What amount of SMS per day do you recommend? I’ve read that a certain number of SMS may get a number blocked.
|It really depends on many factors, for example carriers have their own rules on how to block a phone number. It also depends for example if you are using a regular long distance phone number, or a toll free phone number. With a regular long distance phone number you could send 1 SMS per second, but with a toll free you could send over 20 SMS per second|
