What it is
SMSBOX is a cloud messaging service for professional use through a web dashboard, REST API, or Windows access. It supports bulk SMS, one-time passcodes, WhatsApp Business messages, voice calls, email-to-SMS, and scheduled sending. The dashboard imports Excel contacts, applies personalization tags, schedules messages, and tracks results in real time. The API adds sending and receiving SMS, OTP verification, HLR number validation, voice messages, inbound webhooks, and delivery reports. SMSBOX says it reaches more than 200 countries and has direct operator connections in Belgium and the Netherlands. The maker lists more than 50 direct integrations and over 6,000 apps through Zapier, including WordPress, WooCommerce, Microsoft Teams, and Azure/Entra ID. JAAN says data is stored in Belgian EU data centers under GDPR. Credits last one year. Messages hold up to 160 GSM-7 or 70 Unicode characters before longer texts count as multiple messages. Test credits are free; arbitrary-number sending costs from €0.06 per SMS.
