When sending SMS using Tencent Cloud SMS, there are differences between domestic (within China) and international messaging in terms of coverage, pricing, and regulations.
Coverage:
- Domestic SMS: Tencent Cloud SMS can send messages to any mobile number within China. This includes all the major Chinese mobile operators such as China Mobile, China Unicom, and China Telecom.
- International SMS: For international messaging, Tencent Cloud SMS supports sending SMS to mobile numbers in many countries around the world. However, coverage varies by country, and it's essential to check the specific countries supported before sending messages.
Pricing:
- Domestic SMS: Prices for domestic SMS are generally lower due to the local nature of the network infrastructure. Tencent Cloud SMS offers competitive rates for domestic messaging.
- International SMS: International SMS rates are higher because they involve crossing borders with different regulations and costs. The price per message can vary significantly depending on the destination country.
Regulations:
- Domestic SMS: Domestic messaging is subject to regulations set by the Chinese government, including restrictions on content and sending frequency to prevent spam.
- International SMS: International messaging is governed by the regulations of both the sending country (China) and the receiving country. This can include restrictions on content, sending volumes, and requirements for sender identification.
Example:
- If a company in Beijing wants to send a promotional offer to customers within China, they would use Tencent Cloud SMS's domestic service, which would be priced according to the domestic rate and comply with Chinese regulations.
- If the same company wants to send a welcome message to new users in the United States, they would use the international service of Tencent Cloud SMS. The cost would be higher, and they would need to ensure compliance with both Chinese and U.S. regulations regarding SMS messaging.
For businesses looking to leverage SMS services for global reach, Tencent Cloud SMS provides a comprehensive solution with extensive international coverage and competitive pricing.
