ShortySMS Plans and pricing

ShortySMS can work only with Twilio numbers (twilio.com)

That said, there are 2 options:

1. You can use your own Twilio number (purchase it on twiliio.com), connect it with ShortySMS and send all the messages using our interface and all the features we offer. In that case, you will need a Lifetime plan for ShortySMS, and you will be charged for every message by Twilio on your Twilio account.

2. You can use your existing phone number that's ported into Twilio.com. Here's Twilio's guide on how to port a phone number. Twilio may apply.
