank rather than from anyone approaching you inside the terminal.

Orly is closer to the centre and now connected by an extension of Métro Line 14, which changed the calculus for travellers arriving there — a direct Métro into the middle of Paris is considerably easier than the older combination of shuttle and suburban rail.

Beauvais is the one to be careful with. It is a long way from Paris and the only sensible connection is the dedicated coach, which is timed to flights and takes a substantial part of an evening. If a low fare lands you there, price the coach and the time into the decision.

In the city, buy a travel pass or a rechargeable card rather than paper singles, and check which zones you need — the airports and Versailles sit outside the central zones that most day passes cover.

Paris moved to timed entry across its major institutions and never moved back. That changes the planning order for an Indian traveller: you book the museums when you book the flights, not when you land. The Eiffel Tower summit and the Catacombs in particular are gone months ahead in the high season.

The museum pass is still worth evaluating, but understand what it does. It covers admission at many sites and can skip a ticket queue, but at the busiest institutions it does not replace a timed reservation, and you still need to book a slot. Check that for each site you care about before buying.

Finally, check closed days. Most major Paris museums close one day a week, and they do not all choose the same day. Building an itinerary that ignores this is the single most common Paris planning mistake.

Indian passport holders need a Schengen short-stay visa to visit France as a tourist. The application starts on the France-Visas portal and is submitted through the authorised visa application centre network, with biometrics collected in person. The general rule for choosing which country to apply to is the main destination of the trip — or, where there is no single main destination, the country of first entry — which matters on multi-country itineraries.

The supporting file typically includes travel medical insurance meeting the Schengen criteria, proof of accommodation and travel arrangements, evidence of means of support, and documents about your ties to India. Requirements are set by the authorities and are applied by the consulate, so build the file from the official checklist rather than from a forum post.

The European Union is also introducing new border and pre-travel systems that change procedures over time. Verify everything that applies to your trip on the official portals before you book non-refundable travel. A visa is permission to travel; the border officer decides admission.
