SMS delivery has become problematic and inconsistent, with some popular carriers using the current Email to SMS gateway set up. Carriers are throttling or delaying delivery, blocking them entirely and in some cases delivering the message but sending a bounce back. Additionally, due to the wide variety of budget carriers or carriers who use multiple networks, we are not able to confidently offer SMS notices to those patrons.
We need to investigate and explore new SMS delivery methods development to maintain this functionality, including tie-ins to 3rd party carriers as well as better native options in Evergreen.
