Travel eSIMMonaco
Monaco is two square kilometres of harbour, rock and tower blocks folded into the French Riviera — and it is not France, and not the European Union, which is why a phone plan that worked all the way down the coast can start charging differently at the station. Install the eSIM before you set off and you are online as the train pulls in.

eSIM plans for Monaco
Online as the train pulls in
Monaco has no airport of its own. Almost everyone comes through Nice: the coastal train takes around twenty minutes to the underground station of Monaco–Monte-Carlo, a bus or taxi follows the corniche, and a helicopter does it in a few minutes. Cruise ships tie up in or anchor off Port Hercule. However you arrive, the first thing you need is a map — the principality is built in layers, and the lifts are not where you expect.
- Before you travel: buy a plan and scan the QR code at home, on Wi-Fi. It takes about a minute.
- On arrival: switch mobile data to the travel eSIM and turn data roaming on for that line.
- Your own number stays active for calls and the SMS codes from your bank. WhatsApp keeps your usual number.
Covered end to end — with a few places where the rock wins
Monaco is smaller than most city parks, and it is covered from the French border to the French border. Monte-Carlo, the harbour, the Rock, Fontvieille and the beaches all have strong 4G, and 5G is widely available.
Where the signal weakens is inside the hill itself: deep underground car parks, the long pedestrian tunnels and public lifts cut through the rock, and the lower levels of some buildings. It returns within a few steps of daylight. Out at sea the coverage follows the coast for a good distance, then thins like anywhere else.
Monte-Carlo
Casino Square, the grand hotels and the gardens above them. The busiest quarter and the best-covered, 5G included — useful, since this is where you will be looking up restaurant bookings.
Monaco-Ville — the Rock
The old town on its headland: the palace, the cathedral, the Oceanographic Museum. Strong signal in the lanes and on the ramparts; inside the thick-walled museum expect it to dip.
Port Hercule & La Condamine
The harbour, the market and the start line of the Grand Prix. Reliable all along the quays — though on race and yacht-show weekends the crowd slows every network down.
Larvotto & the eastern shore
The public beach and the seafront promenade. Good signal on the sand; this is also the end of the country, and a home SIM here may already be talking to France.
Monaco: mobile networks
Monaco Telecom5G
Surrounded by the EU. Not in it.
Monaco is a sovereign state with its own mobile network, and it is not a member of the European Union. The EU's roam-like-at-home rules do not have to apply here, so a German, Spanish or even French plan may bill Monaco as a separate destination — and British and American plans often price it differently from France as well. Some operators include it in their Europe zone, some do not, and the price list is the only way to know.
A travel eSIM takes the question away: a fixed price, paid before you leave, on a local network.
One street can be two countries
Monaco's border with France is unmarked: cross a road in Beausoleil or climb a staircase above Monte-Carlo and you have left the principality without noticing. French networks reach well inside Monaco, and Monaco's reaches out.
A home SIM with roaming on will hop between them as it pleases. Turn data roaming off on your home line and leave it on only for the travel eSIM, which stays on the Monaco network.
Race weekends and the vertical city
During the Grand Prix and the yacht show, streets close, footbridges appear and the usual walking routes stop working; live maps are worth more than the printed one. Monaco is also built upwards — public lifts and escalators link the levels, and a navigation app that knows them saves a good many stairs.
Load your tickets and bookings before you join the crowd: with tens of thousands of phones in a square mile, everything is slower.

Monaco: questions before you buy
Is Monaco covered by EU roaming?
Not automatically. Monaco is not part of the European Union, so the roam-like-at-home rules do not bind operators here. Many European operators include Monaco in their Europe zone anyway and others charge it as a separate destination — check your own price list, or use a travel eSIM and skip the question.
Does my UK or US plan work in Monaco?
Usually it will connect, by roaming — the question is the price. Some plans count Monaco with France and the rest of Europe, others list it separately at a higher rate. It depends on the operator and on the plan, so look Monaco up by name before you travel.
Does the Monaco plan work in France or Italy?
No — a Monaco plan covers Monaco. If you are staying in Nice or Menton and visiting for the day, a France plan or a regional Europe plan is the better fit; for a trip along the Riviera into Italy, choose a regional plan.
Does Monaco have 5G?
Yes — the principality is small enough to have been covered early, and 5G is available across most of it, with 4G everywhere else. Whether your plan uses it is shown on each plan's card.
Will I have signal in the train station and tunnels?
The station is underground and generally covered on the platforms and in the long exit corridors, though the signal can drop for a moment in the rail tunnels on either side. In deep car parks and some lifts expect it to disappear briefly and return at street level.
Do I need cash, and what currency is used?
Monaco uses the euro. Cards and phone payments are accepted practically everywhere, from the market in La Condamine to the beach clubs, so a data connection covers most of what cash used to.
