FAQs

Frequently Asked

Questions

Where is your service available, and what are the compliance requirements?

Our service is designed to support your global business expansion:

Global Coverage: Our network seamlessly spans over 220 countries and regions, with direct connections to premium carriers to ensure reliable message delivery worldwide.

Compliance Support: We actively comply with local regulations to help minimize your risks. For example, in the United States, we support 10DLC registration for compliant A2P messaging. In all operations, we strictly adhere to regulations such as the GDPR in the EU, and we require our customers to manage user consent responsibly as well.

What Sender IDs or numbers can I use to send SMS?

Sender identity regulations vary by country and region:

Alphanumeric Sender ID: In many regions (e.g., Europe and parts of Asia), you can register a custom alphanumeric ID to enhance brand recognition. Please note that this is not supported globally (e.g., the US and Canada primarily use numeric codes) and typically requires approval from local carriers.

Dedicated Short Code: Short codes are ideal for high-volume, high-priority scenarios such as marketing campaigns and mass notifications. The acquisition process involves application, vetting, and leasing fees. It usually takes several weeks to complete. Our team is here to assist you through the application process for specific countries.

Learn more about Sender ID requirements.

How is pricing structured?

We offer prepaid SMS packages that automatically deduct costs based on successfully delivered messages. Prices vary by destination country/region. You can view detailed pricing for all supported areas on our official pricing page.

What types of messages can I send, and are there any restrictions?

We fully support your communication needs while following guidelines to maintain deliverability:

Message Types: You can send OTPs, system alerts, marketing promotions, and more.

Content Policies: All message templates must be approved before sending to ensure they comply with carrier policies.

Encoding & Length: Standard SMS length depends on encoding. Messages using GSM-7 encoding have a limit of 160 characters per segment, while UCS-2 encoding (used for Chinese, emojis, etc.) supports up to 70 characters per segment. Longer messages are automatically split into multiple segments and billed accordingly.

Learn more about message length and billing.

Do you offer free trial credits? What developer resources are available?

To ensure the reliability and stability of our production environment, we do not currently offer free trial SMS credits. We recommend starting with a small prepaid package for testing—remaining balance can be refunded at any time, making it a low-cost way to validate our service.

We also provide comprehensive integration resources to accelerate your development, including detailed API documentation, SDKs in multiple programming languages, step-by-step guides, and an active developer community—everything you need to integrate quickly and smoothly.
