Tourist attractions and suburbs
• The main attractions have basic coverage, but the signal is unstable in remote islands.
- Guadeloupe National Park: The main roads and visitor center have good 4G coverage, but signal weakens in the depths of the rainforest, requiring backup communication solutions.

Network Usage Tips
Impact of tropical storm
The Caribbean hurricane season (June-November) may cause power outages at base stations, increasing the risk of network disruptions. It is advisable to download necessary materials in places with stable power supply, such as hotels. According to ITU data, local mobile network coverage reaches 92%, but natural disasters can temporarily affect service stability.
Island terrain constraints
The mountainous terrain and scattered island structure result in uneven signal coverage, with unstable signals in Martinique's rainforests and Guadeloupe's mountainous areas. It is recommended to confirm the operator's coverage in advance.
Indoor and Historic Buildings
Colonial-era stone buildings and underground areas can significantly weaken signals; it is recommended to use the network near windows or in open outdoor areas.
Cross-border region
There may be network switching delays in the border area between the French and Dutch sides of Saint Martin. It is recommended to manually select your network in advance to ensure a stable connection.
Network congestion during peak travel seasons
During the peak winter travel season (December to March), popular islands such as Saint Barthélemy may experience network congestion. It is advisable to avoid using high-bandwidth applications during peak hours. Approximately 78% of local mobile users rely on 4G networks, where resources are relatively limited.
Language support issues
The primary language spoken locally is French, with limited English support. It is advisable to download a translation app in advance.
Battery Consumption Warning
In areas with weak signals, mobile phones continuously search for networks, leading to faster battery drain. It is recommended to carry a portable charging device. The local mobile cellular network has a high user penetration rate, but network quality varies significantly across different regions.
Data rate limit notification
After the high-speed data allowance in the package is exhausted, the speed will be reduced to 384kbps, which may affect video calls and streaming experiences. It is recommended to choose an appropriate data plan based on your travel needs. Local 3G roaming is available but has limited coverage, so ensure the use of a 4G network for the best experience.
Price Evaluation
85% of the population in the French West Indies live within 4G coverage, with a significant gap between urban and remote island areas (95% 4G coverage in cities vs. only 65% in remote islands). As an overseas territory of France, the network infrastructure is relatively well-developed, with Orange providing excellent local coverage. Mobile plan prices are comparable to mainland France but slightly higher. In urban areas, basic plans (500MB–2GB/day) suffice for daily needs, while deeper into remote islands, plans with 2GB or more are recommended to ensure uninterrupted usage. Market data shows that local mobile data prices have dropped by approximately 40% over the past five years, though network quality varies noticeably across regions. In major cities and tourist areas, 5G networks are being gradually deployed, offering users a faster and more seamless connectivity experience.
