Monaco may be the world’s second-smallest sovereign state, but staying connected within its 2 square kilometers of glamour, hairpin turns, and harborfront skyline is anything but complicated. Because Monaco has no independent mobile spectrum authority separate from its single domestic carrier, the entire country runs on one dedicated mobile network — Monaco Telecom — supplemented by strong cross-border roaming agreements with French operators. This guide breaks down everything a visitor, business traveler, or new resident needs to know about getting a prepaid SIM card in Monaco: where to buy one, what it costs, which networks and speeds to expect, how registration works, and how eSIMs compare to a physical card.
Basics: What You Need to Know First
Monaco is not part of the European Union, but it maintains a customs and monetary union with France and shares an open border with it. This matters for connectivity because Monaco is part of neither the EU nor the EEA, but only part of a common VAT area with France, and roaming rates on most European SIM cards are not capped or regulated in Monaco the way they are between EU member states. In practice, this means:
- There is only one mobile network operator with its own antennas inside the Principality: Monaco Telecom.
- French carriers (Orange, Free Mobile, SFR, Bouygues Télécom) all provide roaming or co-location coverage in Monaco, and French providers cover Monaco too, with Orange offering the best coverage through its roaming agreement with Monaco Télécom, and Free Mobile having nearly equal coverage due to its co-location agreement with Monaco Télécom.
- Since March 2024, Monaco’s mobile network has become more harmonized, with all French mobile customers able to use the Monegasque network throughout the Principality, ensuring consistent quality of service and coverage for customers of foreign mobile networks.
- Because Monaco is squeezed into a narrow coastal gorge, French networks’ 3G and 4G signals don’t reach every corner of the Principality, and crucial spots like the harbour and railway station are covered mainly by Monaco Télécom and Free Mobile (plus public Wi-Fi).
Bottom line: if you want the most reliable signal everywhere in Monaco — including the harbour, the train station, and the underground road tunnels — a Monaco Telecom SIM (or an eSIM riding on its network) is the safest bet.
Availability
Prepaid connectivity in Monaco is readily available, but options are narrower than in larger countries because there’s just one local network operator. Travelers generally have three realistic paths:
- A Monaco Telecom SIM or top-up, purchased locally.
- A French carrier’s prepaid SIM (Orange, Free Mobile, SFR), bought just across the border in Nice, Beausoleil, or Menton before entering Monaco, which roams onto the Monegasque network.
- A travel eSIM or global tourist SIM, purchased online before arrival, provisioned for Monaco/France coverage.
Note that Monaco Telecom itself has scaled back traditional prepaid retail offers in recent years in favor of postpaid “forfait” plans and data-only travel SIMs, so purchasing a SIM from Orange, Free, or another provider offering discount roaming on Monaco Telecom is often cited as the most economical option for short stays. That said, tourist-oriented prepaid and data SIM cards are still actively sold through kiosks, airport counters, and online SIM retailers targeting the Monaco/French Riviera market.
Where to Buy
You can pick up a prepaid SIM or eSIM for Monaco through several channels:
- Monaco Telecom retail boutiques — the two main stores are in Monte-Carlo and Fontvieille. The main store is located at 30 Boulevard des Moulins in the Monte-Carlo commercial district, with a second location at 9 Rue du Gabian in the Fontvieille area.
- Authorized resellers and mobile phone shops — <many retailers in Monaco sell physical SIM cards, including cell phone stores, kiosks, and convenience stores, found in almost all market streets and near the airport transfer points (Monaco has no airport of its own; most travelers arrive via Nice Côte d’Azur Airport).
- Nice Côte d’Azur Airport (France) — a practical stop for travelers flying in, since French carrier kiosks sell SIMs that roam well onto Monaco Telecom’s network.
- Online travel SIM and eSIM retailers — companies such as Airport Telecom, Yesim, Airalo, and similar platforms sell Monaco-ready SIM cards and eSIMs that can be ordered and, in the case of eSIMs, activated before you even leave home.
- Hotel concierge desks — many Monte-Carlo hotels can point guests to the nearest Monaco Telecom boutique or arrange a SIM on request.
Safety tip: buying a SIM card at the airport is almost always safe, and it’s best to seek out reputable outlets affiliated directly with local carriers to avoid being sold an overpriced or unofficial SIM.
