- Trial Account Limitations: Trial accounts can only send messages to verified phone numbers. You must verify recipient numbers in the console or upgrade to a paid account for unrestricted messaging.
- Message Segment Pricing: SMS messages are billed per segment (160 characters for GSM, 70 for Unicode). Long messages are split into multiple segments. Monitor message length to control costs.
-
Webhook Signature Verification: Always validate webhook requests using the
X-Twilio-Signatureheader and your Auth Token to prevent spoofed requests. - Rate Limits Vary by Product: SMS sending has different rate limits per phone number and account. Voice calls have concurrent call limits. Monitor usage and request limit increases if needed.
