Is there a limit to the number of 4S group texting?

Mass texting by mobile phone has nothing to do with the model of mobile phone. It is the operator that limits the number of messages sent. Under normal circumstances, each mobile phone sends no more than 30 messages per hour and no more than 200 messages per day, but beyond this number, the SMS function may be turned off by the operator, and then it can only be unlocked in the business hall, which is more troublesome. Of course, 200 messages are just a normal reference, depending on your local operator. If you need to send a large number, you can look at the onesmser SMS platform.