Frequencies
Monaco Telecom operates a compact but modern band plan across 2G, 3G, 4G, and 5G. Here’s what your device needs to support for full compatibility:
| Technology | Frequency Bands (MHz) | Notes |
|---|---|---|
| 2G (GSM) | 900 / 1800 | Standard European 2G bands |
| 3G (UMTS) | 900 / 2100 | Dual-band 3G coverage |
| 4G (LTE) | 800 (Band 20), 2600 (Band 7), 1800 (Band 3) | 4G LTE launched in October 2013 on Band 7 (2600 MHz), with Bands 3 and 20 added in January 2015 |
| 5G (NR) | n78 (3.5 GHz) | 5G network launched in July 2019 using mid-band 3.5 GHz n78 |
Because Monaco’s mobile footprint uses standard European LTE/5G bands, virtually any unlocked phone bought in Europe — and most global unlocked flagship phones — will work without issue. If you’re bringing a device sourced from the US or Asia, double-check that it supports Band 20 (800 MHz) and Band 7 (2600 MHz) LTE, since these are the workhorse bands for indoor and tunnel coverage in Monaco’s dense urban terrain.
Coverage & Speed
Monaco’s small footprint and dense infrastructure investment mean coverage is close to universal, and 5G availability is unusually high for a microstate.
| Metric | Details |
|---|---|
| Network type | Monaco Telecom: sole domestic mobile network operator |
| 2G/3G/4G coverage | Near-100% across the Principality |
| 5G coverage | Full outdoor coverage since the July 2019 launch</cite>, expanding indoors in central districts |
| Typical 4G download speed | 30–80 Mbps in most areas |
| Typical 5G download speed | 150–400+ Mbps in 5G-enabled zones (varies by device and location) |
| Known weak spots | Underground tunnels and some French-carrier-only zones near the harbor and rail station, where only Monaco Télécom and Free Mobile maintain reliable signal |
| Roaming partner network | Orange France (reciprocal no-surcharge roaming agreement) |
For the most consistent real-world speeds, especially around the harbor, Casino Square, and the train station, a SIM running natively on Monaco Telecom (rather than a roaming French SIM) will generally outperform alternatives.
At a Glance: Comparison Table
| Option | Best For | Approx. Cost | Data Included | Registration Needed |
|---|---|---|---|---|
| Monaco Telecom prepaid/travel SIM | Best local coverage, longer stays | €10–€20 for the SIM + data add-ons | Varies by add-on | ID document required |
| French carrier SIM (Orange, Free, SFR) bought near the border | Budget travelers, short trips | Often cheaper, comparable roaming | Bundle-dependent | ID document required |
| Tourist/travel physical SIM (Airport Telecom, etc.) | Convenience, pre-trip planning | 3GB and 6GB data bundles available | 3–6 GB typical | Minimal, often none |
| eSIM (Airalo, Yesim, etc.) | No physical SIM swap, instant activation | $9.50–$26 for 1–3 GB | 1–3 GB typical, scalable | None (digital only) |
| Monaco WiFi (public network) | Supplement to mobile data | Free (2-hour Discovery Pass) or paid daily/weekly rate | N/A (WiFi, not SIM) | Login/registration on portal |
Biometric User Registration
Unlike some countries that require fingerprint or facial biometric capture for SIM registration, Monaco does not currently mandate biometric enrollment for prepaid SIM purchases. Registration is identity-document based rather than biometric: you present a valid passport or national ID card, and the retailer records your identity details against the SIM. If regulations change, Monaco Telecom boutiques and its official website (monaco-telecom.mc) would be the authoritative source to confirm current requirements before your trip — it’s worth a quick check if biometric verification becomes standard practice across Europe, since Monaco often aligns select telecom practices with neighboring French and EU norms even though it isn’t a member state.
Device Registration
Monaco does not operate an IMEI blacklist/registration scheme comparable to those found in some markets. Any unlocked, band-compatible phone can be used with a Monaco Telecom SIM without a separate device registration process. What is required is proof of identity when purchasing the SIM itself:
- A valid identity document — passport or national ID card — plus proof of address in Monaco is required to obtain a SIM card from a Monaco Telecom retail store.
