France's network is fine. The kiosk model is not.
France is well wired — 5G across the major cities, dense LTE through the rural Loire and the Côte d'Azur, working signal in the Paris Métro. The country isn't where the trouble is. The trouble is the layer between you and the network: a roaming pass priced for the worst-case traveler, an airport SIM counter that wants your passport and forty minutes, or a "vacation plan" with a 5 GB cap printed in 6-point type.
Roamzy charges $2.66 per gigabyte in France. That's $0.0026 per megabyte, billed in real time as your phone uses data on French networks. No subscription. No expiry on the unused balance. No minimum bundle. One per-MB rate across 192 countries — that's the shape of the invoice, not a marketing line.
How much will Roamzy actually cost on this trip?
A typical visitor uses 0.7–1.5 GB per day in France: Google or Apple Maps to a hotel, the camera-translator on a brasserie menu, Bolt or Heetch around the city, the SNCF Connect app for TGV bookings, Deliveroo for Sunday-night dinner, contactless payments through your bank app, the occasional video call back home. Call it 1 GB/day for the math:
| Trip length | Roamzy ($2.66/GB) | Tourist roaming pass | Airport local SIM |
|---|---|---|---|
| 3 days | $7.98 | $15–40 | $10–25 + paperwork |
| 1 week | $18.62 | $25–60 | $15–30 + paperwork |
| 2 weeks | $37.24 | $40–100 (often two passes) | $20–35 + 30-day cap |
Competitor prices in columns 3 and 4 are 2025 ranges based on typical offerings; exact figures depend on your home carrier and the airport store you visit. Roamzy's rate in column 2 is our actual published rate from the pricing page.
An airport SIM at €15–25 looks reasonable in the abstract. In practice you queue at CDG or Orly with everyone else who just landed, present your passport, sit through a brief KYC, then pay in cash or with a French card. The eSIM removes that step: pre-installed at home, attached the moment you're on French ground.
Why is per-megabyte pricing simpler than packages?
Travel is already cognitive load. A new alphabet of train stations, a card your bank silently flagged on the first €40 charge, a dinner reservation in a language you half-learned. The data plan is the part that should be solved before the flight.
Roamzy is built around that. No first-purchase promo to lure you, then jacked rates on the second top-up. No fine-print throttling — "5 GB at full speed, then 128 kbps." No auto-renewal you forgot to cancel and discover six months later. One rate, billed by the megabyte, balance carries. Spent 380 MB walking the Marais? You paid $0.99. Today on hotel Wi-Fi reading? You paid nothing.
This isn't a feature, it's an engineering preference for not having features. You can't price below this without re-introducing the small print, so we don't.
Where does Roamzy work in this country?
France is an EU telecoms front-runner. The picture on the ground:
- Paris, Lyon, Marseille, Bordeaux, Lille, Strasbourg — 5G in the centers, providers compete on quality more than coverage
- Mid-size cities (Nice, Toulouse, Nantes, Rennes) — solid LTE, 5G in central districts
- The Riviera, the Loire châteaux, Normandy beaches — clean LTE through the tourist corridors
- TGV between cities — near-continuous signal end to end; brief drops in long tunnel sections
- Paris Métro and RER — working signal on platforms and most tunnel runs
Rural cellular dead zones aren't really a French problem. If you're hiking the high Alps or deep in the Pyrenees, expect spotty 4G — GPS plus offline maps handle that.

What are Roamzy's honest limitations?
Three traps Roamzy doesn't have because they were never built in.
- No welcome promo that bait-and-switches your second top-up. The rate on top-up #1 is the rate on top-up #20.
- No fine-print throttling that surfaces on the third day. One rate, full speed — first GB and the hundredth cost the same $0.0026/MB.
- No auto-renewal you forgot to cancel. Balance runs out, the eSIM stops. No background charge to a card you'd already moved on from.
It's not a marketing gimmick — it's an engineering decision born from indifference to gimmicks. You can't make a tariff cheaper than no fine-print and no expiry — so we don't.
What if my trip continues to other countries?
Roamzy is for the traveler, not the resident. The same rate logic applies the moment you cross a border:
- Spain — south-bound through the Pyrenees, eSIM hands over without you touching a setting
- Italy — over the Alps or by TGV from Paris, separate country rate
- Germany — common business extension via TGV from the east
- If you want the underlying mechanics — how roaming actually gets priced and why it hurts
