Where Your SMS Enters French Guiana: smsroute POP → Orange Caraïbe & SFR Caraïbes → Handset

French Guiana is a French overseas territory (département d'outre-mer) with 0.28 million inhabitants and 73% mobile penetration—approximately 204,000 active mobile subscribers across two primary operators. When you submit an SMS via smsroute's REST API or SMPP connection, your message enters our nearest point of presence (POP) with direct interconnect agreements to Orange Caraïbe and SFR Caraïbes. The routing path is optimized for the least-cost, highest-reliability link through the French Guiana national backbone, typically terminating at Orange Caraïbe's gateway first (owing to its 78% market dominance) with fallback to SFR Caraïbes for network redundancy.

French Guiana's telecommunications infrastructure is regulated by ARCEP (Autorité de Régulation des Communications Électroniques et des Postes), which enforces the same compliance standards as mainland France plus CNIL data protection guidance for overseas territories. E.164 standardization is strict: all mobile numbers follow the format +594 XXXXXXXX (8-digit subscriber number), with geographic or operator-specific prefixes in the first digit after the country code. Our latency budget of 248 ms (p50) and 610 ms (p95) reflects direct operator interconnect, minimal transcoding, and optimized carrier routing—typical for a territory with undersea fiber connectivity and robust French telecom infrastructure.

Delivery success of 98.2% accounts for occasional network congestion during peak hours (typically 18:00–20:00 GFT), subscriber churn, invalid numbers, and opt-out status checks. 99.9% uptime is maintained across all infrastructure, meaning your API endpoint is available for message submission 24/7, though marketing SMS are subject to quiet hours (08:00–20:00 GFT) enforced at the operator gateway.

GDPR, CNIL, and ARCEP: Consent Framework for French Guiana

French Guiana operates under European data protection law: GDPR applies in full, complemented by CNIL guidance on overseas SMS marketing. ARCEP is the telecommunications regulator and enforces both the E-Privacy Directive (via national French law) and CNIL directives. All SMS, whether transactional or marketing, must originate from a registered sender and use a valid E.164 recipient number.

Marketing SMS require explicit opt-in prior to sending. You must maintain a record of the recipient's consent (date, method, context), honor opt-out requests within 48 hours, and retain evidence of compliance for ARCEP audits. CNIL guidance specifies that pre-ticked consent checkboxes are not valid; opt-in must be affirmative and separate from other agreements. Marketing messages must be sent only between 08:00 and 20:00 GFT (UTC-3). Violations can trigger ARCEP enforcement action, including warnings, fines, and suspension of sender ID privileges.

Transactional SMS (password resets, one-time passcodes, delivery notifications, account alerts) do not require prior explicit consent but must clearly identify the sender and relate directly to a service the recipient has requested. These messages can be sent 24/7 and are not subject to quiet hours. However, the sender must still be registered with ARCEP, and the message must comply with anti-spam rules: no misleading headers, no unsolicited promotions embedded in transactional content.

smsroute enforces quiet hours at the API level: if you tag a message as "marketing," our system will queue it for delivery only during 08:00–20:00 GFT. We do not send before 08:00 or after 20:00 GFT unless the message is classified as "transactional." We do not store or audit your end-user consent logs, but we strongly recommend maintaining them yourself. ARCEP has published enforcement guidance confirming that senders bear full responsibility for opt-in records; gateways are not held liable if a sender submits non-compliant messages.

Mobile Operators in French Guiana

Orange Caraïbe (78% market share): Orange Caraïbe is the incumbent operator, owned by Orange SA (France Télécom). It operates the 2G (GSM-900/1800), 3G (UMTS-900/2100), 4G (LTE-800/1800/2600), and emerging 5G networks across French Guiana. Direct interconnect is available via Orange's international SMS gateway, with typical latency under 200 ms. Sender ID rewriting occurs if an unregistered alphanumeric ID is used; Orange may replace it with a shortcode or numeric gateway ID. A2P contracts with Orange Caraïbe require ARCEP compliance documentation.

SFR Caraïbes (22% market share): SFR Caraïbes is the alternative operator, owned by Altice Europe. It operates parallel 2G, 3G, 4G, and 5G networks with geographic overlap and competitive pricing. Interconnect with SFR is also direct, with latency typically 250–300 ms. SFR has similar sender ID registration requirements; unregistered IDs may be rewritten. smsroute's routing logic prioritizes Orange Caraïbe first (due to market share) but automatically fails over to SFR for robust coverage.

Both operators enforce ARCEP and CNIL compliance at the gateway level: incoming SMS are checked for opt-out status, quiet-hour compliance, and sender registration. Repeat violations or spam complaints can result in blacklisting of sender IDs or short codes.

How to Send SMS to French Guiana: 3 Steps

Step 1: Create Account. Navigate to smsroute.cc and sign up with your email address. No phone verification, no ID document, no corporate paperwork is required. You receive API credentials (API key, sender account ID) immediately upon signup.

Step 2: Top Up with Cryptocurrency. Pay a minimum of $5 USD equivalent using Bitcoin, USDT (TRC-20 preferred), Ethereum, Litecoin, Monero, or Solana. Do not use credit cards, bank transfers, SEPA, or PayPal—these are not supported. Your top-up is confirmed within 1–2 block confirmations, and SMS credits are credited to your account immediately. $0.0330 is deducted per SMS sent.

Step 3: Send to French Guiana. Use the REST API or SMPP connection to submit SMS. Target phone numbers must be in E.164 format: +594 followed by an 8-digit subscriber number. Example: +594 69423150 (Cayenne area) or +594 59412345 (regional). Include a pre-registered alphanumeric sender ID (max 11 Latin characters, no spaces, no special characters). Tag your message as "marketing" or "transactional" to ensure correct quiet-hour handling.

REST API Example (curl):

Python SDK Example:

Responses include a unique message ID, delivery status (queued, sent, delivered, failed), and cost in USD. Delivery status is polled via a separate endpoint or via webhook callback if configured. Failed messages are typically due to invalid E.164 format, unregistered sender ID, opt-out recipient, or network unavailability.
