You can send SMS messages in Thailand using international gateway providers like Twilio, Plivo, Sinch, and Infobip, or local Thai carriers like AIS, True Move H, and DTAC. International gateways offer robust features and global reach, while local carriers provide competitive rates for domestic messaging within Thailand.

Twilio charges $0.0250 per message segment for outbound SMS to Thailand. Inbound SMS is free with an international number. They also offer a free tier for the first 1,000 messages each month and volume discounts for high-volume users.

SMS pricing in Thailand varies due to factors like carrier agreements, regulatory changes, and market demand. International gateway providers and local Thai carriers have different pricing structures, influenced by their infrastructure and features.

Yes, but you need to register your alphanumeric Sender ID with the provider to ensure message delivery and maintain brand consistency. Thailand's regulations require pre-registration for alphanumeric Sender IDs.

Infobip charges $0.20825178 per message segment for outbound SMS to Thailand. Inbound SMS prices vary by number type. They offer extensive global reach and advanced messaging features, but at a premium price point.

Best practices include registering your alphanumeric Sender ID, leveraging volume discounts, monitoring usage and costs, and staying updated on regulations from the NBTC. It's important to adhere to sending time restrictions and content restrictions.

Thailand's regulations, overseen by the NBTC, include restrictions on content (e.g., no gambling or adult content), sending times (no marketing messages between 9 PM and 9 AM), and pre-registration of alphanumeric Sender IDs.

Sinch offers competitive inbound SMS rates at $0.009 per message in Thailand. Outbound rates are competitive but require contacting Sinch directly for specific pricing.

Plivo offers flexible API integration, reliable delivery infrastructure, and enterprise-grade security. They also provide custom pricing for high-volume users sending SMS to Thailand.

Local Thai carriers like AIS, True Move H, and DTAC typically charge 1-2 THB per domestic SMS and 5-10 THB per international SMS. They also offer bundle packages and business-specific pricing plans.
