SmsManager.cz is a Czech business messaging platform centered on an SMS gateway, with additional support for WhatsApp, Viber, RCS, SMS PIN/2FA, and SIM hosting. It offers a web-based bulk messaging dashboard that requires no installation, as well as JSON API, REST API, SDKs, and automation integrations for developers.
In terms of channels, the platform supports combined delivery via SMS, WhatsApp, Viber, and RCS. For example, you can try WhatsApp first and fall back to SMS to reduce costs. For coverage, its materials state that messages can be sent to 200+ countries, and it highlights cooperation with all Czech mobile operators, making it especially credible for the Czech and surrounding markets. On performance, messages are routed into different queues: the priority queue reportedly delivers in about 1 second on average, while standard scenarios are said to complete within a few seconds. It also provides real-time delivery statistics, webhooks, and logs. On the API side, its JSON API documentation, Sandbox, multilingual examples, and libraries for PHP/Node.js/Ruby and others are fairly complete, with support for tools such as Zapier, Make, n8n, Klaviyo, and Bloomreach.
Registration and account maintenance are free, and billing is based on actual sending usage. Credits do not expire. Rates decrease automatically as sending volume increases. Reference prices given in the materials include SMS from as low as 0.60 KΔ/message and WhatsApp transactional messages from as low as 0.54 KΔ/message. Text sender IDs require operator registration, costing a one-time 500 KΔ plus 500 KΔ per month. Viber has a minimum threshold of 10,000 delivered messages, or around 3900 KΔ, making it more suitable for medium to large-scale sending.
Its strengths include mature multi-channel orchestration, developer-friendly APIs, complete real-time delivery receipts, and assistance with registering RCS or WhatsApp Business API. Its marketing features are also practical, including variable templates, scheduled sending, automatic unsubscribe, an 8:00-20:00 marketing sending window, and invalid-number filtering. The downsides are that the public pages do not provide complete country-by-country rates, a formal SLA, or detailed GDPR information. WhatsApp also depends on a Facebook Business Account and template approval, while Viber is not very friendly to smaller customers.
SmsManager.cz is better suited for businesses in the Czech Republic, Slovakia, and Europe, as well as e-commerce companies, CRM/marketing automation teams, and developers needing 2FA or notification APIs. The source material does not state how well it works from mainland China, and network connectivity plus support for domestic Chinese bank cards or RMB payments are unknown. If your main audience is in China, it is recommended to first compare Alibaba Cloud SMS, Tencent Cloud SMS, Huawei Cloud SMS, or international alternatives such as Twilio, Infobip, Sinch, and MessageBird.
