These answers cover standard platform behavior. Country-specific or account-specific rules may differ.
Contact supportA Sender ID is the name recipients see as the sender of an SMS. Availability and registration rules vary by country. Alphanumeric Sender IDs are generally limited to 11 characters, and our team can help confirm the exact requirements for your route.
A standard GSM-7 message can contain up to 160 characters. A Unicode message, including most Cyrillic text, can contain up to 70 characters. Longer messages are split into concatenated parts and each part is billed separately.
Yes. REST API is a practical choice for product notifications, OTP and transactional flows. SMPP 3.4 is available for professional, higher-volume messaging. The dashboard can be used for manual campaigns and operational review.
Use the international format with country code, for example 380XXXXXXXXX. Avoid local prefixes. Contact imports can be prepared as CSV or text files, and the workspace helps normalize common formatting characters.
Message history and reports in the dashboard show delivery states and timestamps. API and SMPP integrations can also receive delivery reports for automated processing.
Your available balance is visible in the dashboard. Online payment methods are available for eligible accounts, while contract customers can arrange invoice-based top-ups with the finance team.
Messages must comply with the law and operator policies in every destination. Phishing, smishing, illegal products, deceptive content and other prohibited categories are not allowed. Additional restrictions may apply to gambling, financial services, political or regulated content.
