By default, the Telerivet Gateway app is limited to sending only 30 outgoing SMS messages every half-hour. Telerivet's SMS Expansion Packs allow you to increase this limit up to the maximum sending rate of your phone hardware, which is typically about 900 SMS messages per half-hour.

Each SMS Expansion Pack enables Telerivet to send up to 30 additional outgoing SMS messages per half-hour. Start with SMS Expansion Pack 1, and install as many packs as you need for your expected usage.
