- May cost more per message
-
Toll-Free Number: 1-800-XXX-XXXX

C. Message Length and Type
Character limits and pricing impact:
-
Standard SMS (GSM-7):
- Single segment: 160 characters = 1× base rate
- Multi-part: Each 153-character segment = 1× base rate
- Example: 300-character message = 2 segments (153 + 147) = 2× base rate
-
Unicode SMS:
- Single segment: 70 characters = 1× base rate
- Multi-part: Each 67-character segment = 1× base rate
- Example: 150-character message with emoji = 3 segments = 3× base rate
Cost Optimization Tip: Keep messages under 160 characters using standard GSM-7 characters to minimize costs.
D. Time of Day and Carrier
Peak vs. Off-Peak: Some local carriers charge higher rates during business hours (8 AM – 6 PM local time).
Carrier Routing: Messages to Digicel vs. Flow may have slightly different costs due to interconnection fees.
International Routing: API providers route through different carriers, affecting delivery speed and costs.
How Carrier Routing Works: International SMS API providers maintain direct connections or aggregator partnerships with local Caribbean carriers. When you send a message to +1758, the provider's routing engine selects the optimal path based on:
- Carrier detection: Number lookup identifies whether the recipient uses Digicel or Flow
- Route quality: Providers monitor delivery rates, latency, and cost per carrier
- Failover: If the primary route fails, messages automatically route through backup carriers
Most international providers (Twilio, Plivo, Sinch, Infobip) maintain connections to both Digicel and Flow networks, ensuring comprehensive coverage regardless of recipient carrier.
Tip: Test delivery speeds with different providers during your target sending times for time-sensitive messages.
Typical Delivery Times: SMS messages to Saint Lucia typically deliver within 1 – 10 seconds under normal conditions. Factors affecting speed:
- Domestic routing (within Caribbean): 1 – 5 seconds average
- International routing (US/Europe to Saint Lucia): 3 – 10 seconds average
- Network congestion: Delivery may slow during peak hours (8 AM – 6 PM AST) and holidays (Christmas, New Year, Carnival)
- Carrier-specific delays: Flow and Digicel network maintenance windows may cause temporary delays
For critical time-sensitive messages (OTPs, alerts), budget 15 – 30 seconds for delivery and implement retry logic for failures.
