Monaco eSIM plans compared: HelloRoam on Monaco Telecom 5G from $30.26
HelloRoam runs Monaco on Monaco Telecom, the principality's only mobile carrier, which is why a single profile at $30.26 for 1 GB holds 5G across Monte Carlo, La Condamine, Fontvieille and Moneghetti with no handover anywhere. At 2.02 square kilometres, Monaco is the smallest country running its own mobile network. That network is independent of French Orange or SFR, so visitors arriving from France switch to Monaco Telecom to avoid roaming charges.
Coverage is dense across the Casino district, Port Hercule, and the Formula 1 street circuit.
通信範囲の分析
Monaco Telecom 5G covers 100% of the principality. Monte Carlo Casino and Casino Square have full 5G. Port Hercule and the yacht harbor signal is consistent for boat-adjacent use.
The Formula 1 Grand Prix circuit running through Sainte Devote, Beau Rivage, Casino, and Rascasse corners all sit under dense 5G coverage. The Prince's Palace on the Rock and the Oceanographic Museum have full signal. No coverage gaps exist in Monaco given the tiny geographic area.
開通方法
Monaco has no commercial airport. Visitors arrive by train to Monaco-Monte Carlo station, by helicopter from Nice Cote d'Azur Airport, or by car on the A8 autoroute. Install your eSIM before leaving Nice or your origin city, and Monaco Telecom attaches as you enter the principality with no counter visit.
A France eSIM does not cover Monaco, because the principality sits outside the EU roaming area as an independent country. iPhone XS or newer, Pixel 3a or newer, and Galaxy S20 or newer support eSIM.
データ通信の活用のコツ
Monaco day visitors use 300-500 MB for maps of the principality's steep streets, photos from Port Hercule, and restaurant lookups, which fits inside the $30.26 1 GB plan. Grand Prix weekend visitors attending the Formula 1 race in late May use 1-2 GB across race days for timing apps and clip streaming, so the $85.74 3 GB plan is the safer buy. Hotel guests on multi-night stays use 1-3 GB in total.
Download offline maps in Nice before you travel to keep live data use down.

Monaco eSIM questions answered
What is the best eSIM for Monaco?+

Which Monaco eSIM plan should I buy?+
HelloRoam prices Monaco at $30.26 for 1 GB on Monaco Telecom 5G, which covers a day trip from Nice or Cannes with maps, photos and restaurant lookups. Multi-night guests attending the Grand Prix or the Yacht Show should take the 3 GB plan at $85.74. Every plan covers the whole 2.02 square kilometre principality on 5G.
How much does a Monaco eSIM cost?+
Monaco has 6 eSIM plans on Monaco Telecom 5G. The entry tier is $30.26 for 1 GB over 7 days, and 3 GB costs $85.74. Five GB costs $134.48, 10 GB costs $245.43, and 20 GB costs $450.47 at $22.52/GB. A daily option costs $53.79. Monaco Telecom operates outside the EU single roaming market, which sets these rates.
Does my France eSIM work in Monaco?+
No. A France eSIM does not cover Monaco. The principality is an independent country with its own carrier, Monaco Telecom, operating outside the EU roaming area. French carriers such as Orange and SFR charge international roaming rates there. You need a separate Monaco plan, and Monaco plans start at $30.26 for 1 GB on Monaco Telecom 5G.
Which network does eSIM use in Monaco?+
The Monaco eSIM connects to Monaco Telecom, the principality's sole carrier, on all 6 plans. Monaco Telecom runs a 5G network covering Monte Carlo, La Condamine, Fontvieille, and the Formula 1 Grand Prix circuit. No other mobile operator exists in Monaco, so there is exactly 1 network and no fallback if it drops.
How much data do I need for a day in Monaco?+
Most day visitors use 300-500 MB for maps through the Casino district, photos from Port Hercule, and restaurant lookups. The $30.26 1 GB plan covers that with room to spare. Formula 1 Grand Prix visitors running timing apps and streaming highlights need 1-2 GB per event day, which puts them on the $85.74 3 GB plan.
How do I activate a Monaco eSIM?+
Install your eSIM QR code before arriving in Monaco. Monaco Telecom attaches as you enter the principality by train at Monaco-Monte Carlo station or by car on the A8. No counter visit and no local registration apply. Your plan starts counting from first data use on the network, and tiers run from $30.26 to $450.47.
Can I use eSIM during the Monaco Formula 1 Grand Prix?+
Yes. Monaco Telecom 5G covers the entire Formula 1 street circuit, including Sainte Devote, the Casino hairpin, and Rascasse corner. Race weekends in late May bring large crowds onto a 2.02 square kilometre footprint. Take the 3 GB plan at $85.74 for a race weekend of timing apps, photo uploads and messaging rather than the 1 GB entry tier.
Why is a Monaco eSIM expensive?+
Monaco Telecom runs as an independent carrier outside the EU roaming framework, and it is the only network in the principality. That puts the 20 GB tier at $450.47, or $22.52/GB, far above the $2.20 median across the 185 destinations priced here. Most visitors stay 1 to 3 days, so the $30.26 1 GB plan is the tier that actually gets bought.
Does eSIM cover the Monte Carlo Casino?+
Yes. Monaco Telecom 5G covers Casino Square and the Monte Carlo Casino building, and signal inside holds up given the network density across 2.02 square kilometres. The casino does not allow phone photography inside the gaming rooms. Maps and messaging work normally outside in Casino Square and on the surrounding streets on a $30.26 1 GB plan.