- Visitors without a Monegasque address can typically still purchase a tourist-oriented SIM or data package, though residents with a Monegasque address will have the smoothest registration experience, and non-residents purchasing longer-term plans may be redirected toward prepaid/travel-specific products rather than standard resident SIMs.
- Activation is typically completed the same day the SIM is purchased in-store.
SIM Card Price
Prepaid SIM pricing in Monaco is straightforward but sits on the higher end compared to many European countries, reflecting the Principality’s overall cost of living.
- The cost of a SIM card in Monaco typically ranges from EUR 10 to EUR 20, depending on the provider and the included benefits, with data plans purchased separately to suit specific usage requirements.
- Data plans typically start from around EUR 5 for smaller bundles, with larger data volumes available at higher price points.
- For eSIM buyers, once-off prices for eSIM plans covering Monaco range from roughly $9.50 to $26, including between 1 GB and 3 GB of data.
- Physical tourist SIMs from specialist retailers commonly bundle 3GB or 6GB data allowances as flat-rate travel packages rather than pay-per-MB pricing.
Top-Up Methods
Recharging a Monaco Telecom (or partner) prepaid SIM can be done through several convenient channels:
- In-store top-up at any Monaco Telecom boutique or authorized reseller, by cash or card.
- Official website top-up, using a credit or debit card, for account holders with an online profile.
- Mobile app top-up, through Monaco Telecom’s customer account app (where available), letting you reload credit or purchase data add-ons from your phone.
- Retail voucher/scratch cards, sold at convenience stores, newsagents, and telecom kiosks, redeemed by entering a code via SMS or USSD.
- Bank transfer or direct debit, typically used for postpaid or hybrid plans rather than pure prepaid.
Always check the expiry window on your top-up, since unused prepaid credit and data can lapse after a set validity period (commonly 30 days for standard bundles, longer for larger travel packages).
Monaco Telecom
Monaco Telecom is the sole domestic mobile, fixed-line, and internet operator serving the Principality, and it plays the same central role that a country’s national “primary carrier” would elsewhere. Key facts:
- Monaco Telecom was established in 1997, when the Monaco government privatized the formerly state-controlled Office Monégasque des Téléphones.
- Ownership is jointly held between Iliad — the investment vehicle of French entrepreneur Xavier Niel — and the Société Nationale de Financement, an entity wholly owned by the Monegasque government.
- Monaco Télécom maintains a reciprocal roaming agreement with Orange in France, allowing users of either network to roam onto the other without surcharges
- The company operates Monaco’s fixed broadband, mobile network, TV, and the free public Monaco WiFi hotspot service, and it remains the only operator with physical mobile antennas inside the country’s borders.
For visitors, this means Monaco Telecom isn’t just “an option” — it’s the backbone network that even foreign SIMs ultimately roam onto when signal from cross-border towers doesn’t reach.
Monaco Telecom Prepaid Plans
Monaco Telecom’s consumer plan lineup leans primarily toward postpaid subscriptions, with prepaid and travel-oriented data packages positioned as the pay-as-you-go alternative for tourists and short-term visitors.
- Entry-level monthly plans start from approximately 20 euros and include a reasonable data allowance with unlimited calls and texts within Monaco and to France.
- Mid-range plans offering larger data packages of 50–100 GB, plus additional international calling minutes, typically cost between 30 and 50 euros monthly.
- Premium plans with very large or unlimited data allowances are available at higher price points
- Prepaid SIM cards remain available for those who prefer pay-as-you-go arrangements, though they carry higher per-unit costs for calls and data compared with postpaid plans.
- Roaming in France is included at no extra cost in most Monaco Telecom plans — a significant advantage given how often Monaco residents cross into neighboring France.
Because plan details and pricing are periodically updated, always confirm current prepaid offer terms directly with a Monaco Telecom boutique or the official website before purchase.
