Pay-per-use cost audit
What AT&T charges per activity in Monaco — no day pass
One day in Monaco without an international plan: typical phone use runs roughly 450 MB. At AT&T's $2.05/MB pay-per-use rate, that day costs $922. Breakdown: 1 hour of navigation ($102), 30 minutes of Zoom ($922), uploading 20 photos ($410), light social media. One day with a Monaco eSIM on Monaco Telecom: roughly $4.32 when you spread the plan cost across your trip. AT&T's International Day Pass is $12/day and avoids pay-per-use entirely — but even that costs more than most eSIM plans cover for the same period. Source: AT&T rate card, June 2026.

Network coverage
4G and 5G network reach across Monaco
Monaco has one mobile operator: Monaco Telecom. AT&T, Verizon, and travel eSIM providers all route through Monaco Telecom. There is no network variable to compare — only price. AT&T: $10/day. eSIM: $22.52/GB. The network connection is the same. The price is not. 5G coverage is available on Monaco Telecom in Monaco's main cities. Carrier roaming and eSIMs connect to 5G equally in those areas. Paying AT&T's $10/day roaming rate buys no additional access to those 5G towers.

Airport options
First-day data options in Monaco
Buying a SIM card at the airport in Monaco means waiting in line after a long flight, handing over your passport, and paying a tourist-markup price. A 1GB eSIM at $30.26 installs in 2 minutes from the provider's app. It activates on Monaco Telecom's network the moment you turn off airplane mode.
Data planning
Planning your data usage in Monaco

Quick reference
Monaco Travel Essentials
112/17/18/15
112, 17, 18, 15 are the emergency numbers in Monaco. Different numbers may route to different services — save all of them before your trip. Emergency calls work from any mobile device, including travel eSIMs.
Type C/E/F
Monaco uses Type C outlets (European two round-prong). US plugs require a Type C adapter. Check that your phone and laptop chargers show 100-240V input — most modern chargers are compatible.
CET/CEST (UTC+1/+2)
EUR (€)
Cash in EUR is preferred across most of Monaco outside major hotels and tourist centers. Card terminals are not common in local markets or small restaurants. Withdraw enough cash at a reliable ATM before leaving the city — rural areas may not have ATM access.
Quick tip
Monaco uses EUR (€). eSIM plans charge in USD at the time of purchase — you lock in the cost before travel and avoid in-country exchange rate moves.
Good to know
Monaco uses Type C/E/F power sockets. A dead phone means a dead eSIM connection — pack the right adapter to keep your device charged between venues.

