Yes, you can definitely do that. However, the your caller ID will be that of the phone number assigned to you. Upgraded accounts will have the ability to customize their caller ID.
OK, is pricing the same for sending SMS with the trial? Sorry I'm having a hard time figuring out what is free.
the price for sending out an SMS is technically the same for the trial account, but you won't be paying for it :)
Wait, so I can use this API to send free SMS messages? The limitation is that I'm locked down to 1 phone #?
@tehwebguy Yes, that's right. We want you to use Plivo to the fullest.
