Factors Influencing SMS Costs

Several factors impact SMS costs:

• Geographic Location: International messaging incurs routing costs and regulatory requirements.
• Message Volume: Higher volumes typically unlock discounts. Example: Increasing from 5,000 to 50,000 messages/month can reduce per-message cost by 20 – 40%.
• Technical Requirements: API integration complexity, delivery reports, and platform reliability can influence pricing.

Character Encoding Costs:

SMS pricing is heavily influenced by character encoding and message length:

• GSM-7 Encoding (Standard):

  • Uses 7-bit character set (Latin alphabet, numbers, basic punctuation)
  • Supports 160 characters per SMS segment
  • Cost: Base rate (e.g., $0.06/segment)
  • Best for: English text without special characters
  • Supported characters: A-Z, a-z, 0-9, @£$¥èéùìòÇØøÅåΔ_ΦΓΛΩΠΨΣΘΞÆæßÉ!"#¤%&'()*+,-./:;<=>?¡ÄÖÑÜäöñüà

• Unicode (UCS-2) Encoding:

  • Uses 16-bit character set (supports emoji, non-Latin scripts)
  • Supports only 70 characters per SMS segment
  • Cost: Same base rate per segment (but fewer characters per segment = more segments)
  • Best for: Emoji, Arabic, Chinese, Cyrillic, accented characters not in GSM-7
  • Cost Impact: A 160-character message in Unicode requires 3 segments vs. 1 in GSM-7, tripling cost

Long Message (Concatenated SMS) Costs:

When messages exceed single-segment limits, they are split into multiple segments:

• GSM-7 Multi-Segment:

  • First segment: 153 characters (7 chars used for concatenation headers)
  • Additional segments: 153 characters each
  • Cost: Charged per segment. A 200-character GSM message = 2 segments = 2× cost

• Unicode Multi-Segment:

  • First segment: 67 characters (3 chars used for concatenation headers)
  • Additional segments: 67 characters each
  • Cost: Charged per segment. A 140-character Unicode message = 3 segments = 3× cost

Real-World Cost Examples:

• 100-character English message (GSM-7): 1 segment = $0.06
• 200-character English message (GSM-7): 2 segments = $0.12
• 100-character message with emoji (Unicode): 2 segments = $0.12
• 200-character message with emoji (Unicode): 3 segments = $0.18

Character Limit Optimization Tips:

• Avoid emoji and special characters when possible to use GSM-7
• Keep messages under 160 characters (GSM-7) or 70 characters (Unicode) to minimize costs
• Use URL shorteners for links to save characters
• Test messages with different character sets before bulk sending

Practical Implementation Guide

Quick Start: Sending SMS via API (Python Examples)

Twilio Example:

from twilio.rest import Client

# Your Account SID and Auth Token from twilio.com/console
account_sid = 'YOUR_ACCOUNT_SID_HERE'
auth_token = 'YOUR_AUTH_TOKEN_HERE'
client = Client(account_sid, auth_token)

message = client.messages.create(
    to='+592XXXXXXX',  # Guyana number in E.164 format
    from_='+1XXXXXXXXXX',  # Your Twilio number
    body='Hello from Guyana!'
)

print(f'Message SID: {message.sid}')
print(f'Status: {message.status}')

Plivo Example:

import plivo

client = plivo.RestClient('YOUR_AUTH_ID_HERE', 'YOUR_AUTH_TOKEN_HERE')

response = client.messages.create(
    src='+1XXXXXXXXXX',  # Your Plivo number
    dst='+592XXXXXXX',  # Guyana number
    text='Hello from Guyana!',
    url='https://yourdomain.com/delivery_webhook'  # Optional webhook
)

print(f'Message UUID: {response.message_uuid[0]}')

Error Handling Best Practices:

from twilio.rest import Client
from twilio.base.exceptions import TwilioRestException
import time

def send_sms_with_retry(to, body, max_retries=3):
    client = Client(account_sid, auth_token)

    for attempt in range(max_retries):
        try:
            message = client.messages.create(
                to=to,
                from_=from_number,
                body=body
            )
            return {'success': True, 'sid': message.sid}

        except TwilioRestException as e:
            if e.status == 429:  # Rate limit
                time.sleep(2 ** attempt)  # Exponential backoff
                continue
            elif e.code == 21211:  # Invalid 'To' number
                return {'success': False, 'error': 'Invalid number'}
            else:
                raise

    return {'success': False, 'error': 'Max retries exceeded'}

Guyana SMS Pricing FAQ

Q: Do I need a Guyana phone number to send SMS to Guyana?

A: No. International API providers let you send from their numbers or short codes. However, local Guyana numbers may improve delivery rates and reduce costs with some carriers.

Q: How do I format Guyana phone numbers for SMS APIs?

A: Use E.164 format: +592 (country code) + XXX (area code) + XXXX (subscriber number). Example: +5922121234 for Georgetown.

Q: What's the maximum SMS length I can send?

A: Single segment: 160 characters (GSM-7) or 70 characters (Unicode). Longer messages are automatically split into multiple segments (up to 1,530 characters for GSM-7, 670 for Unicode) with concatenation headers. Each segment is charged separately.

Q: How long are SMS messages stored if delivery fails?

A: Most providers retry for 24 – 72 hours. Twilio: 72 hours, Plivo: 72 hours, local carriers: typically 48 hours.

Q: Can I send SMS from toll-free numbers to Guyana?

A: Support varies by provider. US/Canada toll-free numbers may have limited delivery to Guyana. Use dedicated long codes or short codes for better reliability.

Q: How do I track message delivery status?

A: Configure delivery webhooks in your provider dashboard. Webhooks send HTTP POST requests to your endpoint with delivery status (delivered, failed, undelivered) and timestamps.

Q: What's the difference between transactional and marketing SMS pricing?

A: Pricing per message is typically the same, but marketing SMS requires sender ID registration and opt-in consent. Transactional SMS (OTPs, alerts) often has faster delivery routing.

Q: Are there time restrictions for sending SMS in Guyana?

A: No strict legal restrictions, but best practice is to send marketing messages between 9 AM – 8 PM local time (Guyana Time/GYT, UTC-4) to avoid complaints.

Q: How do I calculate total cost for my SMS campaign?

Formula: Total Cost = (Total Characters ÷ Segment Size) × Messages × Rate per Segment

Example: 5,000 marketing messages, 140 characters with emoji (Unicode):

• Segments per message: 140 ÷ 67 = 3 segments
• Total segments: 5,000 × 3 = 15,000 segments
• Cost at $0.06/segment: 15,000 × $0.06 = $900

Q: What should I do if delivery rates are low?

1. Verify number format (E.164)
2. Check sender ID registration status
3. Test across all local carriers (GTT, Digicel, OneComm)
4. Review message content for spam triggers
5. Confirm recipients haven't opted out
6. Contact your provider to verify carrier routes

Q: Can I use the same SMS API code for multiple countries?

A: Yes. Most international providers support 200+ countries with the same API. Change the destination number's country code. Pricing and delivery rates vary by country.
