Application-to-person SMS is the text message your platform sends to a customer: a verification code, a delivery update, an appointment reminder. Callivex sends it from the account you already use for calls, paid from the same balance, with the sender identity screened before the first message leaves.
One-time passcodes for sign-in, sign-up and payment confirmation. Send the code with one call to the API, or let us generate and check it for you.
Order confirmations, delivery windows, appointment reminders, balance and security alerts. Each message carries a delivery receipt back to your system.
Messages arrive from your brand name or from a number on your account. Every sender identity is screened and approved before it is used, and per-country rules are applied for you.
The API is small on purpose. Send a message, or send a verification code and check the answer. Delivery status is posted to your endpoint as it changes, and every message is listed in the console with its state and cost.
SMS is switched on for an existing account, not sold as a separate product with its own login. Messages are charged per segment from the same prepaid balance as your calls, shown on the same balance page, and stop at the same cut-off.
SMS is added to an account that already exists, or requested alongside voice when you apply.
