Before you begin
Important timelines
Signature review: If you submit during business hours, approval takes at least 24 hours.
Template review: It is expected to take 2 to 4 hours.
Sender ID registration: The time required varies based on the registration and compliance requirements of each country or region. For details, refer to the registration page in the console.
Billing
You are charged only when you send a message. SMS offers two billing models: pay-as-you-go and resource packages. Choose the option that best suits your needs. For more information, see Billing.
If you have a resource package, the system uses its quota first. When the quota is exhausted, subsequent messages are charged on a pay-as-you-go basis, and fees are deducted from your account balance.
Limitations
You cannot query mobile originated (MO) messages using the API or console. They can only be received by configuring callbacks.
Rate limit: You can send up to 20 messages to a single phone number per day.
