ThaiBulkSMS review
Prepaid bulk SMS and OTP with web tools, API access, and delivery reporting.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
ThaiBulkSMS provides businesses with a web console and API for sending bulk SMS, marketing messages, alerts, and OTPs. Its SMS gateway connects to major Thai mobile operators, with tools for reviewing delivery reports and campaign results. It suits organizations sending messages to recipients in Thailand, from smaller teams to enterprise buyers, that want both campaign sending and API-based workflows. It is less suited to teams that need a clearly specified inbound messaging workflow.
Packages are prepaid and sold as one-time purchases rather than recurring monthly plans. At ฿1,500, Standard SMS includes 3,061 credits plus 20% promotional credits and 5 sender names; Corporate SMS includes 2,586 credits plus 20% and the same sender-name allowance. At ฿3,500, the Standard package has 8,537 credits and the Corporate package 7,292, each plus 20%, with 10 sender names. At ฿10,000, those credit amounts are 27,027 and 23,256, with 15 sender names. The ฿30,000 options provide 93,750 Standard credits or 78,947 Corporate credits, both plus 20%, and unlimited sender names. Corporate packages include Standard features and advertise OTP and credit refunds for undelivered messages. Prices exclude VAT.
The API supports sending to one or multiple recipients and checking remaining credits, with API key and secret authentication described in its documentation. The web console adds scheduled delivery, delivery reports, campaign analytics, and recipient open-status checking. A free sending trial is offered, but the product is not presented as a continuing free plan. Choose ThaiBulkSMS when prepaid Thai-market sending, API access, and delivery visibility match the workflow; consider alternatives if inbound SMS is essential or if a recurring subscription model is required.