Data Add-Ons
For travelers who prefer a base SIM plus flexible data top-ups rather than a full monthly plan, data-only add-on bundles are the most popular route.
| Add-On Size | Typical Use Case | Approx. Starting Price | Validity |
|---|---|---|---|
| Small (≈1 GB) | Light browsing, messaging, maps | From ~€5 / ~$9.50 | 7–30 days |
| Medium (3 GB) | Email, WhatsApp, navigation, general app use | Mid-range tourist SIM pricing | Trip-length validity |
| Large (6 GB) | Heavier data users, streaming, extended browsing | Higher tourist SIM pricing | Trip-length validity |
| Extended eSIM bundles | Multi-country trips including Monaco/France | Up to $26 for higher-tier eSIM data plans | Set by provider, often 15–30 days |
Data add-ons are usually purchased in-store, via the operator’s official app or website, or bundled directly into a travel SIM/eSIM at the point of sale — no separate top-up needed for pre-bundled tourist products.
Activation Codes
Activation for a Monaco Telecom SIM purchased in-store is typically completed by staff on the spot using your registered identity document, so most retail buyers won’t need to enter an activation code manually. For SIMs and eSIMs bought online or from third-party travel SIM providers, activation generally follows one of these paths:
- USSD/SMS activation code, sent by text message once the SIM is inserted and connects to the network for the first time.
- QR code activation, used for eSIMs — scan the code provided by your retailer to download and install the eSIM profile.
- App-based activation, where you enter a reference or order number in the provider’s app to trigger activation remotely.
- Automatic activation, common with prepaid travel SIMs, which activate on first network connection without any code entry.
If a code doesn’t work, contact your retailer’s support line (see the helpline section below) rather than attempting repeated manual entries, since some activation codes are single-use and can lock after failed attempts.
How to Check the Remaining Balance
Keeping track of remaining credit and data is simple through any of the following methods:
- USSD dial code: dialing a short balance-check code (provided at the point of sale or on your SIM packaging) returns your remaining credit and data instantly.
- SMS balance check: sending a specific keyword by text message to a designated short number.
- Online account portal: logging into your Monaco Telecom customer account on the official website to view real-time usage.
- Mobile app: checking balance, data usage, and expiry dates directly from the operator’s customer app.
- Customer service call: contacting support and providing your SIM/account number for a manual balance check.
Official Websites (with Link)
- Monaco Telecom official site: https://www.monaco-telecom.mc
Always verify balance-check codes and self-service tools directly on the official website, since USSD codes and portal features can be updated by the operator.
App (with Links)
Monaco Telecom offers a customer account app for managing your line, checking balances, and topping up. Search “Monaco Telecom” in the Apple App Store or Google Play Store to find the current official app listing, and confirm the developer name matches Monaco Telecom before downloading, since imitation apps can appear in app store search results.
- Apple App Store: search “Monaco Telecom” at https://apps.apple.com
- Google Play Store: search “Monaco Telecom” at https://play.google.com/store
How to Check the SIM Number
To find your Monaco Telecom SIM/phone number:
- Check the SIM packaging or card tray — the number is often printed directly on the plastic SIM carrier you punched the chip out of.
- Dial a self-check USSD code — many operators support a short code that returns your own number via SMS.
- Check your phone’s settings — under mobile network or SIM settings, some devices display the stored number automatically (though this field is sometimes blank on prepaid SIMs until manually entered).
- Check your welcome SMS — the first text message received after activation typically confirms your assigned number.
- Ask via customer support if none of the above work — Monaco Telecom support can confirm the number linked to your account/ID.
Tourist SIM
Given the constraints of Monaco Telecom’s traditional postpaid-first lineup, most short-trip visitors opt for a dedicated tourist SIM rather than a standard resident SIM. These are purpose-built for travelers and typically bundle:
- A flat data allowance (commonly 3GB or 6GB rather than pay-per-MB billing.
- 4G/5G connectivity for fast access to email, messaging apps, navigation, and other everyday internet use</cite>.
- Minimal or no registration formalities compared to resident SIMs.
- Support for internet-based calling apps like WhatsApp, Skype, and FaceTime, drawing from the same data bundle.
Tourist SIMs are sold both locally (at kiosks, phone shops, and some hotel desks) and online in advance of your trip, making them the most convenient option for anyone who doesn’t want to deal with in-person ID registration on arrival.
Roaming Data
Because Monaco isn’t in the EU, its roaming landscape differs from intra-EU travel:
- Roaming rates on most European SIM cards are not capped or regulated in Monaco, so charges can be significantly higher than roaming within the EU itself.
