Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
SMSBOX is a cloud-based SMS gateway from Belgian company JAAN bv, founded in 2000. It is designed for teams sending bulk campaigns, transactional notifications and OTP messages through a browser, REST API or SDKs. Campaigns can use Excel or CSV imports, contact groups, personalization and scheduling. The service also supports inbound SMS and two-way conversations, making it relevant for businesses that need replies as well as outbound delivery. It supports delivery to more than 200 countries.
The prepaid credit model is central to SMSBOX. A test account includes free test credits with no credit card required. Paid options start at 24.75 EUR for 250 credits, followed by 47 EUR for 500 credits, 89 EUR for 1,000 credits, 420 EUR for 5,000 credits, 790 EUR for 10,000 credits, 1,725 EUR for 25,000 credits and 3,200 EUR for 50,000 credits. The published plans show SMS, voice and WhatsApp usage on the starter tier, while larger tiers provide volume pricing. According to the pricing details, prices exclude Belgian VAT and vary by destination, message length and volume.
Its strongest fit is for organizations that need more than one-way bulk sending. Delivery reports are available in the dashboard, with webhook status updates for connected workflows. Incoming messages can be received through shared keywords, virtual numbers, hosted SIM cards or a shortcode, then viewed in the dashboard or forwarded by webhook or email. Integrations include Zapier, Make, WordPress, WooCommerce, Microsoft Teams, Microsoft Entra ID, Mail2SMS and SMPP. Choose SMSBOX for prepaid messaging with inbound tools and API access; consider another option if an ongoing free plan or simpler pricing is the priority.
