I have a Twilio trial account, and I've been testing a web app for receiving SMS. I've assigned a URL for the inbound SMS messages, and that's been working fine. So far I haven't encountered any limitations on how many SMS messages I can receive, how fast, or anything like that. I didn't find anything on the Twilio website about this, either.
What is the limit, if anything, that my trial account has on receiving SMS messages? I don't need to send a response to the SMS sender, so I'm not worried about the cost to send SMS, or the "Sent by Twilio" that gets appended to a sent SMS.
