Control SMS Send Rate

Whether you're sending hundreds or thousands of messages, our intelligent queue system ensures reliable delivery at your chosen pace.

The httpSMS application allows you to apply backpressure and send out SMS messages at a predictable rate which is configurable under the application settings. This means for example if you set the rate at 10 SMS per minute it means the httpSMS application will send out 1 SMS every 10 seconds since there are 60 seconds in 1 minute.

Modify SMS per minute send rate

To modify the rate of sending SMS messages per phone number under the settings page https://httpsms.com/settings and tap on the "EDIT" button on the phone number and you will be able to update the "Messages Per Minute". By default, when you register a new Android Phone on the httpSMS app, the SMS send rate is 10 SMS per minute but you can increase this up to 29 SMS per minute which is the maximum permitted by an unrooted android phone.

The Messages Per Minute setting affects single SMS messages sent via the API and bulk SMS messages sent by uploading an excel file.