Last-minute eSIM options for Monaco arrivals
You landed in Monaco without an eSIM. Here is what that costs and what you can still do.
All four major providers — Airalo, Holafly, Saily, and Nomad — allow post-arrival purchase and installation over WiFi. You do not need a local SIM to buy an eSIM. Most international airports in Monaco have free WiFi in arrivals. Connect there, open Airalo or Holafly, and install a 1GB plan at $30.26 before you leave the terminal. If airport WiFi is unavailable, hotel lobby WiFi works as a fallback — most front desks in Monaco give you the password at check-in. Last resort: turn on carrier data long enough to download the eSIM provider app (~5 MB, roughly $10 on AT&T pay-per-use), then switch to the installed eSIM immediately. That one-time charge is far below a full day at AT&T's $12/day rate.
Monaco FAQ
Monaco eSIM & roaming questions
How much does carrier roaming cost in Monaco?
A family of four on AT&T in Monaco pays $40/day ($10/day per line x 4). Over a week that reaches $280. The same family shares one travel eSIM on Monaco Telecom starting at $30.26 for 1GB — a single purchase covers all devices through tethering. Verizon charges the same per-line rate. T-Mobile includes free data at 256 Kbps, which cannot load a map.
Is T-Mobile's free international data fast enough in Monaco?
No. At 256 Kbps, T-Mobile's free international tier in Monaco cannot load a map tile in under 15 seconds. Video calling needs 2 Mbps minimum — eight times what T-Mobile provides for free. Their paid speed upgrade runs $15/day. A 5G eSIM on Monaco Telecom at $22.52/GB gives you real speeds without the daily fee.
How is my roaming bill calculated in Monaco?
At 3 days in Monaco: AT&T costs $30, eSIM costs 1GB for $30.26. At 7 days: AT&T $70, eSIM same 1GB for $30.26. At 14 days: AT&T $140, eSIM same fixed rate. The eSIM billing model is flat — the longer the trip, the wider the gap. T-Mobile free tier is $0 but too slow at 256 Kbps to be usable beyond text.
Can I use my Apple Watch cellular in Monaco with a travel eSIM?
Apple Watch Series 4 and later support eSIM, but international travel eSIM providers do not sell standalone Apple Watch plans. The Apple Watch in Monaco connects via your iPhone's hotspot — it mirrors the iPhone's data connection. Your iPhone must have an active plan (carrier roaming at $10/day or a travel eSIM at $22.52/GB on Monaco Telecom) for the Watch to function away from WiFi. Apple Watch Cellular uses your watch's built-in eSIM only on your home carrier — AT&T and Verizon charge per watch line at the same daily roaming rate in Monaco. Rates checked June 2026.
What is the best data plan for a 1-month stay in Monaco?
For a 30-day trip at 1.5 GB/day average, total usage runs 45 GB. AT&T International Day Pass: $300 for the month. T-Mobile high-speed add-on: $450. A travel eSIM on Monaco Telecom at $22.52/GB for 45 GB costs roughly $1013.40. For stays over 2 weeks, also consider a local SIM purchased in Monaco — local prepaid cards often run $10-25 for 20-50 GB at full local speeds with no international markup. Rates checked June 2026.
Does EU roaming cover Monaco for US travelers?
No. EU roaming is a rule for European carrier customers — US carriers (AT&T, Verizon, T-Mobile) are not subject to it. All three US carriers charge their standard international rates in Monaco: AT&T at $10/day, Verizon at $10/day, T-Mobile free at 256 Kbps. A travel eSIM cuts through the complexity — $22.52/GB on Monaco Telecom's 5G network, no EU policy considerations required.
Is AT&T International Day Pass cheaper than an eSIM for Monaco?
No. AT&T International Day Pass costs $10/day in all European countries including Monaco. Over 7 days that is $70. A 5GB eSIM plan costs $134.48 for the same period on Monaco Telecom. The eSIM saves -92% and does not charge you on days when you only use WiFi — unlike the day pass, which triggers the moment any cellular data is used.
Can I use one eSIM across multiple European countries including Monaco?
Yes. Multi-country European eSIM plans cover the Schengen Area — typically 30+ countries including Monaco — under a single data bucket. AT&T and Verizon roaming rates are the same in every Schengen country: $10/day per country. A regional eSIM buys you data that works across borders without activating per-country charges. If your itinerary includes Monaco plus 2-3 neighboring countries, the regional eSIM is cheaper than day passes for every country crossed.
Does GDPR affect the data collected by a travel eSIM in Monaco?
GDPR governs how companies process personal data, not how your phone uses mobile data. A travel eSIM in Monaco connects to Monaco Telecom's network — the same infrastructure AT&T and Verizon route roaming through. GDPR does not change connection speeds, pricing, or data limits. Both carrier roaming and travel eSIMs log metadata (connection times, data volumes) as part of standard carrier operations. GDPR applies to the provider's handling of that log data, not to your browsing or usage.
How much does carrier roaming cost for a week in Monaco?
AT&T: $70/week (International Day Pass at $10/day). Verizon: $70/week (TravelPass). T-Mobile: free at 256 Kbps or $105/week for usable speed. The cheapest eSIM for Monaco starts at $22.52/GB on Monaco Telecom's 5G network — better per-GB value than all three carriers.
Fact check
eSIM and roaming misconceptions for Monaco travelers
T-Mobile includes free international data
T-Mobile's free tier is capped at 256 Kbps in Monaco — too slow to load a map tile or stream a 30-second clip. Their high-speed add-on costs $5–$15/day depending on destination. Exception: Mexico and Canada get full LTE/5G speed at no charge under the USMCA agreement. Monaco is not on that list. Rates checked June 2026.
Carrier roaming is more reliable than an eSIM
Reliability is determined by the local carrier's network, not the billing layer above it. AT&T roaming in Monaco routes through Monaco Telecom. A travel eSIM also routes through Monaco Telecom. Both connections depend on Monaco Telecom's coverage in any given area. AT&T charges $10/day for a connection with zero reliability advantage over the $30.26 eSIM.
Pay-per-use international data rates are reasonable
AT&T's pay-per-use international data rate is $2.05/MB without an active plan. At that rate, 1 GB costs $2,050. A single Google Maps navigation session in Monaco loads 50–100 MB — that is $100–$205 at pay-per-use. A 1GB eSIM on Monaco Telecom costs $30.26 for the same data. Always activate a day pass or eSIM before your flight. Rates checked June 2026.
