DialAnyone calls French Guiana from $0.0155 per minute with no monthly fee and no contract, billed by the second from a credit balance. Threema is compared against that below on price, on what it takes to get started, and on whether you can hold a French Guiana number.
French Guiana numbers are voice-only wherever you buy them, so neither service can offer one that receives SMS verification codes.

Telecommunications in French Guiana
French Guiana's telecommunications infrastructure is relatively advanced, benefiting from its status as an overseas region of France. The primary mobile network operators include Orange, SFR, and Digicel, which provide coverage across most urban and rural areas. As of 2023, 4G LTE coverage is widespread, offering high-speed mobile internet access. While 5G rollout is ongoing, it is primarily available in urban centers like Cayenne and Kourou. Landline services are also accessible, although mobile phone usage is predominant, with the majority of the population relying on mobile devices for communication. According to ARCEP (the French telecommunications regulatory authority), French Guiana's mobile penetration rate is around 118%, indicating that many individuals own multiple SIM cards or devices. The robust infrastructure ensures reliable connectivity, essential for both personal and business communications in this diverse region.
Best Times to Call French Guiana
French Guiana operates on French Guiana Time (GFT), which is 3 hours behind Coordinated Universal Time (UTC-3) and does not observe Daylight Saving Time. This means that there is a time difference of 5 hours between French Guiana and Central European Time (CET). Typical daily schedules see residents awake by 6 AM, with the workday often commencing around 8 AM and concluding by 5 PM. Evenings and weekends are ideal for personal calls, as people tend to be more relaxed and available. However, it's advisable to avoid calling during lunch hours, generally between 12 PM and 2 PM. National holidays, such as Bastille Day (July 14) and local observances like the Carnival season, are also times when many residents may be unavailable. Recognizing these patterns can help ensure your calls are well-timed and appreciated.