- Some EU carriers voluntarily extend EU-style roaming rules to Monaco, but most do not, and apply higher surcharges instead. Check your home carrier’s specific Monaco roaming policy before relying on it.
- Travelers holding a French SIM generally get the smoothest roaming experience, since Orange’s roaming agreement with Monaco Télécom and Free Mobile’s co-location agreement both provide strong in-country coverage without the surcharges other foreign networks might apply.
- If your home carrier doesn’t offer favorable Monaco rates, a local prepaid SIM, tourist SIM, or eSIM will almost always be cheaper than paying international roaming fees for the duration of your stay.
Digital eSIM Providers
eSIM technology has become the fastest-growing way to get connected in Monaco, especially for short trips where avoiding a physical SIM swap matters.
- While eSIM technology is gaining popularity globally, it may not yet be widely available directly through Monaco Telecom itself — most eSIM coverage for Monaco instead comes through international eSIM marketplaces.
- Popular digital eSIM providers covering Monaco include Airalo, Yesim, and similar global travel eSIM platforms, which package Monaco under either standalone or regional Europe/France-inclusive plans.
- These eSIM plans let travelers avoid roaming fees, skip a physical SIM card entirely, keep their original phone number active for calls and apps like WhatsApp, and install everything with one-click activation before or after arrival.
- The Airalo app in particular allows travelers to install, activate, and top up eSIM data plans directly from their phone.
- Pricing for eSIM data in Monaco generally starts under $10 for entry-level bundles and scales up based on data volume and validity period.
Requirement: an eSIM-compatible phone (most flagship smartphones released in the last several years support eSIM) is necessary — if your device only supports physical SIMs, a physical adapter product or a traditional prepaid SIM is the better route.
Other Options
Beyond a traditional SIM or eSIM, a few supplementary connectivity options exist for visitors to Monaco:
- Monaco WiFi (public network) —launched in 2017 via Monaco Telecom, giving residents and tourists free connectivity across 26 hotspots citywide, built on a dedicated fibre optic network. Access is free for Monaco Telecom customers, and a two-hour “Discovery Pass” is offered free to any new user, which can be stopped and restarted by logging off and back on— enough for many day-trippers.
- Portable WiFi hotspots (MiFi devices) —these connect via WiFi rather than a SIM slot, letting multiple devices (laptops, tablets, smartwatches) share one connection without individual device compatibility concerns</cite>.
- Hotel and venue WiFi — free WiFi is widely available in hotels, restaurants, cafes, and public spaces across Monaco, though a local SIM remains valuable for connectivity outside those zones.
- International roaming through your home carrier — an option, though typically more expensive than a local SIM or eSIM purchased specifically for the trip.
Activation Help Line Numbers
For activation issues, balance questions, or SIM troubleshooting:
- Monaco Telecom customer service: available through their dedicated support teams for resolving SIM card issues — contact details and current hotline numbers are listed on the official site at https://www.monaco-telecom.mc.
- Third-party tourist SIM/eSIM providers: check the order confirmation email or provider app for a dedicated support line or live chat, since numbers vary by vendor (Airalo, Yesim, Airport Telecom, etc.).
- In-store support: visiting the Monte-Carlo (30 Boulevard des Moulins) or Fontvieille (9 Rue du Gabian) boutique in person is often the fastest way to resolve activation problems for SIMs purchased locally.
Because official helpline numbers can change, always confirm the current contact number through the operator’s official website rather than relying on numbers found in third-party guides.
Conclusion
Staying connected in Monaco is easy once you understand the landscape: one dominant local network (Monaco Telecom) backed by strong roaming ties to French carriers, near-total 4G/5G coverage packed into a tiny footprint, and a growing range of tourist-friendly prepaid SIMs and eSIMs designed specifically for short visits. For most travelers, the simplest approach is a tourist SIM or eSIM bundled with 3–6GB of data, picked up before arrival or from a kiosk on the ground — while longer-term residents will get better value from a Monaco Telecom postpaid plan with included France roaming. Whichever route you choose, verify current pricing, registration requirements, and helpline details directly with the operator or your chosen retailer before you travel, since telecom offers in Monaco — as everywhere — are updated periodically.
